We divide 81129943 by 28
We want to divide 81129943 by 28.

Step 1:
When dividing 8 by 28, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 28

On to step 2:
When dividing 81 by 28, we get 2 with a remainder of 25.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 56 from 81 to get 25.
Include the next digit (1) from the dividend after 25, then repeat: 251 / 28

Going ahead to step 3:
If we divide 251 by 28, we get 8 and a remainder of 27.
Record the quotient 8 as the next digit in the result. 
Result so far: 28.0
If we subtract 224 from 251, we get 27.
Bring next digit (2) of the dividend behind the 27 and repeat the process: 272 / 28

On to step 4:
If we divide 272 by 28, we get 9 and a remainder of 20.
The number 9 becomes the next digit in our result. 
Result so far: 289.0
Subtract 252 from 272 to get 20.
Grab the next digit (9) from the dividend, add it to 20, then carry on: 209 / 28

Step 5:
If we divide 209 by 28, we get 7 and a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 2897.0
Subtracting 196 from 209 leaves us with 13.
Fetch the next digit (9) from the dividend, attach it to 13 and continue: 139 / 28

On to step 6:
28 goes into 139 4 times with a remainder of 27.
Write down 4 as next digit of the result. 
Result so far: 28974.0
If we subtract 112 from 139, we get 27.
Append the next digit (4) from the dividend to 27 and continue with: 274 / 28

Going ahead to step 7:
28 goes into 274 9 times with a remainder of 22.
Write down 9 as next digit of the result. 
Result so far: 289749.0
Subtract 252 from 274 to get 22.
Grab the next digit (3) from the dividend, add it to 22, then carry on: 223 / 28

Let's proceed to step 8:
If we divide 223 by 28, we get 7 and a remainder of 27.
Use 7 as the next digit of our solution. 
Result so far: 2897497.0
Subtracting 196 from 223 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 9:
When dividing 270 by 28, we get 9 with a remainder of 18.
Put 9 as the next digit of the answer. 
Result so far: 2897497.9
Subtract 252 from 270 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 10:
28 goes into 180 6 times with a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 2897497.96
The remainder is 12 after subtracting 168 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 11:
28 can be fit into 120 4 times, resulting in a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 2897497.964
Subtracting 112 from 120 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 12:
If we divide 80 by 28, we get 2 and a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 2897497.9642
Subtracting 56 from 80 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 13:
28 can be fit into 240 8 times, resulting in a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 2897497.96428
The remainder is 16 after subtracting 224 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 14:
The number 28 fits into 160 5 times, leaving a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 2897497.964285
The remainder is 20 after subtracting 140 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 15:
28 goes into 200 7 times with a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 2897497.9642857
Deduct 196 from 200 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 16:
28 can be fit into 40 1 times, resulting in a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 2897497.96428571
If we take 28 away from 40, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Our division results in 2897497.96428571 with a remaining 1.2e-08.
