We look at the division of 78628472 by 348 
The aim is to understand the frequency of 348 in 78628472.

Moving on to step 1:
7 divided by 348 is 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 348

Moving on to step 2:
When dividing 78 by 348, we get 0 with a remainder of 78.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 78 to get 78.
Grab the next digit (6) from the dividend, add it to 78, then carry on: 786 / 348

On to step 3:
If we divide 786 by 348, we get 2 and a remainder of 90.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 696 from 786, we get 90.
Append the next digit (2) from the dividend to 90 and continue with: 902 / 348

Advancing to step 4:
If we divide 902 by 348, we get 2 and a remainder of 206.
Put 2 as the next digit of the answer. 
Result so far: 22.0
Deduct 696 from 902 and we're left with 206.
Include the next digit (8) from the dividend after 206, then repeat: 2068 / 348

On to step 5:
348 can be fit into 2068 5 times, resulting in a remainder of 328.
Record the quotient 5 as the next digit in the result. 
Result so far: 225.0
If we take 1740 away from 2068, we end up with 328.
Take the next digit (4) from the dividend and append it to 328, then repeat: 3284 / 348

On to step 6:
3284 divided by 348 is 9 with a remainder of 152.
Use 9 as the next digit of our solution. 
Result so far: 2259.0
Subtract 3132 from 3284 to get 152.
Append the next digit (7) from the dividend to 152 and continue with: 1527 / 348

Moving on to step 7:
348 goes into 1527 4 times with a remainder of 135.
Record the quotient 4 as the next digit in the result. 
Result so far: 22594.0
Subtract 1392 from 1527 to get 135.
Fetch the next digit (2) from the dividend, attach it to 135 and continue: 1352 / 348

Step 8:
The number 348 fits into 1352 3 times, leaving a remainder of 308.
Use 3 as the next digit of our solution. 
Result so far: 225943.0
Subtracting 1044 from 1352 leaves us with 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Advancing to step 9:
348 goes into 3080 8 times with a remainder of 296.
The next digit of our result is 8. 
Result so far: 225943.8
Deduct 2784 from 3080 and we're left with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Let's proceed to step 10:
348 goes into 2960 8 times with a remainder of 176.
Record the quotient 8 as the next digit in the result. 
Result so far: 225943.88
Subtracting 2784 from 2960 leaves us with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

The final outcome is 225943.88, with a leftover of 0.176.
