We're dividing 28001382 by 357 
The aim is to understand the frequency of 357 in 28001382.

On to step 1:
The number 357 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 357

Let's proceed to step 2:
357 goes into 28 0 times with a remainder of 28.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 28, we get 28.
Fetch the next digit (0) from the dividend, attach it to 28 and continue: 280 / 357

Advancing to step 3:
If we divide 280 by 357, we get 0 and a remainder of 280.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 280, we get 280.
Grab the next digit (0) from the dividend, add it to 280, then carry on: 2800 / 357

Step 4:
When dividing 2800 by 357, we get 7 with a remainder of 301.
The next digit of our result is 7. 
Result so far: 7.0
Subtract 2499 from 2800 to get 301.
Fetch the next digit (1) from the dividend, attach it to 301 and continue: 3011 / 357

On to step 5:
If we divide 3011 by 357, we get 8 and a remainder of 155.
Put 8 as the next digit of the answer. 
Result so far: 78.0
Deduct 2856 from 3011 and we're left with 155.
Grab the next digit (3) from the dividend, add it to 155, then carry on: 1553 / 357

On to step 6:
1553 divided by 357 is 4 with a remainder of 125.
The next digit of our result is 4. 
Result so far: 784.0
If we subtract 1428 from 1553, we get 125.
Fetch the next digit (8) from the dividend, attach it to 125 and continue: 1258 / 357

Going ahead to step 7:
If we divide 1258 by 357, we get 3 and a remainder of 187.
The next digit of our result is 3. 
Result so far: 7843.0
Deduct 1071 from 1258 and we're left with 187.
Include the next digit (2) from the dividend after 187, then repeat: 1872 / 357

Step 8:
357 goes into 1872 5 times with a remainder of 87.
The next digit of our result is 5. 
Result so far: 78435.0
Deduct 1785 from 1872 and we're left with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Step 9:
870 divided by 357 is 2 with a remainder of 156.
Use 2 as the next digit of our solution. 
Result so far: 78435.2
Subtracting 714 from 870 leaves us with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Let's proceed to step 10:
357 goes into 1560 4 times with a remainder of 132.
Use 4 as the next digit of our solution. 
Result so far: 78435.24
If we subtract 1428 from 1560, we get 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Moving on to step 11:
The number 357 fits into 1320 3 times, leaving a remainder of 249.
The next digit of our result is 3. 
Result so far: 78435.243
If we subtract 1071 from 1320, we get 249.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2490, and continue the process.

Advancing to step 12:
If we divide 2490 by 357, we get 6 and a remainder of 348.
The number 6 becomes the next digit in our result. 
Result so far: 78435.2436
Deduct 2142 from 2490 and we're left with 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Moving on to step 13:
The number 357 fits into 3480 9 times, leaving a remainder of 267.
Record the quotient 9 as the next digit in the result. 
Result so far: 78435.24369
The remainder is 267 after subtracting 3213 from 3480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2670, and continue the process.

Going ahead to step 14:
357 can be fit into 2670 7 times, resulting in a remainder of 171.
Use 7 as the next digit of our solution. 
Result so far: 78435.243697
Subtracting 2499 from 2670 leaves us with 171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

Going ahead to step 15:
If we divide 1710 by 357, we get 4 and a remainder of 282.
Put 4 as the next digit of the answer. 
Result so far: 78435.2436974
Subtract 1428 from 1710 to get 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

On to step 16:
357 goes into 2820 7 times with a remainder of 321.
Put 7 as the next digit of the answer. 
Result so far: 78435.24369747
Subtracting 2499 from 2820 leaves us with 321.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3210, and continue the process.

In conclusion, the division gives 78435.24369747 with a balance of 3.21e-07.
