Let's divide 459106 by 42
The aim is to understand the frequency of 42 in 459106.

On 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.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 42

On to step 2:
If we divide 45 by 42, we get 1 and a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 42 away from 45, we end up with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 42

Step 3:
42 can be fit into 39 0 times, resulting in a remainder of 39.
The next digit of our result is 0. 
Result so far: 10.0
Subtracting 0 from 39 leaves us with 39.
Bring next digit (1) of the dividend behind the 39 and repeat the process: 391 / 42

Step 4:
When dividing 391 by 42, we get 9 with a remainder of 13.
Use 9 as the next digit of our solution. 
Result so far: 109.0
Subtracting 378 from 391 leaves us with 13.
Fetch the next digit (0) from the dividend, attach it to 13 and continue: 130 / 42

Step 5:
42 can be fit into 130 3 times, resulting in a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 1093.0
If we take 126 away from 130, we end up with 4.
Fetch the next digit (6) from the dividend, attach it to 4 and continue: 46 / 42

Step 6:
42 goes into 46 1 times with a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 10931.0
Subtract 42 from 46 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 7:
40 divided by 42 is 0 with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 10931.0
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 8:
400 divided by 42 is 9 with a remainder of 22.
The next digit of our result is 9. 
Result so far: 10931.09
Deduct 378 from 400 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 9:
If we divide 220 by 42, we get 5 and a remainder of 10.
The next digit of our result is 5. 
Result so far: 10931.095
Deduct 210 from 220 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 10:
42 goes into 100 2 times with a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 10931.0952
Subtract 84 from 100 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 11:
42 can be fit into 160 3 times, resulting in a remainder of 34.
Use 3 as the next digit of our solution. 
Result so far: 10931.09523
If we take 126 away from 160, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 12:
340 divided by 42 is 8 with a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 10931.095238
Subtract 336 from 340 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 13:
42 goes into 40 0 times with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 10931.095238
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 14:
When dividing 400 by 42, we get 9 with a remainder of 22.
Write down 9 as next digit of the result. 
Result so far: 10931.09523809
Subtracting 378 from 400 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

The final result is 10931.09523809 with a remainder of 2.2e-08.
