We're dividing 31060515 by 520 
We want to divide 31060515 by 520.

On to step 1:
3 divided by 520 is 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 520

Step 2:
If we divide 31 by 520, we get 0 and a remainder of 31.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 31, we get 31.
Include the next digit (0) from the dividend after 31, then repeat: 310 / 520

Going ahead to step 3:
The number 520 fits into 310 0 times, leaving a remainder of 310.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 310 leaves us with 310.
Fetch the next digit (6) from the dividend, attach it to 310 and continue: 3106 / 520

On to step 4:
520 goes into 3106 5 times with a remainder of 506.
The next digit of our result is 5. 
Result so far: 5.0
The remainder is 506 after subtracting 2600 from 3106.
Fetch the next digit (0) from the dividend, attach it to 506 and continue: 5060 / 520

On to step 5:
520 can be fit into 5060 9 times, resulting in a remainder of 380.
Use 9 as the next digit of our solution. 
Result so far: 59.0
If we subtract 4680 from 5060, we get 380.
Append the next digit (5) from the dividend to 380 and continue with: 3805 / 520

Step 6:
When dividing 3805 by 520, we get 7 with a remainder of 165.
The next digit of our result is 7. 
Result so far: 597.0
The remainder is 165 after subtracting 3640 from 3805.
Take the next digit (1) from the dividend and append it to 165, then repeat: 1651 / 520

Advancing to step 7:
When dividing 1651 by 520, we get 3 with a remainder of 91.
The number 3 becomes the next digit in our result. 
Result so far: 5973.0
Subtracting 1560 from 1651 leaves us with 91.
Append the next digit (5) from the dividend to 91 and continue with: 915 / 520

On to step 8:
The number 520 fits into 915 1 times, leaving a remainder of 395.
Put 1 as the next digit of the answer. 
Result so far: 59731.0
The remainder is 395 after subtracting 520 from 915.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3950, and continue the process.

Step 9:
The number 520 fits into 3950 7 times, leaving a remainder of 310.
The number 7 becomes the next digit in our result. 
Result so far: 59731.7
Subtracting 3640 from 3950 leaves us with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Let's proceed to step 10:
When dividing 3100 by 520, we get 5 with a remainder of 500.
Write down 5 as next digit of the result. 
Result so far: 59731.75
Subtract 2600 from 3100 to get 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Step 11:
The number 520 fits into 5000 9 times, leaving a remainder of 320.
Record the quotient 9 as the next digit in the result. 
Result so far: 59731.759
Subtract 4680 from 5000 to get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

On to step 12:
520 can be fit into 3200 6 times, resulting in a remainder of 80.
The next digit of our result is 6. 
Result so far: 59731.7596
If we take 3120 away from 3200, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 13:
If we divide 800 by 520, we get 1 and a remainder of 280.
Put 1 as the next digit of the answer. 
Result so far: 59731.75961
If we subtract 520 from 800, we get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Going ahead to step 14:
The number 520 fits into 2800 5 times, leaving a remainder of 200.
The next digit of our result is 5. 
Result so far: 59731.759615
If we take 2600 away from 2800, we end up with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Going ahead to step 15:
2000 divided by 520 is 3 with a remainder of 440.
The next digit of our result is 3. 
Result so far: 59731.7596153
Subtracting 1560 from 2000 leaves us with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

On to step 16:
The number 520 fits into 4400 8 times, leaving a remainder of 240.
The next digit of our result is 8. 
Result so far: 59731.75961538
Deduct 4160 from 4400 and we're left with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

The quotient of the division is 59731.75961538, and the remainder is 2.4e-07.
