Let's divide 308685 by 42
We're looking to find how many times 42 goes into 308685.

Advancing to step 1:
42 goes into 3 0 times with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 42

Let's proceed to step 2:
42 goes into 30 0 times with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 30, we end up with 30.
Bring next digit (8) of the dividend behind the 30 and repeat the process: 308 / 42

Going ahead to step 3:
The number 42 fits into 308 7 times, leaving a remainder of 14.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Deduct 294 from 308 and we're left with 14.
Take the next digit (6) from the dividend and append it to 14, then repeat: 146 / 42

Moving on to step 4:
The number 42 fits into 146 3 times, leaving a remainder of 20.
Write down 3 as next digit of the result. 
Result so far: 73.0
Subtract 126 from 146 to get 20.
Append the next digit (8) from the dividend to 20 and continue with: 208 / 42

Going ahead to step 5:
42 can be fit into 208 4 times, resulting in a remainder of 40.
The number 4 becomes the next digit in our result. 
Result so far: 734.0
If we subtract 168 from 208, we get 40.
Take the next digit (5) from the dividend and append it to 40, then repeat: 405 / 42

Advancing to step 6:
42 can be fit into 405 9 times, resulting in a remainder of 27.
Write down 9 as next digit of the result. 
Result so far: 7349.0
Subtracting 378 from 405 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 7:
42 goes into 270 6 times with a remainder of 18.
Record the quotient 6 as the next digit in the result. 
Result so far: 7349.6
The remainder is 18 after subtracting 252 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 8:
180 divided by 42 is 4 with a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 7349.64
If we subtract 168 from 180, 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.

Moving on to step 9:
If we divide 120 by 42, we get 2 and a remainder of 36.
Put 2 as the next digit of the answer. 
Result so far: 7349.642
The remainder is 36 after subtracting 84 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 10:
42 can be fit into 360 8 times, resulting in a remainder of 24.
Record the quotient 8 as the next digit in the result. 
Result so far: 7349.6428
Subtract 336 from 360 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 11:
240 divided by 42 is 5 with a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 7349.64285
If we subtract 210 from 240, we get 30.
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 12:
42 goes into 300 7 times with a remainder of 6.
The number 7 becomes the next digit in our result. 
Result so far: 7349.642857
Deduct 294 from 300 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 13:
42 can be fit into 60 1 times, resulting in a remainder of 18.
The next digit of our result is 1. 
Result so far: 7349.6428571
The remainder is 18 after subtracting 42 from 60.
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 14:
42 goes into 180 4 times with a remainder of 12.
The next digit of our result is 4. 
Result so far: 7349.64285714
Subtracting 168 from 180 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final outcome is 7349.64285714, with a leftover of 1.2e-08.
