412572 ÷ 42 
Let's see how many times 42 fits into 412572.

On to step 1:
42 goes into 4 0 times with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Grab the next digit (1) from the dividend, add it to 4, then carry on: 41 / 42

Moving on to step 2:
When dividing 41 by 42, we get 0 with a remainder of 41.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 41 leaves us with 41.
Fetch the next digit (2) from the dividend, attach it to 41 and continue: 412 / 42

Advancing to step 3:
42 can be fit into 412 9 times, resulting in a remainder of 34.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtracting 378 from 412 leaves us with 34.
Bring next digit (5) of the dividend behind the 34 and repeat the process: 345 / 42

Moving on to step 4:
The number 42 fits into 345 8 times, leaving a remainder of 9.
The number 8 becomes the next digit in our result. 
Result so far: 98.0
Subtract 336 from 345 to get 9.
Grab the next digit (7) from the dividend, add it to 9, then carry on: 97 / 42

Moving on to step 5:
42 goes into 97 2 times with a remainder of 13.
Write down 2 as next digit of the result. 
Result so far: 982.0
Subtract 84 from 97 to get 13.
Take the next digit (2) from the dividend and append it to 13, then repeat: 132 / 42

Advancing to step 6:
42 goes into 132 3 times with a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 9823.0
If we subtract 126 from 132, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 7:
The number 42 fits into 60 1 times, leaving a remainder of 18.
The next digit of our result is 1. 
Result so far: 9823.1
Subtract 42 from 60 to 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 8:
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: 9823.14
If we subtract 168 from 180, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 9:
120 divided by 42 is 2 with a remainder of 36.
The next digit of our result is 2. 
Result so far: 9823.142
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.

On to step 10:
If we divide 360 by 42, we get 8 and a remainder of 24.
Use 8 as the next digit of our solution. 
Result so far: 9823.1428
If we take 336 away from 360, we end up 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.

Going ahead to step 11:
When dividing 240 by 42, we get 5 with a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 9823.14285
Subtracting 210 from 240 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 12:
300 divided by 42 is 7 with a remainder of 6.
The number 7 becomes the next digit in our result. 
Result so far: 9823.142857
If we subtract 294 from 300, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 13:
60 divided by 42 is 1 with a remainder of 18.
Use 1 as the next digit of our solution. 
Result so far: 9823.1428571
Subtracting 42 from 60 leaves us 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 14:
When dividing 180 by 42, we get 4 with a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 9823.14285714
If we subtract 168 from 180, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The quotient of the division is 9823.14285714, and the remainder is 1.2e-08.
