21456596 divided by 10 
We want to figure out the number of times 21456596 can be divided by 10.

Let's proceed to step 1:
When dividing 2 by 10, we get 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 10

Moving on to step 2:
When dividing 21 by 10, we get 2 with a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 20 from 21 to get 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 10

Step 3:
When dividing 14 by 10, we get 1 with a remainder of 4.
Write down 1 as next digit of the result. 
Result so far: 21.0
Deduct 10 from 14 and we're left with 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 10

On to step 4:
The number 10 fits into 45 4 times, leaving a remainder of 5.
Use 4 as the next digit of our solution. 
Result so far: 214.0
Subtracting 40 from 45 leaves us with 5.
Grab the next digit (6) from the dividend, add it to 5, then carry on: 56 / 10

Going ahead to step 5:
10 can be fit into 56 5 times, resulting in a remainder of 6.
The number 5 becomes the next digit in our result. 
Result so far: 2145.0
Deduct 50 from 56 and we're left with 6.
Append the next digit (5) from the dividend to 6 and continue with: 65 / 10

Moving on to step 6:
65 divided by 10 is 6 with a remainder of 5.
Write down 6 as next digit of the result. 
Result so far: 21456.0
The remainder is 5 after subtracting 60 from 65.
Fetch the next digit (9) from the dividend, attach it to 5 and continue: 59 / 10

Advancing to step 7:
59 divided by 10 is 5 with a remainder of 9.
Put 5 as the next digit of the answer. 
Result so far: 214565.0
The remainder is 9 after subtracting 50 from 59.
Take the next digit (6) from the dividend and append it to 9, then repeat: 96 / 10

Going ahead to step 8:
96 divided by 10 is 9 with a remainder of 6.
Write down 9 as next digit of the result. 
Result so far: 2145659.0
Subtracting 90 from 96 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 9:
10 goes into 60 6 times with a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 2145659.6
Deduct 60 from 60 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 10:
The number 10 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 2145659.6
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.

Step 11:
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: 2145659.6
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 2145659.6 with a remainder of 0.0.
