We're dividing 23707539 by 521 
We're looking to find how many times 521 goes into 23707539.

Going ahead to step 1:
When dividing 2 by 521, we get 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 521

Let's proceed to step 2:
The number 521 fits into 23 0 times, leaving a remainder of 23.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 23 leaves us with 23.
Fetch the next digit (7) from the dividend, attach it to 23 and continue: 237 / 521

Let's proceed to step 3:
521 can be fit into 237 0 times, resulting in a remainder of 237.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 237 leaves us with 237.
Bring next digit (0) of the dividend behind the 237 and repeat the process: 2370 / 521

Moving on to step 4:
The number 521 fits into 2370 4 times, leaving a remainder of 286.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we subtract 2084 from 2370, we get 286.
Include the next digit (7) from the dividend after 286, then repeat: 2867 / 521

Moving on to step 5:
2867 divided by 521 is 5 with a remainder of 262.
Use 5 as the next digit of our solution. 
Result so far: 45.0
Subtract 2605 from 2867 to get 262.
Append the next digit (5) from the dividend to 262 and continue with: 2625 / 521

Moving on to step 6:
When dividing 2625 by 521, we get 5 with a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 455.0
Subtracting 2605 from 2625 leaves us with 20.
Append the next digit (3) from the dividend to 20 and continue with: 203 / 521

On to step 7:
When dividing 203 by 521, we get 0 with a remainder of 203.
Put 0 as the next digit of the answer. 
Result so far: 4550.0
If we take 0 away from 203, we end up with 203.
Append the next digit (9) from the dividend to 203 and continue with: 2039 / 521

Step 8:
If we divide 2039 by 521, we get 3 and a remainder of 476.
The next digit of our result is 3. 
Result so far: 45503.0
Subtracting 1563 from 2039 leaves us with 476.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

Advancing to step 9:
521 can be fit into 4760 9 times, resulting in a remainder of 71.
Put 9 as the next digit of the answer. 
Result so far: 45503.9
The remainder is 71 after subtracting 4689 from 4760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Moving on to step 10:
When dividing 710 by 521, we get 1 with a remainder of 189.
Put 1 as the next digit of the answer. 
Result so far: 45503.91
Deduct 521 from 710 and we're left with 189.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1890, and continue the process.

Going ahead to step 11:
If we divide 1890 by 521, we get 3 and a remainder of 327.
The number 3 becomes the next digit in our result. 
Result so far: 45503.913
Subtract 1563 from 1890 to get 327.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3270, and continue the process.

Let's proceed to step 12:
3270 divided by 521 is 6 with a remainder of 144.
Use 6 as the next digit of our solution. 
Result so far: 45503.9136
The remainder is 144 after subtracting 3126 from 3270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Advancing to step 13:
521 can be fit into 1440 2 times, resulting in a remainder of 398.
The next digit of our result is 2. 
Result so far: 45503.91362
If we take 1042 away from 1440, we end up with 398.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3980, and continue the process.

Step 14:
If we divide 3980 by 521, we get 7 and a remainder of 333.
Record the quotient 7 as the next digit in the result. 
Result so far: 45503.913627
If we subtract 3647 from 3980, we get 333.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3330, and continue the process.

Advancing to step 15:
3330 divided by 521 is 6 with a remainder of 204.
Use 6 as the next digit of our solution. 
Result so far: 45503.9136276
Deduct 3126 from 3330 and we're left with 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Step 16:
The number 521 fits into 2040 3 times, leaving a remainder of 477.
Use 3 as the next digit of our solution. 
Result so far: 45503.91362763
If we take 1563 away from 2040, we end up with 477.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4770, and continue the process.

After the division, we end up with 45503.91362763 and a remainder of 4.77e-07.
