We're dividing 20008439 by 812 
Let's see how many times 812 fits into 20008439.

Moving on to step 1:
The number 812 fits into 2 0 times, leaving a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 812

On to step 2:
812 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
If we subtract 0 from 20, we get 20.
Bring next digit (0) of the dividend behind the 20 and repeat the process: 200 / 812

Let's proceed to step 3:
812 can be fit into 200 0 times, resulting in a remainder of 200.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 200, we get 200.
Fetch the next digit (0) from the dividend, attach it to 200 and continue: 2000 / 812

Let's proceed to step 4:
812 can be fit into 2000 2 times, resulting in a remainder of 376.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 376 after subtracting 1624 from 2000.
Take the next digit (8) from the dividend and append it to 376, then repeat: 3768 / 812

Going ahead to step 5:
3768 divided by 812 is 4 with a remainder of 520.
Put 4 as the next digit of the answer. 
Result so far: 24.0
Subtracting 3248 from 3768 leaves us with 520.
Append the next digit (4) from the dividend to 520 and continue with: 5204 / 812

Advancing to step 6:
812 can be fit into 5204 6 times, resulting in a remainder of 332.
Record the quotient 6 as the next digit in the result. 
Result so far: 246.0
Subtracting 4872 from 5204 leaves us with 332.
Fetch the next digit (3) from the dividend, attach it to 332 and continue: 3323 / 812

Going ahead to step 7:
812 can be fit into 3323 4 times, resulting in a remainder of 75.
The next digit of our result is 4. 
Result so far: 2464.0
If we subtract 3248 from 3323, we get 75.
Grab the next digit (9) from the dividend, add it to 75, then carry on: 759 / 812

Advancing to step 8:
812 can be fit into 759 0 times, resulting in a remainder of 759.
The number 0 becomes the next digit in our result. 
Result so far: 24640.0
If we subtract 0 from 759, we get 759.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7590, and continue the process.

Let's proceed to step 9:
812 goes into 7590 9 times with a remainder of 282.
Use 9 as the next digit of our solution. 
Result so far: 24640.9
Deduct 7308 from 7590 and we're left with 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

On to step 10:
2820 divided by 812 is 3 with a remainder of 384.
Write down 3 as next digit of the result. 
Result so far: 24640.93
The remainder is 384 after subtracting 2436 from 2820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Moving on to step 11:
The number 812 fits into 3840 4 times, leaving a remainder of 592.
Write down 4 as next digit of the result. 
Result so far: 24640.934
If we take 3248 away from 3840, we end up with 592.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5920, and continue the process.

Moving on to step 12:
The number 812 fits into 5920 7 times, leaving a remainder of 236.
The next digit of our result is 7. 
Result so far: 24640.9347
Deduct 5684 from 5920 and we're left with 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Step 13:
2360 divided by 812 is 2 with a remainder of 736.
Record the quotient 2 as the next digit in the result. 
Result so far: 24640.93472
If we take 1624 away from 2360, we end up with 736.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7360, and continue the process.

Step 14:
When dividing 7360 by 812, we get 9 with a remainder of 52.
Record the quotient 9 as the next digit in the result. 
Result so far: 24640.934729
If we subtract 7308 from 7360, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 15:
812 can be fit into 520 0 times, resulting in a remainder of 520.
Put 0 as the next digit of the answer. 
Result so far: 24640.934729
Subtract 0 from 520 to get 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

On to step 16:
5200 divided by 812 is 6 with a remainder of 328.
Put 6 as the next digit of the answer. 
Result so far: 24640.93472906
Deduct 4872 from 5200 and we're left with 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

The final outcome is 24640.93472906, with a leftover of 3.28e-07.
