639382 divided by 42 
Let's see how many times 42 fits into 639382.

Advancing to step 1:
The number 42 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 42

Let's proceed to step 2:
42 can be fit into 63 1 times, resulting in a remainder of 21.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 42 from 63, we get 21.
Take the next digit (9) from the dividend and append it to 21, then repeat: 219 / 42

Step 3:
When dividing 219 by 42, we get 5 with a remainder of 9.
Put 5 as the next digit of the answer. 
Result so far: 15.0
If we subtract 210 from 219, we get 9.
Append the next digit (3) from the dividend to 9 and continue with: 93 / 42

Let's proceed to step 4:
42 can be fit into 93 2 times, resulting in a remainder of 9.
Put 2 as the next digit of the answer. 
Result so far: 152.0
The remainder is 9 after subtracting 84 from 93.
Bring next digit (8) of the dividend behind the 9 and repeat the process: 98 / 42

Moving on to step 5:
42 goes into 98 2 times with a remainder of 14.
The number 2 becomes the next digit in our result. 
Result so far: 1522.0
Subtracting 84 from 98 leaves us with 14.
Fetch the next digit (2) from the dividend, attach it to 14 and continue: 142 / 42

Step 6:
The number 42 fits into 142 3 times, leaving a remainder of 16.
The next digit of our result is 3. 
Result so far: 15223.0
If we subtract 126 from 142, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 7:
If we divide 160 by 42, we get 3 and a remainder of 34.
Put 3 as the next digit of the answer. 
Result so far: 15223.3
If we take 126 away from 160, 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.

Going ahead to step 8:
42 can be fit into 340 8 times, resulting in a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 15223.38
The remainder is 4 after subtracting 336 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 9:
The number 42 fits into 40 0 times, leaving a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 15223.38
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 10:
42 goes into 400 9 times with a remainder of 22.
Write down 9 as next digit of the result. 
Result so far: 15223.3809
Deduct 378 from 400 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 11:
The number 42 fits into 220 5 times, leaving a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 15223.38095
If we subtract 210 from 220, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 12:
If we divide 100 by 42, we get 2 and a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 15223.380952
Deduct 84 from 100 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 13:
When dividing 160 by 42, we get 3 with a remainder of 34.
Write down 3 as next digit of the result. 
Result so far: 15223.3809523
Deduct 126 from 160 and we're left 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.

Let's proceed to step 14:
When dividing 340 by 42, we get 8 with a remainder of 4.
The next digit of our result is 8. 
Result so far: 15223.38095238
If we subtract 336 from 340, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Our division results in 15223.38095238 with a remaining 4e-09.
