28479008 ÷ 354 
The aim is to understand the frequency of 354 in 28479008.

Let's proceed to step 1:
2 divided by 354 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 354

Step 2:
28 divided by 354 is 0 with a remainder of 28.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 28 and we're left with 28.
Include the next digit (4) from the dividend after 28, then repeat: 284 / 354

Moving on to step 3:
If we divide 284 by 354, we get 0 and a remainder of 284.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 284 to get 284.
Take the next digit (7) from the dividend and append it to 284, then repeat: 2847 / 354

Let's proceed to step 4:
2847 divided by 354 is 8 with a remainder of 15.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtract 2832 from 2847 to get 15.
Bring next digit (9) of the dividend behind the 15 and repeat the process: 159 / 354

On to step 5:
354 can be fit into 159 0 times, resulting in a remainder of 159.
Put 0 as the next digit of the answer. 
Result so far: 80.0
Deduct 0 from 159 and we're left with 159.
Take the next digit (0) from the dividend and append it to 159, then repeat: 1590 / 354

Moving on to step 6:
The number 354 fits into 1590 4 times, leaving a remainder of 174.
Put 4 as the next digit of the answer. 
Result so far: 804.0
Subtracting 1416 from 1590 leaves us with 174.
Include the next digit (0) from the dividend after 174, then repeat: 1740 / 354

Step 7:
354 goes into 1740 4 times with a remainder of 324.
The number 4 becomes the next digit in our result. 
Result so far: 8044.0
If we take 1416 away from 1740, we end up with 324.
Bring next digit (8) of the dividend behind the 324 and repeat the process: 3248 / 354

Moving on to step 8:
3248 divided by 354 is 9 with a remainder of 62.
Use 9 as the next digit of our solution. 
Result so far: 80449.0
If we take 3186 away from 3248, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 9:
When dividing 620 by 354, we get 1 with a remainder of 266.
Use 1 as the next digit of our solution. 
Result so far: 80449.1
Subtract 354 from 620 to get 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

Step 10:
2660 divided by 354 is 7 with a remainder of 182.
Use 7 as the next digit of our solution. 
Result so far: 80449.17
If we take 2478 away from 2660, we end up with 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

Going ahead to step 11:
354 can be fit into 1820 5 times, resulting in a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 80449.175
If we subtract 1770 from 1820, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 12:
The number 354 fits into 500 1 times, leaving a remainder of 146.
Write down 1 as next digit of the result. 
Result so far: 80449.1751
Subtract 354 from 500 to get 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Going ahead to step 13:
If we divide 1460 by 354, we get 4 and a remainder of 44.
The number 4 becomes the next digit in our result. 
Result so far: 80449.17514
If we take 1416 away from 1460, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 14:
440 divided by 354 is 1 with a remainder of 86.
Record the quotient 1 as the next digit in the result. 
Result so far: 80449.175141
Subtract 354 from 440 to get 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Let's proceed to step 15:
When dividing 860 by 354, we get 2 with a remainder of 152.
The number 2 becomes the next digit in our result. 
Result so far: 80449.1751412
Subtracting 708 from 860 leaves us with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Advancing to step 16:
If we divide 1520 by 354, we get 4 and a remainder of 104.
Write down 4 as next digit of the result. 
Result so far: 80449.17514124
Deduct 1416 from 1520 and we're left with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

The final outcome is 80449.17514124, with a leftover of 1.04e-07.
