893520 ÷ 3 
The aim is to understand the frequency of 3 in 893520.

On to step 1:
The number 3 fits into 8 2 times, leaving a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 2 after subtracting 6 from 8.
Bring next digit (9) of the dividend behind the 2 and repeat the process: 29 / 3

Advancing to step 2:
29 divided by 3 is 9 with a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 29.0
If we subtract 27 from 29, we get 2.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 3

Advancing to step 3:
23 divided by 3 is 7 with a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 297.0
The remainder is 2 after subtracting 21 from 23.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 3

Advancing to step 4:
When dividing 25 by 3, we get 8 with a remainder of 1.
Record the quotient 8 as the next digit in the result. 
Result so far: 2978.0
Subtracting 24 from 25 leaves us with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 3

Moving on to step 5:
3 goes into 12 4 times with a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 29784.0
The remainder is 0 after subtracting 12 from 12.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 3

Let's proceed to step 6:
When dividing 0 by 3, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 297840.0
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.

On to step 7:
If we divide 0 by 3, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 297840.0
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.

Moving on to step 8:
3 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 297840.0
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.

Our division results in 297840.0 with a remaining 0.0.
