Let's divide 90075993 by 520
Let's see how many times 520 fits into 90075993.

Let's proceed to step 1:
520 goes into 9 0 times with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 520

Moving on to step 2:
The number 520 fits into 90 0 times, leaving a remainder of 90.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 90 to get 90.
Grab the next digit (0) from the dividend, add it to 90, then carry on: 900 / 520

Going ahead to step 3:
The number 520 fits into 900 1 times, leaving a remainder of 380.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 520 from 900 to get 380.
Take the next digit (7) from the dividend and append it to 380, then repeat: 3807 / 520

Advancing to step 4:
The number 520 fits into 3807 7 times, leaving a remainder of 167.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
If we take 3640 away from 3807, we end up with 167.
Bring next digit (5) of the dividend behind the 167 and repeat the process: 1675 / 520

Moving on to step 5:
The number 520 fits into 1675 3 times, leaving a remainder of 115.
The next digit of our result is 3. 
Result so far: 173.0
Subtracting 1560 from 1675 leaves us with 115.
Bring next digit (9) of the dividend behind the 115 and repeat the process: 1159 / 520

On to step 6:
1159 divided by 520 is 2 with a remainder of 119.
Put 2 as the next digit of the answer. 
Result so far: 1732.0
If we subtract 1040 from 1159, we get 119.
Append the next digit (9) from the dividend to 119 and continue with: 1199 / 520

Advancing to step 7:
520 goes into 1199 2 times with a remainder of 159.
The next digit of our result is 2. 
Result so far: 17322.0
If we take 1040 away from 1199, we end up with 159.
Fetch the next digit (3) from the dividend, attach it to 159 and continue: 1593 / 520

Let's proceed to step 8:
520 goes into 1593 3 times with a remainder of 33.
The number 3 becomes the next digit in our result. 
Result so far: 173223.0
If we take 1560 away from 1593, we end up with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Let's proceed to step 9:
The number 520 fits into 330 0 times, leaving a remainder of 330.
Put 0 as the next digit of the answer. 
Result so far: 173223.0
Deduct 0 from 330 and we're left with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Advancing to step 10:
520 goes into 3300 6 times with a remainder of 180.
Put 6 as the next digit of the answer. 
Result so far: 173223.06
Subtract 3120 from 3300 to get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Let's proceed to step 11:
1800 divided by 520 is 3 with a remainder of 240.
Write down 3 as next digit of the result. 
Result so far: 173223.063
Subtracting 1560 from 1800 leaves us 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.

Advancing to step 12:
The number 520 fits into 2400 4 times, leaving a remainder of 320.
Use 4 as the next digit of our solution. 
Result so far: 173223.0634
If we take 2080 away from 2400, we end up 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.

Going ahead to step 13:
520 goes into 3200 6 times with a remainder of 80.
Put 6 as the next digit of the answer. 
Result so far: 173223.06346
If we take 3120 away from 3200, we end up 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.

Advancing to step 14:
800 divided by 520 is 1 with a remainder of 280.
The next digit of our result is 1. 
Result so far: 173223.063461
If we take 520 away from 800, we end up 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.

Moving on to step 15:
When dividing 2800 by 520, we get 5 with a remainder of 200.
Write down 5 as next digit of the result. 
Result so far: 173223.0634615
The remainder is 200 after subtracting 2600 from 2800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Going ahead to step 16:
If we divide 2000 by 520, we get 3 and a remainder of 440.
The number 3 becomes the next digit in our result. 
Result so far: 173223.06346153
Subtracting 1560 from 2000 leaves us with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

In conclusion, the division gives 173223.06346153 with a balance of 4.4e-07.
