Let's divide 12921406 by 500
We want to figure out the number of times 12921406 can be divided by 500.

Moving on to step 1:
When dividing 1 by 500, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 500

Advancing to step 2:
500 goes into 12 0 times with a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Take the next digit (9) from the dividend and append it to 12, then repeat: 129 / 500

Going ahead to step 3:
129 divided by 500 is 0 with a remainder of 129.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 129, we get 129.
Include the next digit (2) from the dividend after 129, then repeat: 1292 / 500

Advancing to step 4:
When dividing 1292 by 500, we get 2 with a remainder of 292.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 1000 from 1292 and we're left with 292.
Fetch the next digit (1) from the dividend, attach it to 292 and continue: 2921 / 500

Advancing to step 5:
500 goes into 2921 5 times with a remainder of 421.
Put 5 as the next digit of the answer. 
Result so far: 25.0
Subtract 2500 from 2921 to get 421.
Fetch the next digit (4) from the dividend, attach it to 421 and continue: 4214 / 500

Going ahead to step 6:
500 can be fit into 4214 8 times, resulting in a remainder of 214.
The number 8 becomes the next digit in our result. 
Result so far: 258.0
If we subtract 4000 from 4214, we get 214.
Grab the next digit (0) from the dividend, add it to 214, then carry on: 2140 / 500

On to step 7:
The number 500 fits into 2140 4 times, leaving a remainder of 140.
Use 4 as the next digit of our solution. 
Result so far: 2584.0
If we take 2000 away from 2140, we end up with 140.
Bring next digit (6) of the dividend behind the 140 and repeat the process: 1406 / 500

Advancing to step 8:
When dividing 1406 by 500, we get 2 with a remainder of 406.
The next digit of our result is 2. 
Result so far: 25842.0
Subtract 1000 from 1406 to get 406.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

On to step 9:
500 goes into 4060 8 times with a remainder of 60.
Record the quotient 8 as the next digit in the result. 
Result so far: 25842.8
If we subtract 4000 from 4060, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 10:
When dividing 600 by 500, we get 1 with a remainder of 100.
Put 1 as the next digit of the answer. 
Result so far: 25842.81
If we take 500 away from 600, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

On to step 11:
1000 divided by 500 is 2 with a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 25842.812
If we subtract 1000 from 1000, 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.

Let's proceed to step 12:
The number 500 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 25842.812
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.

Let's proceed to step 13:
The number 500 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 25842.812
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.

Our division results in 25842.812 with a remaining 0.0.
