20178170 ÷ 816 
We want to divide 20178170 by 816.

Going ahead to step 1:
If we divide 2 by 816, we get 0 and a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 816

Let's proceed to step 2:
816 goes into 20 0 times with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 20, we get 20.
Include the next digit (1) from the dividend after 20, then repeat: 201 / 816

Step 3:
If we divide 201 by 816, we get 0 and a remainder of 201.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 201 after subtracting 0 from 201.
Include the next digit (7) from the dividend after 201, then repeat: 2017 / 816

Advancing to step 4:
2017 divided by 816 is 2 with a remainder of 385.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 1632 from 2017, we get 385.
Bring next digit (8) of the dividend behind the 385 and repeat the process: 3858 / 816

Moving on to step 5:
816 goes into 3858 4 times with a remainder of 594.
Put 4 as the next digit of the answer. 
Result so far: 24.0
If we subtract 3264 from 3858, we get 594.
Grab the next digit (1) from the dividend, add it to 594, then carry on: 5941 / 816

On to step 6:
816 can be fit into 5941 7 times, resulting in a remainder of 229.
Write down 7 as next digit of the result. 
Result so far: 247.0
If we subtract 5712 from 5941, we get 229.
Fetch the next digit (7) from the dividend, attach it to 229 and continue: 2297 / 816

Let's proceed to step 7:
816 can be fit into 2297 2 times, resulting in a remainder of 665.
The next digit of our result is 2. 
Result so far: 2472.0
Subtracting 1632 from 2297 leaves us with 665.
Grab the next digit (0) from the dividend, add it to 665, then carry on: 6650 / 816

Advancing to step 8:
When dividing 6650 by 816, we get 8 with a remainder of 122.
Record the quotient 8 as the next digit in the result. 
Result so far: 24728.0
The remainder is 122 after subtracting 6528 from 6650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Going ahead to step 9:
When dividing 1220 by 816, we get 1 with a remainder of 404.
Use 1 as the next digit of our solution. 
Result so far: 24728.1
If we subtract 816 from 1220, we get 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

Advancing to step 10:
816 can be fit into 4040 4 times, resulting in a remainder of 776.
Use 4 as the next digit of our solution. 
Result so far: 24728.14
If we take 3264 away from 4040, we end up with 776.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7760, and continue the process.

Going ahead to step 11:
If we divide 7760 by 816, we get 9 and a remainder of 416.
Use 9 as the next digit of our solution. 
Result so far: 24728.149
Deduct 7344 from 7760 and we're left with 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Advancing to step 12:
The number 816 fits into 4160 5 times, leaving a remainder of 80.
The number 5 becomes the next digit in our result. 
Result so far: 24728.1495
If we subtract 4080 from 4160, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 13:
816 can be fit into 800 0 times, resulting in a remainder of 800.
The number 0 becomes the next digit in our result. 
Result so far: 24728.1495
Subtracting 0 from 800 leaves us with 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

On to step 14:
816 can be fit into 8000 9 times, resulting in a remainder of 656.
Use 9 as the next digit of our solution. 
Result so far: 24728.149509
If we take 7344 away from 8000, we end up with 656.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6560, and continue the process.

Going ahead to step 15:
If we divide 6560 by 816, we get 8 and a remainder of 32.
Use 8 as the next digit of our solution. 
Result so far: 24728.1495098
Subtracting 6528 from 6560 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 16:
When dividing 320 by 816, we get 0 with a remainder of 320.
Record the quotient 0 as the next digit in the result. 
Result so far: 24728.1495098
Subtracting 0 from 320 leaves us with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

The quotient of the division is 24728.1495098, and the remainder is 3.2e-07.
