We look at the division of 75516002 by 343 
The aim is to understand the frequency of 343 in 75516002.

Step 1:
The number 343 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Take the next digit (5) from the dividend and append it to 7, then repeat: 75 / 343

Going ahead to step 2:
If we divide 75 by 343, we get 0 and a remainder of 75.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 75, we get 75.
Fetch the next digit (5) from the dividend, attach it to 75 and continue: 755 / 343

Going ahead to step 3:
The number 343 fits into 755 2 times, leaving a remainder of 69.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 686 from 755, we get 69.
Grab the next digit (1) from the dividend, add it to 69, then carry on: 691 / 343

Moving on to step 4:
343 can be fit into 691 2 times, resulting in a remainder of 5.
The number 2 becomes the next digit in our result. 
Result so far: 22.0
If we take 686 away from 691, we end up with 5.
Grab the next digit (6) from the dividend, add it to 5, then carry on: 56 / 343

On to step 5:
56 divided by 343 is 0 with a remainder of 56.
The number 0 becomes the next digit in our result. 
Result so far: 220.0
Deduct 0 from 56 and we're left with 56.
Take the next digit (0) from the dividend and append it to 56, then repeat: 560 / 343

Going ahead to step 6:
560 divided by 343 is 1 with a remainder of 217.
Put 1 as the next digit of the answer. 
Result so far: 2201.0
Subtract 343 from 560 to get 217.
Grab the next digit (0) from the dividend, add it to 217, then carry on: 2170 / 343

Step 7:
When dividing 2170 by 343, we get 6 with a remainder of 112.
Put 6 as the next digit of the answer. 
Result so far: 22016.0
Subtracting 2058 from 2170 leaves us with 112.
Take the next digit (2) from the dividend and append it to 112, then repeat: 1122 / 343

Step 8:
343 can be fit into 1122 3 times, resulting in a remainder of 93.
The next digit of our result is 3. 
Result so far: 220163.0
Subtracting 1029 from 1122 leaves us with 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

Going ahead to step 9:
When dividing 930 by 343, we get 2 with a remainder of 244.
Put 2 as the next digit of the answer. 
Result so far: 220163.2
Subtracting 686 from 930 leaves us with 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

On to step 10:
The number 343 fits into 2440 7 times, leaving a remainder of 39.
The next digit of our result is 7. 
Result so far: 220163.27
Subtract 2401 from 2440 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Advancing to step 11:
390 divided by 343 is 1 with a remainder of 47.
Record the quotient 1 as the next digit in the result. 
Result so far: 220163.271
Subtracting 343 from 390 leaves us with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Going ahead to step 12:
When dividing 470 by 343, we get 1 with a remainder of 127.
The next digit of our result is 1. 
Result so far: 220163.2711
The remainder is 127 after subtracting 343 from 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

The quotient of the division is 220163.2711, and the remainder is 0.00127.
