Let's divide 66099984 by 674
The aim is to understand the frequency of 674 in 66099984.

Step 1:
6 divided by 674 is 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 674

Going ahead to step 2:
If we divide 66 by 674, we get 0 and a remainder of 66.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 66 and we're left with 66.
Append the next digit (0) from the dividend to 66 and continue with: 660 / 674

Moving on to step 3:
660 divided by 674 is 0 with a remainder of 660.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 660 leaves us with 660.
Include the next digit (9) from the dividend after 660, then repeat: 6609 / 674

Moving on to step 4:
When dividing 6609 by 674, we get 9 with a remainder of 543.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtract 6066 from 6609 to get 543.
Bring next digit (9) of the dividend behind the 543 and repeat the process: 5439 / 674

Moving on to step 5:
674 goes into 5439 8 times with a remainder of 47.
Write down 8 as next digit of the result. 
Result so far: 98.0
Subtract 5392 from 5439 to get 47.
Take the next digit (9) from the dividend and append it to 47, then repeat: 479 / 674

Let's proceed to step 6:
479 divided by 674 is 0 with a remainder of 479.
Record the quotient 0 as the next digit in the result. 
Result so far: 980.0
Subtracting 0 from 479 leaves us with 479.
Include the next digit (8) from the dividend after 479, then repeat: 4798 / 674

Let's proceed to step 7:
The number 674 fits into 4798 7 times, leaving a remainder of 80.
The next digit of our result is 7. 
Result so far: 9807.0
If we subtract 4718 from 4798, we get 80.
Take the next digit (4) from the dividend and append it to 80, then repeat: 804 / 674

Moving on to step 8:
The number 674 fits into 804 1 times, leaving a remainder of 130.
Write down 1 as next digit of the result. 
Result so far: 98071.0
If we subtract 674 from 804, we get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Advancing to step 9:
674 can be fit into 1300 1 times, resulting in a remainder of 626.
The number 1 becomes the next digit in our result. 
Result so far: 98071.1
Subtract 674 from 1300 to get 626.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6260, and continue the process.

Advancing to step 10:
674 can be fit into 6260 9 times, resulting in a remainder of 194.
The next digit of our result is 9. 
Result so far: 98071.19
If we take 6066 away from 6260, we end up with 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

Step 11:
1940 divided by 674 is 2 with a remainder of 592.
The next digit of our result is 2. 
Result so far: 98071.192
Subtracting 1348 from 1940 leaves us with 592.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5920, and continue the process.

Advancing to step 12:
674 goes into 5920 8 times with a remainder of 528.
Put 8 as the next digit of the answer. 
Result so far: 98071.1928
If we subtract 5392 from 5920, we get 528.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

Let's proceed to step 13:
5280 divided by 674 is 7 with a remainder of 562.
Record the quotient 7 as the next digit in the result. 
Result so far: 98071.19287
Subtract 4718 from 5280 to get 562.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5620, and continue the process.

Moving on to step 14:
674 can be fit into 5620 8 times, resulting in a remainder of 228.
Use 8 as the next digit of our solution. 
Result so far: 98071.192878
Subtracting 5392 from 5620 leaves us with 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

On to step 15:
2280 divided by 674 is 3 with a remainder of 258.
Use 3 as the next digit of our solution. 
Result so far: 98071.1928783
If we subtract 2022 from 2280, we get 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

On to step 16:
2580 divided by 674 is 3 with a remainder of 558.
The number 3 becomes the next digit in our result. 
Result so far: 98071.19287833
If we subtract 2022 from 2580, we get 558.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5580, and continue the process.

The final result is 98071.19287833 with a remainder of 5.58e-07.
