168645 ÷ 69 
The aim is to understand the frequency of 69 in 168645.

Going ahead to step 1:
If we divide 1 by 69, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 69

Let's proceed to step 2:
The number 69 fits into 16 0 times, leaving a remainder of 16.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 16 leaves us with 16.
Grab the next digit (8) from the dividend, add it to 16, then carry on: 168 / 69

On to step 3:
The number 69 fits into 168 2 times, leaving a remainder of 30.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 138 away from 168, we end up with 30.
Bring next digit (6) of the dividend behind the 30 and repeat the process: 306 / 69

Step 4:
If we divide 306 by 69, we get 4 and a remainder of 30.
Put 4 as the next digit of the answer. 
Result so far: 24.0
Subtract 276 from 306 to get 30.
Append the next digit (4) from the dividend to 30 and continue with: 304 / 69

Advancing to step 5:
If we divide 304 by 69, we get 4 and a remainder of 28.
The next digit of our result is 4. 
Result so far: 244.0
If we take 276 away from 304, we end up with 28.
Append the next digit (5) from the dividend to 28 and continue with: 285 / 69

Let's proceed to step 6:
If we divide 285 by 69, we get 4 and a remainder of 9.
Use 4 as the next digit of our solution. 
Result so far: 2444.0
If we take 276 away from 285, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 7:
90 divided by 69 is 1 with a remainder of 21.
Use 1 as the next digit of our solution. 
Result so far: 2444.1
If we subtract 69 from 90, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 8:
210 divided by 69 is 3 with a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 2444.13
Deduct 207 from 210 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 9:
When dividing 30 by 69, we get 0 with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 2444.13
If we subtract 0 from 30, 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.

Step 10:
300 divided by 69 is 4 with a remainder of 24.
Put 4 as the next digit of the answer. 
Result so far: 2444.1304
The remainder is 24 after subtracting 276 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 11:
If we divide 240 by 69, we get 3 and a remainder of 33.
The next digit of our result is 3. 
Result so far: 2444.13043
Subtracting 207 from 240 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Advancing to step 12:
69 goes into 330 4 times with a remainder of 54.
Use 4 as the next digit of our solution. 
Result so far: 2444.130434
Subtract 276 from 330 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

On to step 13:
If we divide 540 by 69, we get 7 and a remainder of 57.
Put 7 as the next digit of the answer. 
Result so far: 2444.1304347
If we subtract 483 from 540, we get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Going ahead to step 14:
The number 69 fits into 570 8 times, leaving a remainder of 18.
The number 8 becomes the next digit in our result. 
Result so far: 2444.13043478
Subtract 552 from 570 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The final result is 2444.13043478 with a remainder of 1.8e-08.
