53718135 ÷ 252 
Let's see how many times 252 fits into 53718135.

On to step 1:
252 goes into 5 0 times with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 252

Going ahead to step 2:
If we divide 53 by 252, we get 0 and a remainder of 53.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 53, we get 53.
Take the next digit (7) from the dividend and append it to 53, then repeat: 537 / 252

Going ahead to step 3:
If we divide 537 by 252, we get 2 and a remainder of 33.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 33 after subtracting 504 from 537.
Include the next digit (1) from the dividend after 33, then repeat: 331 / 252

Moving on to step 4:
If we divide 331 by 252, we get 1 and a remainder of 79.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
If we subtract 252 from 331, we get 79.
Include the next digit (8) from the dividend after 79, then repeat: 798 / 252

Advancing to step 5:
798 divided by 252 is 3 with a remainder of 42.
The next digit of our result is 3. 
Result so far: 213.0
If we take 756 away from 798, we end up with 42.
Fetch the next digit (1) from the dividend, attach it to 42 and continue: 421 / 252

Moving on to step 6:
252 can be fit into 421 1 times, resulting in a remainder of 169.
Put 1 as the next digit of the answer. 
Result so far: 2131.0
Subtracting 252 from 421 leaves us with 169.
Take the next digit (3) from the dividend and append it to 169, then repeat: 1693 / 252

On to step 7:
1693 divided by 252 is 6 with a remainder of 181.
Use 6 as the next digit of our solution. 
Result so far: 21316.0
If we take 1512 away from 1693, we end up with 181.
Append the next digit (5) from the dividend to 181 and continue with: 1815 / 252

Step 8:
The number 252 fits into 1815 7 times, leaving a remainder of 51.
The next digit of our result is 7. 
Result so far: 213167.0
Subtracting 1764 from 1815 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.

Advancing to step 9:
252 goes into 510 2 times with a remainder of 6.
The next digit of our result is 2. 
Result so far: 213167.2
The remainder is 6 after subtracting 504 from 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 10:
The number 252 fits into 60 0 times, leaving a remainder of 60.
The next digit of our result is 0. 
Result so far: 213167.2
Subtract 0 from 60 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 11:
600 divided by 252 is 2 with a remainder of 96.
Record the quotient 2 as the next digit in the result. 
Result so far: 213167.202
If we subtract 504 from 600, we get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Moving on to step 12:
252 goes into 960 3 times with a remainder of 204.
Record the quotient 3 as the next digit in the result. 
Result so far: 213167.2023
Deduct 756 from 960 and we're left with 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Step 13:
252 can be fit into 2040 8 times, resulting in a remainder of 24.
Write down 8 as next digit of the result. 
Result so far: 213167.20238
Subtract 2016 from 2040 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 14:
252 goes into 240 0 times with a remainder of 240.
Put 0 as the next digit of the answer. 
Result so far: 213167.20238
Subtracting 0 from 240 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.

On to step 15:
The number 252 fits into 2400 9 times, leaving a remainder of 132.
Use 9 as the next digit of our solution. 
Result so far: 213167.2023809
If we take 2268 away from 2400, we end up with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Step 16:
1320 divided by 252 is 5 with a remainder of 60.
Use 5 as the next digit of our solution. 
Result so far: 213167.20238095
Subtracting 1260 from 1320 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

The final outcome is 213167.20238095, with a leftover of 6e-08.
