We're dividing 46158 by 45 
The aim is to understand the frequency of 45 in 46158.

Going ahead to step 1:
If we divide 4 by 45, 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.
Append the next digit (6) from the dividend to 4 and continue with: 46 / 45

Let's proceed to step 2:
When dividing 46 by 45, we get 1 with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 45 from 46 to get 1.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 45

Advancing to step 3:
The number 45 fits into 11 0 times, leaving a remainder of 11.
The next digit of our result is 0. 
Result so far: 10.0
The remainder is 11 after subtracting 0 from 11.
Fetch the next digit (5) from the dividend, attach it to 11 and continue: 115 / 45

Moving on to step 4:
115 divided by 45 is 2 with a remainder of 25.
Write down 2 as next digit of the result. 
Result so far: 102.0
If we subtract 90 from 115, we get 25.
Take the next digit (8) from the dividend and append it to 25, then repeat: 258 / 45

Advancing to step 5:
When dividing 258 by 45, we get 5 with a remainder of 33.
Use 5 as the next digit of our solution. 
Result so far: 1025.0
If we take 225 away from 258, we end up with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Let's proceed to step 6:
When dividing 330 by 45, we get 7 with a remainder of 15.
Record the quotient 7 as the next digit in the result. 
Result so far: 1025.7
If we take 315 away from 330, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 7:
45 can be fit into 150 3 times, resulting in a remainder of 15.
Write down 3 as next digit of the result. 
Result so far: 1025.73
The remainder is 15 after subtracting 135 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 8:
45 goes into 150 3 times with a remainder of 15.
The next digit of our result is 3. 
Result so far: 1025.733
If we take 135 away from 150, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

After the division, we end up with 1025.733 and a remainder of 0.0015.
