We look at the division of 912851 by 80 
We want to figure out the number of times 912851 can be divided by 80.

Step 1:
If we divide 9 by 80, we get 0 and a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 80

Let's proceed to step 2:
80 goes into 91 1 times with a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 80 away from 91, we end up with 11.
Bring next digit (2) of the dividend behind the 11 and repeat the process: 112 / 80

Going ahead to step 3:
The number 80 fits into 112 1 times, leaving a remainder of 32.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Subtracting 80 from 112 leaves us with 32.
Append the next digit (8) from the dividend to 32 and continue with: 328 / 80

Going ahead to step 4:
The number 80 fits into 328 4 times, leaving a remainder of 8.
The next digit of our result is 4. 
Result so far: 114.0
If we subtract 320 from 328, we get 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 80

Moving on to step 5:
The number 80 fits into 85 1 times, leaving a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 1141.0
If we take 80 away from 85, we end up with 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 80

Going ahead to step 6:
The number 80 fits into 51 0 times, leaving a remainder of 51.
Record the quotient 0 as the next digit in the result. 
Result so far: 11410.0
If we take 0 away from 51, we end up with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

On to step 7:
510 divided by 80 is 6 with a remainder of 30.
The next digit of our result is 6. 
Result so far: 11410.6
The remainder is 30 after subtracting 480 from 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 8:
The number 80 fits into 300 3 times, leaving a remainder of 60.
The number 3 becomes the next digit in our result. 
Result so far: 11410.63
Subtract 240 from 300 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 9:
80 goes into 600 7 times with a remainder of 40.
Put 7 as the next digit of the answer. 
Result so far: 11410.637
The remainder is 40 after subtracting 560 from 600.
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.
The next digit of our result is 5. 
Result so far: 11410.6375
If we subtract 400 from 400, 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.

On to step 11:
The number 80 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 11410.6375
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.

Let's proceed to step 12:
80 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 11410.6375
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.

After the division, we end up with 11410.6375 and a remainder of 0.0.
