We look at the division of 18722201 by 348 
The aim is to understand the frequency of 348 in 18722201.

Moving on to step 1:
When dividing 1 by 348, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 348

On to step 2:
348 goes into 18 0 times with a remainder of 18.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 18 after subtracting 0 from 18.
Fetch the next digit (7) from the dividend, attach it to 18 and continue: 187 / 348

Advancing to step 3:
348 can be fit into 187 0 times, resulting in a remainder of 187.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 187 leaves us with 187.
Take the next digit (2) from the dividend and append it to 187, then repeat: 1872 / 348

Advancing to step 4:
If we divide 1872 by 348, we get 5 and a remainder of 132.
The next digit of our result is 5. 
Result so far: 5.0
Subtracting 1740 from 1872 leaves us with 132.
Fetch the next digit (2) from the dividend, attach it to 132 and continue: 1322 / 348

Let's proceed to step 5:
If we divide 1322 by 348, we get 3 and a remainder of 278.
The next digit of our result is 3. 
Result so far: 53.0
If we subtract 1044 from 1322, we get 278.
Grab the next digit (2) from the dividend, add it to 278, then carry on: 2782 / 348

On to step 6:
2782 divided by 348 is 7 with a remainder of 346.
The next digit of our result is 7. 
Result so far: 537.0
If we take 2436 away from 2782, we end up with 346.
Take the next digit (0) from the dividend and append it to 346, then repeat: 3460 / 348

On to step 7:
3460 divided by 348 is 9 with a remainder of 328.
The next digit of our result is 9. 
Result so far: 5379.0
If we subtract 3132 from 3460, we get 328.
Bring next digit (1) of the dividend behind the 328 and repeat the process: 3281 / 348

Step 8:
The number 348 fits into 3281 9 times, leaving a remainder of 149.
The next digit of our result is 9. 
Result so far: 53799.0
Subtracting 3132 from 3281 leaves us with 149.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

Let's proceed to step 9:
348 can be fit into 1490 4 times, resulting in a remainder of 98.
Put 4 as the next digit of the answer. 
Result so far: 53799.4
Subtracting 1392 from 1490 leaves us with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Going ahead to step 10:
The number 348 fits into 980 2 times, leaving a remainder of 284.
Record the quotient 2 as the next digit in the result. 
Result so far: 53799.42
Deduct 696 from 980 and we're left with 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Let's proceed to step 11:
The number 348 fits into 2840 8 times, leaving a remainder of 56.
Put 8 as the next digit of the answer. 
Result so far: 53799.428
If we take 2784 away from 2840, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 12:
348 goes into 560 1 times with a remainder of 212.
Use 1 as the next digit of our solution. 
Result so far: 53799.4281
Subtract 348 from 560 to get 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

On to step 13:
When dividing 2120 by 348, we get 6 with a remainder of 32.
The next digit of our result is 6. 
Result so far: 53799.42816
If we subtract 2088 from 2120, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 14:
When dividing 320 by 348, we get 0 with a remainder of 320.
Use 0 as the next digit of our solution. 
Result so far: 53799.42816
If we subtract 0 from 320, we get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Let's proceed to step 15:
3200 divided by 348 is 9 with a remainder of 68.
Use 9 as the next digit of our solution. 
Result so far: 53799.4281609
Subtract 3132 from 3200 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 16:
If we divide 680 by 348, we get 1 and a remainder of 332.
Use 1 as the next digit of our solution. 
Result so far: 53799.42816091
Subtracting 348 from 680 leaves us with 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

The final outcome is 53799.42816091, with a leftover of 3.32e-07.
