We're dividing 197888 by 45 
The aim is to understand the frequency of 45 in 197888.

Step 1:
45 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 45

Advancing to step 2:
If we divide 19 by 45, we get 0 and a remainder of 19.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 19, we end up with 19.
Bring next digit (7) of the dividend behind the 19 and repeat the process: 197 / 45

Going ahead to step 3:
197 divided by 45 is 4 with a remainder of 17.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtract 180 from 197 to get 17.
Grab the next digit (8) from the dividend, add it to 17, then carry on: 178 / 45

On to step 4:
When dividing 178 by 45, we get 3 with a remainder of 43.
Put 3 as the next digit of the answer. 
Result so far: 43.0
Deduct 135 from 178 and we're left with 43.
Grab the next digit (8) from the dividend, add it to 43, then carry on: 438 / 45

Going ahead to step 5:
When dividing 438 by 45, we get 9 with a remainder of 33.
Write down 9 as next digit of the result. 
Result so far: 439.0
Subtracting 405 from 438 leaves us with 33.
Grab the next digit (8) from the dividend, add it to 33, then carry on: 338 / 45

Moving on to step 6:
If we divide 338 by 45, we get 7 and a remainder of 23.
Write down 7 as next digit of the result. 
Result so far: 4397.0
Subtracting 315 from 338 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 7:
45 goes into 230 5 times with a remainder of 5.
The next digit of our result is 5. 
Result so far: 4397.5
Subtract 225 from 230 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.

On to step 8:
45 can be fit into 50 1 times, resulting in a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 4397.51
Subtracting 45 from 50 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 9:
50 divided by 45 is 1 with a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 4397.511
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 quotient of the division is 4397.511, and the remainder is 0.0005.
