We're dividing 863750 by 45 
The aim is to understand the frequency of 45 in 863750.

On to step 1:
45 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 45

Advancing to step 2:
86 divided by 45 is 1 with a remainder of 41.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 45 from 86 to get 41.
Append the next digit (3) from the dividend to 41 and continue with: 413 / 45

Going ahead to step 3:
The number 45 fits into 413 9 times, leaving a remainder of 8.
The next digit of our result is 9. 
Result so far: 19.0
Subtracting 405 from 413 leaves us with 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 45

Advancing to step 4:
If we divide 87 by 45, we get 1 and a remainder of 42.
Write down 1 as next digit of the result. 
Result so far: 191.0
If we subtract 45 from 87, we get 42.
Append the next digit (5) from the dividend to 42 and continue with: 425 / 45

Going ahead to step 5:
425 divided by 45 is 9 with a remainder of 20.
The number 9 becomes the next digit in our result. 
Result so far: 1919.0
The remainder is 20 after subtracting 405 from 425.
Fetch the next digit (0) from the dividend, attach it to 20 and continue: 200 / 45

Moving on to step 6:
45 goes into 200 4 times with a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 19194.0
Subtract 180 from 200 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 7:
200 divided by 45 is 4 with a remainder of 20.
Record the quotient 4 as the next digit in the result. 
Result so far: 19194.4
Subtract 180 from 200 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 8:
200 divided by 45 is 4 with a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 19194.44
Deduct 180 from 200 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

In conclusion, the division gives 19194.44 with a balance of 0.02.
