We divide 90302355 by 520
Our goal is to divide 90302355 by 520.

Step 1:
When dividing 9 by 520, we get 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 520

Going ahead to step 2:
520 goes into 90 0 times with a remainder of 90.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 90 to get 90.
Take the next digit (3) from the dividend and append it to 90, then repeat: 903 / 520

On to step 3:
520 can be fit into 903 1 times, resulting in a remainder of 383.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 383 after subtracting 520 from 903.
Append the next digit (0) from the dividend to 383 and continue with: 3830 / 520

Step 4:
The number 520 fits into 3830 7 times, leaving a remainder of 190.
The next digit of our result is 7. 
Result so far: 17.0
Subtract 3640 from 3830 to get 190.
Fetch the next digit (2) from the dividend, attach it to 190 and continue: 1902 / 520

Let's proceed to step 5:
1902 divided by 520 is 3 with a remainder of 342.
Use 3 as the next digit of our solution. 
Result so far: 173.0
Subtract 1560 from 1902 to get 342.
Bring next digit (3) of the dividend behind the 342 and repeat the process: 3423 / 520

On to step 6:
The number 520 fits into 3423 6 times, leaving a remainder of 303.
Use 6 as the next digit of our solution. 
Result so far: 1736.0
Deduct 3120 from 3423 and we're left with 303.
Bring next digit (5) of the dividend behind the 303 and repeat the process: 3035 / 520

Step 7:
When dividing 3035 by 520, we get 5 with a remainder of 435.
Put 5 as the next digit of the answer. 
Result so far: 17365.0
Subtracting 2600 from 3035 leaves us with 435.
Fetch the next digit (5) from the dividend, attach it to 435 and continue: 4355 / 520

Step 8:
4355 divided by 520 is 8 with a remainder of 195.
The next digit of our result is 8. 
Result so far: 173658.0
If we take 4160 away from 4355, we end up with 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

On to step 9:
The number 520 fits into 1950 3 times, leaving a remainder of 390.
Put 3 as the next digit of the answer. 
Result so far: 173658.3
If we subtract 1560 from 1950, we get 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

On to step 10:
The number 520 fits into 3900 7 times, leaving a remainder of 260.
Write down 7 as next digit of the result. 
Result so far: 173658.37
If we take 3640 away from 3900, we end up with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Step 11:
When dividing 2600 by 520, we get 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 173658.375
The remainder is 0 after subtracting 2600 from 2600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 12:
0 divided by 520 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 173658.375
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 13:
520 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 173658.375
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 173658.375 with a balance of 0.0.
