Let's divide 77930 by 80
We want to divide 77930 by 80.

On to step 1:
When dividing 7 by 80, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 80

Let's proceed to step 2:
When dividing 77 by 80, we get 0 with a remainder of 77.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 77, we get 77.
Bring next digit (9) of the dividend behind the 77 and repeat the process: 779 / 80

Step 3:
80 goes into 779 9 times with a remainder of 59.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
The remainder is 59 after subtracting 720 from 779.
Grab the next digit (3) from the dividend, add it to 59, then carry on: 593 / 80

Let's proceed to step 4:
The number 80 fits into 593 7 times, leaving a remainder of 33.
The number 7 becomes the next digit in our result. 
Result so far: 97.0
The remainder is 33 after subtracting 560 from 593.
Append the next digit (0) from the dividend to 33 and continue with: 330 / 80

Going ahead to step 5:
If we divide 330 by 80, we get 4 and a remainder of 10.
The number 4 becomes the next digit in our result. 
Result so far: 974.0
Deduct 320 from 330 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 6:
80 goes into 100 1 times with a remainder of 20.
The number 1 becomes the next digit in our result. 
Result so far: 974.1
If we take 80 away from 100, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 7:
If we divide 200 by 80, we get 2 and a remainder of 40.
Put 2 as the next digit of the answer. 
Result so far: 974.12
If we subtract 160 from 200, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 8:
If we divide 400 by 80, we get 5 and a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 974.125
Deduct 400 from 400 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 9:
If we divide 0 by 80, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 974.125
Subtracting 0 from 0 leaves us 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.

Going ahead to step 10:
80 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 974.125
Subtracting 0 from 0 leaves us 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.

Our division results in 974.125 with a remaining 0.0.
