28610405 ÷ 168 
The aim is to understand the frequency of 168 in 28610405.

Let's proceed to step 1:
If we divide 2 by 168, we get 0 and 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.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 168

Moving on to step 2:
When dividing 28 by 168, we get 0 with a remainder of 28.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 28 after subtracting 0 from 28.
Bring next digit (6) of the dividend behind the 28 and repeat the process: 286 / 168

Moving on to step 3:
When dividing 286 by 168, we get 1 with a remainder of 118.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 168 from 286, we get 118.
Fetch the next digit (1) from the dividend, attach it to 118 and continue: 1181 / 168

Moving on to step 4:
When dividing 1181 by 168, we get 7 with a remainder of 5.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
Deduct 1176 from 1181 and we're left with 5.
Include the next digit (0) from the dividend after 5, then repeat: 50 / 168

Let's proceed to step 5:
168 goes into 50 0 times with a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 170.0
Subtract 0 from 50 to get 50.
Grab the next digit (4) from the dividend, add it to 50, then carry on: 504 / 168

Step 6:
504 divided by 168 is 3 with a remainder of 0.
The next digit of our result is 3. 
Result so far: 1703.0
Deduct 504 from 504 and we're left with 0.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 168

Going ahead to step 7:
When dividing 0 by 168, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 17030.0
Deduct 0 from 0 and we're left with 0.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 168

On to step 8:
If we divide 5 by 168, we get 0 and a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 170300.0
Subtract 0 from 5 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 9:
If we divide 50 by 168, we get 0 and a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 170300.0
If we take 0 away from 50, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 10:
The number 168 fits into 500 2 times, leaving a remainder of 164.
The number 2 becomes the next digit in our result. 
Result so far: 170300.02
If we subtract 336 from 500, we get 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Going ahead to step 11:
168 goes into 1640 9 times with a remainder of 128.
The number 9 becomes the next digit in our result. 
Result so far: 170300.029
Deduct 1512 from 1640 and we're left with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Step 12:
The number 168 fits into 1280 7 times, leaving a remainder of 104.
Put 7 as the next digit of the answer. 
Result so far: 170300.0297
If we take 1176 away from 1280, we end up with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Moving on to step 13:
168 can be fit into 1040 6 times, resulting in a remainder of 32.
Put 6 as the next digit of the answer. 
Result so far: 170300.02976
If we subtract 1008 from 1040, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 14:
If we divide 320 by 168, we get 1 and a remainder of 152.
Record the quotient 1 as the next digit in the result. 
Result so far: 170300.029761
The remainder is 152 after subtracting 168 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Moving on to step 15:
168 goes into 1520 9 times with a remainder of 8.
Use 9 as the next digit of our solution. 
Result so far: 170300.0297619
The remainder is 8 after subtracting 1512 from 1520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 16:
When dividing 80 by 168, we get 0 with a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 170300.0297619
Subtract 0 from 80 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

After the division, we end up with 170300.0297619 and a remainder of 8e-08.
