We divide 974190 by 3
The aim is to understand the frequency of 3 in 974190.

Let's proceed to step 1:
9 divided by 3 is 3 with a remainder of 0.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 9 from 9 and we're left with 0.
Grab the next digit (7) from the dividend, add it to 0, then carry on: 7 / 3

Advancing to step 2:
The number 3 fits into 7 2 times, leaving a remainder of 1.
The next digit of our result is 2. 
Result so far: 32.0
Subtracting 6 from 7 leaves us with 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 3

Let's proceed to step 3:
3 goes into 14 4 times with a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 324.0
If we take 12 away from 14, we end up with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 3

Step 4:
When dividing 21 by 3, we get 7 with a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 3247.0
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

Going ahead to step 5:
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: 32473.0
If we subtract 9 from 9, we get 0.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 3

Going ahead to step 6:
The number 3 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 324730.0
Subtracting 0 from 0 leaves us 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.

Going ahead to step 7:
3 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 324730.0
If we subtract 0 from 0, 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 8:
The number 3 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 324730.0
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 324730.0 and a remainder of 0.0.
