199534 divided by 3 
The aim is to understand the frequency of 3 in 199534.

Going ahead to step 1:
3 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 3

Step 2:
19 divided by 3 is 6 with a remainder of 1.
The next digit of our result is 6. 
Result so far: 6.0
The remainder is 1 after subtracting 18 from 19.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 3

Step 3:
3 can be fit into 19 6 times, resulting in a remainder of 1.
The next digit of our result is 6. 
Result so far: 66.0
If we subtract 18 from 19, we get 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 3

Step 4:
3 goes into 15 5 times with a remainder of 0.
The next digit of our result is 5. 
Result so far: 665.0
Subtract 15 from 15 to get 0.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 3

On to step 5:
3 can be fit into 3 1 times, resulting in a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 6651.0
Deduct 3 from 3 and we're left with 0.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 3

Moving on to step 6:
4 divided by 3 is 1 with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 66511.0
Deduct 3 from 4 and we're left 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.

Step 7:
3 goes into 10 3 times with a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 66511.3
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.

Advancing to step 8:
3 goes into 10 3 times with a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 66511.33
Subtracting 9 from 10 leaves us 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 result is 66511.33 with a remainder of 0.001.
