We look at the division of 20350609 by 168 
The aim is to understand the frequency of 168 in 20350609.

Going ahead to step 1:
168 goes into 2 0 times with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 168

Moving on to step 2:
The number 168 fits into 20 0 times, leaving a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 20 after subtracting 0 from 20.
Take the next digit (3) from the dividend and append it to 20, then repeat: 203 / 168

Going ahead to step 3:
203 divided by 168 is 1 with a remainder of 35.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 168 away from 203, we end up with 35.
Include the next digit (5) from the dividend after 35, then repeat: 355 / 168

On to step 4:
168 can be fit into 355 2 times, resulting in a remainder of 19.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Subtract 336 from 355 to get 19.
Bring next digit (0) of the dividend behind the 19 and repeat the process: 190 / 168

Advancing to step 5:
When dividing 190 by 168, we get 1 with a remainder of 22.
Write down 1 as next digit of the result. 
Result so far: 121.0
Subtract 168 from 190 to get 22.
Append the next digit (6) from the dividend to 22 and continue with: 226 / 168

On to step 6:
The number 168 fits into 226 1 times, leaving a remainder of 58.
Put 1 as the next digit of the answer. 
Result so far: 1211.0
If we subtract 168 from 226, we get 58.
Grab the next digit (0) from the dividend, add it to 58, then carry on: 580 / 168

Going ahead to step 7:
When dividing 580 by 168, we get 3 with a remainder of 76.
The number 3 becomes the next digit in our result. 
Result so far: 12113.0
The remainder is 76 after subtracting 504 from 580.
Grab the next digit (9) from the dividend, add it to 76, then carry on: 769 / 168

Moving on to step 8:
168 goes into 769 4 times with a remainder of 97.
The next digit of our result is 4. 
Result so far: 121134.0
If we subtract 672 from 769, we get 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Step 9:
The number 168 fits into 970 5 times, leaving a remainder of 130.
The next digit of our result is 5. 
Result so far: 121134.5
Subtract 840 from 970 to get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Going ahead to step 10:
When dividing 1300 by 168, we get 7 with a remainder of 124.
Use 7 as the next digit of our solution. 
Result so far: 121134.57
Deduct 1176 from 1300 and we're left with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

On to step 11:
168 goes into 1240 7 times with a remainder of 64.
The number 7 becomes the next digit in our result. 
Result so far: 121134.577
Deduct 1176 from 1240 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Our division results in 121134.577 with a remaining 0.0064.
