We're dividing 12146866 by 239 
We want to divide 12146866 by 239.

On to step 1:
The number 239 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 239

Going ahead to step 2:
If we divide 12 by 239, we get 0 and a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Bring next digit (1) of the dividend behind the 12 and repeat the process: 121 / 239

On to step 3:
239 goes into 121 0 times with a remainder of 121.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 121 leaves us with 121.
Fetch the next digit (4) from the dividend, attach it to 121 and continue: 1214 / 239

Advancing to step 4:
239 goes into 1214 5 times with a remainder of 19.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtracting 1195 from 1214 leaves us with 19.
Append the next digit (6) from the dividend to 19 and continue with: 196 / 239

Let's proceed to step 5:
If we divide 196 by 239, we get 0 and a remainder of 196.
Record the quotient 0 as the next digit in the result. 
Result so far: 50.0
The remainder is 196 after subtracting 0 from 196.
Fetch the next digit (8) from the dividend, attach it to 196 and continue: 1968 / 239

Step 6:
239 goes into 1968 8 times with a remainder of 56.
Put 8 as the next digit of the answer. 
Result so far: 508.0
The remainder is 56 after subtracting 1912 from 1968.
Bring next digit (6) of the dividend behind the 56 and repeat the process: 566 / 239

Step 7:
566 divided by 239 is 2 with a remainder of 88.
Record the quotient 2 as the next digit in the result. 
Result so far: 5082.0
If we take 478 away from 566, we end up with 88.
Bring next digit (6) of the dividend behind the 88 and repeat the process: 886 / 239

Let's proceed to step 8:
If we divide 886 by 239, we get 3 and a remainder of 169.
Use 3 as the next digit of our solution. 
Result so far: 50823.0
If we take 717 away from 886, we end up with 169.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1690, and continue the process.

Let's proceed to step 9:
The number 239 fits into 1690 7 times, leaving a remainder of 17.
Record the quotient 7 as the next digit in the result. 
Result so far: 50823.7
If we subtract 1673 from 1690, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 10:
239 goes into 170 0 times with a remainder of 170.
Use 0 as the next digit of our solution. 
Result so far: 50823.7
If we subtract 0 from 170, we get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Advancing to step 11:
If we divide 1700 by 239, we get 7 and a remainder of 27.
Use 7 as the next digit of our solution. 
Result so far: 50823.707
The remainder is 27 after subtracting 1673 from 1700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 12:
If we divide 270 by 239, we get 1 and a remainder of 31.
The number 1 becomes the next digit in our result. 
Result so far: 50823.7071
The remainder is 31 after subtracting 239 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 13:
239 can be fit into 310 1 times, resulting in a remainder of 71.
Record the quotient 1 as the next digit in the result. 
Result so far: 50823.70711
Subtracting 239 from 310 leaves us with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

After the division, we end up with 50823.70711 and a remainder of 7.1e-05.
