30659509 ÷ 674 
The aim is to understand the frequency of 674 in 30659509.

Step 1:
If we divide 3 by 674, we get 0 and a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 674

Let's proceed to step 2:
674 can be fit into 30 0 times, resulting in a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 30 to get 30.
Take the next digit (6) from the dividend and append it to 30, then repeat: 306 / 674

Going ahead to step 3:
The number 674 fits into 306 0 times, leaving a remainder of 306.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 306, we get 306.
Grab the next digit (5) from the dividend, add it to 306, then carry on: 3065 / 674

Advancing to step 4:
3065 divided by 674 is 4 with a remainder of 369.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 2696 from 3065, we get 369.
Bring next digit (9) of the dividend behind the 369 and repeat the process: 3699 / 674

Moving on to step 5:
674 goes into 3699 5 times with a remainder of 329.
Record the quotient 5 as the next digit in the result. 
Result so far: 45.0
Subtract 3370 from 3699 to get 329.
Include the next digit (5) from the dividend after 329, then repeat: 3295 / 674

Let's proceed to step 6:
If we divide 3295 by 674, we get 4 and a remainder of 599.
Record the quotient 4 as the next digit in the result. 
Result so far: 454.0
Subtract 2696 from 3295 to get 599.
Include the next digit (0) from the dividend after 599, then repeat: 5990 / 674

Going ahead to step 7:
674 goes into 5990 8 times with a remainder of 598.
Use 8 as the next digit of our solution. 
Result so far: 4548.0
The remainder is 598 after subtracting 5392 from 5990.
Take the next digit (9) from the dividend and append it to 598, then repeat: 5989 / 674

Advancing to step 8:
674 can be fit into 5989 8 times, resulting in a remainder of 597.
Use 8 as the next digit of our solution. 
Result so far: 45488.0
Subtract 5392 from 5989 to get 597.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5970, and continue the process.

Going ahead to step 9:
674 can be fit into 5970 8 times, resulting in a remainder of 578.
The number 8 becomes the next digit in our result. 
Result so far: 45488.8
Deduct 5392 from 5970 and we're left with 578.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5780, and continue the process.

Advancing to step 10:
674 can be fit into 5780 8 times, resulting in a remainder of 388.
Put 8 as the next digit of the answer. 
Result so far: 45488.88
If we subtract 5392 from 5780, we get 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

The final result is 45488.88 with a remainder of 0.388.
