26720215 ÷ 168 
The aim is to understand the frequency of 168 in 26720215.

Advancing to step 1:
When dividing 2 by 168, we get 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Append the next digit (6) from the dividend to 2 and continue with: 26 / 168

Advancing to step 2:
The number 168 fits into 26 0 times, leaving a remainder of 26.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 26 after subtracting 0 from 26.
Take the next digit (7) from the dividend and append it to 26, then repeat: 267 / 168

Moving on to step 3:
The number 168 fits into 267 1 times, leaving a remainder of 99.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 168 from 267 and we're left with 99.
Include the next digit (2) from the dividend after 99, then repeat: 992 / 168

Advancing to step 4:
168 goes into 992 5 times with a remainder of 152.
Write down 5 as next digit of the result. 
Result so far: 15.0
Subtract 840 from 992 to get 152.
Include the next digit (0) from the dividend after 152, then repeat: 1520 / 168

Advancing to step 5:
1520 divided by 168 is 9 with a remainder of 8.
The number 9 becomes the next digit in our result. 
Result so far: 159.0
Subtract 1512 from 1520 to get 8.
Take the next digit (2) from the dividend and append it to 8, then repeat: 82 / 168

On to step 6:
168 goes into 82 0 times with a remainder of 82.
The number 0 becomes the next digit in our result. 
Result so far: 1590.0
Deduct 0 from 82 and we're left with 82.
Grab the next digit (1) from the dividend, add it to 82, then carry on: 821 / 168

Advancing to step 7:
The number 168 fits into 821 4 times, leaving a remainder of 149.
Put 4 as the next digit of the answer. 
Result so far: 15904.0
Subtracting 672 from 821 leaves us with 149.
Grab the next digit (5) from the dividend, add it to 149, then carry on: 1495 / 168

Moving on to step 8:
The number 168 fits into 1495 8 times, leaving a remainder of 151.
Put 8 as the next digit of the answer. 
Result so far: 159048.0
If we subtract 1344 from 1495, we get 151.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1510, and continue the process.

On to step 9:
When dividing 1510 by 168, we get 8 with a remainder of 166.
Write down 8 as next digit of the result. 
Result so far: 159048.8
Deduct 1344 from 1510 and we're left with 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Advancing to step 10:
When dividing 1660 by 168, we get 9 with a remainder of 148.
Record the quotient 9 as the next digit in the result. 
Result so far: 159048.89
Subtracting 1512 from 1660 leaves us with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Advancing to step 11:
168 goes into 1480 8 times with a remainder of 136.
Use 8 as the next digit of our solution. 
Result so far: 159048.898
Subtract 1344 from 1480 to get 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Step 12:
The number 168 fits into 1360 8 times, leaving a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 159048.8988
If we take 1344 away from 1360, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final result is 159048.8988 with a remainder of 0.00016.
