72886914 ÷ 861 
We want to figure out the number of times 72886914 can be divided by 861.

On to step 1:
The number 861 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 861

Going ahead to step 2:
When dividing 72 by 861, we get 0 with a remainder of 72.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 72 and we're left with 72.
Append the next digit (8) from the dividend to 72 and continue with: 728 / 861

Going ahead to step 3:
The number 861 fits into 728 0 times, leaving a remainder of 728.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 728 and we're left with 728.
Include the next digit (8) from the dividend after 728, then repeat: 7288 / 861

Step 4:
861 can be fit into 7288 8 times, resulting in a remainder of 400.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtract 6888 from 7288 to get 400.
Take the next digit (6) from the dividend and append it to 400, then repeat: 4006 / 861

Going ahead to step 5:
The number 861 fits into 4006 4 times, leaving a remainder of 562.
The number 4 becomes the next digit in our result. 
Result so far: 84.0
If we take 3444 away from 4006, we end up with 562.
Bring next digit (9) of the dividend behind the 562 and repeat the process: 5629 / 861

Step 6:
5629 divided by 861 is 6 with a remainder of 463.
The number 6 becomes the next digit in our result. 
Result so far: 846.0
If we subtract 5166 from 5629, we get 463.
Grab the next digit (1) from the dividend, add it to 463, then carry on: 4631 / 861

Step 7:
861 can be fit into 4631 5 times, resulting in a remainder of 326.
The next digit of our result is 5. 
Result so far: 8465.0
Deduct 4305 from 4631 and we're left with 326.
Include the next digit (4) from the dividend after 326, then repeat: 3264 / 861

Going ahead to step 8:
If we divide 3264 by 861, we get 3 and a remainder of 681.
Write down 3 as next digit of the result. 
Result so far: 84653.0
Deduct 2583 from 3264 and we're left with 681.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6810, and continue the process.

Moving on to step 9:
6810 divided by 861 is 7 with a remainder of 783.
The next digit of our result is 7. 
Result so far: 84653.7
Subtract 6027 from 6810 to get 783.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7830, and continue the process.

Going ahead to step 10:
861 can be fit into 7830 9 times, resulting in a remainder of 81.
The number 9 becomes the next digit in our result. 
Result so far: 84653.79
Subtract 7749 from 7830 to get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Moving on to step 11:
810 divided by 861 is 0 with a remainder of 810.
Record the quotient 0 as the next digit in the result. 
Result so far: 84653.79
If we take 0 away from 810, we end up with 810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8100, and continue the process.

Moving on to step 12:
The number 861 fits into 8100 9 times, leaving a remainder of 351.
The next digit of our result is 9. 
Result so far: 84653.7909
The remainder is 351 after subtracting 7749 from 8100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3510, and continue the process.

Advancing to step 13:
When dividing 3510 by 861, we get 4 with a remainder of 66.
Use 4 as the next digit of our solution. 
Result so far: 84653.79094
If we subtract 3444 from 3510, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Going ahead to step 14:
660 divided by 861 is 0 with a remainder of 660.
Put 0 as the next digit of the answer. 
Result so far: 84653.79094
Subtracting 0 from 660 leaves us with 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

On to step 15:
861 can be fit into 6600 7 times, resulting in a remainder of 573.
Write down 7 as next digit of the result. 
Result so far: 84653.7909407
If we subtract 6027 from 6600, we get 573.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5730, and continue the process.

Advancing to step 16:
The number 861 fits into 5730 6 times, leaving a remainder of 564.
Write down 6 as next digit of the result. 
Result so far: 84653.79094076
Subtracting 5166 from 5730 leaves us with 564.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5640, and continue the process.

After the division, we end up with 84653.79094076 and a remainder of 5.64e-07.
