725844 divided by 42 
We want to figure out the number of times 725844 can be divided by 42.

Step 1:
42 can be fit into 7 0 times, resulting in a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 42

On to step 2:
42 can be fit into 72 1 times, resulting in a remainder of 30.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 42 from 72 to get 30.
Bring next digit (5) of the dividend behind the 30 and repeat the process: 305 / 42

Step 3:
305 divided by 42 is 7 with a remainder of 11.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
Deduct 294 from 305 and we're left with 11.
Take the next digit (8) from the dividend and append it to 11, then repeat: 118 / 42

Moving on to step 4:
When dividing 118 by 42, we get 2 with a remainder of 34.
Write down 2 as next digit of the result. 
Result so far: 172.0
If we take 84 away from 118, we end up with 34.
Take the next digit (4) from the dividend and append it to 34, then repeat: 344 / 42

Advancing to step 5:
If we divide 344 by 42, we get 8 and a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 1728.0
Subtract 336 from 344 to get 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 42

On to step 6:
If we divide 84 by 42, we get 2 and a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 17282.0
Subtract 84 from 84 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.

Advancing to step 7:
42 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 17282.0
Deduct 0 from 0 and we're left 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:
When dividing 0 by 42, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 17282.0
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 quotient of the division is 17282.0, and the remainder is 0.0.
