20149 ÷ 76 
The aim is to understand the frequency of 76 in 20149.

Step 1:
When dividing 2 by 76, we get 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 76

On to step 2:
76 can be fit into 20 0 times, resulting in a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 20 and we're left with 20.
Include the next digit (1) from the dividend after 20, then repeat: 201 / 76

Advancing to step 3:
76 goes into 201 2 times with a remainder of 49.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 152 from 201 to get 49.
Bring next digit (4) of the dividend behind the 49 and repeat the process: 494 / 76

Going ahead to step 4:
76 can be fit into 494 6 times, resulting in a remainder of 38.
The next digit of our result is 6. 
Result so far: 26.0
Subtracting 456 from 494 leaves us with 38.
Grab the next digit (9) from the dividend, add it to 38, then carry on: 389 / 76

Going ahead to step 5:
389 divided by 76 is 5 with a remainder of 9.
The next digit of our result is 5. 
Result so far: 265.0
If we take 380 away from 389, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 6:
76 can be fit into 90 1 times, resulting in a remainder of 14.
Put 1 as the next digit of the answer. 
Result so far: 265.1
The remainder is 14 after subtracting 76 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 7:
76 can be fit into 140 1 times, resulting in a remainder of 64.
Put 1 as the next digit of the answer. 
Result so far: 265.11
The remainder is 64 after subtracting 76 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Our division results in 265.11 with a remaining 0.064.
