We look at the division of 66860941 by 608 
The aim is to understand the frequency of 608 in 66860941.

Moving on to step 1:
608 can be fit into 6 0 times, resulting in a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 608

Let's proceed to step 2:
66 divided by 608 is 0 with a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 66 and we're left with 66.
Bring next digit (8) of the dividend behind the 66 and repeat the process: 668 / 608

Let's proceed to step 3:
The number 608 fits into 668 1 times, leaving a remainder of 60.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 608 from 668 to get 60.
Bring next digit (6) of the dividend behind the 60 and repeat the process: 606 / 608

Step 4:
If we divide 606 by 608, we get 0 and a remainder of 606.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we take 0 away from 606, we end up with 606.
Fetch the next digit (0) from the dividend, attach it to 606 and continue: 6060 / 608

Step 5:
When dividing 6060 by 608, we get 9 with a remainder of 588.
The number 9 becomes the next digit in our result. 
Result so far: 109.0
Subtract 5472 from 6060 to get 588.
Fetch the next digit (9) from the dividend, attach it to 588 and continue: 5889 / 608

On to step 6:
If we divide 5889 by 608, we get 9 and a remainder of 417.
Write down 9 as next digit of the result. 
Result so far: 1099.0
If we take 5472 away from 5889, we end up with 417.
Fetch the next digit (4) from the dividend, attach it to 417 and continue: 4174 / 608

Moving on to step 7:
The number 608 fits into 4174 6 times, leaving a remainder of 526.
Use 6 as the next digit of our solution. 
Result so far: 10996.0
If we subtract 3648 from 4174, we get 526.
Bring next digit (1) of the dividend behind the 526 and repeat the process: 5261 / 608

On to step 8:
608 can be fit into 5261 8 times, resulting in a remainder of 397.
The next digit of our result is 8. 
Result so far: 109968.0
Deduct 4864 from 5261 and we're left with 397.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3970, and continue the process.

Advancing to step 9:
608 can be fit into 3970 6 times, resulting in a remainder of 322.
Record the quotient 6 as the next digit in the result. 
Result so far: 109968.6
If we subtract 3648 from 3970, we get 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Going ahead to step 10:
If we divide 3220 by 608, we get 5 and a remainder of 180.
Write down 5 as next digit of the result. 
Result so far: 109968.65
Deduct 3040 from 3220 and we're left with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

On to step 11:
When dividing 1800 by 608, we get 2 with a remainder of 584.
Write down 2 as next digit of the result. 
Result so far: 109968.652
Subtract 1216 from 1800 to get 584.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5840, and continue the process.

Step 12:
608 goes into 5840 9 times with a remainder of 368.
The number 9 becomes the next digit in our result. 
Result so far: 109968.6529
Deduct 5472 from 5840 and we're left with 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Moving on to step 13:
When dividing 3680 by 608, we get 6 with a remainder of 32.
The next digit of our result is 6. 
Result so far: 109968.65296
The remainder is 32 after subtracting 3648 from 3680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 14:
608 can be fit into 320 0 times, resulting in a remainder of 320.
Use 0 as the next digit of our solution. 
Result so far: 109968.65296
If we subtract 0 from 320, we get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Advancing to step 15:
If we divide 3200 by 608, we get 5 and a remainder of 160.
Record the quotient 5 as the next digit in the result. 
Result so far: 109968.6529605
If we take 3040 away from 3200, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Let's proceed to step 16:
608 can be fit into 1600 2 times, resulting in a remainder of 384.
The number 2 becomes the next digit in our result. 
Result so far: 109968.65296052
The remainder is 384 after subtracting 1216 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

The final outcome is 109968.65296052, with a leftover of 3.84e-07.
