Let's divide 253486 by 42
We're looking to find how many times 42 goes into 253486.

Let's proceed to step 1:
42 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 42

Moving on to step 2:
42 goes into 25 0 times with a remainder of 25.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 25, we get 25.
Include the next digit (3) from the dividend after 25, then repeat: 253 / 42

Advancing to step 3:
The number 42 fits into 253 6 times, leaving a remainder of 1.
The next digit of our result is 6. 
Result so far: 6.0
If we subtract 252 from 253, we get 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 42

Going ahead to step 4:
42 goes into 14 0 times with a remainder of 14.
Record the quotient 0 as the next digit in the result. 
Result so far: 60.0
Subtracting 0 from 14 leaves us with 14.
Bring next digit (8) of the dividend behind the 14 and repeat the process: 148 / 42

Going ahead to step 5:
148 divided by 42 is 3 with a remainder of 22.
Use 3 as the next digit of our solution. 
Result so far: 603.0
If we take 126 away from 148, we end up with 22.
Fetch the next digit (6) from the dividend, attach it to 22 and continue: 226 / 42

Moving on to step 6:
When dividing 226 by 42, we get 5 with a remainder of 16.
Use 5 as the next digit of our solution. 
Result so far: 6035.0
The remainder is 16 after subtracting 210 from 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 7:
The number 42 fits into 160 3 times, leaving a remainder of 34.
Put 3 as the next digit of the answer. 
Result so far: 6035.3
Subtracting 126 from 160 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 8:
The number 42 fits into 340 8 times, leaving a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 6035.38
The remainder is 4 after subtracting 336 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 9:
40 divided by 42 is 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 6035.38
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 10:
42 goes into 400 9 times with a remainder of 22.
The number 9 becomes the next digit in our result. 
Result so far: 6035.3809
Deduct 378 from 400 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 11:
42 goes into 220 5 times with a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 6035.38095
Subtracting 210 from 220 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 12:
100 divided by 42 is 2 with a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 6035.380952
If we subtract 84 from 100, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 13:
42 can be fit into 160 3 times, resulting in a remainder of 34.
The number 3 becomes the next digit in our result. 
Result so far: 6035.3809523
Subtracting 126 from 160 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 14:
The number 42 fits into 340 8 times, leaving a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 6035.38095238
If we take 336 away from 340, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final result is 6035.38095238 with a remainder of 4e-09.
