54771782 ÷ 3 
The aim is to understand the frequency of 3 in 54771782.

Step 1:
If we divide 5 by 3, we get 1 and a remainder of 2.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 3 from 5, we get 2.
Append the next digit (4) from the dividend to 2 and continue with: 24 / 3

Going ahead to step 2:
3 goes into 24 8 times with a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 18.0
Subtract 24 from 24 to get 0.
Take the next digit (7) from the dividend and append it to 0, then repeat: 7 / 3

Step 3:
3 goes into 7 2 times with a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 182.0
If we subtract 6 from 7, we get 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 3

Going ahead to step 4:
If we divide 17 by 3, we get 5 and a remainder of 2.
The number 5 becomes the next digit in our result. 
Result so far: 1825.0
Deduct 15 from 17 and we're left with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 3

Going ahead to step 5:
3 can be fit into 21 7 times, resulting in a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 18257.0
Subtract 21 from 21 to get 0.
Fetch the next digit (7) from the dividend, attach it to 0 and continue: 7 / 3

Going ahead to step 6:
3 can be fit into 7 2 times, resulting in a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 182572.0
If we take 6 away from 7, we end up with 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 3

Advancing to step 7:
When dividing 18 by 3, we get 6 with a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 1825726.0
The remainder is 0 after subtracting 18 from 18.
Fetch the next digit (2) from the dividend, attach it to 0 and continue: 2 / 3

Advancing to step 8:
3 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 18257260.0
Deduct 0 from 2 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.

Moving on to step 9:
When dividing 20 by 3, we get 6 with a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 18257260.6
Subtracting 18 from 20 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.

Going ahead to step 10:
When dividing 20 by 3, we get 6 with a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 18257260.66
Subtract 18 from 20 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.

The final result is 18257260.66 with a remainder of 0.002.
