We're dividing 48690564 by 312 
The aim is to understand the frequency of 312 in 48690564.

Let's proceed to step 1:
If we divide 4 by 312, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Take the next digit (8) from the dividend and append it to 4, then repeat: 48 / 312

Going ahead to step 2:
When dividing 48 by 312, we get 0 with a remainder of 48.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 48 and we're left with 48.
Append the next digit (6) from the dividend to 48 and continue with: 486 / 312

Moving on to step 3:
312 can be fit into 486 1 times, resulting in a remainder of 174.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 312 away from 486, we end up with 174.
Bring next digit (9) of the dividend behind the 174 and repeat the process: 1749 / 312

Step 4:
When dividing 1749 by 312, we get 5 with a remainder of 189.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Subtracting 1560 from 1749 leaves us with 189.
Include the next digit (0) from the dividend after 189, then repeat: 1890 / 312

Going ahead to step 5:
312 can be fit into 1890 6 times, resulting in a remainder of 18.
Put 6 as the next digit of the answer. 
Result so far: 156.0
Subtracting 1872 from 1890 leaves us with 18.
Append the next digit (5) from the dividend to 18 and continue with: 185 / 312

Let's proceed to step 6:
The number 312 fits into 185 0 times, leaving a remainder of 185.
Put 0 as the next digit of the answer. 
Result so far: 1560.0
Deduct 0 from 185 and we're left with 185.
Include the next digit (6) from the dividend after 185, then repeat: 1856 / 312

Advancing to step 7:
312 can be fit into 1856 5 times, resulting in a remainder of 296.
Use 5 as the next digit of our solution. 
Result so far: 15605.0
Subtract 1560 from 1856 to get 296.
Include the next digit (4) from the dividend after 296, then repeat: 2964 / 312

Moving on to step 8:
When dividing 2964 by 312, we get 9 with a remainder of 156.
The next digit of our result is 9. 
Result so far: 156059.0
Deduct 2808 from 2964 and we're left with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Let's proceed to step 9:
312 goes into 1560 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 156059.5
If we subtract 1560 from 1560, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 10:
The number 312 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 156059.5
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 11:
312 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 156059.5
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 156059.5, with a leftover of 0.0.
