2993178 ÷ 168 
The aim is to understand the frequency of 168 in 2993178.

Advancing to step 1:
2 divided by 168 is 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Bring next digit (9) of the dividend behind the 2 and repeat the process: 29 / 168

Going ahead to step 2:
168 can be fit into 29 0 times, resulting in a remainder of 29.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 29, we get 29.
Append the next digit (9) from the dividend to 29 and continue with: 299 / 168

Moving on to step 3:
The number 168 fits into 299 1 times, leaving a remainder of 131.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 168 from 299, we get 131.
Append the next digit (3) from the dividend to 131 and continue with: 1313 / 168

On to step 4:
When dividing 1313 by 168, we get 7 with a remainder of 137.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
If we take 1176 away from 1313, we end up with 137.
Take the next digit (1) from the dividend and append it to 137, then repeat: 1371 / 168

Let's proceed to step 5:
1371 divided by 168 is 8 with a remainder of 27.
Use 8 as the next digit of our solution. 
Result so far: 178.0
If we subtract 1344 from 1371, we get 27.
Fetch the next digit (7) from the dividend, attach it to 27 and continue: 277 / 168

Step 6:
The number 168 fits into 277 1 times, leaving a remainder of 109.
Put 1 as the next digit of the answer. 
Result so far: 1781.0
If we take 168 away from 277, we end up with 109.
Grab the next digit (8) from the dividend, add it to 109, then carry on: 1098 / 168

Moving on to step 7:
1098 divided by 168 is 6 with a remainder of 90.
Write down 6 as next digit of the result. 
Result so far: 17816.0
If we take 1008 away from 1098, we end up with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Step 8:
168 goes into 900 5 times with a remainder of 60.
Use 5 as the next digit of our solution. 
Result so far: 17816.5
If we take 840 away from 900, we end up 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.

Going ahead to step 9:
When dividing 600 by 168, we get 3 with a remainder of 96.
Put 3 as the next digit of the answer. 
Result so far: 17816.53
If we subtract 504 from 600, we get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Let's proceed to step 10:
960 divided by 168 is 5 with a remainder of 120.
Record the quotient 5 as the next digit in the result. 
Result so far: 17816.535
If we take 840 away from 960, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

On to step 11:
When dividing 1200 by 168, we get 7 with a remainder of 24.
The number 7 becomes the next digit in our result. 
Result so far: 17816.5357
If we take 1176 away from 1200, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 12:
The number 168 fits into 240 1 times, leaving a remainder of 72.
The number 1 becomes the next digit in our result. 
Result so far: 17816.53571
Subtracting 168 from 240 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 13:
If we divide 720 by 168, we get 4 and a remainder of 48.
Use 4 as the next digit of our solution. 
Result so far: 17816.535714
If we take 672 away from 720, we end up 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 14:
If we divide 480 by 168, we get 2 and a remainder of 144.
The next digit of our result is 2. 
Result so far: 17816.5357142
If we subtract 336 from 480, we get 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Advancing to step 15:
168 can be fit into 1440 8 times, resulting in a remainder of 96.
The next digit of our result is 8. 
Result so far: 17816.53571428
If we take 1344 away from 1440, we end up with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

The final outcome is 17816.53571428, with a leftover of 9.6e-08.
