Let's divide 661947 by 5
The aim is to understand the frequency of 5 in 661947.

On to step 1:
When dividing 6 by 5, we get 1 with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 5 from 6 leaves us with 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 5

On to step 2:
5 goes into 16 3 times with a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 13.0
If we subtract 15 from 16, we get 1.
Append the next digit (1) from the dividend to 1 and continue with: 11 / 5

Step 3:
11 divided by 5 is 2 with a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 132.0
If we subtract 10 from 11, we get 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 5

Advancing to step 4:
When dividing 19 by 5, we get 3 with a remainder of 4.
The next digit of our result is 3. 
Result so far: 1323.0
If we take 15 away from 19, we end up with 4.
Take the next digit (4) from the dividend and append it to 4, then repeat: 44 / 5

Advancing to step 5:
5 goes into 44 8 times with a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 13238.0
Subtracting 40 from 44 leaves us with 4.
Append the next digit (7) from the dividend to 4 and continue with: 47 / 5

On to step 6:
5 can be fit into 47 9 times, resulting in a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 132389.0
Subtracting 45 from 47 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 7:
5 goes into 20 4 times with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 132389.4
Deduct 20 from 20 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.

Going ahead to step 8:
5 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 132389.4
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 9:
5 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 132389.4
The remainder is 0 after subtracting 0 from 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 132389.4 and a remainder of 0.0.
