We look at the division of 139979 by 79 
We want to divide 139979 by 79.

On to step 1:
79 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 79

Going ahead to step 2:
When dividing 13 by 79, we get 0 with a remainder of 13.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 13 after subtracting 0 from 13.
Fetch the next digit (9) from the dividend, attach it to 13 and continue: 139 / 79

Going ahead to step 3:
When dividing 139 by 79, we get 1 with a remainder of 60.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 79 from 139 leaves us with 60.
Include the next digit (9) from the dividend after 60, then repeat: 609 / 79

Advancing to step 4:
When dividing 609 by 79, we get 7 with a remainder of 56.
Put 7 as the next digit of the answer. 
Result so far: 17.0
If we subtract 553 from 609, we get 56.
Fetch the next digit (7) from the dividend, attach it to 56 and continue: 567 / 79

On to step 5:
The number 79 fits into 567 7 times, leaving a remainder of 14.
Record the quotient 7 as the next digit in the result. 
Result so far: 177.0
Subtract 553 from 567 to get 14.
Grab the next digit (9) from the dividend, add it to 14, then carry on: 149 / 79

Going ahead to step 6:
The number 79 fits into 149 1 times, leaving a remainder of 70.
Write down 1 as next digit of the result. 
Result so far: 1771.0
Subtract 79 from 149 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 7:
If we divide 700 by 79, we get 8 and a remainder of 68.
The number 8 becomes the next digit in our result. 
Result so far: 1771.8
If we take 632 away from 700, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 8:
When dividing 680 by 79, we get 8 with a remainder of 48.
Write down 8 as next digit of the result. 
Result so far: 1771.88
The remainder is 48 after subtracting 632 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

The quotient of the division is 1771.88, and the remainder is 0.048.
