We divide 55224578 by 800
Let's see how many times 800 fits into 55224578.

Step 1:
800 goes into 5 0 times with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Bring next digit (5) of the dividend behind the 5 and repeat the process: 55 / 800

Step 2:
55 divided by 800 is 0 with a remainder of 55.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 55 leaves us with 55.
Append the next digit (2) from the dividend to 55 and continue with: 552 / 800

Going ahead to step 3:
552 divided by 800 is 0 with a remainder of 552.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 552, we get 552.
Take the next digit (2) from the dividend and append it to 552, then repeat: 5522 / 800

Going ahead to step 4:
5522 divided by 800 is 6 with a remainder of 722.
Use 6 as the next digit of our solution. 
Result so far: 6.0
If we subtract 4800 from 5522, we get 722.
Fetch the next digit (4) from the dividend, attach it to 722 and continue: 7224 / 800

Going ahead to step 5:
7224 divided by 800 is 9 with a remainder of 24.
Record the quotient 9 as the next digit in the result. 
Result so far: 69.0
Deduct 7200 from 7224 and we're left with 24.
Include the next digit (5) from the dividend after 24, then repeat: 245 / 800

Let's proceed to step 6:
If we divide 245 by 800, we get 0 and a remainder of 245.
The next digit of our result is 0. 
Result so far: 690.0
The remainder is 245 after subtracting 0 from 245.
Bring next digit (7) of the dividend behind the 245 and repeat the process: 2457 / 800

Going ahead to step 7:
If we divide 2457 by 800, we get 3 and a remainder of 57.
Record the quotient 3 as the next digit in the result. 
Result so far: 6903.0
Subtracting 2400 from 2457 leaves us with 57.
Bring next digit (8) of the dividend behind the 57 and repeat the process: 578 / 800

Moving on to step 8:
800 goes into 578 0 times with a remainder of 578.
Use 0 as the next digit of our solution. 
Result so far: 69030.0
If we subtract 0 from 578, we get 578.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5780, and continue the process.

Moving on to step 9:
If we divide 5780 by 800, we get 7 and a remainder of 180.
The number 7 becomes the next digit in our result. 
Result so far: 69030.7
Subtract 5600 from 5780 to get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Advancing to step 10:
If we divide 1800 by 800, we get 2 and a remainder of 200.
Use 2 as the next digit of our solution. 
Result so far: 69030.72
If we subtract 1600 from 1800, 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.

Step 11:
2000 divided by 800 is 2 with a remainder of 400.
Write down 2 as next digit of the result. 
Result so far: 69030.722
Deduct 1600 from 2000 and we're left 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.

The quotient of the division is 69030.722, and the remainder is 0.04.
