We're dividing 81759521 by 900 
Our goal is to divide 81759521 by 900.

Advancing to step 1:
900 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 900

Step 2:
900 goes into 81 0 times with a remainder of 81.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 81, we get 81.
Include the next digit (7) from the dividend after 81, then repeat: 817 / 900

Let's proceed to step 3:
The number 900 fits into 817 0 times, leaving a remainder of 817.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 817 and we're left with 817.
Append the next digit (5) from the dividend to 817 and continue with: 8175 / 900

Let's proceed to step 4:
If we divide 8175 by 900, we get 9 and a remainder of 75.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
The remainder is 75 after subtracting 8100 from 8175.
Grab the next digit (9) from the dividend, add it to 75, then carry on: 759 / 900

Advancing to step 5:
If we divide 759 by 900, we get 0 and a remainder of 759.
The next digit of our result is 0. 
Result so far: 90.0
Subtracting 0 from 759 leaves us with 759.
Bring next digit (5) of the dividend behind the 759 and repeat the process: 7595 / 900

On to step 6:
If we divide 7595 by 900, we get 8 and a remainder of 395.
Put 8 as the next digit of the answer. 
Result so far: 908.0
The remainder is 395 after subtracting 7200 from 7595.
Take the next digit (2) from the dividend and append it to 395, then repeat: 3952 / 900

Going ahead to step 7:
The number 900 fits into 3952 4 times, leaving a remainder of 352.
The number 4 becomes the next digit in our result. 
Result so far: 9084.0
Subtracting 3600 from 3952 leaves us with 352.
Bring next digit (1) of the dividend behind the 352 and repeat the process: 3521 / 900

Advancing to step 8:
If we divide 3521 by 900, we get 3 and a remainder of 821.
Use 3 as the next digit of our solution. 
Result so far: 90843.0
Subtracting 2700 from 3521 leaves us with 821.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8210, and continue the process.

Going ahead to step 9:
900 can be fit into 8210 9 times, resulting in a remainder of 110.
Use 9 as the next digit of our solution. 
Result so far: 90843.9
Subtracting 8100 from 8210 leaves us with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Moving on to step 10:
900 can be fit into 1100 1 times, resulting in a remainder of 200.
Record the quotient 1 as the next digit in the result. 
Result so far: 90843.91
If we subtract 900 from 1100, 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.

On to step 11:
2000 divided by 900 is 2 with a remainder of 200.
The number 2 becomes the next digit in our result. 
Result so far: 90843.912
Subtracting 1800 from 2000 leaves us 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.

Moving on to step 12:
If we divide 2000 by 900, we get 2 and a remainder of 200.
Record the quotient 2 as the next digit in the result. 
Result so far: 90843.9122
If we subtract 1800 from 2000, 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.

After the division, we end up with 90843.9122 and a remainder of 0.002.
