We're dividing 97740 by 80 
We want to figure out the number of times 97740 can be divided by 80.

Moving on to step 1:
If we divide 9 by 80, we get 0 and a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Grab the next digit (7) from the dividend, add it to 9, then carry on: 97 / 80

Step 2:
97 divided by 80 is 1 with a remainder of 17.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 80 from 97 and we're left with 17.
Grab the next digit (7) from the dividend, add it to 17, then carry on: 177 / 80

On to step 3:
When dividing 177 by 80, we get 2 with a remainder of 17.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Deduct 160 from 177 and we're left with 17.
Bring next digit (4) of the dividend behind the 17 and repeat the process: 174 / 80

Moving on to step 4:
The number 80 fits into 174 2 times, leaving a remainder of 14.
Use 2 as the next digit of our solution. 
Result so far: 122.0
If we take 160 away from 174, we end up with 14.
Append the next digit (0) from the dividend to 14 and continue with: 140 / 80

Moving on to step 5:
140 divided by 80 is 1 with a remainder of 60.
Write down 1 as next digit of the result. 
Result so far: 1221.0
If we take 80 away from 140, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 6:
600 divided by 80 is 7 with a remainder of 40.
The number 7 becomes the next digit in our result. 
Result so far: 1221.7
If we subtract 560 from 600, 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.

Advancing to step 7:
If we divide 400 by 80, we get 5 and a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 1221.75
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 8:
When dividing 0 by 80, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 1221.75
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.

Advancing to step 9:
80 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 1221.75
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.

The final outcome is 1221.75, with a leftover of 0.0.
