We divide 25683264 by 20
We want to divide 25683264 by 20.

On to step 1:
The number 20 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 20

Going ahead to step 2:
If we divide 25 by 20, we get 1 and a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 20 away from 25, we end up with 5.
Append the next digit (6) from the dividend to 5 and continue with: 56 / 20

Advancing to step 3:
20 goes into 56 2 times with a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 12.0
Deduct 40 from 56 and we're left with 16.
Append the next digit (8) from the dividend to 16 and continue with: 168 / 20

On to step 4:
20 goes into 168 8 times with a remainder of 8.
The next digit of our result is 8. 
Result so far: 128.0
Subtract 160 from 168 to get 8.
Fetch the next digit (3) from the dividend, attach it to 8 and continue: 83 / 20

On to step 5:
If we divide 83 by 20, we get 4 and a remainder of 3.
Record the quotient 4 as the next digit in the result. 
Result so far: 1284.0
Subtract 80 from 83 to get 3.
Grab the next digit (2) from the dividend, add it to 3, then carry on: 32 / 20

Moving on to step 6:
32 divided by 20 is 1 with a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 12841.0
If we subtract 20 from 32, we get 12.
Append the next digit (6) from the dividend to 12 and continue with: 126 / 20

Going ahead to step 7:
The number 20 fits into 126 6 times, leaving a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 128416.0
Subtracting 120 from 126 leaves us with 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 20

Advancing to step 8:
The number 20 fits into 64 3 times, leaving a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 1284163.0
The remainder is 4 after subtracting 60 from 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 9:
The number 20 fits into 40 2 times, leaving a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 1284163.2
Deduct 40 from 40 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 10:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 1284163.2
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 11:
If we divide 0 by 20, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 1284163.2
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 1284163.2, with a leftover of 0.0.
