Let's divide 687009 by 10
The aim is to understand the frequency of 10 in 687009.

Step 1:
When dividing 6 by 10, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 10

Advancing to step 2:
If we divide 68 by 10, we get 6 and a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Subtracting 60 from 68 leaves us with 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 10

Let's proceed to step 3:
10 goes into 87 8 times with a remainder of 7.
Write down 8 as next digit of the result. 
Result so far: 68.0
If we take 80 away from 87, we end up with 7.
Bring next digit (0) of the dividend behind the 7 and repeat the process: 70 / 10

Moving on to step 4:
The number 10 fits into 70 7 times, leaving a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 687.0
The remainder is 0 after subtracting 70 from 70.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 10

Step 5:
10 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 6870.0
Deduct 0 from 0 and we're left with 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 10

Step 6:
The number 10 fits into 9 0 times, leaving a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 68700.0
If we take 0 away from 9, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 7:
90 divided by 10 is 9 with a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 68700.9
The remainder is 0 after subtracting 90 from 90.
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:
10 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 68700.9
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 9:
The number 10 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 68700.9
Subtract 0 from 0 to 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.

The quotient of the division is 68700.9, and the remainder is 0.0.
