We divide 20403650 by 807
We want to figure out the number of times 20403650 can be divided by 807.

Advancing to step 1:
2 divided by 807 is 0 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

Let's proceed to step 2:
The number 807 fits into 20 0 times, leaving a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 20, we end up with 20.
Append the next digit (4) from the dividend to 20 and continue with: 204 / 807

Moving on to step 3:
When dividing 204 by 807, we get 0 with a remainder of 204.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 204 leaves us with 204.
Bring next digit (0) of the dividend behind the 204 and repeat the process: 2040 / 807

On to step 4:
When dividing 2040 by 807, we get 2 with a remainder of 426.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 1614 away from 2040, we end up with 426.
Include the next digit (3) from the dividend after 426, then repeat: 4263 / 807

Advancing to step 5:
If we divide 4263 by 807, we get 5 and a remainder of 228.
Put 5 as the next digit of the answer. 
Result so far: 25.0
If we subtract 4035 from 4263, we get 228.
Take the next digit (6) from the dividend and append it to 228, then repeat: 2286 / 807

Advancing to step 6:
The number 807 fits into 2286 2 times, leaving a remainder of 672.
The number 2 becomes the next digit in our result. 
Result so far: 252.0
Deduct 1614 from 2286 and we're left with 672.
Include the next digit (5) from the dividend after 672, then repeat: 6725 / 807

Advancing to step 7:
807 can be fit into 6725 8 times, resulting in a remainder of 269.
Use 8 as the next digit of our solution. 
Result so far: 2528.0
If we take 6456 away from 6725, we end up with 269.
Include the next digit (0) from the dividend after 269, then repeat: 2690 / 807

On to step 8:
If we divide 2690 by 807, we get 3 and a remainder of 269.
Use 3 as the next digit of our solution. 
Result so far: 25283.0
If we subtract 2421 from 2690, we get 269.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2690, and continue the process.

Going ahead to step 9:
2690 divided by 807 is 3 with a remainder of 269.
Write down 3 as next digit of the result. 
Result so far: 25283.3
Deduct 2421 from 2690 and we're left with 269.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2690, and continue the process.

On to step 10:
The number 807 fits into 2690 3 times, leaving a remainder of 269.
The next digit of our result is 3. 
Result so far: 25283.33
Subtracting 2421 from 2690 leaves us with 269.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2690, and continue the process.

Our division results in 25283.33 with a remaining 0.269.
