51158088 divided by 239 
We want to divide 51158088 by 239.

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 (1) from the dividend to 5 and continue with: 51 / 239

Step 2:
If we divide 51 by 239, we get 0 and a remainder of 51.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 51 to get 51.
Grab the next digit (1) from the dividend, add it to 51, then carry on: 511 / 239

Going ahead to step 3:
If we divide 511 by 239, we get 2 and a remainder of 33.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 478 from 511 leaves us with 33.
Include the next digit (5) from the dividend after 33, then repeat: 335 / 239

Step 4:
239 can be fit into 335 1 times, resulting in a remainder of 96.
The next digit of our result is 1. 
Result so far: 21.0
If we take 239 away from 335, we end up with 96.
Append the next digit (8) from the dividend to 96 and continue with: 968 / 239

On to step 5:
When dividing 968 by 239, we get 4 with a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 214.0
Subtract 956 from 968 to get 12.
Fetch the next digit (0) from the dividend, attach it to 12 and continue: 120 / 239

Step 6:
The number 239 fits into 120 0 times, leaving a remainder of 120.
Use 0 as the next digit of our solution. 
Result so far: 2140.0
Subtracting 0 from 120 leaves us with 120.
Include the next digit (8) from the dividend after 120, then repeat: 1208 / 239

Advancing to step 7:
239 can be fit into 1208 5 times, resulting in a remainder of 13.
Put 5 as the next digit of the answer. 
Result so far: 21405.0
Subtract 1195 from 1208 to get 13.
Take the next digit (8) from the dividend and append it to 13, then repeat: 138 / 239

Advancing to step 8:
When dividing 138 by 239, we get 0 with a remainder of 138.
Record the quotient 0 as the next digit in the result. 
Result so far: 214050.0
Subtracting 0 from 138 leaves us with 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Step 9:
When dividing 1380 by 239, we get 5 with a remainder of 185.
Write down 5 as next digit of the result. 
Result so far: 214050.5
Subtracting 1195 from 1380 leaves us with 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

On to step 10:
If we divide 1850 by 239, we get 7 and a remainder of 177.
Put 7 as the next digit of the answer. 
Result so far: 214050.57
Subtract 1673 from 1850 to get 177.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1770, and continue the process.

Going ahead to step 11:
239 goes into 1770 7 times with a remainder of 97.
Use 7 as the next digit of our solution. 
Result so far: 214050.577
If we take 1673 away from 1770, we end up with 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

The final outcome is 214050.577, with a leftover of 0.0097.
