657874 divided by 3 
The aim is to understand the frequency of 3 in 657874.

Moving on to step 1:
If we divide 6 by 3, we get 2 and a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 6 from 6 to get 0.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 3

Step 2:
3 goes into 5 1 times with a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 21.0
If we take 3 away from 5, we end up with 2.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 3

Advancing to step 3:
3 can be fit into 27 9 times, resulting in a remainder of 0.
The next digit of our result is 9. 
Result so far: 219.0
If we subtract 27 from 27, we get 0.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 3

Advancing to step 4:
3 goes into 8 2 times with a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 2192.0
Deduct 6 from 8 and we're left with 2.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 3

Step 5:
When dividing 27 by 3, we get 9 with a remainder of 0.
The next digit of our result is 9. 
Result so far: 21929.0
Subtract 27 from 27 to get 0.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 3

Moving on to step 6:
3 goes into 4 1 times with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 219291.0
Subtract 3 from 4 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 7:
The number 3 fits into 10 3 times, leaving a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 219291.3
If we take 9 away from 10, we end up 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.

Step 8:
10 divided by 3 is 3 with a remainder of 1.
The next digit of our result is 3. 
Result so far: 219291.33
Subtracting 9 from 10 leaves us 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.

The quotient of the division is 219291.33, and the remainder is 0.001.
