We're dividing 90512116 by 79 
We want to figure out the number of times 90512116 can be divided by 79.

Step 1:
9 divided by 79 is 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 79

On to step 2:
When dividing 90 by 79, we get 1 with a remainder of 11.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 79 from 90 to get 11.
Append the next digit (5) from the dividend to 11 and continue with: 115 / 79

Advancing to step 3:
79 can be fit into 115 1 times, resulting in a remainder of 36.
Write down 1 as next digit of the result. 
Result so far: 11.0
Deduct 79 from 115 and we're left with 36.
Append the next digit (1) from the dividend to 36 and continue with: 361 / 79

On to step 4:
79 goes into 361 4 times with a remainder of 45.
The number 4 becomes the next digit in our result. 
Result so far: 114.0
Deduct 316 from 361 and we're left with 45.
Take the next digit (2) from the dividend and append it to 45, then repeat: 452 / 79

Going ahead to step 5:
If we divide 452 by 79, we get 5 and a remainder of 57.
The next digit of our result is 5. 
Result so far: 1145.0
Subtract 395 from 452 to get 57.
Append the next digit (1) from the dividend to 57 and continue with: 571 / 79

Going ahead to step 6:
If we divide 571 by 79, we get 7 and a remainder of 18.
Use 7 as the next digit of our solution. 
Result so far: 11457.0
Subtract 553 from 571 to get 18.
Take the next digit (1) from the dividend and append it to 18, then repeat: 181 / 79

Step 7:
79 goes into 181 2 times with a remainder of 23.
Write down 2 as next digit of the result. 
Result so far: 114572.0
If we subtract 158 from 181, we get 23.
Bring next digit (6) of the dividend behind the 23 and repeat the process: 236 / 79

On to step 8:
79 can be fit into 236 2 times, resulting in a remainder of 78.
The next digit of our result is 2. 
Result so far: 1145722.0
The remainder is 78 after subtracting 158 from 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Going ahead to step 9:
79 can be fit into 780 9 times, resulting in a remainder of 69.
Record the quotient 9 as the next digit in the result. 
Result so far: 1145722.9
If we subtract 711 from 780, we get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

On to step 10:
The number 79 fits into 690 8 times, leaving a remainder of 58.
Use 8 as the next digit of our solution. 
Result so far: 1145722.98
Subtract 632 from 690 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 11:
79 can be fit into 580 7 times, resulting in a remainder of 27.
Use 7 as the next digit of our solution. 
Result so far: 1145722.987
The remainder is 27 after subtracting 553 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 12:
79 can be fit into 270 3 times, resulting in a remainder of 33.
Record the quotient 3 as the next digit in the result. 
Result so far: 1145722.9873
The remainder is 33 after subtracting 237 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Moving on to step 13:
The number 79 fits into 330 4 times, leaving a remainder of 14.
Write down 4 as next digit of the result. 
Result so far: 1145722.98734
Deduct 316 from 330 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 14:
If we divide 140 by 79, we get 1 and a remainder of 61.
Put 1 as the next digit of the answer. 
Result so far: 1145722.987341
Deduct 79 from 140 and we're left with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Advancing to step 15:
610 divided by 79 is 7 with a remainder of 57.
Put 7 as the next digit of the answer. 
Result so far: 1145722.9873417
If we subtract 553 from 610, we get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Step 16:
570 divided by 79 is 7 with a remainder of 17.
Write down 7 as next digit of the result. 
Result so far: 1145722.98734177
The remainder is 17 after subtracting 553 from 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

The final result is 1145722.98734177 with a remainder of 1.7e-08.
