23566507 ÷ 520 
Our goal is to divide 23566507 by 520.

On to step 1:
The number 520 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 520

Let's proceed to step 2:
520 can be fit into 23 0 times, resulting in a remainder of 23.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 23 and we're left with 23.
Bring next digit (5) of the dividend behind the 23 and repeat the process: 235 / 520

On to step 3:
The number 520 fits into 235 0 times, leaving a remainder of 235.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 235 after subtracting 0 from 235.
Bring next digit (6) of the dividend behind the 235 and repeat the process: 2356 / 520

Going ahead to step 4:
520 can be fit into 2356 4 times, resulting in a remainder of 276.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 2080 from 2356, we get 276.
Fetch the next digit (6) from the dividend, attach it to 276 and continue: 2766 / 520

Moving on to step 5:
The number 520 fits into 2766 5 times, leaving a remainder of 166.
Record the quotient 5 as the next digit in the result. 
Result so far: 45.0
Deduct 2600 from 2766 and we're left with 166.
Append the next digit (5) from the dividend to 166 and continue with: 1665 / 520

On to step 6:
1665 divided by 520 is 3 with a remainder of 105.
Use 3 as the next digit of our solution. 
Result so far: 453.0
Subtract 1560 from 1665 to get 105.
Append the next digit (0) from the dividend to 105 and continue with: 1050 / 520

Let's proceed to step 7:
520 can be fit into 1050 2 times, resulting in a remainder of 10.
Put 2 as the next digit of the answer. 
Result so far: 4532.0
If we take 1040 away from 1050, we end up with 10.
Take the next digit (7) from the dividend and append it to 10, then repeat: 107 / 520

On to step 8:
If we divide 107 by 520, we get 0 and a remainder of 107.
Write down 0 as next digit of the result. 
Result so far: 45320.0
If we take 0 away from 107, we end up with 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

Going ahead to step 9:
When dividing 1070 by 520, we get 2 with a remainder of 30.
The number 2 becomes the next digit in our result. 
Result so far: 45320.2
The remainder is 30 after subtracting 1040 from 1070.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 10:
The number 520 fits into 300 0 times, leaving a remainder of 300.
The next digit of our result is 0. 
Result so far: 45320.2
Deduct 0 from 300 and we're left with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Going ahead to step 11:
520 can be fit into 3000 5 times, resulting in a remainder of 400.
Write down 5 as next digit of the result. 
Result so far: 45320.205
Subtracting 2600 from 3000 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.

Going ahead to step 12:
520 goes into 4000 7 times with a remainder of 360.
Put 7 as the next digit of the answer. 
Result so far: 45320.2057
Subtract 3640 from 4000 to get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Advancing to step 13:
520 can be fit into 3600 6 times, resulting in a remainder of 480.
Put 6 as the next digit of the answer. 
Result so far: 45320.20576
Deduct 3120 from 3600 and we're left with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Step 14:
520 can be fit into 4800 9 times, resulting in a remainder of 120.
Write down 9 as next digit of the result. 
Result so far: 45320.205769
If we take 4680 away from 4800, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

On to step 15:
520 goes into 1200 2 times with a remainder of 160.
Record the quotient 2 as the next digit in the result. 
Result so far: 45320.2057692
Deduct 1040 from 1200 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Moving on to step 16:
If we divide 1600 by 520, we get 3 and a remainder of 40.
Use 3 as the next digit of our solution. 
Result so far: 45320.20576923
Subtract 1560 from 1600 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

In conclusion, the division gives 45320.20576923 with a balance of 4e-08.
