We divide 307984 by 86
Our goal is to divide 307984 by 86.

On to step 1:
3 divided by 86 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 86

Advancing to step 2:
86 goes into 30 0 times with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 30 after subtracting 0 from 30.
Take the next digit (7) from the dividend and append it to 30, then repeat: 307 / 86

Let's proceed to step 3:
86 can be fit into 307 3 times, resulting in a remainder of 49.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 258 from 307 leaves us with 49.
Take the next digit (9) from the dividend and append it to 49, then repeat: 499 / 86

Going ahead to step 4:
The number 86 fits into 499 5 times, leaving a remainder of 69.
Record the quotient 5 as the next digit in the result. 
Result so far: 35.0
If we take 430 away from 499, we end up with 69.
Bring next digit (8) of the dividend behind the 69 and repeat the process: 698 / 86

Going ahead to step 5:
86 can be fit into 698 8 times, resulting in a remainder of 10.
Put 8 as the next digit of the answer. 
Result so far: 358.0
Subtracting 688 from 698 leaves us with 10.
Bring next digit (4) of the dividend behind the 10 and repeat the process: 104 / 86

Let's proceed to step 6:
If we divide 104 by 86, we get 1 and a remainder of 18.
Write down 1 as next digit of the result. 
Result so far: 3581.0
Subtracting 86 from 104 leaves us 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.

Moving on to step 7:
When dividing 180 by 86, we get 2 with a remainder of 8.
The next digit of our result is 2. 
Result so far: 3581.2
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.

Going ahead to step 8:
The number 86 fits into 80 0 times, leaving a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 3581.2
The remainder is 80 after subtracting 0 from 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:
800 divided by 86 is 9 with a remainder of 26.
Put 9 as the next digit of the answer. 
Result so far: 3581.209
Subtract 774 from 800 to 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.

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: 3581.2093
Subtracting 258 from 260 leaves us with 2.
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:
20 divided by 86 is 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 3581.2093
Subtracting 0 from 20 leaves us 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.

Moving on to step 12:
The number 86 fits into 200 2 times, leaving a remainder of 28.
The next digit of our result is 2. 
Result so far: 3581.209302
If we subtract 172 from 200, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 13:
The number 86 fits into 280 3 times, leaving a remainder of 22.
Use 3 as the next digit of our solution. 
Result so far: 3581.2093023
Deduct 258 from 280 and we're left 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.
Write down 2 as next digit of the result. 
Result so far: 3581.20930232
Subtracting 172 from 220 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

After the division, we end up with 3581.20930232 and a remainder of 4.8e-08.
