365855 divided by 45 
The aim is to understand the frequency of 45 in 365855.

Moving on to step 1:
45 goes into 3 0 times with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (6) from the dividend, add it to 3, then carry on: 36 / 45

Moving on to step 2:
If we divide 36 by 45, we get 0 and a remainder of 36.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 36 to get 36.
Grab the next digit (5) from the dividend, add it to 36, then carry on: 365 / 45

Advancing to step 3:
365 divided by 45 is 8 with a remainder of 5.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we subtract 360 from 365, we get 5.
Append the next digit (8) from the dividend to 5 and continue with: 58 / 45

Moving on to step 4:
If we divide 58 by 45, we get 1 and a remainder of 13.
Put 1 as the next digit of the answer. 
Result so far: 81.0
The remainder is 13 after subtracting 45 from 58.
Take the next digit (5) from the dividend and append it to 13, then repeat: 135 / 45

Going ahead to step 5:
135 divided by 45 is 3 with a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 813.0
Deduct 135 from 135 and we're left with 0.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 45

Step 6:
45 can be fit into 5 0 times, resulting in a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 8130.0
If we subtract 0 from 5, 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.

Advancing to step 7:
The number 45 fits into 50 1 times, leaving a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 8130.1
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.

Moving on to step 8:
If we divide 50 by 45, we get 1 and a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 8130.11
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.

The final outcome is 8130.11, with a leftover of 0.005.
