We're dividing 872613 by 42 
We want to figure out the number of times 872613 can be divided by 42.

Going ahead to step 1:
42 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 42

Step 2:
When dividing 87 by 42, we get 2 with a remainder of 3.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 84 from 87 and we're left with 3.
Fetch the next digit (2) from the dividend, attach it to 3 and continue: 32 / 42

Moving on to step 3:
32 divided by 42 is 0 with a remainder of 32.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
Subtracting 0 from 32 leaves us with 32.
Append the next digit (6) from the dividend to 32 and continue with: 326 / 42

Let's proceed to step 4:
326 divided by 42 is 7 with a remainder of 32.
The next digit of our result is 7. 
Result so far: 207.0
Subtracting 294 from 326 leaves us with 32.
Fetch the next digit (1) from the dividend, attach it to 32 and continue: 321 / 42

On to step 5:
When dividing 321 by 42, we get 7 with a remainder of 27.
The number 7 becomes the next digit in our result. 
Result so far: 2077.0
Subtract 294 from 321 to get 27.
Append the next digit (3) from the dividend to 27 and continue with: 273 / 42

Moving on to step 6:
If we divide 273 by 42, we get 6 and a remainder of 21.
Record the quotient 6 as the next digit in the result. 
Result so far: 20776.0
If we subtract 252 from 273, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 7:
42 can be fit into 210 5 times, resulting in a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 20776.5
Subtracting 210 from 210 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on 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: 20776.5
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.

Going ahead to step 9:
When dividing 0 by 42, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 20776.5
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.

The final result is 20776.5 with a remainder of 0.0.
