20598648 ÷ 800 
Let's see how many times 800 fits into 20598648.

Step 1:
800 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
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

Let's proceed to step 2:
800 goes into 20 0 times with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 20 after subtracting 0 from 20.
Fetch the next digit (5) from the dividend, attach it to 20 and continue: 205 / 800

Going ahead to step 3:
The number 800 fits into 205 0 times, leaving a remainder of 205.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 205, we end up with 205.
Fetch the next digit (9) from the dividend, attach it to 205 and continue: 2059 / 800

On to step 4:
800 can be fit into 2059 2 times, resulting in a remainder of 459.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 1600 away from 2059, we end up with 459.
Include the next digit (8) from the dividend after 459, then repeat: 4598 / 800

On to step 5:
If we divide 4598 by 800, we get 5 and a remainder of 598.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
The remainder is 598 after subtracting 4000 from 4598.
Bring next digit (6) of the dividend behind the 598 and repeat the process: 5986 / 800

Moving on to step 6:
5986 divided by 800 is 7 with a remainder of 386.
Use 7 as the next digit of our solution. 
Result so far: 257.0
If we subtract 5600 from 5986, we get 386.
Bring next digit (4) of the dividend behind the 386 and repeat the process: 3864 / 800

Step 7:
800 can be fit into 3864 4 times, resulting in a remainder of 664.
Put 4 as the next digit of the answer. 
Result so far: 2574.0
Subtracting 3200 from 3864 leaves us with 664.
Take the next digit (8) from the dividend and append it to 664, then repeat: 6648 / 800

On to step 8:
6648 divided by 800 is 8 with a remainder of 248.
Write down 8 as next digit of the result. 
Result so far: 25748.0
Deduct 6400 from 6648 and we're left with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Advancing to step 9:
When dividing 2480 by 800, we get 3 with a remainder of 80.
Record the quotient 3 as the next digit in the result. 
Result so far: 25748.3
Subtract 2400 from 2480 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 10:
When dividing 800 by 800, we get 1 with a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 25748.31
The remainder is 0 after subtracting 800 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 11:
800 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 25748.31
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.

Advancing to step 12:
The number 800 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 25748.31
The remainder is 0 after subtracting 0 from 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 25748.31 with a remaining 0.0.
