We divide 600037 by 3
The aim is to understand the frequency of 3 in 600037.

Let's proceed to step 1:
The number 3 fits into 6 2 times, leaving a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 0 after subtracting 6 from 6.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 3

Moving on to step 2:
0 divided by 3 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 20.0
Deduct 0 from 0 and we're left with 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 3

Let's proceed to step 3:
3 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 200.0
If we take 0 away from 0, we end up with 0.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 3

Advancing to step 4:
0 divided by 3 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 2000.0
If we take 0 away from 0, we end up with 0.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 3

Step 5:
3 goes into 3 1 times with a remainder of 0.
The next digit of our result is 1. 
Result so far: 20001.0
Subtract 3 from 3 to get 0.
Include the next digit (7) from the dividend after 0, then repeat: 7 / 3

Step 6:
If we divide 7 by 3, we get 2 and a remainder of 1.
The next digit of our result is 2. 
Result so far: 200012.0
Subtract 6 from 7 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.

Moving on to step 7:
The number 3 fits into 10 3 times, leaving a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 200012.3
If we subtract 9 from 10, we 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.

Going ahead to step 8:
3 can be fit into 10 3 times, resulting in a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 200012.33
If we subtract 9 from 10, we 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.

The final result is 200012.33 with a remainder of 0.001.
