Let's divide 28613640 by 353
The aim is to understand the frequency of 353 in 28613640.

Step 1:
353 goes into 2 0 times with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 353

Let's proceed to step 2:
353 can be fit into 28 0 times, resulting in a remainder of 28.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 28, we end up with 28.
Append the next digit (6) from the dividend to 28 and continue with: 286 / 353

Going ahead to step 3:
The number 353 fits into 286 0 times, leaving a remainder of 286.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 286, we end up with 286.
Grab the next digit (1) from the dividend, add it to 286, then carry on: 2861 / 353

Moving on to step 4:
If we divide 2861 by 353, we get 8 and a remainder of 37.
Put 8 as the next digit of the answer. 
Result so far: 8.0
The remainder is 37 after subtracting 2824 from 2861.
Fetch the next digit (3) from the dividend, attach it to 37 and continue: 373 / 353

Let's proceed to step 5:
If we divide 373 by 353, we get 1 and a remainder of 20.
The number 1 becomes the next digit in our result. 
Result so far: 81.0
Deduct 353 from 373 and we're left with 20.
Include the next digit (6) from the dividend after 20, then repeat: 206 / 353

Step 6:
353 can be fit into 206 0 times, resulting in a remainder of 206.
Write down 0 as next digit of the result. 
Result so far: 810.0
Subtract 0 from 206 to get 206.
Append the next digit (4) from the dividend to 206 and continue with: 2064 / 353

Let's proceed to step 7:
The number 353 fits into 2064 5 times, leaving a remainder of 299.
The next digit of our result is 5. 
Result so far: 8105.0
Deduct 1765 from 2064 and we're left with 299.
Include the next digit (0) from the dividend after 299, then repeat: 2990 / 353

Let's proceed to step 8:
2990 divided by 353 is 8 with a remainder of 166.
Record the quotient 8 as the next digit in the result. 
Result so far: 81058.0
If we subtract 2824 from 2990, we get 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Step 9:
If we divide 1660 by 353, we get 4 and a remainder of 248.
Use 4 as the next digit of our solution. 
Result so far: 81058.4
The remainder is 248 after subtracting 1412 from 1660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Moving on to step 10:
353 can be fit into 2480 7 times, resulting in a remainder of 9.
Write down 7 as next digit of the result. 
Result so far: 81058.47
If we subtract 2471 from 2480, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 11:
353 can be fit into 90 0 times, resulting in a remainder of 90.
The next digit of our result is 0. 
Result so far: 81058.47
The remainder is 90 after subtracting 0 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Moving on to step 12:
900 divided by 353 is 2 with a remainder of 194.
The next digit of our result is 2. 
Result so far: 81058.4702
Deduct 706 from 900 and we're left 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.

Moving on to step 13:
If we divide 1940 by 353, we get 5 and a remainder of 175.
Use 5 as the next digit of our solution. 
Result so far: 81058.47025
Subtract 1765 from 1940 to get 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Advancing to step 14:
353 can be fit into 1750 4 times, resulting in a remainder of 338.
Record the quotient 4 as the next digit in the result. 
Result so far: 81058.470254
Subtracting 1412 from 1750 leaves us with 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

Let's proceed to step 15:
353 can be fit into 3380 9 times, resulting in a remainder of 203.
The number 9 becomes the next digit in our result. 
Result so far: 81058.4702549
Subtracting 3177 from 3380 leaves us with 203.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2030, and continue the process.

Advancing to step 16:
The number 353 fits into 2030 5 times, leaving a remainder of 265.
Put 5 as the next digit of the answer. 
Result so far: 81058.47025495
Subtract 1765 from 2030 to get 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

After the division, we end up with 81058.47025495 and a remainder of 2.65e-07.
