Let's divide 97948777 by 80
Our goal is to divide 97948777 by 80.

Moving on to step 1:
If we divide 9 by 80, we get 0 and a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Append the next digit (7) from the dividend to 9 and continue with: 97 / 80

Going ahead to step 2:
If we divide 97 by 80, we get 1 and a remainder of 17.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 80 away from 97, we end up with 17.
Bring next digit (9) of the dividend behind the 17 and repeat the process: 179 / 80

Moving on to step 3:
179 divided by 80 is 2 with a remainder of 19.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Subtract 160 from 179 to get 19.
Take the next digit (4) from the dividend and append it to 19, then repeat: 194 / 80

Advancing to step 4:
194 divided by 80 is 2 with a remainder of 34.
Record the quotient 2 as the next digit in the result. 
Result so far: 122.0
Subtracting 160 from 194 leaves us with 34.
Include the next digit (8) from the dividend after 34, then repeat: 348 / 80

Going ahead to step 5:
348 divided by 80 is 4 with a remainder of 28.
The number 4 becomes the next digit in our result. 
Result so far: 1224.0
Deduct 320 from 348 and we're left with 28.
Fetch the next digit (7) from the dividend, attach it to 28 and continue: 287 / 80

Step 6:
80 can be fit into 287 3 times, resulting in a remainder of 47.
Write down 3 as next digit of the result. 
Result so far: 12243.0
The remainder is 47 after subtracting 240 from 287.
Fetch the next digit (7) from the dividend, attach it to 47 and continue: 477 / 80

Advancing to step 7:
80 can be fit into 477 5 times, resulting in a remainder of 77.
The number 5 becomes the next digit in our result. 
Result so far: 122435.0
Deduct 400 from 477 and we're left with 77.
Include the next digit (7) from the dividend after 77, then repeat: 777 / 80

Going ahead to step 8:
80 can be fit into 777 9 times, resulting in a remainder of 57.
Write down 9 as next digit of the result. 
Result so far: 1224359.0
Deduct 720 from 777 and we're left with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Moving on to step 9:
80 can be fit into 570 7 times, resulting in a remainder of 10.
Write down 7 as next digit of the result. 
Result so far: 1224359.7
Subtracting 560 from 570 leaves us 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.

On to step 10:
If we divide 100 by 80, we get 1 and a remainder of 20.
Record the quotient 1 as the next digit in the result. 
Result so far: 1224359.71
The remainder is 20 after subtracting 80 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 11:
200 divided by 80 is 2 with a remainder of 40.
Record the quotient 2 as the next digit in the result. 
Result so far: 1224359.712
If we take 160 away from 200, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 12:
The number 80 fits into 400 5 times, leaving a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 1224359.7125
If we take 400 away from 400, we end up 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 13:
When dividing 0 by 80, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 1224359.7125
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.

Let's proceed to step 14:
The number 80 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 1224359.7125
If we subtract 0 from 0, we 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 1224359.7125, and the remainder is 0.0.
