We're dividing 25156013 by 800 
We're looking to find how many times 800 goes into 25156013.

Let's proceed to step 1:
800 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 800

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.
Include the next digit (1) from the dividend after 25, then repeat: 251 / 800

Going ahead to step 3:
The number 800 fits into 251 0 times, leaving a remainder of 251.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 251 to get 251.
Include the next digit (5) from the dividend after 251, then repeat: 2515 / 800

Step 4:
800 goes into 2515 3 times with a remainder of 115.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 2400 from 2515 leaves us with 115.
Take the next digit (6) from the dividend and append it to 115, then repeat: 1156 / 800

On to step 5:
800 can be fit into 1156 1 times, resulting in a remainder of 356.
Put 1 as the next digit of the answer. 
Result so far: 31.0
Deduct 800 from 1156 and we're left with 356.
Take the next digit (0) from the dividend and append it to 356, then repeat: 3560 / 800

Moving on to step 6:
The number 800 fits into 3560 4 times, leaving a remainder of 360.
Put 4 as the next digit of the answer. 
Result so far: 314.0
Subtracting 3200 from 3560 leaves us with 360.
Fetch the next digit (1) from the dividend, attach it to 360 and continue: 3601 / 800

Going ahead to step 7:
3601 divided by 800 is 4 with a remainder of 401.
The number 4 becomes the next digit in our result. 
Result so far: 3144.0
Subtracting 3200 from 3601 leaves us with 401.
Bring next digit (3) of the dividend behind the 401 and repeat the process: 4013 / 800

Let's proceed to step 8:
If we divide 4013 by 800, we get 5 and a remainder of 13.
The next digit of our result is 5. 
Result so far: 31445.0
Subtracting 4000 from 4013 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 9:
800 can be fit into 130 0 times, resulting in a remainder of 130.
The next digit of our result is 0. 
Result so far: 31445.0
Deduct 0 from 130 and we're left with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Let's proceed to step 10:
When dividing 1300 by 800, we get 1 with a remainder of 500.
Use 1 as the next digit of our solution. 
Result so far: 31445.01
Subtract 800 from 1300 to get 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Going ahead to step 11:
When dividing 5000 by 800, we get 6 with a remainder of 200.
Write down 6 as next digit of the result. 
Result so far: 31445.016
Deduct 4800 from 5000 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Advancing to step 12:
The number 800 fits into 2000 2 times, leaving a remainder of 400.
Write down 2 as next digit of the result. 
Result so far: 31445.0162
If we take 1600 away from 2000, we end up with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Going ahead to step 13:
4000 divided by 800 is 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 31445.01625
Deduct 4000 from 4000 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.

Let's proceed to step 14:
When dividing 0 by 800, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 31445.01625
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.

Moving on to step 15:
800 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 31445.01625
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.

The quotient of the division is 31445.01625, and the remainder is 0.0.
