Let's divide 48396575 by 312
The aim is to understand the frequency of 312 in 48396575.

Let's proceed to step 1:
When dividing 4 by 312, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
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

Let's proceed to step 2:
When dividing 48 by 312, we get 0 with a remainder of 48.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 48, we end up with 48.
Grab the next digit (3) from the dividend, add it to 48, then carry on: 483 / 312

Let's proceed to step 3:
If we divide 483 by 312, we get 1 and a remainder of 171.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 312 from 483, we get 171.
Fetch the next digit (9) from the dividend, attach it to 171 and continue: 1719 / 312

Step 4:
312 can be fit into 1719 5 times, resulting in a remainder of 159.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
If we take 1560 away from 1719, we end up with 159.
Grab the next digit (6) from the dividend, add it to 159, then carry on: 1596 / 312

Moving on to step 5:
1596 divided by 312 is 5 with a remainder of 36.
Write down 5 as next digit of the result. 
Result so far: 155.0
Subtracting 1560 from 1596 leaves us with 36.
Fetch the next digit (5) from the dividend, attach it to 36 and continue: 365 / 312

Let's proceed to step 6:
365 divided by 312 is 1 with a remainder of 53.
The number 1 becomes the next digit in our result. 
Result so far: 1551.0
The remainder is 53 after subtracting 312 from 365.
Append the next digit (7) from the dividend to 53 and continue with: 537 / 312

Step 7:
When dividing 537 by 312, we get 1 with a remainder of 225.
Put 1 as the next digit of the answer. 
Result so far: 15511.0
If we subtract 312 from 537, we get 225.
Fetch the next digit (5) from the dividend, attach it to 225 and continue: 2255 / 312

Step 8:
When dividing 2255 by 312, we get 7 with a remainder of 71.
Use 7 as the next digit of our solution. 
Result so far: 155117.0
If we subtract 2184 from 2255, we get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Moving on to step 9:
710 divided by 312 is 2 with a remainder of 86.
The number 2 becomes the next digit in our result. 
Result so far: 155117.2
If we take 624 away from 710, we end up with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Moving on to step 10:
When dividing 860 by 312, we get 2 with a remainder of 236.
Put 2 as the next digit of the answer. 
Result so far: 155117.22
Deduct 624 from 860 and we're left with 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

The final outcome is 155117.22, with a leftover of 0.236.
