We're dividing 212406 by 65 
The aim is to understand the frequency of 65 in 212406.

On to step 1:
65 can be fit into 2 0 times, resulting in a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 65

Moving on to step 2:
If we divide 21 by 65, we get 0 and a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Append the next digit (2) from the dividend to 21 and continue with: 212 / 65

On to step 3:
212 divided by 65 is 3 with a remainder of 17.
The next digit of our result is 3. 
Result so far: 3.0
The remainder is 17 after subtracting 195 from 212.
Grab the next digit (4) from the dividend, add it to 17, then carry on: 174 / 65

Moving on to step 4:
The number 65 fits into 174 2 times, leaving a remainder of 44.
Put 2 as the next digit of the answer. 
Result so far: 32.0
If we take 130 away from 174, we end up with 44.
Append the next digit (0) from the dividend to 44 and continue with: 440 / 65

Going ahead to step 5:
When dividing 440 by 65, we get 6 with a remainder of 50.
Record the quotient 6 as the next digit in the result. 
Result so far: 326.0
The remainder is 50 after subtracting 390 from 440.
Take the next digit (6) from the dividend and append it to 50, then repeat: 506 / 65

Step 6:
When dividing 506 by 65, we get 7 with a remainder of 51.
Write down 7 as next digit of the result. 
Result so far: 3267.0
The remainder is 51 after subtracting 455 from 506.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Step 7:
65 goes into 510 7 times with a remainder of 55.
Use 7 as the next digit of our solution. 
Result so far: 3267.7
Deduct 455 from 510 and we're left 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.

Step 8:
65 goes into 550 8 times with a remainder of 30.
Record the quotient 8 as the next digit in the result. 
Result so far: 3267.78
Subtracting 520 from 550 leaves us with 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 9:
When dividing 300 by 65, we get 4 with a remainder of 40.
Write down 4 as next digit of the result. 
Result so far: 3267.784
Subtracting 260 from 300 leaves us 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.

Let's proceed to step 10:
If we divide 400 by 65, we get 6 and a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 3267.7846
The remainder is 10 after subtracting 390 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 11:
100 divided by 65 is 1 with a remainder of 35.
Use 1 as the next digit of our solution. 
Result so far: 3267.78461
If we take 65 away from 100, 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 12:
If we divide 350 by 65, we get 5 and a remainder of 25.
The next digit of our result is 5. 
Result so far: 3267.784615
Subtract 325 from 350 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 13:
The number 65 fits into 250 3 times, leaving a remainder of 55.
The next digit of our result is 3. 
Result so far: 3267.7846153
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 14:
When dividing 550 by 65, we get 8 with a remainder of 30.
Write down 8 as next digit of the result. 
Result so far: 3267.78461538
Subtracting 520 from 550 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The final result is 3267.78461538 with a remainder of 3e-08.
