We divide 25440023 by 800
Let's see how many times 800 fits into 25440023.

Moving on to step 1:
2 divided by 800 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 800

Moving on to step 2:
The number 800 fits into 25 0 times, leaving a remainder of 25.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 25, we end up with 25.
Append the next digit (4) from the dividend to 25 and continue with: 254 / 800

On to step 3:
800 goes into 254 0 times with a remainder of 254.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 254, we end up with 254.
Bring next digit (4) of the dividend behind the 254 and repeat the process: 2544 / 800

Advancing to step 4:
800 can be fit into 2544 3 times, resulting in a remainder of 144.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Deduct 2400 from 2544 and we're left with 144.
Fetch the next digit (0) from the dividend, attach it to 144 and continue: 1440 / 800

Moving on to step 5:
800 can be fit into 1440 1 times, resulting in a remainder of 640.
Use 1 as the next digit of our solution. 
Result so far: 31.0
If we take 800 away from 1440, we end up with 640.
Append the next digit (0) from the dividend to 640 and continue with: 6400 / 800

On to step 6:
800 goes into 6400 8 times with a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 318.0
If we subtract 6400 from 6400, we get 0.
Take the next digit (2) from the dividend and append it to 0, then repeat: 2 / 800

Going ahead to step 7:
If we divide 2 by 800, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 3180.0
If we subtract 0 from 2, we get 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 800

Advancing to step 8:
800 can be fit into 23 0 times, resulting in a remainder of 23.
The next digit of our result is 0. 
Result so far: 31800.0
If we take 0 away from 23, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 9:
800 can be fit into 230 0 times, resulting in a remainder of 230.
Use 0 as the next digit of our solution. 
Result so far: 31800.0
If we take 0 away from 230, we end up with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

On to step 10:
800 can be fit into 2300 2 times, resulting in a remainder of 700.
Use 2 as the next digit of our solution. 
Result so far: 31800.02
Deduct 1600 from 2300 and we're left with 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Going ahead to step 11:
7000 divided by 800 is 8 with a remainder of 600.
Put 8 as the next digit of the answer. 
Result so far: 31800.028
The remainder is 600 after subtracting 6400 from 7000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Moving on to step 12:
If we divide 6000 by 800, we get 7 and a remainder of 400.
Use 7 as the next digit of our solution. 
Result so far: 31800.0287
Subtract 5600 from 6000 to get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Advancing to step 13:
800 goes into 4000 5 times with a remainder of 0.
The next digit of our result is 5. 
Result so far: 31800.02875
Subtracting 4000 from 4000 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.

Going ahead to step 14:
When dividing 0 by 800, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 31800.02875
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.

Going ahead to step 15:
800 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 31800.02875
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.

Our division results in 31800.02875 with a remaining 0.0.
