We're dividing 479301 by 42 
The aim is to understand the frequency of 42 in 479301.

Advancing to step 1:
4 divided by 42 is 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (7) from the dividend and append it to 4, then repeat: 47 / 42

Advancing to step 2:
47 divided by 42 is 1 with a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 42 from 47 to get 5.
Include the next digit (9) from the dividend after 5, then repeat: 59 / 42

On to step 3:
If we divide 59 by 42, we get 1 and a remainder of 17.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Subtract 42 from 59 to get 17.
Grab the next digit (3) from the dividend, add it to 17, then carry on: 173 / 42

Let's proceed to step 4:
If we divide 173 by 42, we get 4 and a remainder of 5.
The next digit of our result is 4. 
Result so far: 114.0
Subtract 168 from 173 to get 5.
Append the next digit (0) from the dividend to 5 and continue with: 50 / 42

Let's proceed to step 5:
The number 42 fits into 50 1 times, leaving a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 1141.0
Subtracting 42 from 50 leaves us with 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 42

Moving on to step 6:
42 goes into 81 1 times with a remainder of 39.
Use 1 as the next digit of our solution. 
Result so far: 11411.0
If we subtract 42 from 81, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Step 7:
390 divided by 42 is 9 with a remainder of 12.
Use 9 as the next digit of our solution. 
Result so far: 11411.9
Subtracting 378 from 390 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 8:
120 divided by 42 is 2 with a remainder of 36.
Record the quotient 2 as the next digit in the result. 
Result so far: 11411.92
If we take 84 away from 120, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 9:
42 can be fit into 360 8 times, resulting in a remainder of 24.
Put 8 as the next digit of the answer. 
Result so far: 11411.928
If we take 336 away from 360, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 10:
When dividing 240 by 42, we get 5 with a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 11411.9285
Subtracting 210 from 240 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 11:
The number 42 fits into 300 7 times, leaving a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 11411.92857
Deduct 294 from 300 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 12:
42 can be fit into 60 1 times, resulting in a remainder of 18.
The next digit of our result is 1. 
Result so far: 11411.928571
The remainder is 18 after subtracting 42 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 13:
The number 42 fits into 180 4 times, leaving a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 11411.9285714
If we take 168 away from 180, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 14:
If we divide 120 by 42, we get 2 and a remainder of 36.
Record the quotient 2 as the next digit in the result. 
Result so far: 11411.92857142
The remainder is 36 after subtracting 84 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

The final outcome is 11411.92857142, with a leftover of 3.6e-08.
