386026 ÷ 3 
The aim is to understand the frequency of 3 in 386026.

On to step 1:
If we divide 3 by 3, we get 1 and a remainder of 0.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 0 after subtracting 3 from 3.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 3

Step 2:
If we divide 8 by 3, we get 2 and a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Subtract 6 from 8 to get 2.
Grab the next digit (6) from the dividend, add it to 2, then carry on: 26 / 3

Step 3:
When dividing 26 by 3, we get 8 with a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 128.0
If we take 24 away from 26, we end up with 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 3

Step 4:
The number 3 fits into 20 6 times, leaving a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 1286.0
The remainder is 2 after subtracting 18 from 20.
Append the next digit (2) from the dividend to 2 and continue with: 22 / 3

Let's proceed to step 5:
When dividing 22 by 3, we get 7 with a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 12867.0
Subtract 21 from 22 to get 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 3

Step 6:
The number 3 fits into 16 5 times, leaving a remainder of 1.
Put 5 as the next digit of the answer. 
Result so far: 128675.0
Subtract 15 from 16 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 7:
10 divided by 3 is 3 with a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 128675.3
If we take 9 away from 10, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 8:
3 can be fit into 10 3 times, resulting in a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 128675.33
Subtract 9 from 10 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

After the division, we end up with 128675.33 and a remainder of 0.001.
