800693 divided by 42 
The aim is to understand the frequency of 42 in 800693.

Step 1:
If we divide 8 by 42, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 42

Moving on to step 2:
80 divided by 42 is 1 with a remainder of 38.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 42 away from 80, we end up with 38.
Fetch the next digit (0) from the dividend, attach it to 38 and continue: 380 / 42

Let's proceed to step 3:
The number 42 fits into 380 9 times, leaving a remainder of 2.
Put 9 as the next digit of the answer. 
Result so far: 19.0
The remainder is 2 after subtracting 378 from 380.
Fetch the next digit (6) from the dividend, attach it to 2 and continue: 26 / 42

Going ahead to step 4:
When dividing 26 by 42, we get 0 with a remainder of 26.
The number 0 becomes the next digit in our result. 
Result so far: 190.0
Subtract 0 from 26 to get 26.
Include the next digit (9) from the dividend after 26, then repeat: 269 / 42

Going ahead to step 5:
When dividing 269 by 42, we get 6 with a remainder of 17.
Use 6 as the next digit of our solution. 
Result so far: 1906.0
Deduct 252 from 269 and we're left with 17.
Grab the next digit (3) from the dividend, add it to 17, then carry on: 173 / 42

Moving on to step 6:
42 goes into 173 4 times with a remainder of 5.
Write down 4 as next digit of the result. 
Result so far: 19064.0
The remainder is 5 after subtracting 168 from 173.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 7:
The number 42 fits into 50 1 times, leaving a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 19064.1
Subtract 42 from 50 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 8:
If we divide 80 by 42, we get 1 and a remainder of 38.
Write down 1 as next digit of the result. 
Result so far: 19064.11
If we subtract 42 from 80, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

The quotient of the division is 19064.11, and the remainder is 0.038.
