We look at the division of 90106737 by 80 
We want to figure out the number of times 90106737 can be divided by 80.

On to step 1:
When dividing 9 by 80, we get 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 80

Moving on to step 2:
The number 80 fits into 90 1 times, leaving a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 80 from 90, we get 10.
Bring next digit (1) of the dividend behind the 10 and repeat the process: 101 / 80

On to step 3:
The number 80 fits into 101 1 times, leaving a remainder of 21.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Deduct 80 from 101 and we're left with 21.
Include the next digit (0) from the dividend after 21, then repeat: 210 / 80

On to step 4:
The number 80 fits into 210 2 times, leaving a remainder of 50.
Write down 2 as next digit of the result. 
Result so far: 112.0
If we subtract 160 from 210, we get 50.
Grab the next digit (6) from the dividend, add it to 50, then carry on: 506 / 80

Let's proceed to step 5:
80 goes into 506 6 times with a remainder of 26.
The number 6 becomes the next digit in our result. 
Result so far: 1126.0
Subtract 480 from 506 to get 26.
Fetch the next digit (7) from the dividend, attach it to 26 and continue: 267 / 80

Moving on to step 6:
When dividing 267 by 80, we get 3 with a remainder of 27.
Record the quotient 3 as the next digit in the result. 
Result so far: 11263.0
The remainder is 27 after subtracting 240 from 267.
Take the next digit (3) from the dividend and append it to 27, then repeat: 273 / 80

Let's proceed to step 7:
The number 80 fits into 273 3 times, leaving a remainder of 33.
Write down 3 as next digit of the result. 
Result so far: 112633.0
Subtract 240 from 273 to get 33.
Include the next digit (7) from the dividend after 33, then repeat: 337 / 80

Advancing to step 8:
The number 80 fits into 337 4 times, leaving a remainder of 17.
Write down 4 as next digit of the result. 
Result so far: 1126334.0
The remainder is 17 after subtracting 320 from 337.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 9:
80 goes into 170 2 times with a remainder of 10.
Write down 2 as next digit of the result. 
Result so far: 1126334.2
The remainder is 10 after subtracting 160 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 10:
The number 80 fits into 100 1 times, leaving a remainder of 20.
Record the quotient 1 as the next digit in the result. 
Result so far: 1126334.21
Subtracting 80 from 100 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.

Advancing to step 11:
The number 80 fits into 200 2 times, leaving a remainder of 40.
The number 2 becomes the next digit in our result. 
Result so far: 1126334.212
Subtract 160 from 200 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.

Going ahead to step 12:
80 goes into 400 5 times with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 1126334.2125
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.

Let's proceed to step 13:
0 divided by 80 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 1126334.2125
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 14:
0 divided by 80 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 1126334.2125
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.

Our division results in 1126334.2125 with a remaining 0.0.
