We're dividing 847898 by 45 
The aim is to understand the frequency of 45 in 847898.

Going ahead to step 1:
When dividing 8 by 45, we get 0 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.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 45

Going ahead to step 2:
45 goes into 84 1 times with a remainder of 39.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 45 from 84 to get 39.
Fetch the next digit (7) from the dividend, attach it to 39 and continue: 397 / 45

Let's proceed to step 3:
When dividing 397 by 45, we get 8 with a remainder of 37.
Use 8 as the next digit of our solution. 
Result so far: 18.0
Deduct 360 from 397 and we're left with 37.
Fetch the next digit (8) from the dividend, attach it to 37 and continue: 378 / 45

Step 4:
45 goes into 378 8 times with a remainder of 18.
Record the quotient 8 as the next digit in the result. 
Result so far: 188.0
If we take 360 away from 378, we end up with 18.
Take the next digit (9) from the dividend and append it to 18, then repeat: 189 / 45

Step 5:
The number 45 fits into 189 4 times, leaving a remainder of 9.
Use 4 as the next digit of our solution. 
Result so far: 1884.0
If we subtract 180 from 189, we get 9.
Include the next digit (8) from the dividend after 9, then repeat: 98 / 45

On to step 6:
45 can be fit into 98 2 times, resulting in a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 18842.0
If we take 90 away from 98, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 7:
The number 45 fits into 80 1 times, leaving a remainder of 35.
Use 1 as the next digit of our solution. 
Result so far: 18842.1
Subtract 45 from 80 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 8:
45 goes into 350 7 times with a remainder of 35.
Write down 7 as next digit of the result. 
Result so far: 18842.17
If we take 315 away from 350, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 9:
The number 45 fits into 350 7 times, leaving a remainder of 35.
The next digit of our result is 7. 
Result so far: 18842.177
If we subtract 315 from 350, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

The final result is 18842.177 with a remainder of 0.0035.
