We look at the division of 29584348 by 348 
The aim is to understand the frequency of 348 in 29584348.

Step 1:
The number 348 fits into 2 0 times, leaving a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 348

Let's proceed to step 2:
If we divide 29 by 348, we get 0 and a remainder of 29.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 29, we get 29.
Include the next digit (5) from the dividend after 29, then repeat: 295 / 348

Let's proceed to step 3:
The number 348 fits into 295 0 times, leaving a remainder of 295.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 295 leaves us with 295.
Take the next digit (8) from the dividend and append it to 295, then repeat: 2958 / 348

Going ahead to step 4:
If we divide 2958 by 348, we get 8 and a remainder of 174.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we take 2784 away from 2958, we end up with 174.
Take the next digit (4) from the dividend and append it to 174, then repeat: 1744 / 348

Going ahead to step 5:
348 goes into 1744 5 times with a remainder of 4.
Put 5 as the next digit of the answer. 
Result so far: 85.0
If we subtract 1740 from 1744, we get 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 348

On to step 6:
If we divide 43 by 348, we get 0 and a remainder of 43.
The next digit of our result is 0. 
Result so far: 850.0
Subtract 0 from 43 to get 43.
Bring next digit (4) of the dividend behind the 43 and repeat the process: 434 / 348

Going ahead to step 7:
When dividing 434 by 348, we get 1 with a remainder of 86.
The number 1 becomes the next digit in our result. 
Result so far: 8501.0
Subtract 348 from 434 to get 86.
Append the next digit (8) from the dividend to 86 and continue with: 868 / 348

Going ahead to step 8:
348 goes into 868 2 times with a remainder of 172.
The next digit of our result is 2. 
Result so far: 85012.0
If we take 696 away from 868, we end up with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Going ahead to step 9:
1720 divided by 348 is 4 with a remainder of 328.
Record the quotient 4 as the next digit in the result. 
Result so far: 85012.4
Subtract 1392 from 1720 to get 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Moving on to step 10:
When dividing 3280 by 348, we get 9 with a remainder of 148.
Record the quotient 9 as the next digit in the result. 
Result so far: 85012.49
If we take 3132 away from 3280, we end up with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

On to step 11:
348 can be fit into 1480 4 times, resulting in a remainder of 88.
Write down 4 as next digit of the result. 
Result so far: 85012.494
Deduct 1392 from 1480 and we're left with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Going ahead to step 12:
When dividing 880 by 348, we get 2 with a remainder of 184.
The next digit of our result is 2. 
Result so far: 85012.4942
The remainder is 184 after subtracting 696 from 880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

On to step 13:
The number 348 fits into 1840 5 times, leaving a remainder of 100.
Put 5 as the next digit of the answer. 
Result so far: 85012.49425
Deduct 1740 from 1840 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Step 14:
The number 348 fits into 1000 2 times, leaving a remainder of 304.
The next digit of our result is 2. 
Result so far: 85012.494252
Subtracting 696 from 1000 leaves us with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Let's proceed to step 15:
If we divide 3040 by 348, we get 8 and a remainder of 256.
The number 8 becomes the next digit in our result. 
Result so far: 85012.4942528
Subtracting 2784 from 3040 leaves us with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

On to step 16:
2560 divided by 348 is 7 with a remainder of 124.
Use 7 as the next digit of our solution. 
Result so far: 85012.49425287
Subtracting 2436 from 2560 leaves us with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

The final result is 85012.49425287 with a remainder of 1.24e-07.
