We look at the division of 777630 by 4 
The aim is to understand the frequency of 4 in 777630.

Let's proceed to step 1:
When dividing 7 by 4, we get 1 with a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 4 from 7 and we're left with 3.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 4

Step 2:
37 divided by 4 is 9 with a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 19.0
Subtracting 36 from 37 leaves us with 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 4

Going ahead to step 3:
The number 4 fits into 17 4 times, leaving a remainder of 1.
The number 4 becomes the next digit in our result. 
Result so far: 194.0
If we take 16 away from 17, we end up with 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 4

Going ahead to step 4:
4 goes into 16 4 times with a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 1944.0
Deduct 16 from 16 and we're left with 0.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 4

Step 5:
When dividing 3 by 4, we get 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 19440.0
Subtract 0 from 3 to get 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 4

Going ahead to step 6:
4 goes into 30 7 times with a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 194407.0
The remainder is 2 after subtracting 28 from 30.
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 7:
4 can be fit into 20 5 times, resulting in a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 194407.5
If we subtract 20 from 20, we 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.

Advancing to step 8:
0 divided by 4 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 194407.5
Subtract 0 from 0 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.

Going ahead to step 9:
4 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 194407.5
Subtracting 0 from 0 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.

The quotient of the division is 194407.5, and the remainder is 0.0.
