Let's divide 71231824 by 315
We're looking to find how many times 315 goes into 71231824.

Going ahead to step 1:
315 can be fit into 7 0 times, resulting in a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (1) from the dividend, attach it to 7 and continue: 71 / 315

Moving on to step 2:
When dividing 71 by 315, we get 0 with a remainder of 71.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 71 to get 71.
Append the next digit (2) from the dividend to 71 and continue with: 712 / 315

Going ahead to step 3:
315 goes into 712 2 times with a remainder of 82.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 630 away from 712, we end up with 82.
Bring next digit (3) of the dividend behind the 82 and repeat the process: 823 / 315

Moving on to step 4:
823 divided by 315 is 2 with a remainder of 193.
Write down 2 as next digit of the result. 
Result so far: 22.0
The remainder is 193 after subtracting 630 from 823.
Grab the next digit (1) from the dividend, add it to 193, then carry on: 1931 / 315

On to step 5:
When dividing 1931 by 315, we get 6 with a remainder of 41.
The next digit of our result is 6. 
Result so far: 226.0
Subtract 1890 from 1931 to get 41.
Take the next digit (8) from the dividend and append it to 41, then repeat: 418 / 315

On to step 6:
418 divided by 315 is 1 with a remainder of 103.
Record the quotient 1 as the next digit in the result. 
Result so far: 2261.0
If we take 315 away from 418, we end up with 103.
Bring next digit (2) of the dividend behind the 103 and repeat the process: 1032 / 315

On to step 7:
When dividing 1032 by 315, we get 3 with a remainder of 87.
Use 3 as the next digit of our solution. 
Result so far: 22613.0
If we take 945 away from 1032, we end up with 87.
Include the next digit (4) from the dividend after 87, then repeat: 874 / 315

On to step 8:
315 goes into 874 2 times with a remainder of 244.
The number 2 becomes the next digit in our result. 
Result so far: 226132.0
If we take 630 away from 874, we end up with 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

On to step 9:
315 can be fit into 2440 7 times, resulting in a remainder of 235.
Record the quotient 7 as the next digit in the result. 
Result so far: 226132.7
If we subtract 2205 from 2440, we get 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

Advancing to step 10:
2350 divided by 315 is 7 with a remainder of 145.
The next digit of our result is 7. 
Result so far: 226132.77
If we subtract 2205 from 2350, we get 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

The final result is 226132.77 with a remainder of 0.145.
