Let's divide 97871396 by 80
Our goal is to divide 97871396 by 80.

Going ahead to step 1:
When dividing 9 by 80, we get 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Take the next digit (7) from the dividend and append it to 9, then repeat: 97 / 80

Moving on to step 2:
The number 80 fits into 97 1 times, leaving a remainder of 17.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 80 away from 97, we end up with 17.
Grab the next digit (8) from the dividend, add it to 17, then carry on: 178 / 80

Moving on to step 3:
178 divided by 80 is 2 with a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 12.0
The remainder is 18 after subtracting 160 from 178.
Bring next digit (7) of the dividend behind the 18 and repeat the process: 187 / 80

Going ahead to step 4:
80 goes into 187 2 times with a remainder of 27.
Put 2 as the next digit of the answer. 
Result so far: 122.0
If we subtract 160 from 187, we get 27.
Fetch the next digit (1) from the dividend, attach it to 27 and continue: 271 / 80

Let's proceed to step 5:
The number 80 fits into 271 3 times, leaving a remainder of 31.
The next digit of our result is 3. 
Result so far: 1223.0
If we take 240 away from 271, we end up with 31.
Fetch the next digit (3) from the dividend, attach it to 31 and continue: 313 / 80

Going ahead to step 6:
If we divide 313 by 80, we get 3 and a remainder of 73.
Use 3 as the next digit of our solution. 
Result so far: 12233.0
If we take 240 away from 313, we end up with 73.
Bring next digit (9) of the dividend behind the 73 and repeat the process: 739 / 80

Going ahead to step 7:
If we divide 739 by 80, we get 9 and a remainder of 19.
The number 9 becomes the next digit in our result. 
Result so far: 122339.0
If we subtract 720 from 739, we get 19.
Take the next digit (6) from the dividend and append it to 19, then repeat: 196 / 80

Let's proceed to step 8:
196 divided by 80 is 2 with a remainder of 36.
Record the quotient 2 as the next digit in the result. 
Result so far: 1223392.0
Deduct 160 from 196 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 9:
The number 80 fits into 360 4 times, leaving a remainder of 40.
Record the quotient 4 as the next digit in the result. 
Result so far: 1223392.4
Subtract 320 from 360 to 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.

On to step 10:
80 can be fit into 400 5 times, resulting in a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 1223392.45
Subtracting 400 from 400 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 11:
0 divided by 80 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 1223392.45
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.

Let's proceed to step 12:
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: 1223392.45
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 final outcome is 1223392.45, with a leftover of 0.0.
