We divide 801969 by 3
The aim is to understand the frequency of 3 in 801969.

Moving on to step 1:
If we divide 8 by 3, we get 2 and a remainder of 2.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 6 from 8 leaves us with 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 3

Let's proceed to step 2:
20 divided by 3 is 6 with a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 26.0
Subtracting 18 from 20 leaves us with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 3

Step 3:
3 goes into 21 7 times with a remainder of 0.
The next digit of our result is 7. 
Result so far: 267.0
Deduct 21 from 21 and we're left with 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 3

Let's proceed to step 4:
3 can be fit into 9 3 times, resulting in a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 2673.0
If we take 9 away from 9, we end up with 0.
Fetch the next digit (6) from the dividend, attach it to 0 and continue: 6 / 3

Step 5:
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: 26732.0
If we subtract 6 from 6, we get 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 3

Advancing to step 6:
9 divided by 3 is 3 with a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 267323.0
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.

Advancing to step 7:
The number 3 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 267323.0
Subtract 0 from 0 to 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 8:
3 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 267323.0
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.

The quotient of the division is 267323.0, and the remainder is 0.0.
