312195 divided by 4 
The aim is to understand the frequency of 4 in 312195.

On to step 1:
4 can be fit into 3 0 times, resulting in a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 4

Moving on to step 2:
4 can be fit into 31 7 times, resulting in a remainder of 3.
The next digit of our result is 7. 
Result so far: 7.0
The remainder is 3 after subtracting 28 from 31.
Append the next digit (2) from the dividend to 3 and continue with: 32 / 4

Let's proceed to step 3:
If we divide 32 by 4, we get 8 and a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 78.0
If we take 32 away from 32, we end up with 0.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 4

Let's proceed to step 4:
The number 4 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 780.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 4

Let's proceed to step 5:
4 goes into 19 4 times with a remainder of 3.
Record the quotient 4 as the next digit in the result. 
Result so far: 7804.0
The remainder is 3 after subtracting 16 from 19.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 4

Going ahead to step 6:
When dividing 35 by 4, we get 8 with a remainder of 3.
The number 8 becomes the next digit in our result. 
Result so far: 78048.0
If we take 32 away from 35, 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.

Advancing to step 7:
4 can be fit into 30 7 times, resulting in a remainder of 2.
Write down 7 as next digit of the result. 
Result so far: 78048.7
Deduct 28 from 30 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 8:
20 divided by 4 is 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 78048.75
Subtracting 20 from 20 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.

Going ahead to step 9:
0 divided by 4 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 78048.75
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 10:
0 divided by 4 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 78048.75
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.

In conclusion, the division gives 78048.75 with a balance of 0.0.
