19805204 divided by 812 
We want to divide 19805204 by 812.

Moving on to step 1:
When dividing 1 by 812, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 812

Let's proceed to step 2:
When dividing 19 by 812, we get 0 with a remainder of 19.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 19, we get 19.
Include the next digit (8) from the dividend after 19, then repeat: 198 / 812

Advancing to step 3:
If we divide 198 by 812, we get 0 and a remainder of 198.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 198, we get 198.
Append the next digit (0) from the dividend to 198 and continue with: 1980 / 812

Going ahead to step 4:
The number 812 fits into 1980 2 times, leaving a remainder of 356.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 1624 from 1980 leaves us with 356.
Fetch the next digit (5) from the dividend, attach it to 356 and continue: 3565 / 812

On to step 5:
When dividing 3565 by 812, we get 4 with a remainder of 317.
The number 4 becomes the next digit in our result. 
Result so far: 24.0
If we take 3248 away from 3565, we end up with 317.
Append the next digit (2) from the dividend to 317 and continue with: 3172 / 812

Going ahead to step 6:
812 can be fit into 3172 3 times, resulting in a remainder of 736.
Use 3 as the next digit of our solution. 
Result so far: 243.0
If we subtract 2436 from 3172, we get 736.
Grab the next digit (0) from the dividend, add it to 736, then carry on: 7360 / 812

Advancing to step 7:
The number 812 fits into 7360 9 times, leaving a remainder of 52.
The number 9 becomes the next digit in our result. 
Result so far: 2439.0
If we subtract 7308 from 7360, we get 52.
Include the next digit (4) from the dividend after 52, then repeat: 524 / 812

Let's proceed to step 8:
If we divide 524 by 812, we get 0 and a remainder of 524.
The number 0 becomes the next digit in our result. 
Result so far: 24390.0
Subtract 0 from 524 to get 524.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5240, and continue the process.

Moving on to step 9:
812 goes into 5240 6 times with a remainder of 368.
The number 6 becomes the next digit in our result. 
Result so far: 24390.6
If we take 4872 away from 5240, we end up with 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Advancing to step 10:
812 can be fit into 3680 4 times, resulting in a remainder of 432.
The number 4 becomes the next digit in our result. 
Result so far: 24390.64
If we subtract 3248 from 3680, we get 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

Moving on to step 11:
812 can be fit into 4320 5 times, resulting in a remainder of 260.
The number 5 becomes the next digit in our result. 
Result so far: 24390.645
If we subtract 4060 from 4320, we get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Going ahead to step 12:
2600 divided by 812 is 3 with a remainder of 164.
The number 3 becomes the next digit in our result. 
Result so far: 24390.6453
Subtract 2436 from 2600 to get 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

On to step 13:
If we divide 1640 by 812, we get 2 and a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 24390.64532
Subtract 1624 from 1640 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 14:
The number 812 fits into 160 0 times, leaving a remainder of 160.
Use 0 as the next digit of our solution. 
Result so far: 24390.64532
The remainder is 160 after subtracting 0 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Moving on to step 15:
1600 divided by 812 is 1 with a remainder of 788.
Write down 1 as next digit of the result. 
Result so far: 24390.6453201
Deduct 812 from 1600 and we're left with 788.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7880, and continue the process.

Going ahead to step 16:
The number 812 fits into 7880 9 times, leaving a remainder of 572.
Put 9 as the next digit of the answer. 
Result so far: 24390.64532019
If we subtract 7308 from 7880, we get 572.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5720, and continue the process.

The final outcome is 24390.64532019, with a leftover of 5.72e-07.
