Let's divide 51936236 by 239
Our goal is to divide 51936236 by 239.

On to step 1:
The number 239 fits into 5 0 times, leaving a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 239

Step 2:
239 goes into 51 0 times with a remainder of 51.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 51, we get 51.
Grab the next digit (9) from the dividend, add it to 51, then carry on: 519 / 239

Let's proceed to step 3:
The number 239 fits into 519 2 times, leaving a remainder of 41.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 478 from 519 to get 41.
Take the next digit (3) from the dividend and append it to 41, then repeat: 413 / 239

On to step 4:
239 can be fit into 413 1 times, resulting in a remainder of 174.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
Deduct 239 from 413 and we're left with 174.
Grab the next digit (6) from the dividend, add it to 174, then carry on: 1746 / 239

Let's proceed to step 5:
The number 239 fits into 1746 7 times, leaving a remainder of 73.
Write down 7 as next digit of the result. 
Result so far: 217.0
Subtracting 1673 from 1746 leaves us with 73.
Fetch the next digit (2) from the dividend, attach it to 73 and continue: 732 / 239

On to step 6:
If we divide 732 by 239, we get 3 and a remainder of 15.
The next digit of our result is 3. 
Result so far: 2173.0
Deduct 717 from 732 and we're left with 15.
Fetch the next digit (3) from the dividend, attach it to 15 and continue: 153 / 239

Moving on to step 7:
When dividing 153 by 239, we get 0 with a remainder of 153.
Use 0 as the next digit of our solution. 
Result so far: 21730.0
Deduct 0 from 153 and we're left with 153.
Append the next digit (6) from the dividend to 153 and continue with: 1536 / 239

Advancing to step 8:
The number 239 fits into 1536 6 times, leaving a remainder of 102.
The number 6 becomes the next digit in our result. 
Result so far: 217306.0
If we subtract 1434 from 1536, we get 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Step 9:
The number 239 fits into 1020 4 times, leaving a remainder of 64.
Put 4 as the next digit of the answer. 
Result so far: 217306.4
The remainder is 64 after subtracting 956 from 1020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 10:
The number 239 fits into 640 2 times, leaving a remainder of 162.
The next digit of our result is 2. 
Result so far: 217306.42
If we take 478 away from 640, we end up with 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Step 11:
When dividing 1620 by 239, we get 6 with a remainder of 186.
Use 6 as the next digit of our solution. 
Result so far: 217306.426
Deduct 1434 from 1620 and we're left with 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Let's proceed to step 12:
239 can be fit into 1860 7 times, resulting in a remainder of 187.
The next digit of our result is 7. 
Result so far: 217306.4267
Subtracting 1673 from 1860 leaves us with 187.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

Advancing to step 13:
The number 239 fits into 1870 7 times, leaving a remainder of 197.
Put 7 as the next digit of the answer. 
Result so far: 217306.42677
Subtract 1673 from 1870 to get 197.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

The final result is 217306.42677 with a remainder of 0.000197.
