We look at the division of 447386 by 42 
The aim is to understand the frequency of 42 in 447386.

Moving on to step 1:
If we divide 4 by 42, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Include the next digit (4) from the dividend after 4, then repeat: 44 / 42

Step 2:
If we divide 44 by 42, we get 1 and a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 42 from 44 leaves us with 2.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 42

On to step 3:
The number 42 fits into 27 0 times, leaving a remainder of 27.
Put 0 as the next digit of the answer. 
Result so far: 10.0
The remainder is 27 after subtracting 0 from 27.
Grab the next digit (3) from the dividend, add it to 27, then carry on: 273 / 42

Let's proceed to step 4:
273 divided by 42 is 6 with a remainder of 21.
Put 6 as the next digit of the answer. 
Result so far: 106.0
Subtracting 252 from 273 leaves us with 21.
Append the next digit (8) from the dividend to 21 and continue with: 218 / 42

Let's proceed to step 5:
If we divide 218 by 42, we get 5 and a remainder of 8.
Put 5 as the next digit of the answer. 
Result so far: 1065.0
If we take 210 away from 218, we end up with 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 42

Going ahead to step 6:
42 can be fit into 86 2 times, resulting in a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 10652.0
Subtracting 84 from 86 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 7:
If we divide 20 by 42, we get 0 and a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 10652.0
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 8:
If we divide 200 by 42, we get 4 and a remainder of 32.
Write down 4 as next digit of the result. 
Result so far: 10652.04
If we subtract 168 from 200, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 9:
When dividing 320 by 42, we get 7 with a remainder of 26.
Record the quotient 7 as the next digit in the result. 
Result so far: 10652.047
The remainder is 26 after subtracting 294 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 10:
If we divide 260 by 42, we get 6 and a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 10652.0476
If we subtract 252 from 260, we 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.

Let's proceed to step 11:
42 goes into 80 1 times with a remainder of 38.
Put 1 as the next digit of the answer. 
Result so far: 10652.04761
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.

Going ahead to step 12:
The number 42 fits into 380 9 times, leaving a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 10652.047619
If we take 378 away from 380, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 13:
If we divide 20 by 42, we get 0 and a remainder of 20.
The next digit of our result is 0. 
Result so far: 10652.047619
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 14:
200 divided by 42 is 4 with a remainder of 32.
The next digit of our result is 4. 
Result so far: 10652.04761904
If we take 168 away from 200, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

After the division, we end up with 10652.04761904 and a remainder of 3.2e-08.
