We look at the division of 253293 by 42 
We're looking to find how many times 42 goes into 253293.

Let's proceed to step 1:
If we divide 2 by 42, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 42

Going ahead to step 2:
If we divide 25 by 42, we get 0 and a remainder of 25.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 25 after subtracting 0 from 25.
Include the next digit (3) from the dividend after 25, then repeat: 253 / 42

On to step 3:
253 divided by 42 is 6 with a remainder of 1.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we subtract 252 from 253, we get 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 42

On to step 4:
If we divide 12 by 42, we get 0 and a remainder of 12.
The next digit of our result is 0. 
Result so far: 60.0
Deduct 0 from 12 and we're left with 12.
Fetch the next digit (9) from the dividend, attach it to 12 and continue: 129 / 42

On to step 5:
42 goes into 129 3 times with a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 603.0
The remainder is 3 after subtracting 126 from 129.
Grab the next digit (3) from the dividend, add it to 3, then carry on: 33 / 42

Step 6:
If we divide 33 by 42, we get 0 and a remainder of 33.
Write down 0 as next digit of the result. 
Result so far: 6030.0
The remainder is 33 after subtracting 0 from 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Moving on to step 7:
When dividing 330 by 42, we get 7 with a remainder of 36.
Put 7 as the next digit of the answer. 
Result so far: 6030.7
Subtracting 294 from 330 leaves us 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.

Advancing to step 8:
The number 42 fits into 360 8 times, leaving a remainder of 24.
The number 8 becomes the next digit in our result. 
Result so far: 6030.78
If we take 336 away from 360, we end up 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.

Advancing to step 9:
240 divided by 42 is 5 with a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 6030.785
Deduct 210 from 240 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 10:
42 can be fit into 300 7 times, resulting in a remainder of 6.
Use 7 as the next digit of our solution. 
Result so far: 6030.7857
Subtract 294 from 300 to get 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 11:
60 divided by 42 is 1 with a remainder of 18.
The number 1 becomes the next digit in our result. 
Result so far: 6030.78571
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.

On to step 12:
42 goes into 180 4 times with a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 6030.785714
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 13:
42 goes into 120 2 times with a remainder of 36.
Use 2 as the next digit of our solution. 
Result so far: 6030.7857142
Subtracting 84 from 120 leaves us 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.

On to step 14:
If we divide 360 by 42, we get 8 and a remainder of 24.
The number 8 becomes the next digit in our result. 
Result so far: 6030.78571428
The remainder is 24 after subtracting 336 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final result is 6030.78571428 with a remainder of 2.4e-08.
