We look at the division of 75937524 by 521 
We want to divide 75937524 by 521.

Step 1:
7 divided by 521 is 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (5) of the dividend behind the 7 and repeat the process: 75 / 521

Going ahead to step 2:
When dividing 75 by 521, we get 0 with a remainder of 75.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 75 leaves us with 75.
Include the next digit (9) from the dividend after 75, then repeat: 759 / 521

Step 3:
759 divided by 521 is 1 with a remainder of 238.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 521 from 759, we get 238.
Take the next digit (3) from the dividend and append it to 238, then repeat: 2383 / 521

Advancing to step 4:
The number 521 fits into 2383 4 times, leaving a remainder of 299.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
The remainder is 299 after subtracting 2084 from 2383.
Take the next digit (7) from the dividend and append it to 299, then repeat: 2997 / 521

Step 5:
When dividing 2997 by 521, we get 5 with a remainder of 392.
Put 5 as the next digit of the answer. 
Result so far: 145.0
The remainder is 392 after subtracting 2605 from 2997.
Grab the next digit (5) from the dividend, add it to 392, then carry on: 3925 / 521

Going ahead to step 6:
521 can be fit into 3925 7 times, resulting in a remainder of 278.
The number 7 becomes the next digit in our result. 
Result so far: 1457.0
If we subtract 3647 from 3925, we get 278.
Append the next digit (2) from the dividend to 278 and continue with: 2782 / 521

Moving on to step 7:
The number 521 fits into 2782 5 times, leaving a remainder of 177.
Put 5 as the next digit of the answer. 
Result so far: 14575.0
If we subtract 2605 from 2782, we get 177.
Fetch the next digit (4) from the dividend, attach it to 177 and continue: 1774 / 521

Advancing to step 8:
1774 divided by 521 is 3 with a remainder of 211.
Use 3 as the next digit of our solution. 
Result so far: 145753.0
If we subtract 1563 from 1774, we get 211.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2110, and continue the process.

Let's proceed to step 9:
521 goes into 2110 4 times with a remainder of 26.
The next digit of our result is 4. 
Result so far: 145753.4
The remainder is 26 after subtracting 2084 from 2110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 10:
260 divided by 521 is 0 with a remainder of 260.
Write down 0 as next digit of the result. 
Result so far: 145753.4
If we subtract 0 from 260, we get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Advancing to step 11:
The number 521 fits into 2600 4 times, leaving a remainder of 516.
Write down 4 as next digit of the result. 
Result so far: 145753.404
Deduct 2084 from 2600 and we're left with 516.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5160, and continue the process.

On to step 12:
521 goes into 5160 9 times with a remainder of 471.
The number 9 becomes the next digit in our result. 
Result so far: 145753.4049
Deduct 4689 from 5160 and we're left with 471.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4710, and continue the process.

On to step 13:
521 can be fit into 4710 9 times, resulting in a remainder of 21.
The next digit of our result is 9. 
Result so far: 145753.40499
Deduct 4689 from 4710 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

After the division, we end up with 145753.40499 and a remainder of 2.1e-05.
