86213118 ÷ 239 
We want to divide 86213118 by 239.

Step 1:
8 divided by 239 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 239

Let's proceed to step 2:
239 goes into 86 0 times with a remainder of 86.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 86, we get 86.
Fetch the next digit (2) from the dividend, attach it to 86 and continue: 862 / 239

Moving on to step 3:
The number 239 fits into 862 3 times, leaving a remainder of 145.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtract 717 from 862 to get 145.
Include the next digit (1) from the dividend after 145, then repeat: 1451 / 239

Let's proceed to step 4:
239 goes into 1451 6 times with a remainder of 17.
Record the quotient 6 as the next digit in the result. 
Result so far: 36.0
If we take 1434 away from 1451, we end up with 17.
Take the next digit (3) from the dividend and append it to 17, then repeat: 173 / 239

Step 5:
If we divide 173 by 239, we get 0 and a remainder of 173.
The next digit of our result is 0. 
Result so far: 360.0
Subtracting 0 from 173 leaves us with 173.
Include the next digit (1) from the dividend after 173, then repeat: 1731 / 239

On to step 6:
If we divide 1731 by 239, we get 7 and a remainder of 58.
The number 7 becomes the next digit in our result. 
Result so far: 3607.0
The remainder is 58 after subtracting 1673 from 1731.
Bring next digit (1) of the dividend behind the 58 and repeat the process: 581 / 239

Let's proceed to step 7:
239 can be fit into 581 2 times, resulting in a remainder of 103.
Put 2 as the next digit of the answer. 
Result so far: 36072.0
The remainder is 103 after subtracting 478 from 581.
Take the next digit (8) from the dividend and append it to 103, then repeat: 1038 / 239

Advancing to step 8:
When dividing 1038 by 239, we get 4 with a remainder of 82.
The number 4 becomes the next digit in our result. 
Result so far: 360724.0
Subtracting 956 from 1038 leaves us with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Moving on to step 9:
When dividing 820 by 239, we get 3 with a remainder of 103.
Put 3 as the next digit of the answer. 
Result so far: 360724.3
If we take 717 away from 820, we end up with 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

Going ahead to step 10:
239 goes into 1030 4 times with a remainder of 74.
Record the quotient 4 as the next digit in the result. 
Result so far: 360724.34
Subtracting 956 from 1030 leaves us with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Advancing to step 11:
740 divided by 239 is 3 with a remainder of 23.
The number 3 becomes the next digit in our result. 
Result so far: 360724.343
Deduct 717 from 740 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 12:
239 can be fit into 230 0 times, resulting in a remainder of 230.
Use 0 as the next digit of our solution. 
Result so far: 360724.343
Subtracting 0 from 230 leaves us with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Moving on to step 13:
When dividing 2300 by 239, we get 9 with a remainder of 149.
The next digit of our result is 9. 
Result so far: 360724.34309
If we subtract 2151 from 2300, we get 149.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

Going ahead to step 14:
The number 239 fits into 1490 6 times, leaving a remainder of 56.
Use 6 as the next digit of our solution. 
Result so far: 360724.343096
Deduct 1434 from 1490 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 15:
239 goes into 560 2 times with a remainder of 82.
Record the quotient 2 as the next digit in the result. 
Result so far: 360724.3430962
If we subtract 478 from 560, we get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Moving on to step 16:
The number 239 fits into 820 3 times, leaving a remainder of 103.
Use 3 as the next digit of our solution. 
Result so far: 360724.34309623
If we subtract 717 from 820, we get 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

The final outcome is 360724.34309623, with a leftover of 1.03e-07.
