Let's divide 770448 by 3
The aim is to understand the frequency of 3 in 770448.

Advancing to step 1:
If we divide 7 by 3, we get 2 and a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 6 away from 7, we end up with 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 3

Going ahead to step 2:
17 divided by 3 is 5 with a remainder of 2.
Use 5 as the next digit of our solution. 
Result so far: 25.0
If we subtract 15 from 17, we get 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 3

Step 3:
If we divide 20 by 3, we get 6 and a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 256.0
Subtracting 18 from 20 leaves us with 2.
Take the next digit (4) from the dividend and append it to 2, then repeat: 24 / 3

Step 4:
3 goes into 24 8 times with a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 2568.0
Subtracting 24 from 24 leaves us with 0.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 3

Let's proceed to step 5:
If we divide 4 by 3, we get 1 and a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 25681.0
Deduct 3 from 4 and we're left with 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 3

Going ahead to step 6:
If we divide 18 by 3, we get 6 and a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 256816.0
If we subtract 18 from 18, 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.

On to step 7:
The number 3 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 256816.0
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.

Advancing to step 8:
If we divide 0 by 3, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 256816.0
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 final result is 256816.0 with a remainder of 0.0.
