We divide 947289 by 3
The aim is to understand the frequency of 3 in 947289.

Moving on to step 1:
The number 3 fits into 9 3 times, leaving a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
The remainder is 0 after subtracting 9 from 9.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 3

Advancing to step 2:
4 divided by 3 is 1 with a remainder of 1.
The next digit of our result is 1. 
Result so far: 31.0
Subtract 3 from 4 to get 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 3

Moving on to step 3:
When dividing 17 by 3, we get 5 with a remainder of 2.
Put 5 as the next digit of the answer. 
Result so far: 315.0
If we subtract 15 from 17, we get 2.
Bring next digit (2) of the dividend behind the 2 and repeat the process: 22 / 3

Step 4:
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: 3157.0
Subtract 21 from 22 to get 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 3

Let's proceed to step 5:
3 goes into 18 6 times with a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 31576.0
If we subtract 18 from 18, we get 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 3

Going ahead to step 6:
The number 3 fits into 9 3 times, leaving a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 315763.0
If we subtract 9 from 9, 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.

On to step 7:
3 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 315763.0
Deduct 0 from 0 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.

Advancing to step 8:
If we divide 0 by 3, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 315763.0
If we take 0 away from 0, we end up 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.

After the division, we end up with 315763.0 and a remainder of 0.0.
