We divide 652138 by 3
The aim is to understand the frequency of 3 in 652138.

Going ahead to step 1:
If we divide 6 by 3, we get 2 and a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 6 from 6, we get 0.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 3

Going ahead to step 2:
3 goes into 5 1 times with a remainder of 2.
The next digit of our result is 1. 
Result so far: 21.0
If we take 3 away from 5, we end up with 2.
Grab the next digit (2) from the dividend, add it to 2, then carry on: 22 / 3

On to step 3:
If we divide 22 by 3, we get 7 and a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 217.0
Subtract 21 from 22 to get 1.
Grab the next digit (1) from the dividend, add it to 1, then carry on: 11 / 3

Advancing to step 4:
When dividing 11 by 3, we get 3 with a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 2173.0
Subtracting 9 from 11 leaves us with 2.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 3

On to step 5:
23 divided by 3 is 7 with a remainder of 2.
Write down 7 as next digit of the result. 
Result so far: 21737.0
Subtract 21 from 23 to get 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 3

Moving on to step 6:
3 can be fit into 28 9 times, resulting in a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 217379.0
The remainder is 1 after subtracting 27 from 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

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: 217379.3
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.

On to step 8:
3 can be fit into 10 3 times, resulting in a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 217379.33
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.

The final outcome is 217379.33, with a leftover of 0.001.
