233964 ÷ 69 
The aim is to understand the frequency of 69 in 233964.

On to step 1:
69 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 69

Let's proceed to step 2:
69 goes into 23 0 times with a remainder of 23.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 23 leaves us with 23.
Take the next digit (3) from the dividend and append it to 23, then repeat: 233 / 69

Moving on to step 3:
69 goes into 233 3 times with a remainder of 26.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 207 from 233 leaves us with 26.
Fetch the next digit (9) from the dividend, attach it to 26 and continue: 269 / 69

Going ahead to step 4:
69 goes into 269 3 times with a remainder of 62.
Put 3 as the next digit of the answer. 
Result so far: 33.0
If we take 207 away from 269, we end up with 62.
Append the next digit (6) from the dividend to 62 and continue with: 626 / 69

On to step 5:
626 divided by 69 is 9 with a remainder of 5.
Write down 9 as next digit of the result. 
Result so far: 339.0
If we subtract 621 from 626, we get 5.
Bring next digit (4) of the dividend behind the 5 and repeat the process: 54 / 69

Let's proceed to step 6:
69 goes into 54 0 times with a remainder of 54.
Use 0 as the next digit of our solution. 
Result so far: 3390.0
Deduct 0 from 54 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 7:
When dividing 540 by 69, we get 7 with a remainder of 57.
The number 7 becomes the next digit in our result. 
Result so far: 3390.7
If we take 483 away from 540, we end up with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Moving on to step 8:
If we divide 570 by 69, we get 8 and a remainder of 18.
Use 8 as the next digit of our solution. 
Result so far: 3390.78
Deduct 552 from 570 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 9:
69 can be fit into 180 2 times, resulting in a remainder of 42.
Write down 2 as next digit of the result. 
Result so far: 3390.782
If we take 138 away from 180, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 10:
420 divided by 69 is 6 with a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 3390.7826
If we subtract 414 from 420, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 11:
69 can be fit into 60 0 times, resulting in a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 3390.7826
Deduct 0 from 60 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 12:
If we divide 600 by 69, we get 8 and a remainder of 48.
Record the quotient 8 as the next digit in the result. 
Result so far: 3390.782608
Subtracting 552 from 600 leaves us 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.

Let's proceed to step 13:
If we divide 480 by 69, we get 6 and a remainder of 66.
The next digit of our result is 6. 
Result so far: 3390.7826086
If we take 414 away from 480, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 14:
69 goes into 660 9 times with a remainder of 39.
The number 9 becomes the next digit in our result. 
Result so far: 3390.78260869
Subtracting 621 from 660 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Our division results in 3390.78260869 with a remaining 3.9e-08.
