We look at the division of 5590899 by 800 
We're looking to find how many times 800 goes into 5590899.

Advancing to step 1:
800 can be fit into 5 0 times, resulting in a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Grab the next digit (5) from the dividend, add it to 5, then carry on: 55 / 800

Advancing to step 2:
800 can be fit into 55 0 times, resulting in a remainder of 55.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 55 and we're left with 55.
Grab the next digit (9) from the dividend, add it to 55, then carry on: 559 / 800

Advancing to step 3:
The number 800 fits into 559 0 times, leaving a remainder of 559.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 559 after subtracting 0 from 559.
Append the next digit (0) from the dividend to 559 and continue with: 5590 / 800

Let's proceed to step 4:
800 goes into 5590 6 times with a remainder of 790.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Subtract 4800 from 5590 to get 790.
Append the next digit (8) from the dividend to 790 and continue with: 7908 / 800

Advancing to step 5:
7908 divided by 800 is 9 with a remainder of 708.
Record the quotient 9 as the next digit in the result. 
Result so far: 69.0
Subtracting 7200 from 7908 leaves us with 708.
Append the next digit (9) from the dividend to 708 and continue with: 7089 / 800

Moving on to step 6:
The number 800 fits into 7089 8 times, leaving a remainder of 689.
Record the quotient 8 as the next digit in the result. 
Result so far: 698.0
If we take 6400 away from 7089, we end up with 689.
Take the next digit (9) from the dividend and append it to 689, then repeat: 6899 / 800

Going ahead to step 7:
800 goes into 6899 8 times with a remainder of 499.
Write down 8 as next digit of the result. 
Result so far: 6988.0
Deduct 6400 from 6899 and we're left with 499.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4990, and continue the process.

Moving on to step 8:
800 can be fit into 4990 6 times, resulting in a remainder of 190.
Put 6 as the next digit of the answer. 
Result so far: 6988.6
Deduct 4800 from 4990 and we're left with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

On to step 9:
If we divide 1900 by 800, we get 2 and a remainder of 300.
Put 2 as the next digit of the answer. 
Result so far: 6988.62
Subtracting 1600 from 1900 leaves us with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Moving on to step 10:
If we divide 3000 by 800, we get 3 and a remainder of 600.
The number 3 becomes the next digit in our result. 
Result so far: 6988.623
If we take 2400 away from 3000, we end up with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Step 11:
If we divide 6000 by 800, we get 7 and a remainder of 400.
Record the quotient 7 as the next digit in the result. 
Result so far: 6988.6237
Deduct 5600 from 6000 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.

Step 12:
The number 800 fits into 4000 5 times, leaving a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 6988.62375
Subtract 4000 from 4000 to 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.

Step 13:
The number 800 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 6988.62375
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.

Moving on to step 14:
800 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 6988.62375
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.

The quotient of the division is 6988.62375, and the remainder is 0.0.
