We look at the division of 12162985 by 79 
We want to figure out the number of times 12162985 can be divided by 79.

Step 1:
The number 79 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 79

Advancing to step 2:
12 divided by 79 is 0 with a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Append the next digit (1) from the dividend to 12 and continue with: 121 / 79

Going ahead to step 3:
79 goes into 121 1 times with a remainder of 42.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 42 after subtracting 79 from 121.
Take the next digit (6) from the dividend and append it to 42, then repeat: 426 / 79

Advancing to step 4:
The number 79 fits into 426 5 times, leaving a remainder of 31.
Put 5 as the next digit of the answer. 
Result so far: 15.0
Subtract 395 from 426 to get 31.
Fetch the next digit (2) from the dividend, attach it to 31 and continue: 312 / 79

Moving on to step 5:
79 goes into 312 3 times with a remainder of 75.
Write down 3 as next digit of the result. 
Result so far: 153.0
Subtract 237 from 312 to get 75.
Take the next digit (9) from the dividend and append it to 75, then repeat: 759 / 79

Step 6:
The number 79 fits into 759 9 times, leaving a remainder of 48.
Record the quotient 9 as the next digit in the result. 
Result so far: 1539.0
If we subtract 711 from 759, we get 48.
Fetch the next digit (8) from the dividend, attach it to 48 and continue: 488 / 79

Moving on to step 7:
79 goes into 488 6 times with a remainder of 14.
Use 6 as the next digit of our solution. 
Result so far: 15396.0
If we subtract 474 from 488, we get 14.
Fetch the next digit (5) from the dividend, attach it to 14 and continue: 145 / 79

Step 8:
145 divided by 79 is 1 with a remainder of 66.
Put 1 as the next digit of the answer. 
Result so far: 153961.0
Subtracting 79 from 145 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 9:
If we divide 660 by 79, we get 8 and a remainder of 28.
Put 8 as the next digit of the answer. 
Result so far: 153961.8
If we subtract 632 from 660, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 10:
79 can be fit into 280 3 times, resulting in a remainder of 43.
The next digit of our result is 3. 
Result so far: 153961.83
If we subtract 237 from 280, we get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

On to step 11:
79 can be fit into 430 5 times, resulting in a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 153961.835
If we take 395 away from 430, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 12:
350 divided by 79 is 4 with a remainder of 34.
Put 4 as the next digit of the answer. 
Result so far: 153961.8354
Subtracting 316 from 350 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.

Going ahead to step 13:
If we divide 340 by 79, we get 4 and a remainder of 24.
Write down 4 as next digit of the result. 
Result so far: 153961.83544
If we subtract 316 from 340, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The quotient of the division is 153961.83544, and the remainder is 2.4e-05.
