We're dividing 283550 by 45 
The aim is to understand the frequency of 45 in 283550.

Going ahead to step 1:
45 can be fit into 2 0 times, resulting in a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 45

Let's proceed to step 2:
When dividing 28 by 45, we get 0 with a remainder of 28.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 28, we end up with 28.
Bring next digit (3) of the dividend behind the 28 and repeat the process: 283 / 45

Going ahead to step 3:
The number 45 fits into 283 6 times, leaving a remainder of 13.
Use 6 as the next digit of our solution. 
Result so far: 6.0
If we take 270 away from 283, we end up with 13.
Append the next digit (5) from the dividend to 13 and continue with: 135 / 45

Step 4:
When dividing 135 by 45, we get 3 with a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 63.0
If we subtract 135 from 135, we get 0.
Bring next digit (5) of the dividend behind the 0 and repeat the process: 5 / 45

Step 5:
If we divide 5 by 45, we get 0 and a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 630.0
Deduct 0 from 5 and we're left with 5.
Append the next digit (0) from the dividend to 5 and continue with: 50 / 45

Moving on to step 6:
When dividing 50 by 45, we get 1 with a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 6301.0
Subtract 45 from 50 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 7:
When dividing 50 by 45, we get 1 with a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 6301.1
If we subtract 45 from 50, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 8:
When dividing 50 by 45, we get 1 with a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 6301.11
Subtract 45 from 50 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

After the division, we end up with 6301.11 and a remainder of 0.005.
