We're dividing 939135 by 42 
Let's see how many times 42 fits into 939135.

Step 1:
The number 42 fits into 9 0 times, leaving a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Fetch the next digit (3) from the dividend, attach it to 9 and continue: 93 / 42

Step 2:
If we divide 93 by 42, we get 2 and a remainder of 9.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 84 from 93 leaves us with 9.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 42

Step 3:
If we divide 99 by 42, we get 2 and a remainder of 15.
Record the quotient 2 as the next digit in the result. 
Result so far: 22.0
If we subtract 84 from 99, we get 15.
Take the next digit (1) from the dividend and append it to 15, then repeat: 151 / 42

Step 4:
151 divided by 42 is 3 with a remainder of 25.
The next digit of our result is 3. 
Result so far: 223.0
If we subtract 126 from 151, we get 25.
Bring next digit (3) of the dividend behind the 25 and repeat the process: 253 / 42

On to step 5:
When dividing 253 by 42, we get 6 with a remainder of 1.
Write down 6 as next digit of the result. 
Result so far: 2236.0
Subtracting 252 from 253 leaves us with 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 42

On to step 6:
42 goes into 15 0 times with a remainder of 15.
The next digit of our result is 0. 
Result so far: 22360.0
Deduct 0 from 15 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 7:
The number 42 fits into 150 3 times, leaving a remainder of 24.
Put 3 as the next digit of the answer. 
Result so far: 22360.3
Deduct 126 from 150 and we're left with 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 8:
240 divided by 42 is 5 with a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 22360.35
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.

On to step 9:
42 goes into 300 7 times with a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 22360.357
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 10:
If we divide 60 by 42, we get 1 and a remainder of 18.
The next digit of our result is 1. 
Result so far: 22360.3571
Subtracting 42 from 60 leaves us 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.

Step 11:
The number 42 fits into 180 4 times, leaving a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 22360.35714
Deduct 168 from 180 and we're left 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.

Let's proceed to step 12:
42 goes into 120 2 times with a remainder of 36.
Use 2 as the next digit of our solution. 
Result so far: 22360.357142
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 13:
If we divide 360 by 42, we get 8 and a remainder of 24.
The next digit of our result is 8. 
Result so far: 22360.3571428
Subtract 336 from 360 to 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.

Advancing to step 14:
42 can be fit into 240 5 times, resulting in a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 22360.35714285
The remainder is 30 after subtracting 210 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The final result is 22360.35714285 with a remainder of 3e-08.
