We look at the division of 51816591 by 754 
We want to figure out the number of times 51816591 can be divided by 754.

Going ahead to step 1:
5 divided by 754 is 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 754

Moving on to step 2:
754 goes into 51 0 times with a remainder of 51.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 51, we get 51.
Include the next digit (8) from the dividend after 51, then repeat: 518 / 754

Let's proceed to step 3:
518 divided by 754 is 0 with a remainder of 518.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 518, we end up with 518.
Append the next digit (1) from the dividend to 518 and continue with: 5181 / 754

Going ahead to step 4:
5181 divided by 754 is 6 with a remainder of 657.
Use 6 as the next digit of our solution. 
Result so far: 6.0
If we subtract 4524 from 5181, we get 657.
Fetch the next digit (6) from the dividend, attach it to 657 and continue: 6576 / 754

On to step 5:
754 goes into 6576 8 times with a remainder of 544.
The next digit of our result is 8. 
Result so far: 68.0
If we subtract 6032 from 6576, we get 544.
Append the next digit (5) from the dividend to 544 and continue with: 5445 / 754

On to step 6:
754 can be fit into 5445 7 times, resulting in a remainder of 167.
Write down 7 as next digit of the result. 
Result so far: 687.0
If we subtract 5278 from 5445, we get 167.
Grab the next digit (9) from the dividend, add it to 167, then carry on: 1679 / 754

Going ahead to step 7:
When dividing 1679 by 754, we get 2 with a remainder of 171.
Use 2 as the next digit of our solution. 
Result so far: 6872.0
The remainder is 171 after subtracting 1508 from 1679.
Append the next digit (1) from the dividend to 171 and continue with: 1711 / 754

Step 8:
754 goes into 1711 2 times with a remainder of 203.
Use 2 as the next digit of our solution. 
Result so far: 68722.0
The remainder is 203 after subtracting 1508 from 1711.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2030, and continue the process.

On to step 9:
754 can be fit into 2030 2 times, resulting in a remainder of 522.
The next digit of our result is 2. 
Result so far: 68722.2
Subtract 1508 from 2030 to get 522.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5220, and continue the process.

Going ahead to step 10:
754 goes into 5220 6 times with a remainder of 696.
The next digit of our result is 6. 
Result so far: 68722.26
Deduct 4524 from 5220 and we're left with 696.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6960, and continue the process.

Step 11:
6960 divided by 754 is 9 with a remainder of 174.
Put 9 as the next digit of the answer. 
Result so far: 68722.269
If we take 6786 away from 6960, we end up with 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Going ahead to step 12:
If we divide 1740 by 754, we get 2 and a remainder of 232.
Put 2 as the next digit of the answer. 
Result so far: 68722.2692
Subtract 1508 from 1740 to get 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Going ahead to step 13:
The number 754 fits into 2320 3 times, leaving a remainder of 58.
The next digit of our result is 3. 
Result so far: 68722.26923
Deduct 2262 from 2320 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Going ahead to step 14:
580 divided by 754 is 0 with a remainder of 580.
The next digit of our result is 0. 
Result so far: 68722.26923
The remainder is 580 after subtracting 0 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Going ahead to step 15:
754 goes into 5800 7 times with a remainder of 522.
The next digit of our result is 7. 
Result so far: 68722.2692307
The remainder is 522 after subtracting 5278 from 5800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5220, and continue the process.

Going ahead to step 16:
When dividing 5220 by 754, we get 6 with a remainder of 696.
Write down 6 as next digit of the result. 
Result so far: 68722.26923076
Subtracting 4524 from 5220 leaves us with 696.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6960, and continue the process.

The final result is 68722.26923076 with a remainder of 6.96e-07.
