661472 ÷ 10 
The aim is to understand the frequency of 10 in 661472.

Let's proceed to step 1:
The number 10 fits into 6 0 times, leaving a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 10

Step 2:
When dividing 66 by 10, we get 6 with a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Deduct 60 from 66 and we're left with 6.
Bring next digit (1) of the dividend behind the 6 and repeat the process: 61 / 10

Let's proceed to step 3:
The number 10 fits into 61 6 times, leaving a remainder of 1.
Write down 6 as next digit of the result. 
Result so far: 66.0
If we take 60 away from 61, we end up with 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 10

Advancing to step 4:
10 goes into 14 1 times with a remainder of 4.
The next digit of our result is 1. 
Result so far: 661.0
Subtracting 10 from 14 leaves us with 4.
Include the next digit (7) from the dividend after 4, then repeat: 47 / 10

Advancing to step 5:
The number 10 fits into 47 4 times, leaving a remainder of 7.
The next digit of our result is 4. 
Result so far: 6614.0
Deduct 40 from 47 and we're left with 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 10

Step 6:
10 can be fit into 72 7 times, resulting in a remainder of 2.
Record the quotient 7 as the next digit in the result. 
Result so far: 66147.0
If we take 70 away from 72, we end up 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.

Moving on to step 7:
If we divide 20 by 10, we get 2 and a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 66147.2
Subtracting 20 from 20 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.

Step 8:
The number 10 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 66147.2
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.

Going ahead to step 9:
If we divide 0 by 10, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 66147.2
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.

After the division, we end up with 66147.2 and a remainder of 0.0.
