We look at the division of 152142 by 42 
Let's see how many times 42 fits into 152142.

Let's proceed to step 1:
If we divide 1 by 42, we get 0 and 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.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 42

On to step 2:
15 divided by 42 is 0 with a remainder of 15.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 15 to get 15.
Fetch the next digit (2) from the dividend, attach it to 15 and continue: 152 / 42

Going ahead to step 3:
When dividing 152 by 42, we get 3 with a remainder of 26.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 126 away from 152, we end up with 26.
Fetch the next digit (1) from the dividend, attach it to 26 and continue: 261 / 42

Going ahead to step 4:
261 divided by 42 is 6 with a remainder of 9.
Record the quotient 6 as the next digit in the result. 
Result so far: 36.0
If we take 252 away from 261, we end up with 9.
Append the next digit (4) from the dividend to 9 and continue with: 94 / 42

Advancing to step 5:
When dividing 94 by 42, we get 2 with a remainder of 10.
Record the quotient 2 as the next digit in the result. 
Result so far: 362.0
The remainder is 10 after subtracting 84 from 94.
Append the next digit (2) from the dividend to 10 and continue with: 102 / 42

Step 6:
42 can be fit into 102 2 times, resulting in a remainder of 18.
The next digit of our result is 2. 
Result so far: 3622.0
If we subtract 84 from 102, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 7:
When dividing 180 by 42, we get 4 with a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 3622.4
Subtract 168 from 180 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 8:
When dividing 120 by 42, we get 2 with a remainder of 36.
Write down 2 as next digit of the result. 
Result so far: 3622.42
If we take 84 away from 120, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 9:
When dividing 360 by 42, we get 8 with a remainder of 24.
The next digit of our result is 8. 
Result so far: 3622.428
If we subtract 336 from 360, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 10:
240 divided by 42 is 5 with a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 3622.4285
Subtract 210 from 240 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 11:
The number 42 fits into 300 7 times, leaving a remainder of 6.
The next digit of our result is 7. 
Result so far: 3622.42857
Subtracting 294 from 300 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 12:
If we divide 60 by 42, we get 1 and a remainder of 18.
Use 1 as the next digit of our solution. 
Result so far: 3622.428571
Deduct 42 from 60 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 13:
180 divided by 42 is 4 with a remainder of 12.
The next digit of our result is 4. 
Result so far: 3622.4285714
If we take 168 away from 180, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 14:
When dividing 120 by 42, we get 2 with a remainder of 36.
The number 2 becomes the next digit in our result. 
Result so far: 3622.42857142
Subtract 84 from 120 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

After the division, we end up with 3622.42857142 and a remainder of 3.6e-08.
