We're dividing 86149511 by 239 
Our goal is to divide 86149511 by 239.

Let's proceed to step 1:
If we divide 8 by 239, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 239

Advancing to step 2:
239 goes into 86 0 times with a remainder of 86.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 86 leaves us with 86.
Take the next digit (1) from the dividend and append it to 86, then repeat: 861 / 239

On to step 3:
The number 239 fits into 861 3 times, leaving a remainder of 144.
The next digit of our result is 3. 
Result so far: 3.0
The remainder is 144 after subtracting 717 from 861.
Append the next digit (4) from the dividend to 144 and continue with: 1444 / 239

Step 4:
239 goes into 1444 6 times with a remainder of 10.
The number 6 becomes the next digit in our result. 
Result so far: 36.0
Subtract 1434 from 1444 to get 10.
Grab the next digit (9) from the dividend, add it to 10, then carry on: 109 / 239

On to step 5:
The number 239 fits into 109 0 times, leaving a remainder of 109.
Record the quotient 0 as the next digit in the result. 
Result so far: 360.0
Deduct 0 from 109 and we're left with 109.
Grab the next digit (5) from the dividend, add it to 109, then carry on: 1095 / 239

Moving on to step 6:
If we divide 1095 by 239, we get 4 and a remainder of 139.
The next digit of our result is 4. 
Result so far: 3604.0
Deduct 956 from 1095 and we're left with 139.
Grab the next digit (1) from the dividend, add it to 139, then carry on: 1391 / 239

Going ahead to step 7:
239 can be fit into 1391 5 times, resulting in a remainder of 196.
The number 5 becomes the next digit in our result. 
Result so far: 36045.0
If we take 1195 away from 1391, we end up with 196.
Include the next digit (1) from the dividend after 196, then repeat: 1961 / 239

On to step 8:
When dividing 1961 by 239, we get 8 with a remainder of 49.
The number 8 becomes the next digit in our result. 
Result so far: 360458.0
Subtract 1912 from 1961 to get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Moving on to step 9:
If we divide 490 by 239, we get 2 and a remainder of 12.
The next digit of our result is 2. 
Result so far: 360458.2
If we take 478 away from 490, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 10:
When dividing 120 by 239, we get 0 with a remainder of 120.
The number 0 becomes the next digit in our result. 
Result so far: 360458.2
If we subtract 0 from 120, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Moving on to step 11:
The number 239 fits into 1200 5 times, leaving a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 360458.205
Deduct 1195 from 1200 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 12:
50 divided by 239 is 0 with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 360458.205
Deduct 0 from 50 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 13:
If we divide 500 by 239, we get 2 and a remainder of 22.
Record the quotient 2 as the next digit in the result. 
Result so far: 360458.20502
If we subtract 478 from 500, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 14:
239 goes into 220 0 times with a remainder of 220.
Put 0 as the next digit of the answer. 
Result so far: 360458.20502
Subtract 0 from 220 to get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Advancing to step 15:
239 goes into 2200 9 times with a remainder of 49.
Use 9 as the next digit of our solution. 
Result so far: 360458.2050209
Subtract 2151 from 2200 to get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Going ahead to step 16:
When dividing 490 by 239, we get 2 with a remainder of 12.
Use 2 as the next digit of our solution. 
Result so far: 360458.20502092
Subtract 478 from 490 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The quotient of the division is 360458.20502092, and the remainder is 1.2e-08.
