We look at the division of 630858 by 10 
The aim is to understand the frequency of 10 in 630858.

Going ahead to step 1:
When dividing 6 by 10, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 10

Going ahead to step 2:
10 can be fit into 63 6 times, resulting in a remainder of 3.
Put 6 as the next digit of the answer. 
Result so far: 6.0
If we take 60 away from 63, we end up with 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 10

Let's proceed to step 3:
The number 10 fits into 30 3 times, leaving a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 63.0
Subtract 30 from 30 to get 0.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 10

Step 4:
10 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 630.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 10

Going ahead to step 5:
The number 10 fits into 85 8 times, leaving a remainder of 5.
Use 8 as the next digit of our solution. 
Result so far: 6308.0
If we take 80 away from 85, we end up with 5.
Grab the next digit (8) from the dividend, add it to 5, then carry on: 58 / 10

Moving on to step 6:
58 divided by 10 is 5 with a remainder of 8.
The next digit of our result is 5. 
Result so far: 63085.0
If we subtract 50 from 58, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 7:
10 goes into 80 8 times with a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 63085.8
If we subtract 80 from 80, 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.

Going ahead to step 8:
The number 10 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 63085.8
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.

Going ahead to step 9:
The number 10 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 63085.8
If we subtract 0 from 0, 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.

The final result is 63085.8 with a remainder of 0.0.
