54517086 ÷ 750 
We're looking to find how many times 750 goes into 54517086.

Let's proceed to step 1:
750 goes into 5 0 times with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Bring next digit (4) of the dividend behind the 5 and repeat the process: 54 / 750

Let's proceed to step 2:
The number 750 fits into 54 0 times, leaving a remainder of 54.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 54, we get 54.
Take the next digit (5) from the dividend and append it to 54, then repeat: 545 / 750

On to step 3:
545 divided by 750 is 0 with a remainder of 545.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 545 to get 545.
Grab the next digit (1) from the dividend, add it to 545, then carry on: 5451 / 750

Step 4:
750 can be fit into 5451 7 times, resulting in a remainder of 201.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we take 5250 away from 5451, we end up with 201.
Include the next digit (7) from the dividend after 201, then repeat: 2017 / 750

Advancing to step 5:
The number 750 fits into 2017 2 times, leaving a remainder of 517.
The number 2 becomes the next digit in our result. 
Result so far: 72.0
If we take 1500 away from 2017, we end up with 517.
Append the next digit (0) from the dividend to 517 and continue with: 5170 / 750

Step 6:
5170 divided by 750 is 6 with a remainder of 670.
The number 6 becomes the next digit in our result. 
Result so far: 726.0
If we subtract 4500 from 5170, we get 670.
Append the next digit (8) from the dividend to 670 and continue with: 6708 / 750

On to step 7:
The number 750 fits into 6708 8 times, leaving a remainder of 708.
The next digit of our result is 8. 
Result so far: 7268.0
If we take 6000 away from 6708, we end up with 708.
Include the next digit (6) from the dividend after 708, then repeat: 7086 / 750

Step 8:
If we divide 7086 by 750, we get 9 and a remainder of 336.
Record the quotient 9 as the next digit in the result. 
Result so far: 72689.0
If we subtract 6750 from 7086, we get 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

On to step 9:
The number 750 fits into 3360 4 times, leaving a remainder of 360.
Use 4 as the next digit of our solution. 
Result so far: 72689.4
The remainder is 360 after subtracting 3000 from 3360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Step 10:
When dividing 3600 by 750, we get 4 with a remainder of 600.
The number 4 becomes the next digit in our result. 
Result so far: 72689.44
Deduct 3000 from 3600 and we're left with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

The final outcome is 72689.44, with a leftover of 0.6.
