Let's divide 481555 by 45
The aim is to understand the frequency of 45 in 481555.

On to step 1:
When dividing 4 by 45, we get 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Grab the next digit (8) from the dividend, add it to 4, then carry on: 48 / 45

On to step 2:
When dividing 48 by 45, we get 1 with a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 45 from 48 leaves us with 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 45

Going ahead to step 3:
When dividing 31 by 45, we get 0 with a remainder of 31.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtract 0 from 31 to get 31.
Grab the next digit (5) from the dividend, add it to 31, then carry on: 315 / 45

Advancing to step 4:
45 goes into 315 7 times with a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 107.0
Deduct 315 from 315 and we're left with 0.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 45

Step 5:
45 can be fit into 5 0 times, resulting in a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 1070.0
The remainder is 5 after subtracting 0 from 5.
Bring next digit (5) of the dividend behind the 5 and repeat the process: 55 / 45

Step 6:
45 can be fit into 55 1 times, resulting in a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 10701.0
Deduct 45 from 55 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 7:
45 can be fit into 100 2 times, resulting in a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 10701.2
Subtract 90 from 100 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
The number 45 fits into 100 2 times, leaving a remainder of 10.
Put 2 as the next digit of the answer. 
Result so far: 10701.22
Subtract 90 from 100 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final result is 10701.22 with a remainder of 0.01.
