We're dividing 9901841 by 80 
Our goal is to divide 9901841 by 80.

Moving on to step 1:
80 goes into 9 0 times with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 80

Advancing to step 2:
99 divided by 80 is 1 with a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 80 from 99 and we're left with 19.
Grab the next digit (0) from the dividend, add it to 19, then carry on: 190 / 80

Going ahead to step 3:
80 goes into 190 2 times with a remainder of 30.
Write down 2 as next digit of the result. 
Result so far: 12.0
Subtracting 160 from 190 leaves us with 30.
Take the next digit (1) from the dividend and append it to 30, then repeat: 301 / 80

Step 4:
80 goes into 301 3 times with a remainder of 61.
Use 3 as the next digit of our solution. 
Result so far: 123.0
Deduct 240 from 301 and we're left with 61.
Grab the next digit (8) from the dividend, add it to 61, then carry on: 618 / 80

On to step 5:
The number 80 fits into 618 7 times, leaving a remainder of 58.
Write down 7 as next digit of the result. 
Result so far: 1237.0
Subtract 560 from 618 to get 58.
Fetch the next digit (4) from the dividend, attach it to 58 and continue: 584 / 80

Let's proceed to step 6:
The number 80 fits into 584 7 times, leaving a remainder of 24.
Write down 7 as next digit of the result. 
Result so far: 12377.0
If we subtract 560 from 584, we get 24.
Append the next digit (1) from the dividend to 24 and continue with: 241 / 80

Let's proceed to step 7:
The number 80 fits into 241 3 times, leaving a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 123773.0
Subtract 240 from 241 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 8:
The number 80 fits into 10 0 times, leaving a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 123773.0
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 9:
100 divided by 80 is 1 with a remainder of 20.
Record the quotient 1 as the next digit in the result. 
Result so far: 123773.01
Deduct 80 from 100 and we're left 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.

Let's proceed to step 10:
80 can be fit into 200 2 times, resulting in a remainder of 40.
Put 2 as the next digit of the answer. 
Result so far: 123773.012
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.

Step 11:
80 goes into 400 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 123773.0125
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.

Moving on to step 12:
The number 80 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 123773.0125
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 13:
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: 123773.0125
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.

Our division results in 123773.0125 with a remaining 0.0.
