86820231 divided by 344 
Our goal is to divide 86820231 by 344.

Let's proceed to step 1:
The number 344 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 344

Going ahead to step 2:
86 divided by 344 is 0 with a remainder of 86.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 86 after subtracting 0 from 86.
Fetch the next digit (8) from the dividend, attach it to 86 and continue: 868 / 344

Advancing to step 3:
344 can be fit into 868 2 times, resulting in a remainder of 180.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 688 away from 868, we end up with 180.
Include the next digit (2) from the dividend after 180, then repeat: 1802 / 344

On to step 4:
The number 344 fits into 1802 5 times, leaving a remainder of 82.
Put 5 as the next digit of the answer. 
Result so far: 25.0
The remainder is 82 after subtracting 1720 from 1802.
Grab the next digit (0) from the dividend, add it to 82, then carry on: 820 / 344

Advancing to step 5:
344 can be fit into 820 2 times, resulting in a remainder of 132.
Write down 2 as next digit of the result. 
Result so far: 252.0
If we take 688 away from 820, we end up with 132.
Take the next digit (2) from the dividend and append it to 132, then repeat: 1322 / 344

Let's proceed to step 6:
344 can be fit into 1322 3 times, resulting in a remainder of 290.
Put 3 as the next digit of the answer. 
Result so far: 2523.0
If we subtract 1032 from 1322, we get 290.
Grab the next digit (3) from the dividend, add it to 290, then carry on: 2903 / 344

Advancing to step 7:
344 goes into 2903 8 times with a remainder of 151.
The number 8 becomes the next digit in our result. 
Result so far: 25238.0
Subtracting 2752 from 2903 leaves us with 151.
Take the next digit (1) from the dividend and append it to 151, then repeat: 1511 / 344

Advancing to step 8:
The number 344 fits into 1511 4 times, leaving a remainder of 135.
Put 4 as the next digit of the answer. 
Result so far: 252384.0
If we subtract 1376 from 1511, we get 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Moving on to step 9:
1350 divided by 344 is 3 with a remainder of 318.
The number 3 becomes the next digit in our result. 
Result so far: 252384.3
Deduct 1032 from 1350 and we're left with 318.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

Going ahead to step 10:
344 can be fit into 3180 9 times, resulting in a remainder of 84.
Write down 9 as next digit of the result. 
Result so far: 252384.39
Subtract 3096 from 3180 to get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Step 11:
When dividing 840 by 344, we get 2 with a remainder of 152.
Record the quotient 2 as the next digit in the result. 
Result so far: 252384.392
If we take 688 away from 840, we end up with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Moving on to step 12:
If we divide 1520 by 344, we get 4 and a remainder of 144.
Use 4 as the next digit of our solution. 
Result so far: 252384.3924
Deduct 1376 from 1520 and we're left with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Step 13:
If we divide 1440 by 344, we get 4 and a remainder of 64.
Record the quotient 4 as the next digit in the result. 
Result so far: 252384.39244
The remainder is 64 after subtracting 1376 from 1440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The final result is 252384.39244 with a remainder of 6.4e-05.
