We divide 20217996 by 807
Our goal is to divide 20217996 by 807.

Let's proceed to step 1:
807 goes into 2 0 times with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 807

Going ahead to step 2:
807 can be fit into 20 0 times, resulting in a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 20 to get 20.
Bring next digit (2) of the dividend behind the 20 and repeat the process: 202 / 807

Advancing to step 3:
202 divided by 807 is 0 with a remainder of 202.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 202 after subtracting 0 from 202.
Take the next digit (1) from the dividend and append it to 202, then repeat: 2021 / 807

Step 4:
807 can be fit into 2021 2 times, resulting in a remainder of 407.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 1614 from 2021 leaves us with 407.
Fetch the next digit (7) from the dividend, attach it to 407 and continue: 4077 / 807

On to step 5:
807 goes into 4077 5 times with a remainder of 42.
Record the quotient 5 as the next digit in the result. 
Result so far: 25.0
Subtracting 4035 from 4077 leaves us with 42.
Fetch the next digit (9) from the dividend, attach it to 42 and continue: 429 / 807

Advancing to step 6:
If we divide 429 by 807, we get 0 and a remainder of 429.
Record the quotient 0 as the next digit in the result. 
Result so far: 250.0
Deduct 0 from 429 and we're left with 429.
Include the next digit (9) from the dividend after 429, then repeat: 4299 / 807

Going ahead to step 7:
807 goes into 4299 5 times with a remainder of 264.
Write down 5 as next digit of the result. 
Result so far: 2505.0
If we subtract 4035 from 4299, we get 264.
Append the next digit (6) from the dividend to 264 and continue with: 2646 / 807

Going ahead to step 8:
2646 divided by 807 is 3 with a remainder of 225.
The number 3 becomes the next digit in our result. 
Result so far: 25053.0
Subtracting 2421 from 2646 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.

Advancing to step 9:
2250 divided by 807 is 2 with a remainder of 636.
Put 2 as the next digit of the answer. 
Result so far: 25053.2
Subtract 1614 from 2250 to get 636.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6360, and continue the process.

Moving on to step 10:
When dividing 6360 by 807, we get 7 with a remainder of 711.
Use 7 as the next digit of our solution. 
Result so far: 25053.27
If we subtract 5649 from 6360, we get 711.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7110, and continue the process.

Going ahead to step 11:
If we divide 7110 by 807, we get 8 and a remainder of 654.
Use 8 as the next digit of our solution. 
Result so far: 25053.278
If we subtract 6456 from 7110, we get 654.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6540, and continue the process.

Moving on to step 12:
The number 807 fits into 6540 8 times, leaving a remainder of 84.
Use 8 as the next digit of our solution. 
Result so far: 25053.2788
If we take 6456 away from 6540, we end up with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

The final result is 25053.2788 with a remainder of 0.00084.
