203888 ÷ 65 
The aim is to understand the frequency of 65 in 203888.

Advancing to step 1:
The number 65 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 65

Let's proceed to step 2:
When dividing 20 by 65, we get 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 20 after subtracting 0 from 20.
Grab the next digit (3) from the dividend, add it to 20, then carry on: 203 / 65

Let's proceed to step 3:
If we divide 203 by 65, we get 3 and a remainder of 8.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we take 195 away from 203, we end up with 8.
Append the next digit (8) from the dividend to 8 and continue with: 88 / 65

Going ahead to step 4:
65 goes into 88 1 times with a remainder of 23.
Put 1 as the next digit of the answer. 
Result so far: 31.0
If we take 65 away from 88, we end up with 23.
Include the next digit (8) from the dividend after 23, then repeat: 238 / 65

Let's proceed to step 5:
When dividing 238 by 65, we get 3 with a remainder of 43.
The number 3 becomes the next digit in our result. 
Result so far: 313.0
The remainder is 43 after subtracting 195 from 238.
Append the next digit (8) from the dividend to 43 and continue with: 438 / 65

Let's proceed to step 6:
When dividing 438 by 65, we get 6 with a remainder of 48.
Use 6 as the next digit of our solution. 
Result so far: 3136.0
Deduct 390 from 438 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 7:
65 can be fit into 480 7 times, resulting in a remainder of 25.
Record the quotient 7 as the next digit in the result. 
Result so far: 3136.7
If we take 455 away from 480, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 8:
When dividing 250 by 65, we get 3 with a remainder of 55.
Use 3 as the next digit of our solution. 
Result so far: 3136.73
The remainder is 55 after subtracting 195 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

On to step 9:
If we divide 550 by 65, we get 8 and a remainder of 30.
Put 8 as the next digit of the answer. 
Result so far: 3136.738
If we subtract 520 from 550, 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.

Going ahead to step 10:
65 can be fit into 300 4 times, resulting in a remainder of 40.
Use 4 as the next digit of our solution. 
Result so far: 3136.7384
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.

Step 11:
65 goes into 400 6 times with a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 3136.73846
Subtracting 390 from 400 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 12:
The number 65 fits into 100 1 times, leaving a remainder of 35.
The number 1 becomes the next digit in our result. 
Result so far: 3136.738461
If we subtract 65 from 100, 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.

Moving on to step 13:
350 divided by 65 is 5 with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 3136.7384615
Deduct 325 from 350 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 14:
65 goes into 250 3 times with a remainder of 55.
Put 3 as the next digit of the answer. 
Result so far: 3136.73846153
Subtracting 195 from 250 leaves us with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

After the division, we end up with 3136.73846153 and a remainder of 5.5e-08.
