We look at the division of 638077 by 42 
Let's see how many times 42 fits into 638077.

Let's proceed to step 1:
42 can be fit into 6 0 times, resulting in a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 42

Step 2:
42 goes into 63 1 times with a remainder of 21.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 42 from 63 and we're left with 21.
Grab the next digit (8) from the dividend, add it to 21, then carry on: 218 / 42

Advancing to step 3:
If we divide 218 by 42, we get 5 and a remainder of 8.
The next digit of our result is 5. 
Result so far: 15.0
The remainder is 8 after subtracting 210 from 218.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 42

Let's proceed to step 4:
80 divided by 42 is 1 with a remainder of 38.
Write down 1 as next digit of the result. 
Result so far: 151.0
If we take 42 away from 80, we end up with 38.
Append the next digit (7) from the dividend to 38 and continue with: 387 / 42

Let's proceed to step 5:
387 divided by 42 is 9 with a remainder of 9.
Put 9 as the next digit of the answer. 
Result so far: 1519.0
The remainder is 9 after subtracting 378 from 387.
Grab the next digit (7) from the dividend, add it to 9, then carry on: 97 / 42

Going ahead to step 6:
42 goes into 97 2 times with a remainder of 13.
Put 2 as the next digit of the answer. 
Result so far: 15192.0
If we take 84 away from 97, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 7:
42 can be fit into 130 3 times, resulting in a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 15192.3
Deduct 126 from 130 and we're left 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.

On to step 8:
If we divide 40 by 42, we get 0 and a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 15192.3
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 9:
When dividing 400 by 42, we get 9 with a remainder of 22.
Write down 9 as next digit of the result. 
Result so far: 15192.309
If we subtract 378 from 400, we get 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 10:
If we divide 220 by 42, we get 5 and a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 15192.3095
Subtracting 210 from 220 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 11:
100 divided by 42 is 2 with a remainder of 16.
The next digit of our result is 2. 
Result so far: 15192.30952
Subtracting 84 from 100 leaves us 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.

Let's proceed to step 12:
160 divided by 42 is 3 with a remainder of 34.
Write down 3 as next digit of the result. 
Result so far: 15192.309523
Subtract 126 from 160 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 13:
If we divide 340 by 42, we get 8 and a remainder of 4.
The next digit of our result is 8. 
Result so far: 15192.3095238
If we take 336 away from 340, 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.

Going ahead to step 14:
42 goes into 40 0 times with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 15192.3095238
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

In conclusion, the division gives 15192.3095238 with a balance of 4e-08.
