Let's divide 75759021 by 505
We want to figure out the number of times 75759021 can be divided by 505.

Step 1:
The number 505 fits into 7 0 times, leaving a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (5) from the dividend, attach it to 7 and continue: 75 / 505

On to step 2:
505 goes into 75 0 times with a remainder of 75.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 75 after subtracting 0 from 75.
Grab the next digit (7) from the dividend, add it to 75, then carry on: 757 / 505

Moving on to step 3:
505 goes into 757 1 times with a remainder of 252.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 505 from 757 leaves us with 252.
Bring next digit (5) of the dividend behind the 252 and repeat the process: 2525 / 505

Step 4:
2525 divided by 505 is 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Deduct 2525 from 2525 and we're left with 0.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 505

Step 5:
505 can be fit into 9 0 times, resulting in a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 150.0
Subtract 0 from 9 to get 9.
Bring next digit (0) of the dividend behind the 9 and repeat the process: 90 / 505

On to step 6:
505 goes into 90 0 times with a remainder of 90.
The next digit of our result is 0. 
Result so far: 1500.0
Subtract 0 from 90 to get 90.
Append the next digit (2) from the dividend to 90 and continue with: 902 / 505

On to step 7:
When dividing 902 by 505, we get 1 with a remainder of 397.
The number 1 becomes the next digit in our result. 
Result so far: 15001.0
Deduct 505 from 902 and we're left with 397.
Include the next digit (1) from the dividend after 397, then repeat: 3971 / 505

Step 8:
505 goes into 3971 7 times with a remainder of 436.
The number 7 becomes the next digit in our result. 
Result so far: 150017.0
Subtracting 3535 from 3971 leaves us with 436.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4360, and continue the process.

Moving on to step 9:
When dividing 4360 by 505, we get 8 with a remainder of 320.
Record the quotient 8 as the next digit in the result. 
Result so far: 150017.8
Subtract 4040 from 4360 to get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

On to step 10:
If we divide 3200 by 505, we get 6 and a remainder of 170.
Use 6 as the next digit of our solution. 
Result so far: 150017.86
Deduct 3030 from 3200 and we're left with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Advancing to step 11:
When dividing 1700 by 505, we get 3 with a remainder of 185.
Put 3 as the next digit of the answer. 
Result so far: 150017.863
Subtract 1515 from 1700 to get 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Going ahead to step 12:
505 goes into 1850 3 times with a remainder of 335.
Record the quotient 3 as the next digit in the result. 
Result so far: 150017.8633
Deduct 1515 from 1850 and we're left with 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

In conclusion, the division gives 150017.8633 with a balance of 0.00335.
