We're dividing 861133 by 45 
The aim is to understand the frequency of 45 in 861133.

Moving on to step 1:
8 divided by 45 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 45

On to step 2:
When dividing 86 by 45, we get 1 with a remainder of 41.
The next digit of our result is 1. 
Result so far: 1.0
If we take 45 away from 86, we end up with 41.
Take the next digit (1) from the dividend and append it to 41, then repeat: 411 / 45

Going ahead to step 3:
When dividing 411 by 45, we get 9 with a remainder of 6.
Write down 9 as next digit of the result. 
Result so far: 19.0
The remainder is 6 after subtracting 405 from 411.
Bring next digit (1) of the dividend behind the 6 and repeat the process: 61 / 45

On to step 4:
If we divide 61 by 45, we get 1 and a remainder of 16.
Write down 1 as next digit of the result. 
Result so far: 191.0
The remainder is 16 after subtracting 45 from 61.
Take the next digit (3) from the dividend and append it to 16, then repeat: 163 / 45

On to step 5:
45 can be fit into 163 3 times, resulting in a remainder of 28.
The next digit of our result is 3. 
Result so far: 1913.0
If we take 135 away from 163, we end up with 28.
Take the next digit (3) from the dividend and append it to 28, then repeat: 283 / 45

Advancing to step 6:
When dividing 283 by 45, we get 6 with a remainder of 13.
The next digit of our result is 6. 
Result so far: 19136.0
Deduct 270 from 283 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 7:
45 goes into 130 2 times with a remainder of 40.
Write down 2 as next digit of the result. 
Result so far: 19136.2
If we subtract 90 from 130, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 8:
The number 45 fits into 400 8 times, leaving a remainder of 40.
Put 8 as the next digit of the answer. 
Result so far: 19136.28
Subtracting 360 from 400 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 9:
45 goes into 400 8 times with a remainder of 40.
Write down 8 as next digit of the result. 
Result so far: 19136.288
If we subtract 360 from 400, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final outcome is 19136.288, with a leftover of 0.004.
