Let's divide 69918153 by 343
The aim is to understand the frequency of 343 in 69918153.

Let's proceed to step 1:
If we divide 6 by 343, we get 0 and a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (9) from the dividend and append it to 6, then repeat: 69 / 343

Step 2:
69 divided by 343 is 0 with a remainder of 69.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 69 leaves us with 69.
Take the next digit (9) from the dividend and append it to 69, then repeat: 699 / 343

Let's proceed to step 3:
343 goes into 699 2 times with a remainder of 13.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 686 from 699 and we're left with 13.
Fetch the next digit (1) from the dividend, attach it to 13 and continue: 131 / 343

Moving on to step 4:
If we divide 131 by 343, we get 0 and a remainder of 131.
Use 0 as the next digit of our solution. 
Result so far: 20.0
Subtracting 0 from 131 leaves us with 131.
Bring next digit (8) of the dividend behind the 131 and repeat the process: 1318 / 343

Step 5:
If we divide 1318 by 343, we get 3 and a remainder of 289.
The number 3 becomes the next digit in our result. 
Result so far: 203.0
If we subtract 1029 from 1318, we get 289.
Append the next digit (1) from the dividend to 289 and continue with: 2891 / 343

On to step 6:
The number 343 fits into 2891 8 times, leaving a remainder of 147.
Use 8 as the next digit of our solution. 
Result so far: 2038.0
The remainder is 147 after subtracting 2744 from 2891.
Bring next digit (5) of the dividend behind the 147 and repeat the process: 1475 / 343

Step 7:
If we divide 1475 by 343, we get 4 and a remainder of 103.
Put 4 as the next digit of the answer. 
Result so far: 20384.0
The remainder is 103 after subtracting 1372 from 1475.
Take the next digit (3) from the dividend and append it to 103, then repeat: 1033 / 343

Advancing to step 8:
343 can be fit into 1033 3 times, resulting in a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 203843.0
Deduct 1029 from 1033 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 9:
343 goes into 40 0 times with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 203843.0
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 10:
343 can be fit into 400 1 times, resulting in a remainder of 57.
Put 1 as the next digit of the answer. 
Result so far: 203843.01
Subtract 343 from 400 to get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

On to step 11:
When dividing 570 by 343, we get 1 with a remainder of 227.
The number 1 becomes the next digit in our result. 
Result so far: 203843.011
Subtract 343 from 570 to get 227.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2270, and continue the process.

Our division results in 203843.011 with a remaining 0.0227.
