Let's divide 20193986 by 819
We're looking to find how many times 819 goes into 20193986.

Let's proceed to step 1:
When dividing 2 by 819, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 819

Going ahead to step 2:
819 goes into 20 0 times with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 20 after subtracting 0 from 20.
Fetch the next digit (1) from the dividend, attach it to 20 and continue: 201 / 819

Going ahead to step 3:
819 can be fit into 201 0 times, resulting in a remainder of 201.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 201, we get 201.
Take the next digit (9) from the dividend and append it to 201, then repeat: 2019 / 819

Step 4:
2019 divided by 819 is 2 with a remainder of 381.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 1638 from 2019, we get 381.
Take the next digit (3) from the dividend and append it to 381, then repeat: 3813 / 819

Advancing to step 5:
3813 divided by 819 is 4 with a remainder of 537.
The number 4 becomes the next digit in our result. 
Result so far: 24.0
The remainder is 537 after subtracting 3276 from 3813.
Bring next digit (9) of the dividend behind the 537 and repeat the process: 5379 / 819

Moving on to step 6:
819 goes into 5379 6 times with a remainder of 465.
Use 6 as the next digit of our solution. 
Result so far: 246.0
Subtracting 4914 from 5379 leaves us with 465.
Grab the next digit (8) from the dividend, add it to 465, then carry on: 4658 / 819

On to step 7:
The number 819 fits into 4658 5 times, leaving a remainder of 563.
Record the quotient 5 as the next digit in the result. 
Result so far: 2465.0
Subtract 4095 from 4658 to get 563.
Include the next digit (6) from the dividend after 563, then repeat: 5636 / 819

On to step 8:
The number 819 fits into 5636 6 times, leaving a remainder of 722.
Use 6 as the next digit of our solution. 
Result so far: 24656.0
The remainder is 722 after subtracting 4914 from 5636.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7220, and continue the process.

Advancing to step 9:
7220 divided by 819 is 8 with a remainder of 668.
The number 8 becomes the next digit in our result. 
Result so far: 24656.8
If we take 6552 away from 7220, we end up with 668.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6680, and continue the process.

Step 10:
6680 divided by 819 is 8 with a remainder of 128.
Use 8 as the next digit of our solution. 
Result so far: 24656.88
If we subtract 6552 from 6680, we get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

The final outcome is 24656.88, with a leftover of 0.128.
