We look at the division of 64442234 by 353 
The aim is to understand the frequency of 353 in 64442234.

Advancing to step 1:
6 divided by 353 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 353

Advancing to step 2:
When dividing 64 by 353, we get 0 with a remainder of 64.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 64 leaves us with 64.
Include the next digit (4) from the dividend after 64, then repeat: 644 / 353

Going ahead to step 3:
When dividing 644 by 353, we get 1 with a remainder of 291.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 353 away from 644, we end up with 291.
Grab the next digit (4) from the dividend, add it to 291, then carry on: 2914 / 353

Let's proceed to step 4:
2914 divided by 353 is 8 with a remainder of 90.
Put 8 as the next digit of the answer. 
Result so far: 18.0
If we subtract 2824 from 2914, we get 90.
Fetch the next digit (2) from the dividend, attach it to 90 and continue: 902 / 353

Step 5:
The number 353 fits into 902 2 times, leaving a remainder of 196.
The number 2 becomes the next digit in our result. 
Result so far: 182.0
Subtracting 706 from 902 leaves us with 196.
Include the next digit (2) from the dividend after 196, then repeat: 1962 / 353

Let's proceed to step 6:
353 goes into 1962 5 times with a remainder of 197.
Put 5 as the next digit of the answer. 
Result so far: 1825.0
Subtracting 1765 from 1962 leaves us with 197.
Bring next digit (3) of the dividend behind the 197 and repeat the process: 1973 / 353

Going ahead to step 7:
353 goes into 1973 5 times with a remainder of 208.
The number 5 becomes the next digit in our result. 
Result so far: 18255.0
If we take 1765 away from 1973, we end up with 208.
Append the next digit (4) from the dividend to 208 and continue with: 2084 / 353

On to step 8:
353 can be fit into 2084 5 times, resulting in a remainder of 319.
Put 5 as the next digit of the answer. 
Result so far: 182555.0
If we take 1765 away from 2084, we end up with 319.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3190, and continue the process.

Moving on to step 9:
353 can be fit into 3190 9 times, resulting in a remainder of 13.
The next digit of our result is 9. 
Result so far: 182555.9
Subtract 3177 from 3190 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 10:
353 goes into 130 0 times with a remainder of 130.
Write down 0 as next digit of the result. 
Result so far: 182555.9
Subtract 0 from 130 to get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Step 11:
The number 353 fits into 1300 3 times, leaving a remainder of 241.
Put 3 as the next digit of the answer. 
Result so far: 182555.903
If we subtract 1059 from 1300, we get 241.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2410, and continue the process.

On to step 12:
If we divide 2410 by 353, we get 6 and a remainder of 292.
Record the quotient 6 as the next digit in the result. 
Result so far: 182555.9036
If we take 2118 away from 2410, we end up with 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Step 13:
353 can be fit into 2920 8 times, resulting in a remainder of 96.
The next digit of our result is 8. 
Result so far: 182555.90368
Subtract 2824 from 2920 to get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Let's proceed to step 14:
If we divide 960 by 353, we get 2 and a remainder of 254.
Use 2 as the next digit of our solution. 
Result so far: 182555.903682
If we subtract 706 from 960, we get 254.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

Let's proceed to step 15:
2540 divided by 353 is 7 with a remainder of 69.
Put 7 as the next digit of the answer. 
Result so far: 182555.9036827
If we take 2471 away from 2540, we end up with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Step 16:
When dividing 690 by 353, we get 1 with a remainder of 337.
Write down 1 as next digit of the result. 
Result so far: 182555.90368271
Subtracting 353 from 690 leaves us with 337.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3370, and continue the process.

After the division, we end up with 182555.90368271 and a remainder of 3.37e-07.
