64009331 divided by 520 
We want to divide 64009331 by 520.

On to step 1:
520 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 520

Let's proceed to step 2:
520 can be fit into 64 0 times, resulting in a remainder of 64.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 64 after subtracting 0 from 64.
Fetch the next digit (0) from the dividend, attach it to 64 and continue: 640 / 520

Going ahead to step 3:
640 divided by 520 is 1 with a remainder of 120.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 520 from 640 to get 120.
Fetch the next digit (0) from the dividend, attach it to 120 and continue: 1200 / 520

Moving on to step 4:
520 can be fit into 1200 2 times, resulting in a remainder of 160.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Subtracting 1040 from 1200 leaves us with 160.
Append the next digit (9) from the dividend to 160 and continue with: 1609 / 520

On to step 5:
520 goes into 1609 3 times with a remainder of 49.
Record the quotient 3 as the next digit in the result. 
Result so far: 123.0
The remainder is 49 after subtracting 1560 from 1609.
Take the next digit (3) from the dividend and append it to 49, then repeat: 493 / 520

Going ahead to step 6:
If we divide 493 by 520, we get 0 and a remainder of 493.
The next digit of our result is 0. 
Result so far: 1230.0
If we subtract 0 from 493, we get 493.
Grab the next digit (3) from the dividend, add it to 493, then carry on: 4933 / 520

Moving on to step 7:
520 can be fit into 4933 9 times, resulting in a remainder of 253.
Write down 9 as next digit of the result. 
Result so far: 12309.0
Deduct 4680 from 4933 and we're left with 253.
Take the next digit (1) from the dividend and append it to 253, then repeat: 2531 / 520

Step 8:
2531 divided by 520 is 4 with a remainder of 451.
Use 4 as the next digit of our solution. 
Result so far: 123094.0
Subtracting 2080 from 2531 leaves us with 451.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4510, and continue the process.

On to step 9:
520 can be fit into 4510 8 times, resulting in a remainder of 350.
The number 8 becomes the next digit in our result. 
Result so far: 123094.8
If we take 4160 away from 4510, we end up with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Step 10:
520 can be fit into 3500 6 times, resulting in a remainder of 380.
Put 6 as the next digit of the answer. 
Result so far: 123094.86
Subtracting 3120 from 3500 leaves us with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Advancing to step 11:
520 goes into 3800 7 times with a remainder of 160.
The number 7 becomes the next digit in our result. 
Result so far: 123094.867
If we take 3640 away from 3800, we end up 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 12:
If we divide 1600 by 520, we get 3 and a remainder of 40.
Use 3 as the next digit of our solution. 
Result so far: 123094.8673
If we subtract 1560 from 1600, 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 13:
If we divide 400 by 520, we get 0 and a remainder of 400.
The next digit of our result is 0. 
Result so far: 123094.8673
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.

Let's proceed to step 14:
The number 520 fits into 4000 7 times, leaving a remainder of 360.
Write down 7 as next digit of the result. 
Result so far: 123094.867307
Deduct 3640 from 4000 and we're left 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.

On to step 15:
If we divide 3600 by 520, we get 6 and a remainder of 480.
Write down 6 as next digit of the result. 
Result so far: 123094.8673076
Deduct 3120 from 3600 and we're left with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Going ahead to step 16:
The number 520 fits into 4800 9 times, leaving a remainder of 120.
The next digit of our result is 9. 
Result so far: 123094.86730769
Subtract 4680 from 4800 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

In conclusion, the division gives 123094.86730769 with a balance of 1.2e-07.
