42520327 ÷ 475 
Our goal is to divide 42520327 by 475.

Going ahead to step 1:
If we divide 4 by 475, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 475

On to step 2:
475 can be fit into 42 0 times, resulting in a remainder of 42.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 42 to get 42.
Fetch the next digit (5) from the dividend, attach it to 42 and continue: 425 / 475

Moving on to step 3:
When dividing 425 by 475, we get 0 with a remainder of 425.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 425, we get 425.
Append the next digit (2) from the dividend to 425 and continue with: 4252 / 475

On to step 4:
If we divide 4252 by 475, we get 8 and a remainder of 452.
The next digit of our result is 8. 
Result so far: 8.0
Deduct 3800 from 4252 and we're left with 452.
Append the next digit (0) from the dividend to 452 and continue with: 4520 / 475

On to step 5:
475 goes into 4520 9 times with a remainder of 245.
The next digit of our result is 9. 
Result so far: 89.0
Subtracting 4275 from 4520 leaves us with 245.
Fetch the next digit (3) from the dividend, attach it to 245 and continue: 2453 / 475

Going ahead to step 6:
The number 475 fits into 2453 5 times, leaving a remainder of 78.
The next digit of our result is 5. 
Result so far: 895.0
Subtract 2375 from 2453 to get 78.
Include the next digit (2) from the dividend after 78, then repeat: 782 / 475

Moving on to step 7:
The number 475 fits into 782 1 times, leaving a remainder of 307.
Record the quotient 1 as the next digit in the result. 
Result so far: 8951.0
Deduct 475 from 782 and we're left with 307.
Bring next digit (7) of the dividend behind the 307 and repeat the process: 3077 / 475

Going ahead to step 8:
3077 divided by 475 is 6 with a remainder of 227.
Record the quotient 6 as the next digit in the result. 
Result so far: 89516.0
If we take 2850 away from 3077, we end up with 227.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2270, and continue the process.

Moving on to step 9:
475 can be fit into 2270 4 times, resulting in a remainder of 370.
The next digit of our result is 4. 
Result so far: 89516.4
If we subtract 1900 from 2270, we get 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

On to step 10:
475 can be fit into 3700 7 times, resulting in a remainder of 375.
Write down 7 as next digit of the result. 
Result so far: 89516.47
Deduct 3325 from 3700 and we're left with 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Moving on to step 11:
The number 475 fits into 3750 7 times, leaving a remainder of 425.
Put 7 as the next digit of the answer. 
Result so far: 89516.477
If we subtract 3325 from 3750, we get 425.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

The final result is 89516.477 with a remainder of 0.0425.
