148029 ÷ 42 
We're looking to find how many times 42 goes into 148029.

Going ahead to step 1:
The number 42 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 42

On to step 2:
If we divide 14 by 42, we get 0 and a remainder of 14.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 14 to get 14.
Bring next digit (8) of the dividend behind the 14 and repeat the process: 148 / 42

Moving on to step 3:
If we divide 148 by 42, we get 3 and a remainder of 22.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 126 away from 148, we end up with 22.
Include the next digit (0) from the dividend after 22, then repeat: 220 / 42

Going ahead to step 4:
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: 35.0
Subtracting 210 from 220 leaves us with 10.
Take the next digit (2) from the dividend and append it to 10, then repeat: 102 / 42

Going ahead to step 5:
102 divided by 42 is 2 with a remainder of 18.
Record the quotient 2 as the next digit in the result. 
Result so far: 352.0
If we subtract 84 from 102, we get 18.
Fetch the next digit (9) from the dividend, attach it to 18 and continue: 189 / 42

Going ahead to step 6:
When dividing 189 by 42, we get 4 with a remainder of 21.
The number 4 becomes the next digit in our result. 
Result so far: 3524.0
Subtracting 168 from 189 leaves us 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.

Moving on to step 7:
When dividing 210 by 42, we get 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 3524.5
The remainder is 0 after subtracting 210 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
If we divide 0 by 42, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 3524.5
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.

Going ahead to step 9:
The number 42 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 3524.5
If we subtract 0 from 0, we get 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 quotient of the division is 3524.5, and the remainder is 0.0.
