We're dividing 403216 by 10 
The aim is to understand the frequency of 10 in 403216.

Going ahead to step 1:
When dividing 4 by 10, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 10

Advancing to step 2:
40 divided by 10 is 4 with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Deduct 40 from 40 and we're left with 0.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 10

Let's proceed to step 3:
The number 10 fits into 3 0 times, leaving a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 40.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (2) from the dividend, attach it to 3 and continue: 32 / 10

Going ahead to step 4:
10 can be fit into 32 3 times, resulting in a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 403.0
Subtract 30 from 32 to get 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 10

Let's proceed to step 5:
When dividing 21 by 10, we get 2 with a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 4032.0
The remainder is 1 after subtracting 20 from 21.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 10

Step 6:
The number 10 fits into 16 1 times, leaving a remainder of 6.
The number 1 becomes the next digit in our result. 
Result so far: 40321.0
Subtracting 10 from 16 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 7:
When dividing 60 by 10, we get 6 with a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 40321.6
If we subtract 60 from 60, 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.

Advancing to step 8:
10 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 40321.6
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.

Step 9:
The number 10 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 40321.6
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.

The final outcome is 40321.6, with a leftover of 0.0.
