We're dividing 76139096 by 879 
We want to divide 76139096 by 879.

Going ahead to step 1:
879 goes into 7 0 times with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (6) from the dividend to 7 and continue with: 76 / 879

Advancing to step 2:
879 can be fit into 76 0 times, resulting in a remainder of 76.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 76, we end up with 76.
Include the next digit (1) from the dividend after 76, then repeat: 761 / 879

Step 3:
761 divided by 879 is 0 with a remainder of 761.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 761, we get 761.
Append the next digit (3) from the dividend to 761 and continue with: 7613 / 879

Let's proceed to step 4:
879 can be fit into 7613 8 times, resulting in a remainder of 581.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we take 7032 away from 7613, we end up with 581.
Take the next digit (9) from the dividend and append it to 581, then repeat: 5819 / 879

Going ahead to step 5:
The number 879 fits into 5819 6 times, leaving a remainder of 545.
The number 6 becomes the next digit in our result. 
Result so far: 86.0
If we subtract 5274 from 5819, we get 545.
Append the next digit (0) from the dividend to 545 and continue with: 5450 / 879

Step 6:
The number 879 fits into 5450 6 times, leaving a remainder of 176.
Record the quotient 6 as the next digit in the result. 
Result so far: 866.0
Subtracting 5274 from 5450 leaves us with 176.
Append the next digit (9) from the dividend to 176 and continue with: 1769 / 879

Moving on to step 7:
1769 divided by 879 is 2 with a remainder of 11.
Put 2 as the next digit of the answer. 
Result so far: 8662.0
Subtracting 1758 from 1769 leaves us with 11.
Append the next digit (6) from the dividend to 11 and continue with: 116 / 879

On to step 8:
If we divide 116 by 879, we get 0 and a remainder of 116.
Put 0 as the next digit of the answer. 
Result so far: 86620.0
The remainder is 116 after subtracting 0 from 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Let's proceed to step 9:
879 goes into 1160 1 times with a remainder of 281.
Write down 1 as next digit of the result. 
Result so far: 86620.1
Subtract 879 from 1160 to get 281.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2810, and continue the process.

Let's proceed to step 10:
879 can be fit into 2810 3 times, resulting in a remainder of 173.
Use 3 as the next digit of our solution. 
Result so far: 86620.13
Subtract 2637 from 2810 to get 173.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1730, and continue the process.

Step 11:
879 goes into 1730 1 times with a remainder of 851.
Put 1 as the next digit of the answer. 
Result so far: 86620.131
Deduct 879 from 1730 and we're left with 851.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8510, and continue the process.

Step 12:
879 can be fit into 8510 9 times, resulting in a remainder of 599.
The next digit of our result is 9. 
Result so far: 86620.1319
Subtract 7911 from 8510 to get 599.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5990, and continue the process.

Going ahead to step 13:
When dividing 5990 by 879, we get 6 with a remainder of 716.
The number 6 becomes the next digit in our result. 
Result so far: 86620.13196
Deduct 5274 from 5990 and we're left with 716.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7160, and continue the process.

On to step 14:
879 can be fit into 7160 8 times, resulting in a remainder of 128.
Write down 8 as next digit of the result. 
Result so far: 86620.131968
If we subtract 7032 from 7160, we get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Step 15:
When dividing 1280 by 879, we get 1 with a remainder of 401.
Write down 1 as next digit of the result. 
Result so far: 86620.1319681
The remainder is 401 after subtracting 879 from 1280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4010, and continue the process.

Advancing to step 16:
879 can be fit into 4010 4 times, resulting in a remainder of 494.
Put 4 as the next digit of the answer. 
Result so far: 86620.13196814
Subtract 3516 from 4010 to get 494.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4940, and continue the process.

The final result is 86620.13196814 with a remainder of 4.94e-07.
