We look at the division of 91079 by 77 
We want to figure out the number of times 91079 can be divided by 77.

Let's proceed to step 1:
77 goes into 9 0 times with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 77

Let's proceed to step 2:
91 divided by 77 is 1 with a remainder of 14.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 77 from 91, we get 14.
Append the next digit (0) from the dividend to 14 and continue with: 140 / 77

Going ahead to step 3:
When dividing 140 by 77, we get 1 with a remainder of 63.
Write down 1 as next digit of the result. 
Result so far: 11.0
Deduct 77 from 140 and we're left with 63.
Take the next digit (7) from the dividend and append it to 63, then repeat: 637 / 77

Step 4:
The number 77 fits into 637 8 times, leaving a remainder of 21.
Write down 8 as next digit of the result. 
Result so far: 118.0
Subtract 616 from 637 to get 21.
Fetch the next digit (9) from the dividend, attach it to 21 and continue: 219 / 77

Going ahead to step 5:
When dividing 219 by 77, we get 2 with a remainder of 65.
The number 2 becomes the next digit in our result. 
Result so far: 1182.0
Deduct 154 from 219 and we're left with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

On to step 6:
77 can be fit into 650 8 times, resulting in a remainder of 34.
The next digit of our result is 8. 
Result so far: 1182.8
Subtracting 616 from 650 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 7:
When dividing 340 by 77, we get 4 with a remainder of 32.
Record the quotient 4 as the next digit in the result. 
Result so far: 1182.84
Subtract 308 from 340 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 8:
The number 77 fits into 320 4 times, leaving a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 1182.844
Subtracting 308 from 320 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final outcome is 1182.844, with a leftover of 0.0012.
