601836 ÷ 3 
The aim is to understand the frequency of 3 in 601836.

Step 1:
The number 3 fits into 6 2 times, leaving a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 6 from 6, we get 0.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 3

Moving on to step 2:
If we divide 0 by 3, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
If we subtract 0 from 0, we get 0.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 3

Let's proceed to step 3:
The number 3 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 200.0
If we take 0 away from 1, we end up with 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 3

Step 4:
The number 3 fits into 18 6 times, leaving a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 2006.0
The remainder is 0 after subtracting 18 from 18.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 3

Step 5:
The number 3 fits into 3 1 times, leaving a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 20061.0
If we subtract 3 from 3, we get 0.
Fetch the next digit (6) from the dividend, attach it to 0 and continue: 6 / 3

On to step 6:
The number 3 fits into 6 2 times, leaving a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 200612.0
Deduct 6 from 6 and we're left 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 7:
When dividing 0 by 3, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 200612.0
If we subtract 0 from 0, 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.

Let's proceed to step 8:
When dividing 0 by 3, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 200612.0
If we subtract 0 from 0, 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.

The final outcome is 200612.0, with a leftover of 0.0.
