800900 divided by 55 
Our goal is to divide 800900 by 55.

Advancing to step 1:
8 divided by 55 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 55

On to step 2:
If we divide 80 by 55, we get 1 and a remainder of 25.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 55 from 80 leaves us with 25.
Grab the next digit (0) from the dividend, add it to 25, then carry on: 250 / 55

On to step 3:
The number 55 fits into 250 4 times, leaving a remainder of 30.
Write down 4 as next digit of the result. 
Result so far: 14.0
Deduct 220 from 250 and we're left with 30.
Fetch the next digit (9) from the dividend, attach it to 30 and continue: 309 / 55

On to step 4:
309 divided by 55 is 5 with a remainder of 34.
Record the quotient 5 as the next digit in the result. 
Result so far: 145.0
The remainder is 34 after subtracting 275 from 309.
Append the next digit (0) from the dividend to 34 and continue with: 340 / 55

Step 5:
If we divide 340 by 55, we get 6 and a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 1456.0
If we take 330 away from 340, we end up with 10.
Include the next digit (0) from the dividend after 10, then repeat: 100 / 55

Moving on to step 6:
55 can be fit into 100 1 times, resulting in a remainder of 45.
The number 1 becomes the next digit in our result. 
Result so far: 14561.0
The remainder is 45 after subtracting 55 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 7:
55 can be fit into 450 8 times, resulting in a remainder of 10.
Use 8 as the next digit of our solution. 
Result so far: 14561.8
If we take 440 away from 450, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
The number 55 fits into 100 1 times, leaving a remainder of 45.
Put 1 as the next digit of the answer. 
Result so far: 14561.81
If we subtract 55 from 100, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 9:
If we divide 450 by 55, we get 8 and a remainder of 10.
Record the quotient 8 as the next digit in the result. 
Result so far: 14561.818
The remainder is 10 after subtracting 440 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 10:
55 goes into 100 1 times with a remainder of 45.
The number 1 becomes the next digit in our result. 
Result so far: 14561.8181
If we take 55 away from 100, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 11:
If we divide 450 by 55, we get 8 and a remainder of 10.
Put 8 as the next digit of the answer. 
Result so far: 14561.81818
Subtracting 440 from 450 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 12:
100 divided by 55 is 1 with a remainder of 45.
The number 1 becomes the next digit in our result. 
Result so far: 14561.818181
Deduct 55 from 100 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 13:
55 goes into 450 8 times with a remainder of 10.
Write down 8 as next digit of the result. 
Result so far: 14561.8181818
If we subtract 440 from 450, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 14:
When dividing 100 by 55, we get 1 with a remainder of 45.
The number 1 becomes the next digit in our result. 
Result so far: 14561.81818181
Subtracting 55 from 100 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

The final result is 14561.81818181 with a remainder of 4.5e-08.
