We look at the division of 50109235 by 521 
We're looking to find how many times 521 goes into 50109235.

Let's proceed to step 1:
521 can be fit into 5 0 times, resulting in a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Include the next digit (0) from the dividend after 5, then repeat: 50 / 521

Moving on to step 2:
521 can be fit into 50 0 times, resulting in a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 50 after subtracting 0 from 50.
Take the next digit (1) from the dividend and append it to 50, then repeat: 501 / 521

Let's proceed to step 3:
501 divided by 521 is 0 with a remainder of 501.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 501 after subtracting 0 from 501.
Fetch the next digit (0) from the dividend, attach it to 501 and continue: 5010 / 521

Moving on to step 4:
521 goes into 5010 9 times with a remainder of 321.
The next digit of our result is 9. 
Result so far: 9.0
If we subtract 4689 from 5010, we get 321.
Append the next digit (9) from the dividend to 321 and continue with: 3219 / 521

On to step 5:
If we divide 3219 by 521, we get 6 and a remainder of 93.
Write down 6 as next digit of the result. 
Result so far: 96.0
Deduct 3126 from 3219 and we're left with 93.
Append the next digit (2) from the dividend to 93 and continue with: 932 / 521

Advancing to step 6:
The number 521 fits into 932 1 times, leaving a remainder of 411.
The number 1 becomes the next digit in our result. 
Result so far: 961.0
Subtracting 521 from 932 leaves us with 411.
Grab the next digit (3) from the dividend, add it to 411, then carry on: 4113 / 521

On to step 7:
521 goes into 4113 7 times with a remainder of 466.
The next digit of our result is 7. 
Result so far: 9617.0
If we subtract 3647 from 4113, we get 466.
Bring next digit (5) of the dividend behind the 466 and repeat the process: 4665 / 521

On to step 8:
If we divide 4665 by 521, we get 8 and a remainder of 497.
Record the quotient 8 as the next digit in the result. 
Result so far: 96178.0
Subtract 4168 from 4665 to get 497.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4970, and continue the process.

Advancing to step 9:
521 can be fit into 4970 9 times, resulting in a remainder of 281.
Write down 9 as next digit of the result. 
Result so far: 96178.9
Subtracting 4689 from 4970 leaves us with 281.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2810, and continue the process.

Advancing to step 10:
521 goes into 2810 5 times with a remainder of 205.
Write down 5 as next digit of the result. 
Result so far: 96178.95
Deduct 2605 from 2810 and we're left with 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

On to step 11:
The number 521 fits into 2050 3 times, leaving a remainder of 487.
Use 3 as the next digit of our solution. 
Result so far: 96178.953
If we subtract 1563 from 2050, we get 487.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4870, and continue the process.

Advancing to step 12:
The number 521 fits into 4870 9 times, leaving a remainder of 181.
Use 9 as the next digit of our solution. 
Result so far: 96178.9539
If we take 4689 away from 4870, we end up with 181.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

Moving on to step 13:
521 goes into 1810 3 times with a remainder of 247.
The next digit of our result is 3. 
Result so far: 96178.95393
The remainder is 247 after subtracting 1563 from 1810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2470, and continue the process.

Going ahead to step 14:
When dividing 2470 by 521, we get 4 with a remainder of 386.
Use 4 as the next digit of our solution. 
Result so far: 96178.953934
If we subtract 2084 from 2470, we get 386.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

Moving on to step 15:
The number 521 fits into 3860 7 times, leaving a remainder of 213.
Put 7 as the next digit of the answer. 
Result so far: 96178.9539347
If we subtract 3647 from 3860, we get 213.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2130, and continue the process.

Step 16:
521 can be fit into 2130 4 times, resulting in a remainder of 46.
Write down 4 as next digit of the result. 
Result so far: 96178.95393474
Subtracting 2084 from 2130 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Our division results in 96178.95393474 with a remaining 4.6e-08.
