We look at the division of 163145 by 520 
We're looking to find how many times 520 goes into 163145.

Step 1:
If we divide 1 by 520, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 520

Moving on to step 2:
If we divide 16 by 520, we get 0 and a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 16 leaves us with 16.
Bring next digit (3) of the dividend behind the 16 and repeat the process: 163 / 520

Advancing to step 3:
520 can be fit into 163 0 times, resulting in a remainder of 163.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 163 after subtracting 0 from 163.
Grab the next digit (1) from the dividend, add it to 163, then carry on: 1631 / 520

Step 4:
520 can be fit into 1631 3 times, resulting in a remainder of 71.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 71 after subtracting 1560 from 1631.
Include the next digit (4) from the dividend after 71, then repeat: 714 / 520

Moving on to step 5:
520 goes into 714 1 times with a remainder of 194.
The number 1 becomes the next digit in our result. 
Result so far: 31.0
Subtracting 520 from 714 leaves us with 194.
Append the next digit (5) from the dividend to 194 and continue with: 1945 / 520

Going ahead to step 6:
520 can be fit into 1945 3 times, resulting in a remainder of 385.
Put 3 as the next digit of the answer. 
Result so far: 313.0
The remainder is 385 after subtracting 1560 from 1945.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3850, and continue the process.

Going ahead to step 7:
The number 520 fits into 3850 7 times, leaving a remainder of 210.
The next digit of our result is 7. 
Result so far: 313.7
Deduct 3640 from 3850 and we're left with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Going ahead to step 8:
520 goes into 2100 4 times with a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 313.74
If we subtract 2080 from 2100, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 9:
520 can be fit into 200 0 times, resulting in a remainder of 200.
Use 0 as the next digit of our solution. 
Result so far: 313.74
If we take 0 away from 200, 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.

Step 10:
The number 520 fits into 2000 3 times, leaving a remainder of 440.
Write down 3 as next digit of the result. 
Result so far: 313.7403
Subtract 1560 from 2000 to get 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Advancing to step 11:
520 goes into 4400 8 times with a remainder of 240.
Use 8 as the next digit of our solution. 
Result so far: 313.74038
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.

Going ahead to step 12:
If we divide 2400 by 520, we get 4 and a remainder of 320.
The number 4 becomes the next digit in our result. 
Result so far: 313.740384
Subtracting 2080 from 2400 leaves us with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Step 13:
If we divide 3200 by 520, we get 6 and a remainder of 80.
Write down 6 as next digit of the result. 
Result so far: 313.7403846
Subtracting 3120 from 3200 leaves us 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.

Moving on to step 14:
800 divided by 520 is 1 with a remainder of 280.
Write down 1 as next digit of the result. 
Result so far: 313.74038461
Subtracting 520 from 800 leaves us with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

After the division, we end up with 313.74038461 and a remainder of 2.8e-07.
