575153 ÷ 42 
We want to figure out the number of times 575153 can be divided by 42.

Step 1:
42 can be fit into 5 0 times, resulting in a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 42

Moving on to step 2:
42 can be fit into 57 1 times, resulting in a remainder of 15.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 42 from 57, we get 15.
Append the next digit (5) from the dividend to 15 and continue with: 155 / 42

Step 3:
The number 42 fits into 155 3 times, leaving a remainder of 29.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Deduct 126 from 155 and we're left with 29.
Fetch the next digit (1) from the dividend, attach it to 29 and continue: 291 / 42

Step 4:
291 divided by 42 is 6 with a remainder of 39.
The number 6 becomes the next digit in our result. 
Result so far: 136.0
The remainder is 39 after subtracting 252 from 291.
Include the next digit (5) from the dividend after 39, then repeat: 395 / 42

Step 5:
42 goes into 395 9 times with a remainder of 17.
Record the quotient 9 as the next digit in the result. 
Result so far: 1369.0
Subtracting 378 from 395 leaves us with 17.
Grab the next digit (3) from the dividend, add it to 17, then carry on: 173 / 42

Let's proceed to step 6:
173 divided by 42 is 4 with a remainder of 5.
Use 4 as the next digit of our solution. 
Result so far: 13694.0
If we take 168 away from 173, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 7:
42 can be fit into 50 1 times, resulting in a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 13694.1
If we take 42 away from 50, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 8:
The number 42 fits into 80 1 times, leaving a remainder of 38.
Put 1 as the next digit of the answer. 
Result so far: 13694.11
Deduct 42 from 80 and we're left 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.

The final outcome is 13694.11, with a leftover of 0.038.
