We're dividing 97179940 by 80 
We want to figure out the number of times 97179940 can be divided by 80.

Going ahead to step 1:
The number 80 fits into 9 0 times, leaving a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Append the next digit (7) from the dividend to 9 and continue with: 97 / 80

Step 2:
97 divided by 80 is 1 with a remainder of 17.
The next digit of our result is 1. 
Result so far: 1.0
If we take 80 away from 97, we end up with 17.
Append the next digit (1) from the dividend to 17 and continue with: 171 / 80

Moving on to step 3:
If we divide 171 by 80, we get 2 and a remainder of 11.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Subtract 160 from 171 to get 11.
Bring next digit (7) of the dividend behind the 11 and repeat the process: 117 / 80

Going ahead to step 4:
80 goes into 117 1 times with a remainder of 37.
Use 1 as the next digit of our solution. 
Result so far: 121.0
Subtract 80 from 117 to get 37.
Grab the next digit (9) from the dividend, add it to 37, then carry on: 379 / 80

Going ahead to step 5:
The number 80 fits into 379 4 times, leaving a remainder of 59.
The next digit of our result is 4. 
Result so far: 1214.0
Subtracting 320 from 379 leaves us with 59.
Bring next digit (9) of the dividend behind the 59 and repeat the process: 599 / 80

Moving on to step 6:
If we divide 599 by 80, we get 7 and a remainder of 39.
Put 7 as the next digit of the answer. 
Result so far: 12147.0
The remainder is 39 after subtracting 560 from 599.
Bring next digit (4) of the dividend behind the 39 and repeat the process: 394 / 80

Let's proceed to step 7:
80 goes into 394 4 times with a remainder of 74.
Put 4 as the next digit of the answer. 
Result so far: 121474.0
Deduct 320 from 394 and we're left with 74.
Append the next digit (0) from the dividend to 74 and continue with: 740 / 80

On to step 8:
If we divide 740 by 80, we get 9 and a remainder of 20.
Write down 9 as next digit of the result. 
Result so far: 1214749.0
Subtracting 720 from 740 leaves us 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.

Step 9:
When dividing 200 by 80, we get 2 with a remainder of 40.
Put 2 as the next digit of the answer. 
Result so far: 1214749.2
The remainder is 40 after subtracting 160 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 10:
400 divided by 80 is 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 1214749.25
The remainder is 0 after subtracting 400 from 400.
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 11:
If we divide 0 by 80, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 1214749.25
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 12:
When dividing 0 by 80, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 1214749.25
If we take 0 away from 0, 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.

In conclusion, the division gives 1214749.25 with a balance of 0.0.
