We're dividing 471853 by 3 
The aim is to understand the frequency of 3 in 471853.

Moving on to step 1:
3 goes into 4 1 times with a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 3 from 4 leaves us with 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 3

Advancing to step 2:
When dividing 17 by 3, we get 5 with a remainder of 2.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
The remainder is 2 after subtracting 15 from 17.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 3

Going ahead to step 3:
21 divided by 3 is 7 with a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 157.0
Deduct 21 from 21 and we're left with 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 3

Step 4:
The number 3 fits into 8 2 times, leaving a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 1572.0
Subtract 6 from 8 to get 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 3

On to step 5:
3 goes into 25 8 times with a remainder of 1.
Write down 8 as next digit of the result. 
Result so far: 15728.0
Subtracting 24 from 25 leaves us with 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 3

Advancing to step 6:
If we divide 13 by 3, we get 4 and a remainder of 1.
The number 4 becomes the next digit in our result. 
Result so far: 157284.0
Deduct 12 from 13 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.

Going ahead to step 7:
If we divide 10 by 3, we get 3 and a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 157284.3
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: 157284.33
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.

Our division results in 157284.33 with a remaining 0.001.
