Let's divide 66901263 by 348
The aim is to understand the frequency of 348 in 66901263.

Going ahead to step 1:
348 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 348

Step 2:
66 divided by 348 is 0 with a remainder of 66.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 66 and we're left with 66.
Fetch the next digit (9) from the dividend, attach it to 66 and continue: 669 / 348

Let's proceed to step 3:
348 goes into 669 1 times with a remainder of 321.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 321 after subtracting 348 from 669.
Fetch the next digit (0) from the dividend, attach it to 321 and continue: 3210 / 348

Step 4:
3210 divided by 348 is 9 with a remainder of 78.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
Deduct 3132 from 3210 and we're left with 78.
Include the next digit (1) from the dividend after 78, then repeat: 781 / 348

Going ahead to step 5:
348 can be fit into 781 2 times, resulting in a remainder of 85.
Put 2 as the next digit of the answer. 
Result so far: 192.0
Subtract 696 from 781 to get 85.
Bring next digit (2) of the dividend behind the 85 and repeat the process: 852 / 348

Advancing to step 6:
852 divided by 348 is 2 with a remainder of 156.
The number 2 becomes the next digit in our result. 
Result so far: 1922.0
If we subtract 696 from 852, we get 156.
Bring next digit (6) of the dividend behind the 156 and repeat the process: 1566 / 348

Step 7:
348 goes into 1566 4 times with a remainder of 174.
Write down 4 as next digit of the result. 
Result so far: 19224.0
Subtract 1392 from 1566 to get 174.
Fetch the next digit (3) from the dividend, attach it to 174 and continue: 1743 / 348

Going ahead to step 8:
348 goes into 1743 5 times with a remainder of 3.
The next digit of our result is 5. 
Result so far: 192245.0
If we take 1740 away from 1743, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 9:
The number 348 fits into 30 0 times, leaving a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 192245.0
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 10:
When dividing 300 by 348, we get 0 with a remainder of 300.
Use 0 as the next digit of our solution. 
Result so far: 192245.0
The remainder is 300 after subtracting 0 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

The final outcome is 192245.0, with a leftover of 0.3.
