We look at the division of 51601218 by 239 
Our goal is to divide 51601218 by 239.

On to step 1:
239 can be fit into 5 0 times, resulting in a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 239

Step 2:
51 divided by 239 is 0 with a remainder of 51.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 51, we end up with 51.
Take the next digit (6) from the dividend and append it to 51, then repeat: 516 / 239

Going ahead to step 3:
516 divided by 239 is 2 with a remainder of 38.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 478 away from 516, we end up with 38.
Include the next digit (0) from the dividend after 38, then repeat: 380 / 239

Advancing to step 4:
If we divide 380 by 239, we get 1 and a remainder of 141.
Write down 1 as next digit of the result. 
Result so far: 21.0
If we take 239 away from 380, we end up with 141.
Bring next digit (1) of the dividend behind the 141 and repeat the process: 1411 / 239

Going ahead to step 5:
The number 239 fits into 1411 5 times, leaving a remainder of 216.
Record the quotient 5 as the next digit in the result. 
Result so far: 215.0
The remainder is 216 after subtracting 1195 from 1411.
Bring next digit (2) of the dividend behind the 216 and repeat the process: 2162 / 239

Step 6:
If we divide 2162 by 239, we get 9 and a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 2159.0
The remainder is 11 after subtracting 2151 from 2162.
Append the next digit (1) from the dividend to 11 and continue with: 111 / 239

Let's proceed to step 7:
239 can be fit into 111 0 times, resulting in a remainder of 111.
Write down 0 as next digit of the result. 
Result so far: 21590.0
Subtract 0 from 111 to get 111.
Append the next digit (8) from the dividend to 111 and continue with: 1118 / 239

Let's proceed to step 8:
The number 239 fits into 1118 4 times, leaving a remainder of 162.
Use 4 as the next digit of our solution. 
Result so far: 215904.0
Deduct 956 from 1118 and we're left 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.

Going ahead to step 9:
239 can be fit into 1620 6 times, resulting in a remainder of 186.
Use 6 as the next digit of our solution. 
Result so far: 215904.6
Subtract 1434 from 1620 to get 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Going ahead to step 10:
If we divide 1860 by 239, we get 7 and a remainder of 187.
Use 7 as the next digit of our solution. 
Result so far: 215904.67
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.

Let's proceed to step 11:
239 can be fit into 1870 7 times, resulting in a remainder of 197.
Use 7 as the next digit of our solution. 
Result so far: 215904.677
Deduct 1673 from 1870 and we're left with 197.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

Our division results in 215904.677 with a remaining 0.0197.
