We divide 721036 by 10
The aim is to understand the frequency of 10 in 721036.

Going ahead to step 1:
10 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 10

Step 2:
The number 10 fits into 72 7 times, leaving a remainder of 2.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtract 70 from 72 to get 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 10

Going ahead to step 3:
10 goes into 21 2 times with a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 72.0
Subtracting 20 from 21 leaves us with 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 10

Going ahead to step 4:
10 divided by 10 is 1 with a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 721.0
If we subtract 10 from 10, we get 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 10

Moving on to step 5:
When dividing 3 by 10, we get 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 7210.0
If we subtract 0 from 3, we get 3.
Grab the next digit (6) from the dividend, add it to 3, then carry on: 36 / 10

Step 6:
36 divided by 10 is 3 with a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 72103.0
Deduct 30 from 36 and we're left 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.

Advancing to step 7:
The number 10 fits into 60 6 times, leaving a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 72103.6
Subtract 60 from 60 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.

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: 72103.6
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:
10 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 72103.6
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 final result is 72103.6 with a remainder of 0.0.
