We're dividing 79098759 by 879 
We want to figure out the number of times 79098759 can be divided by 879.

Going ahead to step 1:
When dividing 7 by 879, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (9) from the dividend after 7, then repeat: 79 / 879

Advancing to step 2:
879 goes into 79 0 times with a remainder of 79.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 79, we end up with 79.
Fetch the next digit (0) from the dividend, attach it to 79 and continue: 790 / 879

Advancing to step 3:
879 goes into 790 0 times with a remainder of 790.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 790 to get 790.
Take the next digit (9) from the dividend and append it to 790, then repeat: 7909 / 879

On to step 4:
879 can be fit into 7909 8 times, resulting in a remainder of 877.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we subtract 7032 from 7909, we get 877.
Bring next digit (8) of the dividend behind the 877 and repeat the process: 8778 / 879

Advancing to step 5:
If we divide 8778 by 879, we get 9 and a remainder of 867.
The number 9 becomes the next digit in our result. 
Result so far: 89.0
Subtracting 7911 from 8778 leaves us with 867.
Grab the next digit (7) from the dividend, add it to 867, then carry on: 8677 / 879

Moving on to step 6:
8677 divided by 879 is 9 with a remainder of 766.
Use 9 as the next digit of our solution. 
Result so far: 899.0
If we subtract 7911 from 8677, we get 766.
Include the next digit (5) from the dividend after 766, then repeat: 7665 / 879

Advancing to step 7:
When dividing 7665 by 879, we get 8 with a remainder of 633.
Write down 8 as next digit of the result. 
Result so far: 8998.0
Deduct 7032 from 7665 and we're left with 633.
Bring next digit (9) of the dividend behind the 633 and repeat the process: 6339 / 879

Step 8:
879 can be fit into 6339 7 times, resulting in a remainder of 186.
Put 7 as the next digit of the answer. 
Result so far: 89987.0
Deduct 6153 from 6339 and we're left with 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Going ahead to step 9:
When dividing 1860 by 879, we get 2 with a remainder of 102.
Record the quotient 2 as the next digit in the result. 
Result so far: 89987.2
Deduct 1758 from 1860 and we're left with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Step 10:
The number 879 fits into 1020 1 times, leaving a remainder of 141.
Write down 1 as next digit of the result. 
Result so far: 89987.21
Subtracting 879 from 1020 leaves us with 141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

Going ahead to step 11:
1410 divided by 879 is 1 with a remainder of 531.
The number 1 becomes the next digit in our result. 
Result so far: 89987.211
The remainder is 531 after subtracting 879 from 1410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5310, and continue the process.

After the division, we end up with 89987.211 and a remainder of 0.0531.
