We divide 438896 by 45
The aim is to understand the frequency of 45 in 438896.

On to step 1:
4 divided by 45 is 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 45

Step 2:
45 can be fit into 43 0 times, resulting in a remainder of 43.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 43, we get 43.
Take the next digit (8) from the dividend and append it to 43, then repeat: 438 / 45

Let's proceed to step 3:
45 goes into 438 9 times with a remainder of 33.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we subtract 405 from 438, we get 33.
Include the next digit (8) from the dividend after 33, then repeat: 338 / 45

Let's proceed to step 4:
45 can be fit into 338 7 times, resulting in a remainder of 23.
The next digit of our result is 7. 
Result so far: 97.0
Deduct 315 from 338 and we're left with 23.
Append the next digit (9) from the dividend to 23 and continue with: 239 / 45

Let's proceed to step 5:
239 divided by 45 is 5 with a remainder of 14.
The next digit of our result is 5. 
Result so far: 975.0
Subtracting 225 from 239 leaves us with 14.
Fetch the next digit (6) from the dividend, attach it to 14 and continue: 146 / 45

Advancing to step 6:
146 divided by 45 is 3 with a remainder of 11.
The number 3 becomes the next digit in our result. 
Result so far: 9753.0
The remainder is 11 after subtracting 135 from 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 7:
If we divide 110 by 45, we get 2 and a remainder of 20.
The next digit of our result is 2. 
Result so far: 9753.2
The remainder is 20 after subtracting 90 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 8:
When dividing 200 by 45, we get 4 with a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 9753.24
If we subtract 180 from 200, we 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.

Advancing to step 9:
200 divided by 45 is 4 with a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 9753.244
If we take 180 away from 200, 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.

The final outcome is 9753.244, with a leftover of 0.002.
