39687106 divided by 306 
Let's see how many times 306 fits into 39687106.

On to step 1:
If we divide 3 by 306, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 306

On to step 2:
The number 306 fits into 39 0 times, leaving a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 39 after subtracting 0 from 39.
Bring next digit (6) of the dividend behind the 39 and repeat the process: 396 / 306

Let's proceed to step 3:
396 divided by 306 is 1 with a remainder of 90.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 306 from 396 leaves us with 90.
Fetch the next digit (8) from the dividend, attach it to 90 and continue: 908 / 306

Advancing to step 4:
If we divide 908 by 306, we get 2 and a remainder of 296.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
The remainder is 296 after subtracting 612 from 908.
Take the next digit (7) from the dividend and append it to 296, then repeat: 2967 / 306

Let's proceed to step 5:
306 goes into 2967 9 times with a remainder of 213.
Put 9 as the next digit of the answer. 
Result so far: 129.0
The remainder is 213 after subtracting 2754 from 2967.
Fetch the next digit (1) from the dividend, attach it to 213 and continue: 2131 / 306

On to step 6:
306 goes into 2131 6 times with a remainder of 295.
The next digit of our result is 6. 
Result so far: 1296.0
If we take 1836 away from 2131, we end up with 295.
Append the next digit (0) from the dividend to 295 and continue with: 2950 / 306

Moving on to step 7:
The number 306 fits into 2950 9 times, leaving a remainder of 196.
The next digit of our result is 9. 
Result so far: 12969.0
Deduct 2754 from 2950 and we're left with 196.
Take the next digit (6) from the dividend and append it to 196, then repeat: 1966 / 306

On to step 8:
306 can be fit into 1966 6 times, resulting in a remainder of 130.
Use 6 as the next digit of our solution. 
Result so far: 129696.0
Subtract 1836 from 1966 to get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

On to step 9:
1300 divided by 306 is 4 with a remainder of 76.
Record the quotient 4 as the next digit in the result. 
Result so far: 129696.4
The remainder is 76 after subtracting 1224 from 1300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Going ahead to step 10:
The number 306 fits into 760 2 times, leaving a remainder of 148.
The next digit of our result is 2. 
Result so far: 129696.42
Deduct 612 from 760 and we're left with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Advancing to step 11:
306 goes into 1480 4 times with a remainder of 256.
Put 4 as the next digit of the answer. 
Result so far: 129696.424
If we take 1224 away from 1480, we end up with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Step 12:
If we divide 2560 by 306, we get 8 and a remainder of 112.
Write down 8 as next digit of the result. 
Result so far: 129696.4248
If we subtract 2448 from 2560, we get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Advancing to step 13:
306 can be fit into 1120 3 times, resulting in a remainder of 202.
The number 3 becomes the next digit in our result. 
Result so far: 129696.42483
Subtracting 918 from 1120 leaves us with 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Going ahead to step 14:
306 can be fit into 2020 6 times, resulting in a remainder of 184.
The number 6 becomes the next digit in our result. 
Result so far: 129696.424836
The remainder is 184 after subtracting 1836 from 2020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Going ahead to step 15:
The number 306 fits into 1840 6 times, leaving a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 129696.4248366
If we take 1836 away from 1840, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

After the division, we end up with 129696.4248366 and a remainder of 4e-08.
