87272375 ÷ 861 
We want to figure out the number of times 87272375 can be divided by 861.

On to step 1:
8 divided by 861 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 861

Going ahead to step 2:
The number 861 fits into 87 0 times, leaving a remainder of 87.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 87 and we're left with 87.
Include the next digit (2) from the dividend after 87, then repeat: 872 / 861

Let's proceed to step 3:
861 can be fit into 872 1 times, resulting in a remainder of 11.
The next digit of our result is 1. 
Result so far: 1.0
If we take 861 away from 872, we end up with 11.
Append the next digit (7) from the dividend to 11 and continue with: 117 / 861

Step 4:
If we divide 117 by 861, we get 0 and a remainder of 117.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Deduct 0 from 117 and we're left with 117.
Include the next digit (2) from the dividend after 117, then repeat: 1172 / 861

Advancing to step 5:
If we divide 1172 by 861, we get 1 and a remainder of 311.
Use 1 as the next digit of our solution. 
Result so far: 101.0
Deduct 861 from 1172 and we're left with 311.
Take the next digit (3) from the dividend and append it to 311, then repeat: 3113 / 861

On to step 6:
The number 861 fits into 3113 3 times, leaving a remainder of 530.
The number 3 becomes the next digit in our result. 
Result so far: 1013.0
If we take 2583 away from 3113, we end up with 530.
Fetch the next digit (7) from the dividend, attach it to 530 and continue: 5307 / 861

Step 7:
If we divide 5307 by 861, we get 6 and a remainder of 141.
The next digit of our result is 6. 
Result so far: 10136.0
Subtract 5166 from 5307 to get 141.
Fetch the next digit (5) from the dividend, attach it to 141 and continue: 1415 / 861

Step 8:
If we divide 1415 by 861, we get 1 and a remainder of 554.
Put 1 as the next digit of the answer. 
Result so far: 101361.0
Subtracting 861 from 1415 leaves us with 554.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5540, and continue the process.

Let's proceed to step 9:
861 goes into 5540 6 times with a remainder of 374.
The number 6 becomes the next digit in our result. 
Result so far: 101361.6
If we subtract 5166 from 5540, we get 374.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3740, and continue the process.

Moving on to step 10:
3740 divided by 861 is 4 with a remainder of 296.
The number 4 becomes the next digit in our result. 
Result so far: 101361.64
If we take 3444 away from 3740, we end up with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

On to step 11:
When dividing 2960 by 861, we get 3 with a remainder of 377.
Write down 3 as next digit of the result. 
Result so far: 101361.643
Subtract 2583 from 2960 to get 377.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3770, and continue the process.

Step 12:
3770 divided by 861 is 4 with a remainder of 326.
Put 4 as the next digit of the answer. 
Result so far: 101361.6434
If we take 3444 away from 3770, we end up with 326.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

Going ahead to step 13:
If we divide 3260 by 861, we get 3 and a remainder of 677.
The number 3 becomes the next digit in our result. 
Result so far: 101361.64343
Subtract 2583 from 3260 to get 677.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6770, and continue the process.

Moving on to step 14:
When dividing 6770 by 861, we get 7 with a remainder of 743.
Use 7 as the next digit of our solution. 
Result so far: 101361.643437
If we subtract 6027 from 6770, we get 743.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7430, and continue the process.

Going ahead to step 15:
If we divide 7430 by 861, we get 8 and a remainder of 542.
The next digit of our result is 8. 
Result so far: 101361.6434378
If we take 6888 away from 7430, we end up with 542.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5420, and continue the process.

Step 16:
861 can be fit into 5420 6 times, resulting in a remainder of 254.
The number 6 becomes the next digit in our result. 
Result so far: 101361.64343786
Subtract 5166 from 5420 to get 254.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

The final outcome is 101361.64343786, with a leftover of 2.54e-07.
