We look at the division of 283149 by 45 
The aim is to understand the frequency of 45 in 283149.

Moving on to step 1:
When dividing 2 by 45, we get 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 45

Moving on to step 2:
45 goes into 28 0 times with a remainder of 28.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 28 to get 28.
Append the next digit (3) from the dividend to 28 and continue with: 283 / 45

Moving on to step 3:
45 can be fit into 283 6 times, resulting in a remainder of 13.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we take 270 away from 283, we end up with 13.
Fetch the next digit (1) from the dividend, attach it to 13 and continue: 131 / 45

Moving on to step 4:
The number 45 fits into 131 2 times, leaving a remainder of 41.
The number 2 becomes the next digit in our result. 
Result so far: 62.0
Deduct 90 from 131 and we're left with 41.
Append the next digit (4) from the dividend to 41 and continue with: 414 / 45

Advancing to step 5:
45 can be fit into 414 9 times, resulting in a remainder of 9.
The number 9 becomes the next digit in our result. 
Result so far: 629.0
If we take 405 away from 414, we end up with 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 45

Step 6:
The number 45 fits into 99 2 times, leaving a remainder of 9.
Write down 2 as next digit of the result. 
Result so far: 6292.0
If we take 90 away from 99, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 7:
45 goes into 90 2 times with a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 6292.2
Subtract 90 from 90 to 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.

Let's proceed to step 8:
If we divide 0 by 45, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 6292.2
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.

Advancing to step 9:
The number 45 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 6292.2
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 6292.2 with a remainder of 0.0.
