548526 divided by 3 
The aim is to understand the frequency of 3 in 548526.

Advancing to step 1:
When dividing 5 by 3, we get 1 with a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 3 from 5 to get 2.
Fetch the next digit (4) from the dividend, attach it to 2 and continue: 24 / 3

Let's proceed to step 2:
3 can be fit into 24 8 times, resulting in a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 18.0
If we take 24 away from 24, we end up with 0.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 3

Moving on to step 3:
When dividing 8 by 3, we get 2 with a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 182.0
Subtract 6 from 8 to get 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 3

On to step 4:
If we divide 25 by 3, we get 8 and a remainder of 1.
Put 8 as the next digit of the answer. 
Result so far: 1828.0
If we take 24 away from 25, we end up with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 3

Going ahead to step 5:
12 divided by 3 is 4 with a remainder of 0.
The next digit of our result is 4. 
Result so far: 18284.0
If we take 12 away from 12, we end up with 0.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 3

On to step 6:
3 goes into 6 2 times with a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 182842.0
Subtract 6 from 6 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.

On to step 7:
0 divided by 3 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 182842.0
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.

Step 8:
3 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 182842.0
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 182842.0 with a remainder of 0.0.
