780783 ÷ 4 
The aim is to understand the frequency of 4 in 780783.

Moving on to step 1:
If we divide 7 by 4, we get 1 and a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 4 from 7 to get 3.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 4

Moving on to step 2:
If we divide 38 by 4, we get 9 and a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
Subtracting 36 from 38 leaves us with 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 4

Moving on to step 3:
If we divide 20 by 4, we get 5 and a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 195.0
Subtract 20 from 20 to get 0.
Take the next digit (7) from the dividend and append it to 0, then repeat: 7 / 4

On to step 4:
4 can be fit into 7 1 times, resulting in a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 1951.0
Subtracting 4 from 7 leaves us with 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 4

Moving on to step 5:
The number 4 fits into 38 9 times, leaving a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 19519.0
If we subtract 36 from 38, we get 2.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 4

Let's proceed to step 6:
When dividing 23 by 4, we get 5 with a remainder of 3.
Record the quotient 5 as the next digit in the result. 
Result so far: 195195.0
Subtracting 20 from 23 leaves us 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.

On 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: 195195.7
Subtracting 28 from 30 leaves us 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.

Moving on to step 8:
4 goes into 20 5 times with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 195195.75
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:
4 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 195195.75
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.

Moving on to step 10:
When dividing 0 by 4, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 195195.75
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.

After the division, we end up with 195195.75 and a remainder of 0.0.
