307930 divided by 86 
We want to figure out the number of times 307930 can be divided by 86.

Going ahead to step 1:
3 divided by 86 is 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 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.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 30 leaves us with 30.
Include the next digit (7) from the dividend after 30, then repeat: 307 / 86

Let's proceed to step 3:
When dividing 307 by 86, we get 3 with a remainder of 49.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 258 from 307, we get 49.
Append the next digit (9) from the dividend to 49 and continue with: 499 / 86

Step 4:
86 goes into 499 5 times with a remainder of 69.
Put 5 as the next digit of the answer. 
Result so far: 35.0
Deduct 430 from 499 and we're left with 69.
Append the next digit (3) from the dividend to 69 and continue with: 693 / 86

On to step 5:
86 can be fit into 693 8 times, resulting in a remainder of 5.
Record the quotient 8 as the next digit in the result. 
Result so far: 358.0
If we take 688 away from 693, we end up with 5.
Append the next digit (0) from the dividend to 5 and continue with: 50 / 86

Moving on to step 6:
86 can be fit into 50 0 times, resulting in a remainder of 50.
The next digit of our result is 0. 
Result so far: 3580.0
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 7:
When dividing 500 by 86, we get 5 with a remainder of 70.
Put 5 as the next digit of the answer. 
Result so far: 3580.5
Subtracting 430 from 500 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 8:
86 can be fit into 700 8 times, resulting in a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 3580.58
If we subtract 688 from 700, we 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.

Going ahead to step 9:
When dividing 120 by 86, we get 1 with a remainder of 34.
The next digit of our result is 1. 
Result so far: 3580.581
If we take 86 away from 120, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 10:
86 goes into 340 3 times with a remainder of 82.
Use 3 as the next digit of our solution. 
Result so far: 3580.5813
Deduct 258 from 340 and we're left 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.

Let's proceed to step 11:
820 divided by 86 is 9 with a remainder of 46.
Put 9 as the next digit of the answer. 
Result so far: 3580.58139
The remainder is 46 after subtracting 774 from 820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 12:
The number 86 fits into 460 5 times, leaving a remainder of 30.
The next digit of our result is 5. 
Result so far: 3580.581395
The remainder is 30 after subtracting 430 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 13:
86 goes into 300 3 times with a remainder of 42.
The number 3 becomes the next digit in our result. 
Result so far: 3580.5813953
If we take 258 away from 300, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 14:
If we divide 420 by 86, we get 4 and a remainder of 76.
Write down 4 as next digit of the result. 
Result so far: 3580.58139534
Subtracting 344 from 420 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Our division results in 3580.58139534 with a remaining 7.6e-08.
