We're dividing 21097562 by 805 
We want to divide 21097562 by 805.

Moving on to step 1:
805 goes into 2 0 times with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 805

Going ahead to step 2:
21 divided by 805 is 0 with a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Bring next digit (0) of the dividend behind the 21 and repeat the process: 210 / 805

Going ahead to step 3:
If we divide 210 by 805, we get 0 and a remainder of 210.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 210, we end up with 210.
Grab the next digit (9) from the dividend, add it to 210, then carry on: 2109 / 805

Let's proceed to step 4:
The number 805 fits into 2109 2 times, leaving a remainder of 499.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 1610 from 2109 to get 499.
Bring next digit (7) of the dividend behind the 499 and repeat the process: 4997 / 805

Going ahead to step 5:
When dividing 4997 by 805, we get 6 with a remainder of 167.
Record the quotient 6 as the next digit in the result. 
Result so far: 26.0
Deduct 4830 from 4997 and we're left with 167.
Bring next digit (5) of the dividend behind the 167 and repeat the process: 1675 / 805

Moving on to step 6:
805 can be fit into 1675 2 times, resulting in a remainder of 65.
The number 2 becomes the next digit in our result. 
Result so far: 262.0
Deduct 1610 from 1675 and we're left with 65.
Include the next digit (6) from the dividend after 65, then repeat: 656 / 805

Step 7:
656 divided by 805 is 0 with a remainder of 656.
The next digit of our result is 0. 
Result so far: 2620.0
If we subtract 0 from 656, we get 656.
Include the next digit (2) from the dividend after 656, then repeat: 6562 / 805

Step 8:
805 can be fit into 6562 8 times, resulting in a remainder of 122.
Write down 8 as next digit of the result. 
Result so far: 26208.0
Deduct 6440 from 6562 and we're left with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Advancing to step 9:
If we divide 1220 by 805, we get 1 and a remainder of 415.
The next digit of our result is 1. 
Result so far: 26208.1
If we subtract 805 from 1220, we get 415.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4150, and continue the process.

Let's proceed to step 10:
If we divide 4150 by 805, we get 5 and a remainder of 125.
The number 5 becomes the next digit in our result. 
Result so far: 26208.15
The remainder is 125 after subtracting 4025 from 4150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Advancing to step 11:
When dividing 1250 by 805, we get 1 with a remainder of 445.
Use 1 as the next digit of our solution. 
Result so far: 26208.151
Subtracting 805 from 1250 leaves us with 445.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4450, and continue the process.

Going ahead to step 12:
If we divide 4450 by 805, we get 5 and a remainder of 425.
Record the quotient 5 as the next digit in the result. 
Result so far: 26208.1515
If we take 4025 away from 4450, we end up with 425.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

Step 13:
If we divide 4250 by 805, we get 5 and a remainder of 225.
Record the quotient 5 as the next digit in the result. 
Result so far: 26208.15155
Subtracting 4025 from 4250 leaves us with 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

After the division, we end up with 26208.15155 and a remainder of 0.000225.
