We look at the division of 75741934 by 517 
We want to figure out the number of times 75741934 can be divided by 517.

Moving on to step 1:
517 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Include the next digit (5) from the dividend after 7, then repeat: 75 / 517

On to step 2:
517 can be fit into 75 0 times, resulting in a remainder of 75.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 75 to get 75.
Take the next digit (7) from the dividend and append it to 75, then repeat: 757 / 517

Moving on to step 3:
757 divided by 517 is 1 with a remainder of 240.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 517 from 757, we get 240.
Bring next digit (4) of the dividend behind the 240 and repeat the process: 2404 / 517

Step 4:
517 can be fit into 2404 4 times, resulting in a remainder of 336.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
Subtracting 2068 from 2404 leaves us with 336.
Include the next digit (1) from the dividend after 336, then repeat: 3361 / 517

Let's proceed to step 5:
517 goes into 3361 6 times with a remainder of 259.
Put 6 as the next digit of the answer. 
Result so far: 146.0
Deduct 3102 from 3361 and we're left with 259.
Fetch the next digit (9) from the dividend, attach it to 259 and continue: 2599 / 517

Let's proceed to step 6:
2599 divided by 517 is 5 with a remainder of 14.
Put 5 as the next digit of the answer. 
Result so far: 1465.0
Subtract 2585 from 2599 to get 14.
Include the next digit (3) from the dividend after 14, then repeat: 143 / 517

Let's proceed to step 7:
When dividing 143 by 517, we get 0 with a remainder of 143.
The number 0 becomes the next digit in our result. 
Result so far: 14650.0
If we take 0 away from 143, we end up with 143.
Bring next digit (4) of the dividend behind the 143 and repeat the process: 1434 / 517

Moving on to step 8:
517 can be fit into 1434 2 times, resulting in a remainder of 400.
The number 2 becomes the next digit in our result. 
Result so far: 146502.0
Subtracting 1034 from 1434 leaves us with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

On to step 9:
If we divide 4000 by 517, we get 7 and a remainder of 381.
Write down 7 as next digit of the result. 
Result so far: 146502.7
If we subtract 3619 from 4000, we get 381.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3810, and continue the process.

Advancing to step 10:
3810 divided by 517 is 7 with a remainder of 191.
Write down 7 as next digit of the result. 
Result so far: 146502.77
If we subtract 3619 from 3810, we get 191.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1910, and continue the process.

After the division, we end up with 146502.77 and a remainder of 0.191.
