We're dividing 306199 by 4 
The aim is to understand the frequency of 4 in 306199.

Advancing to step 1:
If we divide 3 by 4, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 4

On to step 2:
The number 4 fits into 30 7 times, leaving a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we take 28 away from 30, we end up with 2.
Take the next digit (6) from the dividend and append it to 2, then repeat: 26 / 4

On to step 3:
26 divided by 4 is 6 with a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 76.0
If we subtract 24 from 26, we get 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 4

Step 4:
If we divide 21 by 4, we get 5 and a remainder of 1.
The number 5 becomes the next digit in our result. 
Result so far: 765.0
Subtract 20 from 21 to get 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 4

Advancing to step 5:
19 divided by 4 is 4 with a remainder of 3.
Put 4 as the next digit of the answer. 
Result so far: 7654.0
The remainder is 3 after subtracting 16 from 19.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 4

Advancing to step 6:
When dividing 39 by 4, we get 9 with a remainder of 3.
The next digit of our result is 9. 
Result so far: 76549.0
If we subtract 36 from 39, we get 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:
If we divide 30 by 4, we get 7 and a remainder of 2.
The next digit of our result is 7. 
Result so far: 76549.7
Subtract 28 from 30 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 8:
4 goes into 20 5 times with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 76549.75
Subtract 20 from 20 to 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.

Step 9:
The number 4 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 76549.75
Deduct 0 from 0 and we're left 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 10:
4 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 76549.75
If we take 0 away from 0, we end up 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.

In conclusion, the division gives 76549.75 with a balance of 0.0.
