We're dividing 21636368 by 805 
Our goal is to divide 21636368 by 805.

Step 1:
805 can be fit into 2 0 times, resulting in a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 805

Moving on to step 2:
If we divide 21 by 805, we get 0 and a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Bring next digit (6) of the dividend behind the 21 and repeat the process: 216 / 805

Moving on to step 3:
805 can be fit into 216 0 times, resulting in a remainder of 216.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 216 and we're left with 216.
Append the next digit (3) from the dividend to 216 and continue with: 2163 / 805

Let's proceed to step 4:
If we divide 2163 by 805, we get 2 and a remainder of 553.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 1610 from 2163 to get 553.
Bring next digit (6) of the dividend behind the 553 and repeat the process: 5536 / 805

Moving on to step 5:
When dividing 5536 by 805, we get 6 with a remainder of 706.
The number 6 becomes the next digit in our result. 
Result so far: 26.0
Subtract 4830 from 5536 to get 706.
Fetch the next digit (3) from the dividend, attach it to 706 and continue: 7063 / 805

On to step 6:
805 can be fit into 7063 8 times, resulting in a remainder of 623.
The number 8 becomes the next digit in our result. 
Result so far: 268.0
Subtract 6440 from 7063 to get 623.
Bring next digit (6) of the dividend behind the 623 and repeat the process: 6236 / 805

Moving on to step 7:
When dividing 6236 by 805, we get 7 with a remainder of 601.
Use 7 as the next digit of our solution. 
Result so far: 2687.0
Deduct 5635 from 6236 and we're left with 601.
Include the next digit (8) from the dividend after 601, then repeat: 6018 / 805

Going ahead to step 8:
805 goes into 6018 7 times with a remainder of 383.
Record the quotient 7 as the next digit in the result. 
Result so far: 26877.0
Subtract 5635 from 6018 to get 383.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3830, and continue the process.

Going ahead to step 9:
805 goes into 3830 4 times with a remainder of 610.
Write down 4 as next digit of the result. 
Result so far: 26877.4
If we take 3220 away from 3830, we end up with 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

On to step 10:
If we divide 6100 by 805, we get 7 and a remainder of 465.
Record the quotient 7 as the next digit in the result. 
Result so far: 26877.47
If we take 5635 away from 6100, we end up with 465.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4650, and continue the process.

Step 11:
805 goes into 4650 5 times with a remainder of 625.
Record the quotient 5 as the next digit in the result. 
Result so far: 26877.475
If we subtract 4025 from 4650, we get 625.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6250, and continue the process.

Moving on to step 12:
805 goes into 6250 7 times with a remainder of 615.
Use 7 as the next digit of our solution. 
Result so far: 26877.4757
Subtract 5635 from 6250 to get 615.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6150, and continue the process.

Let's proceed to step 13:
805 goes into 6150 7 times with a remainder of 515.
Record the quotient 7 as the next digit in the result. 
Result so far: 26877.47577
Deduct 5635 from 6150 and we're left with 515.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5150, and continue the process.

The final result is 26877.47577 with a remainder of 0.000515.
