We're dividing 87186006 by 872 
Our goal is to divide 87186006 by 872.

Advancing to step 1:
When dividing 8 by 872, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 872

Advancing to step 2:
When dividing 87 by 872, we get 0 with a remainder of 87.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 87, we end up with 87.
Include the next digit (1) from the dividend after 87, then repeat: 871 / 872

Step 3:
When dividing 871 by 872, we get 0 with a remainder of 871.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 871, we end up with 871.
Take the next digit (8) from the dividend and append it to 871, then repeat: 8718 / 872

Step 4:
If we divide 8718 by 872, we get 9 and a remainder of 870.
Write down 9 as next digit of the result. 
Result so far: 9.0
Subtracting 7848 from 8718 leaves us with 870.
Grab the next digit (6) from the dividend, add it to 870, then carry on: 8706 / 872

Moving on to step 5:
8706 divided by 872 is 9 with a remainder of 858.
The next digit of our result is 9. 
Result so far: 99.0
Subtract 7848 from 8706 to get 858.
Fetch the next digit (0) from the dividend, attach it to 858 and continue: 8580 / 872

On to step 6:
872 goes into 8580 9 times with a remainder of 732.
Put 9 as the next digit of the answer. 
Result so far: 999.0
Subtract 7848 from 8580 to get 732.
Grab the next digit (0) from the dividend, add it to 732, then carry on: 7320 / 872

On to step 7:
872 goes into 7320 8 times with a remainder of 344.
The next digit of our result is 8. 
Result so far: 9998.0
If we take 6976 away from 7320, we end up with 344.
Fetch the next digit (6) from the dividend, attach it to 344 and continue: 3446 / 872

On to step 8:
The number 872 fits into 3446 3 times, leaving a remainder of 830.
Put 3 as the next digit of the answer. 
Result so far: 99983.0
If we take 2616 away from 3446, we end up with 830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8300, and continue the process.

Moving on to step 9:
When dividing 8300 by 872, we get 9 with a remainder of 452.
Use 9 as the next digit of our solution. 
Result so far: 99983.9
The remainder is 452 after subtracting 7848 from 8300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

Advancing to step 10:
When dividing 4520 by 872, we get 5 with a remainder of 160.
Record the quotient 5 as the next digit in the result. 
Result so far: 99983.95
If we subtract 4360 from 4520, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Let's proceed to step 11:
872 goes into 1600 1 times with a remainder of 728.
Put 1 as the next digit of the answer. 
Result so far: 99983.951
The remainder is 728 after subtracting 872 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7280, and continue the process.

Going ahead to step 12:
The number 872 fits into 7280 8 times, leaving a remainder of 304.
The next digit of our result is 8. 
Result so far: 99983.9518
The remainder is 304 after subtracting 6976 from 7280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Moving on to step 13:
When dividing 3040 by 872, we get 3 with a remainder of 424.
Write down 3 as next digit of the result. 
Result so far: 99983.95183
Subtract 2616 from 3040 to get 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

Advancing to step 14:
872 goes into 4240 4 times with a remainder of 752.
Record the quotient 4 as the next digit in the result. 
Result so far: 99983.951834
If we subtract 3488 from 4240, we get 752.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7520, and continue the process.

Step 15:
872 can be fit into 7520 8 times, resulting in a remainder of 544.
The next digit of our result is 8. 
Result so far: 99983.9518348
If we take 6976 away from 7520, we end up with 544.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

Advancing to step 16:
The number 872 fits into 5440 6 times, leaving a remainder of 208.
The number 6 becomes the next digit in our result. 
Result so far: 99983.95183486
Subtract 5232 from 5440 to get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

After the division, we end up with 99983.95183486 and a remainder of 2.08e-07.
