We look at the division of 149819 by 42 
Our goal is to divide 149819 by 42.

Going ahead to step 1:
42 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 42

Step 2:
When dividing 14 by 42, we get 0 with a remainder of 14.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 14 after subtracting 0 from 14.
Include the next digit (9) from the dividend after 14, then repeat: 149 / 42

Let's proceed to step 3:
If we divide 149 by 42, we get 3 and a remainder of 23.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we take 126 away from 149, we end up with 23.
Fetch the next digit (8) from the dividend, attach it to 23 and continue: 238 / 42

Moving on to step 4:
When dividing 238 by 42, we get 5 with a remainder of 28.
Write down 5 as next digit of the result. 
Result so far: 35.0
Subtracting 210 from 238 leaves us with 28.
Grab the next digit (1) from the dividend, add it to 28, then carry on: 281 / 42

Going ahead to step 5:
281 divided by 42 is 6 with a remainder of 29.
The next digit of our result is 6. 
Result so far: 356.0
The remainder is 29 after subtracting 252 from 281.
Include the next digit (9) from the dividend after 29, then repeat: 299 / 42

On to step 6:
299 divided by 42 is 7 with a remainder of 5.
Record the quotient 7 as the next digit in the result. 
Result so far: 3567.0
The remainder is 5 after subtracting 294 from 299.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 7:
When dividing 50 by 42, we get 1 with a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 3567.1
Subtracting 42 from 50 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 8:
42 can be fit into 80 1 times, resulting in a remainder of 38.
Write down 1 as next digit of the result. 
Result so far: 3567.11
Deduct 42 from 80 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

After the division, we end up with 3567.11 and a remainder of 0.038.
