74389 ÷ 65 
The aim is to understand the frequency of 65 in 74389.

Step 1:
65 can be fit into 7 0 times, resulting in a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (4) from the dividend after 7, then repeat: 74 / 65

Advancing to step 2:
74 divided by 65 is 1 with a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 65 from 74, we get 9.
Bring next digit (3) of the dividend behind the 9 and repeat the process: 93 / 65

On to step 3:
If we divide 93 by 65, we get 1 and a remainder of 28.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Subtracting 65 from 93 leaves us with 28.
Grab the next digit (8) from the dividend, add it to 28, then carry on: 288 / 65

Step 4:
If we divide 288 by 65, we get 4 and a remainder of 28.
The number 4 becomes the next digit in our result. 
Result so far: 114.0
If we subtract 260 from 288, we get 28.
Bring next digit (9) of the dividend behind the 28 and repeat the process: 289 / 65

Moving on to step 5:
65 can be fit into 289 4 times, resulting in a remainder of 29.
Write down 4 as next digit of the result. 
Result so far: 1144.0
Subtract 260 from 289 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 6:
If we divide 290 by 65, we get 4 and a remainder of 30.
Record the quotient 4 as the next digit in the result. 
Result so far: 1144.4
If we subtract 260 from 290, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 7:
65 goes into 300 4 times with a remainder of 40.
The next digit of our result is 4. 
Result so far: 1144.44
Deduct 260 from 300 and we're left 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.

Our division results in 1144.44 with a remaining 0.04.
