We're dividing 71309343 by 348 
The aim is to understand the frequency of 348 in 71309343.

Going ahead to step 1:
If we divide 7 by 348, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 348

Moving on to step 2:
When dividing 71 by 348, we get 0 with a remainder of 71.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 71, we get 71.
Grab the next digit (3) from the dividend, add it to 71, then carry on: 713 / 348

Advancing to step 3:
713 divided by 348 is 2 with a remainder of 17.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 696 from 713, we get 17.
Include the next digit (0) from the dividend after 17, then repeat: 170 / 348

Let's proceed to step 4:
The number 348 fits into 170 0 times, leaving a remainder of 170.
Put 0 as the next digit of the answer. 
Result so far: 20.0
If we subtract 0 from 170, we get 170.
Take the next digit (9) from the dividend and append it to 170, then repeat: 1709 / 348

Advancing to step 5:
When dividing 1709 by 348, we get 4 with a remainder of 317.
The number 4 becomes the next digit in our result. 
Result so far: 204.0
If we take 1392 away from 1709, we end up with 317.
Take the next digit (3) from the dividend and append it to 317, then repeat: 3173 / 348

Moving on to step 6:
348 goes into 3173 9 times with a remainder of 41.
The next digit of our result is 9. 
Result so far: 2049.0
Deduct 3132 from 3173 and we're left with 41.
Bring next digit (4) of the dividend behind the 41 and repeat the process: 414 / 348

Step 7:
The number 348 fits into 414 1 times, leaving a remainder of 66.
Use 1 as the next digit of our solution. 
Result so far: 20491.0
Subtract 348 from 414 to get 66.
Grab the next digit (3) from the dividend, add it to 66, then carry on: 663 / 348

Moving on to step 8:
The number 348 fits into 663 1 times, leaving a remainder of 315.
Use 1 as the next digit of our solution. 
Result so far: 204911.0
If we subtract 348 from 663, we get 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

Going ahead to step 9:
If we divide 3150 by 348, we get 9 and a remainder of 18.
Use 9 as the next digit of our solution. 
Result so far: 204911.9
The remainder is 18 after subtracting 3132 from 3150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 10:
When dividing 180 by 348, we get 0 with a remainder of 180.
Use 0 as the next digit of our solution. 
Result so far: 204911.9
If we subtract 0 from 180, we get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Advancing to step 11:
The number 348 fits into 1800 5 times, leaving a remainder of 60.
Record the quotient 5 as the next digit in the result. 
Result so far: 204911.905
Deduct 1740 from 1800 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 12:
The number 348 fits into 600 1 times, leaving a remainder of 252.
Record the quotient 1 as the next digit in the result. 
Result so far: 204911.9051
If we take 348 away from 600, we end up with 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Moving on to step 13:
348 goes into 2520 7 times with a remainder of 84.
Record the quotient 7 as the next digit in the result. 
Result so far: 204911.90517
The remainder is 84 after subtracting 2436 from 2520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Step 14:
348 can be fit into 840 2 times, resulting in a remainder of 144.
The number 2 becomes the next digit in our result. 
Result so far: 204911.905172
If we take 696 away from 840, we end up with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Moving on to step 15:
The number 348 fits into 1440 4 times, leaving a remainder of 48.
The number 4 becomes the next digit in our result. 
Result so far: 204911.9051724
The remainder is 48 after subtracting 1392 from 1440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 16:
When dividing 480 by 348, we get 1 with a remainder of 132.
Put 1 as the next digit of the answer. 
Result so far: 204911.90517241
Subtract 348 from 480 to get 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

The quotient of the division is 204911.90517241, and the remainder is 1.32e-07.
