529059 ÷ 42 
Let's see how many times 42 fits into 529059.

Advancing to step 1:
If we divide 5 by 42, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Take the next digit (2) from the dividend and append it to 5, then repeat: 52 / 42

Moving on to step 2:
The number 42 fits into 52 1 times, leaving a remainder of 10.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 42 from 52 to get 10.
Bring next digit (9) of the dividend behind the 10 and repeat the process: 109 / 42

Step 3:
The number 42 fits into 109 2 times, leaving a remainder of 25.
Put 2 as the next digit of the answer. 
Result so far: 12.0
The remainder is 25 after subtracting 84 from 109.
Bring next digit (0) of the dividend behind the 25 and repeat the process: 250 / 42

Going ahead to step 4:
The number 42 fits into 250 5 times, leaving a remainder of 40.
Write down 5 as next digit of the result. 
Result so far: 125.0
Subtracting 210 from 250 leaves us with 40.
Fetch the next digit (5) from the dividend, attach it to 40 and continue: 405 / 42

Advancing to step 5:
If we divide 405 by 42, we get 9 and a remainder of 27.
Record the quotient 9 as the next digit in the result. 
Result so far: 1259.0
The remainder is 27 after subtracting 378 from 405.
Include the next digit (9) from the dividend after 27, then repeat: 279 / 42

On to step 6:
42 can be fit into 279 6 times, resulting in a remainder of 27.
Write down 6 as next digit of the result. 
Result so far: 12596.0
Subtract 252 from 279 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 7:
If we divide 270 by 42, we get 6 and a remainder of 18.
Record the quotient 6 as the next digit in the result. 
Result so far: 12596.6
Deduct 252 from 270 and we're left 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 8:
42 goes into 180 4 times with a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 12596.64
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 9:
When dividing 120 by 42, we get 2 with a remainder of 36.
Put 2 as the next digit of the answer. 
Result so far: 12596.642
Subtract 84 from 120 to get 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 10:
42 can be fit into 360 8 times, resulting in a remainder of 24.
The next digit of our result is 8. 
Result so far: 12596.6428
Subtracting 336 from 360 leaves us 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.

Let's proceed to step 11:
240 divided by 42 is 5 with a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 12596.64285
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.

Advancing to step 12:
42 goes into 300 7 times with a remainder of 6.
The next digit of our result is 7. 
Result so far: 12596.642857
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.

Step 13:
42 goes into 60 1 times with a remainder of 18.
Write down 1 as next digit of the result. 
Result so far: 12596.6428571
If we subtract 42 from 60, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 14:
The number 42 fits into 180 4 times, leaving a remainder of 12.
The number 4 becomes the next digit in our result. 
Result so far: 12596.64285714
Subtracting 168 from 180 leaves us 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.

After the division, we end up with 12596.64285714 and a remainder of 1.2e-08.
