888601 divided by 42 
The aim is to understand the frequency of 42 in 888601.

On to step 1:
8 divided by 42 is 0 with 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.
Take the next digit (8) from the dividend and append it to 8, then repeat: 88 / 42

On to step 2:
If we divide 88 by 42, we get 2 and a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 84 from 88 leaves us with 4.
Bring next digit (8) of the dividend behind the 4 and repeat the process: 48 / 42

Moving on to step 3:
The number 42 fits into 48 1 times, leaving a remainder of 6.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
Subtracting 42 from 48 leaves us with 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 42

Let's proceed to step 4:
42 goes into 66 1 times with a remainder of 24.
Use 1 as the next digit of our solution. 
Result so far: 211.0
If we take 42 away from 66, we end up with 24.
Include the next digit (0) from the dividend after 24, then repeat: 240 / 42

Let's proceed to step 5:
If we divide 240 by 42, we get 5 and a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 2115.0
Subtract 210 from 240 to get 30.
Bring next digit (1) of the dividend behind the 30 and repeat the process: 301 / 42

Advancing to step 6:
The number 42 fits into 301 7 times, leaving a remainder of 7.
The number 7 becomes the next digit in our result. 
Result so far: 21157.0
If we take 294 away from 301, we end up 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.

Going ahead to step 7:
When dividing 70 by 42, we get 1 with a remainder of 28.
Write down 1 as next digit of the result. 
Result so far: 21157.1
Deduct 42 from 70 and we're left with 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 goes into 280 6 times with a remainder of 28.
The number 6 becomes the next digit in our result. 
Result so far: 21157.16
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.

Let's proceed to step 9:
The number 42 fits into 280 6 times, leaving a remainder of 28.
Put 6 as the next digit of the answer. 
Result so far: 21157.166
Subtracting 252 from 280 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

After the division, we end up with 21157.166 and a remainder of 0.0028.
