We're dividing 75179115 by 343 
The aim is to understand the frequency of 343 in 75179115.

Going ahead to step 1:
When dividing 7 by 343, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Fetch the next digit (5) from the dividend, attach it to 7 and continue: 75 / 343

Step 2:
When dividing 75 by 343, we get 0 with a remainder of 75.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 75 leaves us with 75.
Append the next digit (1) from the dividend to 75 and continue with: 751 / 343

Advancing to step 3:
The number 343 fits into 751 2 times, leaving a remainder of 65.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 65 after subtracting 686 from 751.
Grab the next digit (7) from the dividend, add it to 65, then carry on: 657 / 343

Moving on to step 4:
657 divided by 343 is 1 with a remainder of 314.
Write down 1 as next digit of the result. 
Result so far: 21.0
The remainder is 314 after subtracting 343 from 657.
Include the next digit (9) from the dividend after 314, then repeat: 3149 / 343

Step 5:
343 goes into 3149 9 times with a remainder of 62.
Record the quotient 9 as the next digit in the result. 
Result so far: 219.0
Subtracting 3087 from 3149 leaves us with 62.
Fetch the next digit (1) from the dividend, attach it to 62 and continue: 621 / 343

Advancing to step 6:
The number 343 fits into 621 1 times, leaving a remainder of 278.
Write down 1 as next digit of the result. 
Result so far: 2191.0
Subtract 343 from 621 to get 278.
Grab the next digit (1) from the dividend, add it to 278, then carry on: 2781 / 343

Moving on to step 7:
2781 divided by 343 is 8 with a remainder of 37.
Write down 8 as next digit of the result. 
Result so far: 21918.0
Subtracting 2744 from 2781 leaves us with 37.
Grab the next digit (5) from the dividend, add it to 37, then carry on: 375 / 343

Going ahead to step 8:
If we divide 375 by 343, we get 1 and a remainder of 32.
Use 1 as the next digit of our solution. 
Result so far: 219181.0
Deduct 343 from 375 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.

Moving on to step 9:
The number 343 fits into 320 0 times, leaving a remainder of 320.
Put 0 as the next digit of the answer. 
Result so far: 219181.0
The remainder is 320 after subtracting 0 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Going ahead to step 10:
3200 divided by 343 is 9 with a remainder of 113.
Record the quotient 9 as the next digit in the result. 
Result so far: 219181.09
The remainder is 113 after subtracting 3087 from 3200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

Moving on to step 11:
343 goes into 1130 3 times with a remainder of 101.
Put 3 as the next digit of the answer. 
Result so far: 219181.093
If we take 1029 away from 1130, we end up with 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

Step 12:
When dividing 1010 by 343, we get 2 with a remainder of 324.
The number 2 becomes the next digit in our result. 
Result so far: 219181.0932
Deduct 686 from 1010 and we're left with 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

Moving on to step 13:
If we divide 3240 by 343, we get 9 and a remainder of 153.
Use 9 as the next digit of our solution. 
Result so far: 219181.09329
Subtracting 3087 from 3240 leaves us with 153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

On to step 14:
The number 343 fits into 1530 4 times, leaving a remainder of 158.
Put 4 as the next digit of the answer. 
Result so far: 219181.093294
Subtract 1372 from 1530 to get 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Going ahead to step 15:
The number 343 fits into 1580 4 times, leaving a remainder of 208.
Use 4 as the next digit of our solution. 
Result so far: 219181.0932944
Deduct 1372 from 1580 and we're left with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

The final result is 219181.0932944 with a remainder of 2.08e-06.
