331720 divided by 86 
Let's see how many times 86 fits into 331720.

On to step 1:
86 goes into 3 0 times with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (3) from the dividend after 3, then repeat: 33 / 86

Step 2:
86 goes into 33 0 times with a remainder of 33.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 33, we get 33.
Include the next digit (1) from the dividend after 33, then repeat: 331 / 86

Going ahead to step 3:
86 can be fit into 331 3 times, resulting in a remainder of 73.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we subtract 258 from 331, we get 73.
Append the next digit (7) from the dividend to 73 and continue with: 737 / 86

On to step 4:
86 goes into 737 8 times with a remainder of 49.
Use 8 as the next digit of our solution. 
Result so far: 38.0
Subtract 688 from 737 to get 49.
Take the next digit (2) from the dividend and append it to 49, then repeat: 492 / 86

Let's proceed to step 5:
86 can be fit into 492 5 times, resulting in a remainder of 62.
Write down 5 as next digit of the result. 
Result so far: 385.0
Deduct 430 from 492 and we're left with 62.
Append the next digit (0) from the dividend to 62 and continue with: 620 / 86

Advancing to step 6:
The number 86 fits into 620 7 times, leaving a remainder of 18.
Put 7 as the next digit of the answer. 
Result so far: 3857.0
If we take 602 away from 620, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 7:
86 goes into 180 2 times with a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 3857.2
The remainder is 8 after subtracting 172 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 8:
86 goes into 80 0 times with a remainder of 80.
The next digit of our result is 0. 
Result so far: 3857.2
If we take 0 away from 80, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 9:
86 can be fit into 800 9 times, resulting in a remainder of 26.
The next digit of our result is 9. 
Result so far: 3857.209
If we subtract 774 from 800, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 10:
The number 86 fits into 260 3 times, leaving a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 3857.2093
The remainder is 2 after subtracting 258 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 11:
The number 86 fits into 20 0 times, leaving a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 3857.2093
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 12:
When dividing 200 by 86, we get 2 with a remainder of 28.
The next digit of our result is 2. 
Result so far: 3857.209302
The remainder is 28 after subtracting 172 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 13:
86 can be fit into 280 3 times, resulting in a remainder of 22.
Write down 3 as next digit of the result. 
Result so far: 3857.2093023
Subtracting 258 from 280 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 14:
86 goes into 220 2 times with a remainder of 48.
Use 2 as the next digit of our solution. 
Result so far: 3857.20930232
If we subtract 172 from 220, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Our division results in 3857.20930232 with a remaining 4.8e-08.
