Let's divide 150101 by 42
Let's see how many times 42 fits into 150101.

Let's proceed to step 1:
The number 42 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 42

Step 2:
If we divide 15 by 42, we get 0 and a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 15 after subtracting 0 from 15.
Bring next digit (0) of the dividend behind the 15 and repeat the process: 150 / 42

Moving on to step 3:
The number 42 fits into 150 3 times, leaving a remainder of 24.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 126 from 150, we get 24.
Fetch the next digit (1) from the dividend, attach it to 24 and continue: 241 / 42

Moving on to step 4:
42 goes into 241 5 times with a remainder of 31.
Use 5 as the next digit of our solution. 
Result so far: 35.0
Subtract 210 from 241 to get 31.
Fetch the next digit (0) from the dividend, attach it to 31 and continue: 310 / 42

On to step 5:
The number 42 fits into 310 7 times, leaving a remainder of 16.
Put 7 as the next digit of the answer. 
Result so far: 357.0
The remainder is 16 after subtracting 294 from 310.
Fetch the next digit (1) from the dividend, attach it to 16 and continue: 161 / 42

Step 6:
42 can be fit into 161 3 times, resulting in a remainder of 35.
Record the quotient 3 as the next digit in the result. 
Result so far: 3573.0
Subtract 126 from 161 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 7:
If we divide 350 by 42, we get 8 and a remainder of 14.
The next digit of our result is 8. 
Result so far: 3573.8
If we take 336 away from 350, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 8:
When dividing 140 by 42, we get 3 with a remainder of 14.
Write down 3 as next digit of the result. 
Result so far: 3573.83
If we take 126 away from 140, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 9:
140 divided by 42 is 3 with a remainder of 14.
The next digit of our result is 3. 
Result so far: 3573.833
Deduct 126 from 140 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

After the division, we end up with 3573.833 and a remainder of 0.0014.
