We divide 79530 by 20
Our goal is to divide 79530 by 20.

Advancing to step 1:
The number 20 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (9) from the dividend after 7, then repeat: 79 / 20

Going ahead to step 2:
79 divided by 20 is 3 with a remainder of 19.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtract 60 from 79 to get 19.
Bring next digit (5) of the dividend behind the 19 and repeat the process: 195 / 20

Going ahead to step 3:
When dividing 195 by 20, we get 9 with a remainder of 15.
Put 9 as the next digit of the answer. 
Result so far: 39.0
Subtract 180 from 195 to get 15.
Include the next digit (3) from the dividend after 15, then repeat: 153 / 20

On to step 4:
If we divide 153 by 20, we get 7 and a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 397.0
If we subtract 140 from 153, we get 13.
Grab the next digit (0) from the dividend, add it to 13, then carry on: 130 / 20

Step 5:
The number 20 fits into 130 6 times, leaving a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 3976.0
The remainder is 10 after subtracting 120 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 6:
The number 20 fits into 100 5 times, leaving a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 3976.5
Deduct 100 from 100 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 7:
If we divide 0 by 20, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 3976.5
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 3976.5
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 3976.5, and the remainder is 0.0.
