66500665 divided by 168 
The aim is to understand the frequency of 168 in 66500665.

Let's proceed to step 1:
6 divided by 168 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 168

Advancing to step 2:
168 can be fit into 66 0 times, resulting in a remainder of 66.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 66, we get 66.
Bring next digit (5) of the dividend behind the 66 and repeat the process: 665 / 168

Advancing to step 3:
168 can be fit into 665 3 times, resulting in a remainder of 161.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 161 after subtracting 504 from 665.
Append the next digit (0) from the dividend to 161 and continue with: 1610 / 168

Let's proceed to step 4:
When dividing 1610 by 168, we get 9 with a remainder of 98.
Write down 9 as next digit of the result. 
Result so far: 39.0
Deduct 1512 from 1610 and we're left with 98.
Append the next digit (0) from the dividend to 98 and continue with: 980 / 168

Step 5:
When dividing 980 by 168, we get 5 with a remainder of 140.
The next digit of our result is 5. 
Result so far: 395.0
If we subtract 840 from 980, we get 140.
Take the next digit (6) from the dividend and append it to 140, then repeat: 1406 / 168

Advancing to step 6:
168 goes into 1406 8 times with a remainder of 62.
Use 8 as the next digit of our solution. 
Result so far: 3958.0
Subtracting 1344 from 1406 leaves us with 62.
Bring next digit (6) of the dividend behind the 62 and repeat the process: 626 / 168

Step 7:
The number 168 fits into 626 3 times, leaving a remainder of 122.
Write down 3 as next digit of the result. 
Result so far: 39583.0
If we take 504 away from 626, we end up with 122.
Bring next digit (5) of the dividend behind the 122 and repeat the process: 1225 / 168

Moving on to step 8:
168 goes into 1225 7 times with a remainder of 49.
The next digit of our result is 7. 
Result so far: 395837.0
If we subtract 1176 from 1225, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Moving on to step 9:
When dividing 490 by 168, we get 2 with a remainder of 154.
Write down 2 as next digit of the result. 
Result so far: 395837.2
Subtract 336 from 490 to get 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Moving on to step 10:
168 can be fit into 1540 9 times, resulting in a remainder of 28.
Put 9 as the next digit of the answer. 
Result so far: 395837.29
If we take 1512 away from 1540, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 11:
168 can be fit into 280 1 times, resulting in a remainder of 112.
Record the quotient 1 as the next digit in the result. 
Result so far: 395837.291
If we take 168 away from 280, we end up with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Advancing to step 12:
1120 divided by 168 is 6 with a remainder of 112.
Write down 6 as next digit of the result. 
Result so far: 395837.2916
Subtracting 1008 from 1120 leaves us with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

On to step 13:
When dividing 1120 by 168, we get 6 with a remainder of 112.
Record the quotient 6 as the next digit in the result. 
Result so far: 395837.29166
If we take 1008 away from 1120, we end up with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

The final result is 395837.29166 with a remainder of 0.000112.
