We're dividing 206819 by 4 
The aim is to understand the frequency of 4 in 206819.

Going ahead to step 1:
If we divide 2 by 4, we get 0 and a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 4

Advancing to step 2:
If we divide 20 by 4, we get 5 and a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtract 20 from 20 to get 0.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 4

Moving on to step 3:
The number 4 fits into 6 1 times, leaving a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 51.0
Subtract 4 from 6 to get 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 4

Advancing to step 4:
If we divide 28 by 4, we get 7 and a remainder of 0.
The next digit of our result is 7. 
Result so far: 517.0
If we subtract 28 from 28, we get 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 4

On to step 5:
The number 4 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 5170.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 4

Advancing to step 6:
The number 4 fits into 19 4 times, leaving a remainder of 3.
Write down 4 as next digit of the result. 
Result so far: 51704.0
Subtract 16 from 19 to 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.

Going ahead to step 7:
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: 51704.7
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.

On to step 8:
When dividing 20 by 4, we get 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 51704.75
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.

Moving on to step 9:
When dividing 0 by 4, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 51704.75
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.

Moving on to step 10:
When dividing 0 by 4, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 51704.75
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.

In conclusion, the division gives 51704.75 with a balance of 0.0.
