423913 ÷ 46 
The aim is to understand the frequency of 46 in 423913.

Step 1:
If we divide 4 by 46, 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.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 46

Moving on to step 2:
42 divided by 46 is 0 with a remainder of 42.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 42 and we're left with 42.
Fetch the next digit (3) from the dividend, attach it to 42 and continue: 423 / 46

Let's proceed to step 3:
423 divided by 46 is 9 with a remainder of 9.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we take 414 away from 423, we end up with 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 46

Let's proceed to step 4:
When dividing 99 by 46, we get 2 with a remainder of 7.
Put 2 as the next digit of the answer. 
Result so far: 92.0
Subtract 92 from 99 to get 7.
Take the next digit (1) from the dividend and append it to 7, then repeat: 71 / 46

Advancing to step 5:
If we divide 71 by 46, we get 1 and a remainder of 25.
Record the quotient 1 as the next digit in the result. 
Result so far: 921.0
If we take 46 away from 71, we end up with 25.
Include the next digit (3) from the dividend after 25, then repeat: 253 / 46

Advancing to step 6:
When dividing 253 by 46, we get 5 with a remainder of 23.
Put 5 as the next digit of the answer. 
Result so far: 9215.0
Subtract 230 from 253 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 7:
230 divided by 46 is 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 9215.5
The remainder is 0 after subtracting 230 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 8:
0 divided by 46 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 9215.5
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 9:
If we divide 0 by 46, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 9215.5
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 9215.5 with a remainder of 0.0.
