887215 divided by 42 
We want to figure out the number of times 887215 can be divided by 42.

On to step 1:
If we divide 8 by 42, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (8) from the dividend, attach it to 8 and continue: 88 / 42

On to step 2:
42 can be fit into 88 2 times, resulting in a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 84 from 88 and we're left with 4.
Fetch the next digit (7) from the dividend, attach it to 4 and continue: 47 / 42

Step 3:
42 goes into 47 1 times with a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
Subtract 42 from 47 to get 5.
Take the next digit (2) from the dividend and append it to 5, then repeat: 52 / 42

Advancing to step 4:
The number 42 fits into 52 1 times, leaving a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 211.0
Subtracting 42 from 52 leaves us with 10.
Include the next digit (1) from the dividend after 10, then repeat: 101 / 42

Moving on to step 5:
The number 42 fits into 101 2 times, leaving a remainder of 17.
Use 2 as the next digit of our solution. 
Result so far: 2112.0
The remainder is 17 after subtracting 84 from 101.
Include the next digit (5) from the dividend after 17, then repeat: 175 / 42

Advancing to step 6:
42 can be fit into 175 4 times, resulting in a remainder of 7.
The next digit of our result is 4. 
Result so far: 21124.0
Deduct 168 from 175 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 7:
When dividing 70 by 42, we get 1 with a remainder of 28.
Use 1 as the next digit of our solution. 
Result so far: 21124.1
If we subtract 42 from 70, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 8:
42 can be fit into 280 6 times, resulting in a remainder of 28.
The number 6 becomes the next digit in our result. 
Result so far: 21124.16
Subtract 252 from 280 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 9:
42 goes into 280 6 times with a remainder of 28.
Record the quotient 6 as the next digit in the result. 
Result so far: 21124.166
Subtract 252 from 280 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Our division results in 21124.166 with a remaining 0.0028.
