We divide 51996003 by 168
The aim is to understand the frequency of 168 in 51996003.

Let's proceed to step 1:
5 divided by 168 is 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 168

Step 2:
168 can be fit into 51 0 times, resulting in a remainder of 51.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 51 leaves us with 51.
Include the next digit (9) from the dividend after 51, then repeat: 519 / 168

Going ahead to step 3:
168 can be fit into 519 3 times, resulting in a remainder of 15.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 15 after subtracting 504 from 519.
Append the next digit (9) from the dividend to 15 and continue with: 159 / 168

Step 4:
The number 168 fits into 159 0 times, leaving a remainder of 159.
The number 0 becomes the next digit in our result. 
Result so far: 30.0
If we subtract 0 from 159, we get 159.
Append the next digit (6) from the dividend to 159 and continue with: 1596 / 168

Advancing to step 5:
1596 divided by 168 is 9 with a remainder of 84.
The next digit of our result is 9. 
Result so far: 309.0
Subtracting 1512 from 1596 leaves us with 84.
Append the next digit (0) from the dividend to 84 and continue with: 840 / 168

Advancing to step 6:
168 can be fit into 840 5 times, resulting in a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 3095.0
If we subtract 840 from 840, we get 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 168

Moving on to step 7:
The number 168 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 30950.0
If we take 0 away from 0, we end up with 0.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 168

Step 8:
If we divide 3 by 168, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 309500.0
Subtract 0 from 3 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 9:
When dividing 30 by 168, we get 0 with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 309500.0
Subtract 0 from 30 to 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.

Advancing to step 10:
When dividing 300 by 168, we get 1 with a remainder of 132.
Record the quotient 1 as the next digit in the result. 
Result so far: 309500.01
If we subtract 168 from 300, we get 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Moving on to step 11:
The number 168 fits into 1320 7 times, leaving a remainder of 144.
Record the quotient 7 as the next digit in the result. 
Result so far: 309500.017
Subtracting 1176 from 1320 leaves us with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

On to step 12:
1440 divided by 168 is 8 with a remainder of 96.
The next digit of our result is 8. 
Result so far: 309500.0178
The remainder is 96 after subtracting 1344 from 1440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

On to step 13:
960 divided by 168 is 5 with a remainder of 120.
The number 5 becomes the next digit in our result. 
Result so far: 309500.01785
Subtract 840 from 960 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Advancing to step 14:
168 goes into 1200 7 times with a remainder of 24.
Write down 7 as next digit of the result. 
Result so far: 309500.017857
If we subtract 1176 from 1200, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 15:
The number 168 fits into 240 1 times, leaving a remainder of 72.
Record the quotient 1 as the next digit in the result. 
Result so far: 309500.0178571
Subtract 168 from 240 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 16:
168 goes into 720 4 times with a remainder of 48.
The number 4 becomes the next digit in our result. 
Result so far: 309500.01785714
Subtracting 672 from 720 leaves us 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.

After the division, we end up with 309500.01785714 and a remainder of 4.8e-08.
