20007493 ÷ 800 
We want to divide 20007493 by 800.

Let's proceed to step 1:
The number 800 fits into 2 0 times, leaving a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 800

Moving on to step 2:
If we divide 20 by 800, we get 0 and a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 20, we end up with 20.
Bring next digit (0) of the dividend behind the 20 and repeat the process: 200 / 800

Going ahead to step 3:
When dividing 200 by 800, we get 0 with a remainder of 200.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 200, we end up with 200.
Include the next digit (0) from the dividend after 200, then repeat: 2000 / 800

On to step 4:
If we divide 2000 by 800, we get 2 and a remainder of 400.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 1600 from 2000 to get 400.
Take the next digit (7) from the dividend and append it to 400, then repeat: 4007 / 800

Advancing to step 5:
The number 800 fits into 4007 5 times, leaving a remainder of 7.
The next digit of our result is 5. 
Result so far: 25.0
Subtract 4000 from 4007 to get 7.
Take the next digit (4) from the dividend and append it to 7, then repeat: 74 / 800

On to step 6:
When dividing 74 by 800, we get 0 with a remainder of 74.
Put 0 as the next digit of the answer. 
Result so far: 250.0
If we subtract 0 from 74, we get 74.
Include the next digit (9) from the dividend after 74, then repeat: 749 / 800

Moving on to step 7:
749 divided by 800 is 0 with a remainder of 749.
Use 0 as the next digit of our solution. 
Result so far: 2500.0
If we take 0 away from 749, we end up with 749.
Take the next digit (3) from the dividend and append it to 749, then repeat: 7493 / 800

Advancing to step 8:
When dividing 7493 by 800, we get 9 with a remainder of 293.
Put 9 as the next digit of the answer. 
Result so far: 25009.0
Deduct 7200 from 7493 and we're left with 293.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2930, and continue the process.

Going ahead to step 9:
The number 800 fits into 2930 3 times, leaving a remainder of 530.
The number 3 becomes the next digit in our result. 
Result so far: 25009.3
Subtracting 2400 from 2930 leaves us with 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

Step 10:
800 can be fit into 5300 6 times, resulting in a remainder of 500.
Use 6 as the next digit of our solution. 
Result so far: 25009.36
Subtracting 4800 from 5300 leaves us with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Step 11:
If we divide 5000 by 800, we get 6 and a remainder of 200.
Write down 6 as next digit of the result. 
Result so far: 25009.366
If we subtract 4800 from 5000, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

After the division, we end up with 25009.366 and a remainder of 0.02.
