Let's divide 990985 by 10
The aim is to understand the frequency of 10 in 990985.

Step 1:
When dividing 9 by 10, we get 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 10

Step 2:
If we divide 99 by 10, we get 9 and a remainder of 9.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Deduct 90 from 99 and we're left with 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 10

Going ahead to step 3:
90 divided by 10 is 9 with a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 99.0
Subtracting 90 from 90 leaves us with 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 10

Going ahead to step 4:
If we divide 9 by 10, we get 0 and a remainder of 9.
The next digit of our result is 0. 
Result so far: 990.0
Subtracting 0 from 9 leaves us with 9.
Grab the next digit (8) from the dividend, add it to 9, then carry on: 98 / 10

Step 5:
10 can be fit into 98 9 times, resulting in a remainder of 8.
Record the quotient 9 as the next digit in the result. 
Result so far: 9909.0
Subtract 90 from 98 to get 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 10

Let's proceed to step 6:
The number 10 fits into 85 8 times, leaving a remainder of 5.
Record the quotient 8 as the next digit in the result. 
Result so far: 99098.0
If we subtract 80 from 85, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 7:
10 can be fit into 50 5 times, resulting in a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 99098.5
If we subtract 50 from 50, 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.

Let's proceed to step 8:
When dividing 0 by 10, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 99098.5
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.

Let's proceed to step 9:
When dividing 0 by 10, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 99098.5
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.

The final result is 99098.5 with a remainder of 0.0.
