We're dividing 20125930 by 808 
Let's see how many times 808 fits into 20125930.

On to step 1:
808 can be fit into 2 0 times, resulting in a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 808

Advancing to step 2:
808 can be fit into 20 0 times, resulting in a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 20 leaves us with 20.
Fetch the next digit (1) from the dividend, attach it to 20 and continue: 201 / 808

Let's proceed to step 3:
If we divide 201 by 808, we get 0 and a remainder of 201.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 201, we end up with 201.
Fetch the next digit (2) from the dividend, attach it to 201 and continue: 2012 / 808

Moving on to step 4:
When dividing 2012 by 808, we get 2 with a remainder of 396.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 1616 from 2012 leaves us with 396.
Include the next digit (5) from the dividend after 396, then repeat: 3965 / 808

Let's proceed to step 5:
808 goes into 3965 4 times with a remainder of 733.
Write down 4 as next digit of the result. 
Result so far: 24.0
Subtracting 3232 from 3965 leaves us with 733.
Append the next digit (9) from the dividend to 733 and continue with: 7339 / 808

Let's proceed to step 6:
If we divide 7339 by 808, we get 9 and a remainder of 67.
The number 9 becomes the next digit in our result. 
Result so far: 249.0
Subtract 7272 from 7339 to get 67.
Take the next digit (3) from the dividend and append it to 67, then repeat: 673 / 808

Step 7:
The number 808 fits into 673 0 times, leaving a remainder of 673.
The next digit of our result is 0. 
Result so far: 2490.0
If we subtract 0 from 673, we get 673.
Grab the next digit (0) from the dividend, add it to 673, then carry on: 6730 / 808

On to step 8:
808 goes into 6730 8 times with a remainder of 266.
The number 8 becomes the next digit in our result. 
Result so far: 24908.0
Deduct 6464 from 6730 and we're left with 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

Let's proceed to step 9:
808 can be fit into 2660 3 times, resulting in a remainder of 236.
Record the quotient 3 as the next digit in the result. 
Result so far: 24908.3
Subtract 2424 from 2660 to get 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Moving on to step 10:
When dividing 2360 by 808, we get 2 with a remainder of 744.
The number 2 becomes the next digit in our result. 
Result so far: 24908.32
If we take 1616 away from 2360, we end up with 744.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7440, and continue the process.

Let's proceed to step 11:
808 goes into 7440 9 times with a remainder of 168.
Put 9 as the next digit of the answer. 
Result so far: 24908.329
If we subtract 7272 from 7440, we get 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Let's proceed to step 12:
The number 808 fits into 1680 2 times, leaving a remainder of 64.
Write down 2 as next digit of the result. 
Result so far: 24908.3292
If we subtract 1616 from 1680, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 13:
When dividing 640 by 808, we get 0 with a remainder of 640.
Put 0 as the next digit of the answer. 
Result so far: 24908.3292
If we subtract 0 from 640, we get 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Going ahead to step 14:
6400 divided by 808 is 7 with a remainder of 744.
Record the quotient 7 as the next digit in the result. 
Result so far: 24908.329207
If we subtract 5656 from 6400, we get 744.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7440, and continue the process.

Advancing to step 15:
If we divide 7440 by 808, we get 9 and a remainder of 168.
The next digit of our result is 9. 
Result so far: 24908.3292079
If we subtract 7272 from 7440, we get 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

On to step 16:
If we divide 1680 by 808, we get 2 and a remainder of 64.
The number 2 becomes the next digit in our result. 
Result so far: 24908.32920792
The remainder is 64 after subtracting 1616 from 1680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

After the division, we end up with 24908.32920792 and a remainder of 6.4e-08.
