We're dividing 19793740 by 811 
Let's see how many times 811 fits into 19793740.

On to step 1:
811 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 811

On to step 2:
When dividing 19 by 811, we get 0 with a remainder of 19.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 19 to get 19.
Include the next digit (7) from the dividend after 19, then repeat: 197 / 811

Going ahead to step 3:
If we divide 197 by 811, we get 0 and a remainder of 197.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 197, we end up with 197.
Fetch the next digit (9) from the dividend, attach it to 197 and continue: 1979 / 811

On to step 4:
If we divide 1979 by 811, we get 2 and a remainder of 357.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 1622 from 1979 leaves us with 357.
Bring next digit (3) of the dividend behind the 357 and repeat the process: 3573 / 811

On to step 5:
811 can be fit into 3573 4 times, resulting in a remainder of 329.
The number 4 becomes the next digit in our result. 
Result so far: 24.0
If we subtract 3244 from 3573, we get 329.
Take the next digit (7) from the dividend and append it to 329, then repeat: 3297 / 811

Going ahead to step 6:
When dividing 3297 by 811, we get 4 with a remainder of 53.
Record the quotient 4 as the next digit in the result. 
Result so far: 244.0
Deduct 3244 from 3297 and we're left with 53.
Take the next digit (4) from the dividend and append it to 53, then repeat: 534 / 811

Step 7:
If we divide 534 by 811, we get 0 and a remainder of 534.
The next digit of our result is 0. 
Result so far: 2440.0
If we subtract 0 from 534, we get 534.
Include the next digit (0) from the dividend after 534, then repeat: 5340 / 811

Moving on to step 8:
811 goes into 5340 6 times with a remainder of 474.
Put 6 as the next digit of the answer. 
Result so far: 24406.0
Deduct 4866 from 5340 and we're left with 474.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4740, and continue the process.

Moving on to step 9:
811 can be fit into 4740 5 times, resulting in a remainder of 685.
Record the quotient 5 as the next digit in the result. 
Result so far: 24406.5
Subtracting 4055 from 4740 leaves us with 685.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6850, and continue the process.

Going ahead to step 10:
811 can be fit into 6850 8 times, resulting in a remainder of 362.
Write down 8 as next digit of the result. 
Result so far: 24406.58
If we take 6488 away from 6850, we end up with 362.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

Moving on to step 11:
811 can be fit into 3620 4 times, resulting in a remainder of 376.
The next digit of our result is 4. 
Result so far: 24406.584
If we take 3244 away from 3620, we end up with 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Let's proceed to step 12:
The number 811 fits into 3760 4 times, leaving a remainder of 516.
The next digit of our result is 4. 
Result so far: 24406.5844
Subtracting 3244 from 3760 leaves us with 516.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5160, and continue the process.

The quotient of the division is 24406.5844, and the remainder is 0.00516.
