71872008 divided by 520 
We want to divide 71872008 by 520.

Moving on to step 1:
7 divided by 520 is 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (1) from the dividend and append it to 7, then repeat: 71 / 520

Going ahead to step 2:
520 can be fit into 71 0 times, resulting in a remainder of 71.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 71 leaves us with 71.
Fetch the next digit (8) from the dividend, attach it to 71 and continue: 718 / 520

Moving on to step 3:
520 goes into 718 1 times with a remainder of 198.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 520 from 718 and we're left with 198.
Include the next digit (7) from the dividend after 198, then repeat: 1987 / 520

Moving on to step 4:
1987 divided by 520 is 3 with a remainder of 427.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
If we take 1560 away from 1987, we end up with 427.
Bring next digit (2) of the dividend behind the 427 and repeat the process: 4272 / 520

On to step 5:
520 can be fit into 4272 8 times, resulting in a remainder of 112.
Use 8 as the next digit of our solution. 
Result so far: 138.0
If we take 4160 away from 4272, we end up with 112.
Include the next digit (0) from the dividend after 112, then repeat: 1120 / 520

Moving on to step 6:
If we divide 1120 by 520, we get 2 and a remainder of 80.
The next digit of our result is 2. 
Result so far: 1382.0
Subtract 1040 from 1120 to get 80.
Append the next digit (0) from the dividend to 80 and continue with: 800 / 520

Advancing to step 7:
When dividing 800 by 520, we get 1 with a remainder of 280.
The number 1 becomes the next digit in our result. 
Result so far: 13821.0
If we take 520 away from 800, we end up with 280.
Append the next digit (8) from the dividend to 280 and continue with: 2808 / 520

Going ahead to step 8:
The number 520 fits into 2808 5 times, leaving a remainder of 208.
Record the quotient 5 as the next digit in the result. 
Result so far: 138215.0
The remainder is 208 after subtracting 2600 from 2808.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Going ahead to step 9:
The number 520 fits into 2080 4 times, leaving a remainder of 0.
The next digit of our result is 4. 
Result so far: 138215.4
If we take 2080 away from 2080, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 10:
If we divide 0 by 520, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 138215.4
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 11:
The number 520 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 138215.4
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 138215.4 and a remainder of 0.0.
