16203133 ÷ 811 
We want to divide 16203133 by 811.

Step 1:
When dividing 1 by 811, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 811

On to step 2:
When dividing 16 by 811, we get 0 with a remainder of 16.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 16, we get 16.
Include the next digit (2) from the dividend after 16, then repeat: 162 / 811

Moving on to step 3:
811 goes into 162 0 times with a remainder of 162.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 162 leaves us with 162.
Include the next digit (0) from the dividend after 162, then repeat: 1620 / 811

Step 4:
If we divide 1620 by 811, we get 1 and a remainder of 809.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 811 from 1620 to get 809.
Take the next digit (3) from the dividend and append it to 809, then repeat: 8093 / 811

On to step 5:
When dividing 8093 by 811, we get 9 with a remainder of 794.
The next digit of our result is 9. 
Result so far: 19.0
Deduct 7299 from 8093 and we're left with 794.
Grab the next digit (1) from the dividend, add it to 794, then carry on: 7941 / 811

Step 6:
When dividing 7941 by 811, we get 9 with a remainder of 642.
Put 9 as the next digit of the answer. 
Result so far: 199.0
If we subtract 7299 from 7941, we get 642.
Include the next digit (3) from the dividend after 642, then repeat: 6423 / 811

Moving on to step 7:
When dividing 6423 by 811, we get 7 with a remainder of 746.
The next digit of our result is 7. 
Result so far: 1997.0
Subtract 5677 from 6423 to get 746.
Take the next digit (3) from the dividend and append it to 746, then repeat: 7463 / 811

Let's proceed to step 8:
7463 divided by 811 is 9 with a remainder of 164.
The next digit of our result is 9. 
Result so far: 19979.0
Subtract 7299 from 7463 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 9:
The number 811 fits into 1640 2 times, leaving a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 19979.2
If we subtract 1622 from 1640, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 10:
811 can be fit into 180 0 times, resulting in a remainder of 180.
Record the quotient 0 as the next digit in the result. 
Result so far: 19979.2
Subtracting 0 from 180 leaves us with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Step 11:
811 can be fit into 1800 2 times, resulting in a remainder of 178.
Record the quotient 2 as the next digit in the result. 
Result so far: 19979.202
If we take 1622 away from 1800, we end up with 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

Moving on to step 12:
The number 811 fits into 1780 2 times, leaving a remainder of 158.
Use 2 as the next digit of our solution. 
Result so far: 19979.2022
Deduct 1622 from 1780 and we're left with 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Our division results in 19979.2022 with a remaining 0.00158.
