We divide 8665593 by 353
The aim is to understand the frequency of 353 in 8665593.

Let's proceed to step 1:
8 divided by 353 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 353

Step 2:
353 goes into 86 0 times with a remainder of 86.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 86 and we're left with 86.
Grab the next digit (6) from the dividend, add it to 86, then carry on: 866 / 353

On to step 3:
866 divided by 353 is 2 with a remainder of 160.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 706 from 866, we get 160.
Include the next digit (5) from the dividend after 160, then repeat: 1605 / 353

Let's proceed to step 4:
The number 353 fits into 1605 4 times, leaving a remainder of 193.
Use 4 as the next digit of our solution. 
Result so far: 24.0
The remainder is 193 after subtracting 1412 from 1605.
Fetch the next digit (5) from the dividend, attach it to 193 and continue: 1935 / 353

Step 5:
The number 353 fits into 1935 5 times, leaving a remainder of 170.
Write down 5 as next digit of the result. 
Result so far: 245.0
Deduct 1765 from 1935 and we're left with 170.
Append the next digit (9) from the dividend to 170 and continue with: 1709 / 353

Step 6:
353 can be fit into 1709 4 times, resulting in a remainder of 297.
Record the quotient 4 as the next digit in the result. 
Result so far: 2454.0
The remainder is 297 after subtracting 1412 from 1709.
Fetch the next digit (3) from the dividend, attach it to 297 and continue: 2973 / 353

Step 7:
2973 divided by 353 is 8 with a remainder of 149.
Use 8 as the next digit of our solution. 
Result so far: 24548.0
Deduct 2824 from 2973 and we're left with 149.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

Advancing to step 8:
When dividing 1490 by 353, we get 4 with a remainder of 78.
The number 4 becomes the next digit in our result. 
Result so far: 24548.4
Subtracting 1412 from 1490 leaves us with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Advancing to step 9:
If we divide 780 by 353, we get 2 and a remainder of 74.
Put 2 as the next digit of the answer. 
Result so far: 24548.42
Subtract 706 from 780 to get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Step 10:
The number 353 fits into 740 2 times, leaving a remainder of 34.
Record the quotient 2 as the next digit in the result. 
Result so far: 24548.422
Deduct 706 from 740 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

The final result is 24548.422 with a remainder of 0.0034.
