512481 divided by 45 
The aim is to understand the frequency of 45 in 512481.

Moving on to step 1:
The number 45 fits into 5 0 times, leaving a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 45

Let's proceed to step 2:
45 goes into 51 1 times with a remainder of 6.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 45 from 51 to get 6.
Bring next digit (2) of the dividend behind the 6 and repeat the process: 62 / 45

On to step 3:
45 goes into 62 1 times with a remainder of 17.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Subtract 45 from 62 to get 17.
Take the next digit (4) from the dividend and append it to 17, then repeat: 174 / 45

Advancing to step 4:
45 can be fit into 174 3 times, resulting in a remainder of 39.
Record the quotient 3 as the next digit in the result. 
Result so far: 113.0
The remainder is 39 after subtracting 135 from 174.
Bring next digit (8) of the dividend behind the 39 and repeat the process: 398 / 45

On to step 5:
45 can be fit into 398 8 times, resulting in a remainder of 38.
Put 8 as the next digit of the answer. 
Result so far: 1138.0
Deduct 360 from 398 and we're left with 38.
Append the next digit (1) from the dividend to 38 and continue with: 381 / 45

Advancing to step 6:
45 goes into 381 8 times with a remainder of 21.
Write down 8 as next digit of the result. 
Result so far: 11388.0
Deduct 360 from 381 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 7:
45 goes into 210 4 times with a remainder of 30.
Write down 4 as next digit of the result. 
Result so far: 11388.4
The remainder is 30 after subtracting 180 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 8:
If we divide 300 by 45, we get 6 and a remainder of 30.
The number 6 becomes the next digit in our result. 
Result so far: 11388.46
If we subtract 270 from 300, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 9:
When dividing 300 by 45, we get 6 with a remainder of 30.
The next digit of our result is 6. 
Result so far: 11388.466
Deduct 270 from 300 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

In conclusion, the division gives 11388.466 with a balance of 0.003.
