We're dividing 52503510 by 231 
We want to figure out the number of times 52503510 can be divided by 231.

Step 1:
5 divided by 231 is 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 231

On to step 2:
231 goes into 52 0 times with a remainder of 52.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 52 and we're left with 52.
Fetch the next digit (5) from the dividend, attach it to 52 and continue: 525 / 231

Advancing to step 3:
525 divided by 231 is 2 with a remainder of 63.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 462 from 525, we get 63.
Fetch the next digit (0) from the dividend, attach it to 63 and continue: 630 / 231

Step 4:
If we divide 630 by 231, we get 2 and a remainder of 168.
Put 2 as the next digit of the answer. 
Result so far: 22.0
Subtract 462 from 630 to get 168.
Take the next digit (3) from the dividend and append it to 168, then repeat: 1683 / 231

Going ahead to step 5:
When dividing 1683 by 231, we get 7 with a remainder of 66.
The next digit of our result is 7. 
Result so far: 227.0
If we take 1617 away from 1683, we end up with 66.
Append the next digit (5) from the dividend to 66 and continue with: 665 / 231

Going ahead to step 6:
When dividing 665 by 231, we get 2 with a remainder of 203.
The next digit of our result is 2. 
Result so far: 2272.0
Deduct 462 from 665 and we're left with 203.
Fetch the next digit (1) from the dividend, attach it to 203 and continue: 2031 / 231

Going ahead to step 7:
2031 divided by 231 is 8 with a remainder of 183.
Write down 8 as next digit of the result. 
Result so far: 22728.0
If we take 1848 away from 2031, we end up with 183.
Fetch the next digit (0) from the dividend, attach it to 183 and continue: 1830 / 231

Let's proceed to step 8:
1830 divided by 231 is 7 with a remainder of 213.
Use 7 as the next digit of our solution. 
Result so far: 227287.0
Deduct 1617 from 1830 and we're left with 213.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2130, and continue the process.

Going ahead to step 9:
2130 divided by 231 is 9 with a remainder of 51.
Put 9 as the next digit of the answer. 
Result so far: 227287.9
Subtracting 2079 from 2130 leaves us with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Step 10:
510 divided by 231 is 2 with a remainder of 48.
Put 2 as the next digit of the answer. 
Result so far: 227287.92
If we take 462 away from 510, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 11:
231 goes into 480 2 times with a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 227287.922
If we subtract 462 from 480, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

After the division, we end up with 227287.922 and a remainder of 0.0018.
