We divide 12811317 by 520
We want to divide 12811317 by 520.

Step 1:
The number 520 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 520

On to step 2:
If we divide 12 by 520, we get 0 and a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Fetch the next digit (8) from the dividend, attach it to 12 and continue: 128 / 520

Going ahead to step 3:
520 goes into 128 0 times with a remainder of 128.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 128, we get 128.
Grab the next digit (1) from the dividend, add it to 128, then carry on: 1281 / 520

Let's proceed 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
Subtract 1040 from 1281 to get 241.
Append the next digit (1) from the dividend to 241 and continue with: 2411 / 520

Going ahead to step 5:
If we divide 2411 by 520, we get 4 and a remainder of 331.
The number 4 becomes the next digit in our result. 
Result so far: 24.0
If we take 2080 away from 2411, we end up with 331.
Take the next digit (3) from the dividend and append it to 331, then repeat: 3313 / 520

Moving on to step 6:
The number 520 fits into 3313 6 times, leaving a remainder of 193.
Put 6 as the next digit of the answer. 
Result so far: 246.0
Subtracting 3120 from 3313 leaves us with 193.
Fetch the next digit (1) from the dividend, attach it to 193 and continue: 1931 / 520

Going ahead to step 7:
520 can be fit into 1931 3 times, resulting in a remainder of 371.
The next digit of our result is 3. 
Result so far: 2463.0
Subtracting 1560 from 1931 leaves us with 371.
Include the next digit (7) from the dividend after 371, then repeat: 3717 / 520

Going ahead to step 8:
520 can be fit into 3717 7 times, resulting in a remainder of 77.
The next digit of our result is 7. 
Result so far: 24637.0
If we take 3640 away from 3717, we end up with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Let's proceed to step 9:
When dividing 770 by 520, we get 1 with a remainder of 250.
Record the quotient 1 as the next digit in the result. 
Result so far: 24637.1
Deduct 520 from 770 and we're left with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

On to step 10:
The number 520 fits into 2500 4 times, leaving a remainder of 420.
The number 4 becomes the next digit in our result. 
Result so far: 24637.14
If we subtract 2080 from 2500, we get 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Going ahead to step 11:
When dividing 4200 by 520, we get 8 with a remainder of 40.
Record the quotient 8 as the next digit in the result. 
Result so far: 24637.148
If we subtract 4160 from 4200, we 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.

On to step 12:
The number 520 fits into 400 0 times, leaving a remainder of 400.
Record the quotient 0 as the next digit in the result. 
Result so far: 24637.148
Subtract 0 from 400 to get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

On to step 13:
520 goes into 4000 7 times with a remainder of 360.
The number 7 becomes the next digit in our result. 
Result so far: 24637.14807
If we take 3640 away from 4000, 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.

Step 14:
When dividing 3600 by 520, we get 6 with a remainder of 480.
Record the quotient 6 as the next digit in the result. 
Result so far: 24637.148076
The remainder is 480 after subtracting 3120 from 3600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Advancing to step 15:
If we divide 4800 by 520, we get 9 and a remainder of 120.
Use 9 as the next digit of our solution. 
Result so far: 24637.1480769
Deduct 4680 from 4800 and we're left 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.

Advancing to step 16:
The number 520 fits into 1200 2 times, leaving a remainder of 160.
Record the quotient 2 as the next digit in the result. 
Result so far: 24637.14807692
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.

The quotient of the division is 24637.14807692, and the remainder is 1.6e-07.
