99319634 ÷ 79 
Our goal is to divide 99319634 by 79.

Advancing to step 1:
When dividing 9 by 79, we get 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 79

Going ahead to step 2:
If we divide 99 by 79, we get 1 and a remainder of 20.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 20 after subtracting 79 from 99.
Fetch the next digit (3) from the dividend, attach it to 20 and continue: 203 / 79

Advancing to step 3:
When dividing 203 by 79, we get 2 with a remainder of 45.
Use 2 as the next digit of our solution. 
Result so far: 12.0
If we subtract 158 from 203, we get 45.
Take the next digit (1) from the dividend and append it to 45, then repeat: 451 / 79

Going ahead to step 4:
79 goes into 451 5 times with a remainder of 56.
Record the quotient 5 as the next digit in the result. 
Result so far: 125.0
Deduct 395 from 451 and we're left with 56.
Append the next digit (9) from the dividend to 56 and continue with: 569 / 79

On to step 5:
79 can be fit into 569 7 times, resulting in a remainder of 16.
Write down 7 as next digit of the result. 
Result so far: 1257.0
If we take 553 away from 569, we end up with 16.
Take the next digit (6) from the dividend and append it to 16, then repeat: 166 / 79

Moving on to step 6:
79 goes into 166 2 times with a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 12572.0
Subtract 158 from 166 to get 8.
Bring next digit (3) of the dividend behind the 8 and repeat the process: 83 / 79

Step 7:
79 goes into 83 1 times with a remainder of 4.
Write down 1 as next digit of the result. 
Result so far: 125721.0
Deduct 79 from 83 and we're left with 4.
Fetch the next digit (4) from the dividend, attach it to 4 and continue: 44 / 79

Let's proceed to step 8:
79 goes into 44 0 times with a remainder of 44.
Put 0 as the next digit of the answer. 
Result so far: 1257210.0
Subtracting 0 from 44 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 9:
If we divide 440 by 79, we get 5 and a remainder of 45.
The number 5 becomes the next digit in our result. 
Result so far: 1257210.5
Deduct 395 from 440 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 10:
450 divided by 79 is 5 with a remainder of 55.
The next digit of our result is 5. 
Result so far: 1257210.55
The remainder is 55 after subtracting 395 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

The final outcome is 1257210.55, with a leftover of 0.055.
