Let's divide 53815631 by 239
Let's see how many times 239 fits into 53815631.

Moving on to step 1:
5 divided by 239 is 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 239

Moving on to step 2:
If we divide 53 by 239, we get 0 and a remainder of 53.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 53, we get 53.
Include the next digit (8) from the dividend after 53, then repeat: 538 / 239

Moving on to step 3:
239 can be fit into 538 2 times, resulting in a remainder of 60.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 478 away from 538, we end up with 60.
Bring next digit (1) of the dividend behind the 60 and repeat the process: 601 / 239

Moving on to step 4:
If we divide 601 by 239, we get 2 and a remainder of 123.
Write down 2 as next digit of the result. 
Result so far: 22.0
Subtract 478 from 601 to get 123.
Grab the next digit (5) from the dividend, add it to 123, then carry on: 1235 / 239

Step 5:
1235 divided by 239 is 5 with a remainder of 40.
Put 5 as the next digit of the answer. 
Result so far: 225.0
The remainder is 40 after subtracting 1195 from 1235.
Append the next digit (6) from the dividend to 40 and continue with: 406 / 239

Going ahead to step 6:
239 goes into 406 1 times with a remainder of 167.
The number 1 becomes the next digit in our result. 
Result so far: 2251.0
If we take 239 away from 406, we end up with 167.
Fetch the next digit (3) from the dividend, attach it to 167 and continue: 1673 / 239

Going ahead to step 7:
239 can be fit into 1673 7 times, resulting in a remainder of 0.
Record the quotient 7 as the next digit in the result. 
Result so far: 22517.0
If we take 1673 away from 1673, we end up with 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 239

On to step 8:
1 divided by 239 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 225170.0
If we subtract 0 from 1, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 9:
If we divide 10 by 239, we get 0 and a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 225170.0
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 10:
The number 239 fits into 100 0 times, leaving a remainder of 100.
Use 0 as the next digit of our solution. 
Result so far: 225170.0
Subtracting 0 from 100 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

The final result is 225170.0 with a remainder of 0.1.
