86971802 divided by 879 
Our goal is to divide 86971802 by 879.

Going ahead to step 1:
When dividing 8 by 879, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 879

Step 2:
86 divided by 879 is 0 with a remainder of 86.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 86, we end up with 86.

Step 3:
When dividing 869 by 879, we get 0 with a remainder of 869.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 869 leaves us with 869.
Take the next digit (7) from the dividend and append it to 869, then repeat: 8697 / 879

Moving on to step 4:
879 goes into 8697 9 times with a remainder of 786.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtracting 7911 from 8697 leaves us with 786.
Bring next digit (1) of the dividend behind the 786 and repeat the process: 7861 / 879

Going ahead to step 5:
7861 divided by 879 is 8 with a remainder of 829.
The next digit of our result is 8. 
Result so far: 98.0
Subtract 7032 from 7861 to get 829.
Take the next digit (8) from the dividend and append it to 829, then repeat: 8298 / 879

Let's proceed to step 6:
The number 879 fits into 8298 9 times, leaving a remainder of 387.
The next digit of our result is 9. 
Result so far: 989.0
Subtract 7911 from 8298 to get 387.
Bring next digit (0) of the dividend behind the 387 and repeat the process: 3870 / 879

Advancing to step 7:
879 goes into 3870 4 times with a remainder of 354.
The number 4 becomes the next digit in our result. 
Result so far: 9894.0
If we take 3516 away from 3870, we end up with 354.
Include the next digit (2) from the dividend after 354, then repeat: 3542 / 879

On to step 8:
3542 divided by 879 is 4 with a remainder of 26.
Write down 4 as next digit of the result. 
Result so far: 98944.0
If we take 3516 away from 3542, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 9:
When dividing 260 by 879, we get 0 with a remainder of 260.
The next digit of our result is 0. 
Result so far: 98944.0
Subtract 0 from 260 to get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Going ahead to step 10:
2600 divided by 879 is 2 with a remainder of 842.
The number 2 becomes the next digit in our result. 
Result so far: 98944.02
If we subtract 1758 from 2600, we get 842.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8420, and continue the process.

Advancing to step 11:
879 can be fit into 8420 9 times, resulting in a remainder of 509.
The number 9 becomes the next digit in our result. 
Result so far: 98944.029
Deduct 7911 from 8420 and we're left with 509.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5090, and continue the process.

Let's proceed to step 12:
5090 divided by 879 is 5 with a remainder of 695.
Record the quotient 5 as the next digit in the result. 
Result so far: 98944.0295
If we take 4395 away from 5090, we end up with 695.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6950, and continue the process.

Moving on to step 13:
When dividing 6950 by 879, we get 7 with a remainder of 797.
Record the quotient 7 as the next digit in the result. 
Result so far: 98944.02957
The remainder is 797 after subtracting 6153 from 6950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7970, and continue the process.

Step 14:
879 goes into 7970 9 times with a remainder of 59.
Record the quotient 9 as the next digit in the result. 
Result so far: 98944.029579
If we take 7911 away from 7970, we end up with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Moving on to step 15:
590 divided by 879 is 0 with a remainder of 590.
The number 0 becomes the next digit in our result. 
Result so far: 98944.029579
Subtract 0 from 590 to get 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

Advancing to step 16:
879 can be fit into 5900 6 times, resulting in a remainder of 626.
Put 6 as the next digit of the answer. 
Result so far: 98944.02957906
If we subtract 5274 from 5900, we get 626.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6260, and continue the process.

The final result is 98944.02957906 with a remainder of 6.26e-07.
