We look at the division of 8345600 by 352 
The aim is to understand the frequency of 352 in 8345600.

Let's proceed to step 1:
The number 352 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (3) of the dividend behind the 8 and repeat the process: 83 / 352

Step 2:
352 can be fit into 83 0 times, resulting in a remainder of 83.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 83, we end up with 83.
Include the next digit (4) from the dividend after 83, then repeat: 834 / 352

Going ahead to step 3:
The number 352 fits into 834 2 times, leaving a remainder of 130.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 704 from 834 and we're left with 130.
Take the next digit (5) from the dividend and append it to 130, then repeat: 1305 / 352

Moving on to step 4:
352 can be fit into 1305 3 times, resulting in a remainder of 249.
Record the quotient 3 as the next digit in the result. 
Result so far: 23.0
Subtract 1056 from 1305 to get 249.
Include the next digit (6) from the dividend after 249, then repeat: 2496 / 352

Going ahead to step 5:
2496 divided by 352 is 7 with a remainder of 32.
The number 7 becomes the next digit in our result. 
Result so far: 237.0
If we take 2464 away from 2496, we end up with 32.
Append the next digit (0) from the dividend to 32 and continue with: 320 / 352

Step 6:
If we divide 320 by 352, we get 0 and a remainder of 320.
Write down 0 as next digit of the result. 
Result so far: 2370.0
Subtracting 0 from 320 leaves us with 320.
Fetch the next digit (0) from the dividend, attach it to 320 and continue: 3200 / 352

Step 7:
352 goes into 3200 9 times with a remainder of 32.
The number 9 becomes the next digit in our result. 
Result so far: 23709.0
Deduct 3168 from 3200 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 8:
If we divide 320 by 352, we get 0 and a remainder of 320.
Use 0 as the next digit of our solution. 
Result so far: 23709.0
If we subtract 0 from 320, we get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Let's proceed to step 9:
352 can be fit into 3200 9 times, resulting in a remainder of 32.
The next digit of our result is 9. 
Result so far: 23709.09
Subtracting 3168 from 3200 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 10:
320 divided by 352 is 0 with a remainder of 320.
Record the quotient 0 as the next digit in the result. 
Result so far: 23709.09
If we subtract 0 from 320, we get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

On to step 11:
If we divide 3200 by 352, we get 9 and a remainder of 32.
Put 9 as the next digit of the answer. 
Result so far: 23709.0909
If we take 3168 away from 3200, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 12:
352 goes into 320 0 times with a remainder of 320.
Use 0 as the next digit of our solution. 
Result so far: 23709.0909
If we subtract 0 from 320, we get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Advancing to step 13:
352 goes into 3200 9 times with a remainder of 32.
Put 9 as the next digit of the answer. 
Result so far: 23709.090909
The remainder is 32 after subtracting 3168 from 3200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 14:
352 can be fit into 320 0 times, resulting in a remainder of 320.
Put 0 as the next digit of the answer. 
Result so far: 23709.090909
If we take 0 away from 320, we end up with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Advancing to step 15:
If we divide 3200 by 352, we get 9 and a remainder of 32.
Use 9 as the next digit of our solution. 
Result so far: 23709.09090909
If we take 3168 away from 3200, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

After the division, we end up with 23709.09090909 and a remainder of 3.2e-08.
