918791 divided by 51 
We want to figure out the number of times 918791 can be divided by 51.

Let's proceed to step 1:
The number 51 fits into 9 0 times, leaving a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 51

Going ahead to step 2:
When dividing 91 by 51, we get 1 with a remainder of 40.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 40 after subtracting 51 from 91.
Append the next digit (8) from the dividend to 40 and continue with: 408 / 51

On to step 3:
When dividing 408 by 51, we get 8 with a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 18.0
Subtract 408 from 408 to get 0.
Grab the next digit (7) from the dividend, add it to 0, then carry on: 7 / 51

Advancing to step 4:
51 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 180.0
Subtract 0 from 7 to get 7.
Fetch the next digit (9) from the dividend, attach it to 7 and continue: 79 / 51

On to step 5:
51 can be fit into 79 1 times, resulting in a remainder of 28.
Write down 1 as next digit of the result. 
Result so far: 1801.0
Subtracting 51 from 79 leaves us with 28.
Bring next digit (1) of the dividend behind the 28 and repeat the process: 281 / 51

Going ahead to step 6:
The number 51 fits into 281 5 times, leaving a remainder of 26.
Write down 5 as next digit of the result. 
Result so far: 18015.0
Deduct 255 from 281 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 7:
260 divided by 51 is 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 18015.5
Subtracting 255 from 260 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 8:
When dividing 50 by 51, we get 0 with a remainder of 50.
The next digit of our result is 0. 
Result so far: 18015.5
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 9:
The number 51 fits into 500 9 times, leaving a remainder of 41.
Record the quotient 9 as the next digit in the result. 
Result so far: 18015.509
If we subtract 459 from 500, we get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

On to step 10:
410 divided by 51 is 8 with a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 18015.5098
The remainder is 2 after subtracting 408 from 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 11:
When dividing 20 by 51, we get 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 18015.5098
Deduct 0 from 20 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.

Advancing to step 12:
The number 51 fits into 200 3 times, leaving a remainder of 47.
Write down 3 as next digit of the result. 
Result so far: 18015.509803
If we take 153 away from 200, we end up with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Step 13:
51 goes into 470 9 times with a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 18015.5098039
If we take 459 away from 470, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 14:
51 can be fit into 110 2 times, resulting in a remainder of 8.
The next digit of our result is 2. 
Result so far: 18015.50980392
If we take 102 away from 110, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final result is 18015.50980392 with a remainder of 8e-09.
