We divide 72905863 by 520
We want to divide 72905863 by 520.

Advancing to step 1:
If we divide 7 by 520, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 520

Going ahead to step 2:
72 divided by 520 is 0 with a remainder of 72.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 72 to get 72.
Append the next digit (9) from the dividend to 72 and continue with: 729 / 520

Advancing to step 3:
729 divided by 520 is 1 with a remainder of 209.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 520 from 729 leaves us with 209.
Append the next digit (0) from the dividend to 209 and continue with: 2090 / 520

Step 4:
520 can be fit into 2090 4 times, resulting in a remainder of 10.
Put 4 as the next digit of the answer. 
Result so far: 14.0
Subtracting 2080 from 2090 leaves us with 10.
Include the next digit (5) from the dividend after 10, then repeat: 105 / 520

Advancing to step 5:
When dividing 105 by 520, we get 0 with a remainder of 105.
The number 0 becomes the next digit in our result. 
Result so far: 140.0
Subtracting 0 from 105 leaves us with 105.
Include the next digit (8) from the dividend after 105, then repeat: 1058 / 520

Moving on to step 6:
If we divide 1058 by 520, we get 2 and a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 1402.0
Subtracting 1040 from 1058 leaves us with 18.
Take the next digit (6) from the dividend and append it to 18, then repeat: 186 / 520

On to step 7:
186 divided by 520 is 0 with a remainder of 186.
Use 0 as the next digit of our solution. 
Result so far: 14020.0
The remainder is 186 after subtracting 0 from 186.
Append the next digit (3) from the dividend to 186 and continue with: 1863 / 520

Step 8:
520 goes into 1863 3 times with a remainder of 303.
Record the quotient 3 as the next digit in the result. 
Result so far: 140203.0
Subtract 1560 from 1863 to get 303.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3030, and continue the process.

Advancing to step 9:
If we divide 3030 by 520, we get 5 and a remainder of 430.
The next digit of our result is 5. 
Result so far: 140203.5
Subtracting 2600 from 3030 leaves us 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.
Write down 8 as next digit of the result. 
Result so far: 140203.58
Deduct 4160 from 4300 and we're left 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.

Step 11:
520 goes into 1400 2 times with a remainder of 360.
The number 2 becomes the next digit in our result. 
Result so far: 140203.582
If we subtract 1040 from 1400, we get 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:
If we divide 3600 by 520, we get 6 and a remainder of 480.
Record the quotient 6 as the next digit in the result. 
Result so far: 140203.5826
Subtract 3120 from 3600 to 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.

Advancing to step 13:
If we divide 4800 by 520, we get 9 and a remainder of 120.
Put 9 as the next digit of the answer. 
Result so far: 140203.58269
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 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: 140203.582692
Subtracting 1040 from 1200 leaves us 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.

Advancing to step 15:
The number 520 fits into 1600 3 times, leaving a remainder of 40.
Write down 3 as next digit of the result. 
Result so far: 140203.5826923
The remainder is 40 after subtracting 1560 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 16:
520 can be fit into 400 0 times, resulting in a remainder of 400.
The next digit of our result is 0. 
Result so far: 140203.5826923
Subtracting 0 from 400 leaves us 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 140203.5826923, and the remainder is 4e-07.
