12819031 ÷ 520 
Let's see how many times 520 fits into 12819031.

Going ahead to step 1:
If we divide 1 by 520, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 520

Step 2:
When dividing 12 by 520, we get 0 with a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Fetch the next digit (8) from the dividend, attach it to 12 and continue: 128 / 520

Moving on to step 3:
128 divided by 520 is 0 with a remainder of 128.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 128 leaves us with 128.
Bring next digit (1) of the dividend behind the 128 and repeat the process: 1281 / 520

Moving on to step 4:
520 goes into 1281 2 times with a remainder of 241.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 1040 from 1281 leaves us with 241.
Include the next digit (9) from the dividend after 241, then repeat: 2419 / 520

Step 5:
2419 divided by 520 is 4 with a remainder of 339.
Record the quotient 4 as the next digit in the result. 
Result so far: 24.0
The remainder is 339 after subtracting 2080 from 2419.
Include the next digit (0) from the dividend after 339, then repeat: 3390 / 520

Advancing to step 6:
3390 divided by 520 is 6 with a remainder of 270.
Use 6 as the next digit of our solution. 
Result so far: 246.0
Subtract 3120 from 3390 to get 270.
Take the next digit (3) from the dividend and append it to 270, then repeat: 2703 / 520

Let's proceed to step 7:
If we divide 2703 by 520, we get 5 and a remainder of 103.
Write down 5 as next digit of the result. 
Result so far: 2465.0
If we take 2600 away from 2703, we end up with 103.
Fetch the next digit (1) from the dividend, attach it to 103 and continue: 1031 / 520

On to step 8:
520 can be fit into 1031 1 times, resulting in a remainder of 511.
The number 1 becomes the next digit in our result. 
Result so far: 24651.0
The remainder is 511 after subtracting 520 from 1031.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5110, and continue the process.

Moving on to step 9:
When dividing 5110 by 520, we get 9 with a remainder of 430.
Use 9 as the next digit of our solution. 
Result so far: 24651.9
Deduct 4680 from 5110 and we're left with 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Moving on to step 10:
520 goes into 4300 8 times with a remainder of 140.
Use 8 as the next digit of our solution. 
Result so far: 24651.98
If we take 4160 away from 4300, we end up with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Advancing to step 11:
If we divide 1400 by 520, we get 2 and a remainder of 360.
Put 2 as the next digit of the answer. 
Result so far: 24651.982
If we take 1040 away from 1400, we end up with 360.
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 12:
520 can be fit into 3600 6 times, resulting in a remainder of 480.
The number 6 becomes the next digit in our result. 
Result so far: 24651.9826
If we subtract 3120 from 3600, we get 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Going ahead to step 13:
When dividing 4800 by 520, we get 9 with a remainder of 120.
Write down 9 as next digit of the result. 
Result so far: 24651.98269
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.

Step 14:
1200 divided by 520 is 2 with a remainder of 160.
The number 2 becomes the next digit in our result. 
Result so far: 24651.982692
If we take 1040 away from 1200, we end up 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.

Step 15:
If we divide 1600 by 520, we get 3 and a remainder of 40.
The number 3 becomes the next digit in our result. 
Result so far: 24651.9826923
Deduct 1560 from 1600 and we're left 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.

Moving on to step 16:
520 can be fit into 400 0 times, resulting in a remainder of 400.
Record the quotient 0 as the next digit in the result. 
Result so far: 24651.9826923
If we take 0 away from 400, we end up 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.

The quotient of the division is 24651.9826923, and the remainder is 4e-07.
