Let's divide 389907 by 42
We're looking to find how many times 42 goes into 389907.

Let's proceed to step 1:
42 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 42

Going ahead to step 2:
42 goes into 38 0 times with a remainder of 38.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 38 leaves us with 38.
Append the next digit (9) from the dividend to 38 and continue with: 389 / 42

Going ahead to step 3:
42 goes into 389 9 times with a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtracting 378 from 389 leaves us with 11.
Fetch the next digit (9) from the dividend, attach it to 11 and continue: 119 / 42

Going ahead to step 4:
If we divide 119 by 42, we get 2 and a remainder of 35.
Record the quotient 2 as the next digit in the result. 
Result so far: 92.0
Deduct 84 from 119 and we're left with 35.
Bring next digit (0) of the dividend behind the 35 and repeat the process: 350 / 42

Let's proceed to step 5:
When dividing 350 by 42, we get 8 with a remainder of 14.
Write down 8 as next digit of the result. 
Result so far: 928.0
Subtract 336 from 350 to get 14.
Take the next digit (7) from the dividend and append it to 14, then repeat: 147 / 42

Moving on to step 6:
The number 42 fits into 147 3 times, leaving a remainder of 21.
The next digit of our result is 3. 
Result so far: 9283.0
Deduct 126 from 147 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 7:
If we divide 210 by 42, we get 5 and a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 9283.5
Subtracting 210 from 210 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 8:
When dividing 0 by 42, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 9283.5
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 9:
The number 42 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 9283.5
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 9283.5 with a remainder of 0.0.
