We're dividing 85856 by 45 
The aim is to understand the frequency of 45 in 85856.

Advancing to step 1:
8 divided by 45 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 45

On to step 2:
45 goes into 85 1 times with a remainder of 40.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 45 from 85 leaves us with 40.
Grab the next digit (8) from the dividend, add it to 40, then carry on: 408 / 45

Advancing to step 3:
408 divided by 45 is 9 with a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 19.0
The remainder is 3 after subtracting 405 from 408.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 45

Advancing to step 4:
35 divided by 45 is 0 with a remainder of 35.
Write down 0 as next digit of the result. 
Result so far: 190.0
Subtract 0 from 35 to get 35.
Take the next digit (6) from the dividend and append it to 35, then repeat: 356 / 45

Advancing to step 5:
45 goes into 356 7 times with a remainder of 41.
Use 7 as the next digit of our solution. 
Result so far: 1907.0
Subtract 315 from 356 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Let's proceed to step 6:
When dividing 410 by 45, we get 9 with a remainder of 5.
Put 9 as the next digit of the answer. 
Result so far: 1907.9
Subtract 405 from 410 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.

Going ahead to step 7:
If we divide 50 by 45, we get 1 and a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 1907.91
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.

Advancing to step 8:
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: 1907.911
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.

The final result is 1907.911 with a remainder of 0.0005.
