525281 divided by 42 
We want to figure out the number of times 525281 can be divided by 42.

Moving on to step 1:
If we divide 5 by 42, we get 0 and a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Take the next digit (2) from the dividend and append it to 5, then repeat: 52 / 42

Going ahead to step 2:
The number 42 fits into 52 1 times, leaving a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 42 from 52 and we're left with 10.
Fetch the next digit (5) from the dividend, attach it to 10 and continue: 105 / 42

Moving on to step 3:
When dividing 105 by 42, we get 2 with a remainder of 21.
Write down 2 as next digit of the result. 
Result so far: 12.0
The remainder is 21 after subtracting 84 from 105.
Append the next digit (2) from the dividend to 21 and continue with: 212 / 42

Going ahead to step 4:
42 goes into 212 5 times with a remainder of 2.
The next digit of our result is 5. 
Result so far: 125.0
If we take 210 away from 212, we end up with 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 42

Going ahead to step 5:
42 can be fit into 28 0 times, resulting in a remainder of 28.
The number 0 becomes the next digit in our result. 
Result so far: 1250.0
If we take 0 away from 28, we end up with 28.
Include the next digit (1) from the dividend after 28, then repeat: 281 / 42

Step 6:
When dividing 281 by 42, we get 6 with a remainder of 29.
Put 6 as the next digit of the answer. 
Result so far: 12506.0
Deduct 252 from 281 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Advancing to step 7:
42 goes into 290 6 times with a remainder of 38.
The next digit of our result is 6. 
Result so far: 12506.6
Subtracting 252 from 290 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 8:
380 divided by 42 is 9 with a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 12506.69
If we take 378 away from 380, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 9:
42 goes into 20 0 times with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 12506.69
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 10:
200 divided by 42 is 4 with a remainder of 32.
Record the quotient 4 as the next digit in the result. 
Result so far: 12506.6904
Subtract 168 from 200 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 11:
42 goes into 320 7 times with a remainder of 26.
Write down 7 as next digit of the result. 
Result so far: 12506.69047
If we subtract 294 from 320, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 12:
The number 42 fits into 260 6 times, leaving a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 12506.690476
The remainder is 8 after subtracting 252 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 13:
If we divide 80 by 42, we get 1 and a remainder of 38.
The number 1 becomes the next digit in our result. 
Result so far: 12506.6904761
Subtracting 42 from 80 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 14:
42 goes into 380 9 times with a remainder of 2.
The next digit of our result is 9. 
Result so far: 12506.69047619
If we take 378 away from 380, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The final result is 12506.69047619 with a remainder of 2e-09.
