We're dividing 483921 by 10 
The aim is to understand the frequency of 10 in 483921.

Advancing to step 1:
4 divided by 10 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Include the next digit (8) from the dividend after 4, then repeat: 48 / 10

On to step 2:
10 goes into 48 4 times with a remainder of 8.
The next digit of our result is 4. 
Result so far: 4.0
Subtracting 40 from 48 leaves us with 8.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 10

Let's proceed to step 3:
10 goes into 83 8 times with a remainder of 3.
Put 8 as the next digit of the answer. 
Result so far: 48.0
Subtracting 80 from 83 leaves us with 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 10

Let's proceed to step 4:
The number 10 fits into 39 3 times, leaving a remainder of 9.
Put 3 as the next digit of the answer. 
Result so far: 483.0
The remainder is 9 after subtracting 30 from 39.
Grab the next digit (2) from the dividend, add it to 9, then carry on: 92 / 10

Let's proceed to step 5:
If we divide 92 by 10, we get 9 and a remainder of 2.
Put 9 as the next digit of the answer. 
Result so far: 4839.0
The remainder is 2 after subtracting 90 from 92.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 10

Moving on to step 6:
10 goes into 21 2 times with a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 48392.0
Subtract 20 from 21 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 7:
The number 10 fits into 10 1 times, leaving a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 48392.1
Subtracting 10 from 10 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.

On to step 8:
If we divide 0 by 10, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 48392.1
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.

Advancing to step 9:
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: 48392.1
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.

The final outcome is 48392.1, with a leftover of 0.0.
