We look at the division of 87156880 by 81 
We want to divide 87156880 by 81.

Let's proceed to step 1:
When dividing 8 by 81, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 81

Advancing to step 2:
The number 81 fits into 87 1 times, leaving a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 81 from 87 leaves us with 6.
Bring next digit (1) of the dividend behind the 6 and repeat the process: 61 / 81

Going ahead to step 3:
If we divide 61 by 81, we get 0 and a remainder of 61.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtracting 0 from 61 leaves us with 61.
Bring next digit (5) of the dividend behind the 61 and repeat the process: 615 / 81

Let's proceed to step 4:
When dividing 615 by 81, we get 7 with a remainder of 48.
Use 7 as the next digit of our solution. 
Result so far: 107.0
The remainder is 48 after subtracting 567 from 615.
Include the next digit (6) from the dividend after 48, then repeat: 486 / 81

Moving on to step 5:
When dividing 486 by 81, we get 6 with a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 1076.0
Subtracting 486 from 486 leaves us with 0.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 81

On to step 6:
81 can be fit into 8 0 times, resulting in a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 10760.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (8) from the dividend to 8 and continue with: 88 / 81

Advancing to step 7:
81 can be fit into 88 1 times, resulting in a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 107601.0
The remainder is 7 after subtracting 81 from 88.
Bring next digit (0) of the dividend behind the 7 and repeat the process: 70 / 81

Going ahead to step 8:
81 can be fit into 70 0 times, resulting in a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 1076010.0
If we take 0 away from 70, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 9:
When dividing 700 by 81, we get 8 with a remainder of 52.
Use 8 as the next digit of our solution. 
Result so far: 1076010.8
Subtract 648 from 700 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 10:
520 divided by 81 is 6 with a remainder of 34.
Write down 6 as next digit of the result. 
Result so far: 1076010.86
The remainder is 34 after subtracting 486 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 11:
If we divide 340 by 81, we get 4 and a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 1076010.864
Subtract 324 from 340 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 12:
81 goes into 160 1 times with a remainder of 79.
Use 1 as the next digit of our solution. 
Result so far: 1076010.8641
Subtracting 81 from 160 leaves us with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

On to step 13:
81 can be fit into 790 9 times, resulting in a remainder of 61.
Use 9 as the next digit of our solution. 
Result so far: 1076010.86419
If we subtract 729 from 790, we get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Advancing to step 14:
81 can be fit into 610 7 times, resulting in a remainder of 43.
The next digit of our result is 7. 
Result so far: 1076010.864197
If we subtract 567 from 610, we get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Let's proceed to step 15:
81 goes into 430 5 times with a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 1076010.8641975
If we subtract 405 from 430, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 16:
The number 81 fits into 250 3 times, leaving a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 1076010.86419753
If we take 243 away from 250, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

After the division, we end up with 1076010.86419753 and a remainder of 7e-09.
