520527 ÷ 42 
Our goal is to divide 520527 by 42.

Going ahead to step 1:
42 goes into 5 0 times with 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.
Grab the next digit (2) from the dividend, add it to 5, then carry on: 52 / 42

Advancing 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
If we subtract 42 from 52, we get 10.
Take the next digit (0) from the dividend and append it to 10, then repeat: 100 / 42

Advancing to step 3:
When dividing 100 by 42, we get 2 with a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 12.0
The remainder is 16 after subtracting 84 from 100.
Fetch the next digit (5) from the dividend, attach it to 16 and continue: 165 / 42

Going ahead to step 4:
When dividing 165 by 42, we get 3 with a remainder of 39.
Write down 3 as next digit of the result. 
Result so far: 123.0
Subtract 126 from 165 to get 39.
Take the next digit (2) from the dividend and append it to 39, then repeat: 392 / 42

Advancing to step 5:
392 divided by 42 is 9 with a remainder of 14.
The next digit of our result is 9. 
Result so far: 1239.0
If we take 378 away from 392, we end up with 14.
Append the next digit (7) from the dividend to 14 and continue with: 147 / 42

Advancing to step 6:
The number 42 fits into 147 3 times, leaving a remainder of 21.
The next digit of our result is 3. 
Result so far: 12393.0
If we take 126 away from 147, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 7:
42 goes into 210 5 times with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 12393.5
If we subtract 210 from 210, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 8:
The number 42 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 12393.5
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 9:
When dividing 0 by 42, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 12393.5
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 12393.5 with a balance of 0.0.
