51504924 ÷ 520 
Our goal is to divide 51504924 by 520.

Advancing to step 1:
When dividing 5 by 520, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 520

Step 2:
520 goes into 51 0 times with a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 51 to get 51.
Fetch the next digit (5) from the dividend, attach it to 51 and continue: 515 / 520

Going ahead to step 3:
The number 520 fits into 515 0 times, leaving a remainder of 515.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 515, we get 515.
Fetch the next digit (0) from the dividend, attach it to 515 and continue: 5150 / 520

On to step 4:
5150 divided by 520 is 9 with a remainder of 470.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtracting 4680 from 5150 leaves us with 470.
Include the next digit (4) from the dividend after 470, then repeat: 4704 / 520

Let's proceed to step 5:
When dividing 4704 by 520, we get 9 with a remainder of 24.
The number 9 becomes the next digit in our result. 
Result so far: 99.0
Subtracting 4680 from 4704 leaves us with 24.
Append the next digit (9) from the dividend to 24 and continue with: 249 / 520

Advancing to step 6:
If we divide 249 by 520, we get 0 and a remainder of 249.
Put 0 as the next digit of the answer. 
Result so far: 990.0
If we subtract 0 from 249, we get 249.
Take the next digit (2) from the dividend and append it to 249, then repeat: 2492 / 520

On to step 7:
520 goes into 2492 4 times with a remainder of 412.
The number 4 becomes the next digit in our result. 
Result so far: 9904.0
If we take 2080 away from 2492, we end up with 412.
Append the next digit (4) from the dividend to 412 and continue with: 4124 / 520

Let's proceed to step 8:
The number 520 fits into 4124 7 times, leaving a remainder of 484.
The number 7 becomes the next digit in our result. 
Result so far: 99047.0
If we take 3640 away from 4124, we end up with 484.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4840, and continue the process.

On to step 9:
520 can be fit into 4840 9 times, resulting in a remainder of 160.
Use 9 as the next digit of our solution. 
Result so far: 99047.9
Subtract 4680 from 4840 to get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Step 10:
1600 divided by 520 is 3 with a remainder of 40.
The next digit of our result is 3. 
Result so far: 99047.93
If we take 1560 away from 1600, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 11:
When dividing 400 by 520, we get 0 with a remainder of 400.
Record the quotient 0 as the next digit in the result. 
Result so far: 99047.93
Deduct 0 from 400 and we're left 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 can be fit into 4000 7 times, resulting in a remainder of 360.
Use 7 as the next digit of our solution. 
Result so far: 99047.9307
The remainder is 360 after subtracting 3640 from 4000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

On to step 13:
If we divide 3600 by 520, we get 6 and a remainder of 480.
The number 6 becomes the next digit in our result. 
Result so far: 99047.93076
If we take 3120 away from 3600, we end up 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.

Moving on to step 14:
520 can be fit into 4800 9 times, resulting in a remainder of 120.
Use 9 as the next digit of our solution. 
Result so far: 99047.930769
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.

Moving on to step 15:
520 can be fit into 1200 2 times, resulting in a remainder of 160.
Put 2 as the next digit of the answer. 
Result so far: 99047.9307692
Subtracting 1040 from 1200 leaves us 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.

Let's proceed to step 16:
1600 divided by 520 is 3 with a remainder of 40.
The number 3 becomes the next digit in our result. 
Result so far: 99047.93076923
If we take 1560 away from 1600, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final outcome is 99047.93076923, with a leftover of 4e-08.
