how do you do long division?

Answer 1

Take the number put it into an upside down L, turned 90 degrees to the right, put the number to be divided in the L, then on the left you have the divider, see how many times it goes into the 1st 2 or 3 digits, write the answer on the lop line of the L, then do the next digits with the remainder put in and add that next to the number on the top, and that top number is the answer

EG

7 / 434 seven doesnt go into 4 but it does 6 times into 42 so put 6 on top of the 3, I haven't got the line there but you know what I mean, write 42 under the 43 subtract from 43 answer is 1 ,
bring down the 4 next to the 1, 7 goes into 14 twice, so put 2 about the 2nd 4 subtract 14 from 14 answer is 00, so your long division answer is 14

Answer 2

I like to think of it as repeated subtraction. Here's an example.

156/20. How many 20's can you take out before you hit zero? Let's take out 5 of them. 5*20-100, and 156 -100=56, so now we have the new question, "how many 20's can you take out of 56?" Looks like 2, with 16 left over. So the answer is 5+2=7 with a remainder of 16, or 7 +16/20.

You can use decimals to continue the long division and get a decimal for 16/20 if you want. The trick there is to first multiply 16 by 10 to get 160, then find how many 20's go into 160, then divide that answer by 10. If the fraction were instead 7/100, you'd have to multiply the 7 by 100 then divide it by 100 at the end.

Answer 3

Difficult to explain like this.
_________
5 | 68794

First you divide 6 by 5 giving 1, you write this over the 6 and place 5 under it and take it away leaving 1. Drop the 8 down next to the 1 to give 18 and divide by 5 (=3). Place the 3 over the 8 (at the top) and place 15 (your 3 lots of 5) under the 18 and subtract giving 3. Drop the 7 next to the 3 to give 37 and divide by 5 (=7). Place 7 over the top 7 etc.

It was a bit difficult to lay it out but I tried my best. At the end you can bring down a 0 and calculate to decimal places.

I don't know why but all the indenting that I did failed to come out so the layout looks radically different.

E-mail me if you require further assistance and I'll see what I can do.

Answer 4

Difficult to explain without a graphics program - I'll try.

Assuming this is the problem ____
7 ) 24

You start by seeing whether 7 goes into 2 - which it doesn't so you bring in the next number and see if 7 goes into 24.
7 goes into 24 three times with 3 left over so you then add a decimal point after the 3
__3.___
7 ) 24
30
and add a zero to the remainder on the bottom. 7 then goes into 30 4 times with 2 left over so the top line will say 3.4 and you add a zero to the 2 and so 7 goes into 20 twice with 6 left over so the top line will say 3.42 then it goes 7 into 60 which is 8 with 4 left over so the top line says 3.428 and you carry on like that until you get a complete decimal or you get fed-up and round it off. Best I can do really. Sorry if I haven't been clearer.

Answer 5

243612/12 is long division. First of all divide the first two digits by 12 = 2 then the next digit = 0 then the next two = 3 then the next one 0 and finally the last two = 1 put them all together and 243612/12 = 20301. Just to check multiply 20301 X 12 = 203010 + 40602 = 243612. Easy really. You could use a calculator...

Answer 6

Long division

Example

20 ÷ 10 = 2

20 is the dividend

10 is the divisor

2 is the quotient

÷ is the division symbol

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

30 ÷ 5 = 6

30 is the dividend

5 is the divisor

6 is the quotient

÷ is the division symbol

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

Answer 7

Everybody makes it look complicated but it's really simple. Look at the divisor ( the number you are dividing by) Look at the dividend ( the number you are going to divide). Take a guess - how many times does divisor go into dividend. eg 527 divided by 17 - any dart player will tell you treble 17 = 51, so first number is 3. that gives you 527 - 510 = 17. 17/17 = 1. So answer = 31

Answer 8

Long division is short division done many times.

Answer 9

e.g. 4983 / 15

(ignore the ' I had to use them to make things line up)
''''''_____
15 | 4983

Look at the first digit of 4983, 15 will not go into 4 so look at the first two digits. 3 * 15 = 45 so this will go into 49 with 4 left over. Write the 45 under the 49 and write the 3 (for 15 will go into 49 3 times) above the 9.

'''''''__3__
15 | 4983
'''''''''45

The 49 and 45 turn into a mini-subtraction, 49 - 45 is 4 (what you had left over)

''''''__3__
15 | 4983
''''''''-45
'''''''''---
''''''''''''4

Now you look at the 4 and the next digit in 4983 which is 8. Bring the 8 down next to the 4.
''''''__3__
15 | 4983
''''''''-45
''''''''''---
''''''''''''48
Now you are trying to find how many 15s are in 48. It's 3 again, so write the 3 above the top 8 and 45(3*15) under the 48 to do the subtraction again. This time you have 3 left over.

''''''__33_
15 | 4983
'''''''-45
'''''''''---
'''''''''''48
''''''''''-45
''''''''''''---
'''''''''''''''3

Now look at the 3 you had left and the 3 at the end of 4983.

''''''__33_
15 | 4983
'''''''-45
'''''''''---
'''''''''''48
'''''''''-45
'''''''''''---
''''''''''''''33

There are two 15s in 33 so write 2 above the top 3 and 30 (2*15) under the 33, and do another subtraction.
''''''__332
15 | 4983
'''''''-45
'''''''''---
''''''''''''48
''''''''''-45
''''''''''''---
'''''''''''''''33
''''''''''''''-30
''''''''''''''----
''''''''''''''''''3

You now have 3 left over and no more digits of 4983, and 15 won't go into 3, so your answer is 332 remainder 3. If you want to go further then you can write a .0 after the 4983 and bring this down next to the 3 at the bottom. Then your final answer will be 322.2.

Answer 10

4m-a million | 12mmm +21mm -14m + 15 by way of fact it extremely is 12m^3 you realize the 1st area must be m^2 and four is going into 12 thrice. So attempt 3m^2 (4m-a million)(3m^2) = 12m^3 - 3m^2 + 12mmm + 21 mm - 12mmm + 3 mm (bear in mind the signs and indications could desire to alter by way of fact of minus) ---------------- 24 mm -14m + 15 now 4 is going into 24 6 cases and you want mm so multiply via m attempt: 6m (4m-a million)(6m) = 24mm -6m +24mm - 14m -24mm + 6 m ------------ - 8 m + 15 now 4 is going in -8 detrimental 2 cases and you in user-friendly terms want a million m so no could desire to multiply via an m attempt: -2 (4m-a million)(-2) = -8m + 2 -8m + 15 +8m - 2 ------------- 13 putting all of it jointly your very final answer is 3m^2 + 6m - 2 the rest 13
