Let's divide 21772729 by 816
We're looking to find how many times 816 goes into 21772729.

Step 1:
816 goes into 2 0 times with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 816

Let's proceed to step 2:
816 goes into 21 0 times with a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Append the next digit (7) from the dividend to 21 and continue with: 217 / 816

Step 3:
The number 816 fits into 217 0 times, leaving a remainder of 217.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 217 and we're left with 217.
Include the next digit (7) from the dividend after 217, then repeat: 2177 / 816

Going ahead to step 4:
If we divide 2177 by 816, we get 2 and a remainder of 545.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 545 after subtracting 1632 from 2177.
Take the next digit (2) from the dividend and append it to 545, then repeat: 5452 / 816

Going ahead to step 5:
816 can be fit into 5452 6 times, resulting in a remainder of 556.
The next digit of our result is 6. 
Result so far: 26.0
Deduct 4896 from 5452 and we're left with 556.
Include the next digit (7) from the dividend after 556, then repeat: 5567 / 816

Step 6:
When dividing 5567 by 816, we get 6 with a remainder of 671.
Write down 6 as next digit of the result. 
Result so far: 266.0
Subtract 4896 from 5567 to get 671.
Bring next digit (2) of the dividend behind the 671 and repeat the process: 6712 / 816

Moving on to step 7:
When dividing 6712 by 816, we get 8 with a remainder of 184.
Write down 8 as next digit of the result. 
Result so far: 2668.0
If we take 6528 away from 6712, we end up with 184.
Take the next digit (9) from the dividend and append it to 184, then repeat: 1849 / 816

On to step 8:
When dividing 1849 by 816, we get 2 with a remainder of 217.
Record the quotient 2 as the next digit in the result. 
Result so far: 26682.0
Subtracting 1632 from 1849 leaves us with 217.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2170, and continue the process.

Moving on to step 9:
816 can be fit into 2170 2 times, resulting in a remainder of 538.
Record the quotient 2 as the next digit in the result. 
Result so far: 26682.2
If we take 1632 away from 2170, we end up with 538.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5380, and continue the process.

Going ahead to step 10:
816 can be fit into 5380 6 times, resulting in a remainder of 484.
Use 6 as the next digit of our solution. 
Result so far: 26682.26
The remainder is 484 after subtracting 4896 from 5380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4840, and continue the process.

Advancing to step 11:
If we divide 4840 by 816, we get 5 and a remainder of 760.
The next digit of our result is 5. 
Result so far: 26682.265
Deduct 4080 from 4840 and we're left with 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

Let's proceed to step 12:
816 goes into 7600 9 times with a remainder of 256.
Use 9 as the next digit of our solution. 
Result so far: 26682.2659
Deduct 7344 from 7600 and we're left with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Step 13:
2560 divided by 816 is 3 with a remainder of 112.
The number 3 becomes the next digit in our result. 
Result so far: 26682.26593
Subtracting 2448 from 2560 leaves us with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Moving on to step 14:
If we divide 1120 by 816, we get 1 and a remainder of 304.
The next digit of our result is 1. 
Result so far: 26682.265931
The remainder is 304 after subtracting 816 from 1120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Step 15:
The number 816 fits into 3040 3 times, leaving a remainder of 592.
Record the quotient 3 as the next digit in the result. 
Result so far: 26682.2659313
If we subtract 2448 from 3040, we get 592.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5920, and continue the process.

Step 16:
If we divide 5920 by 816, we get 7 and a remainder of 208.
Put 7 as the next digit of the answer. 
Result so far: 26682.26593137
Deduct 5712 from 5920 and we're left with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

The quotient of the division is 26682.26593137, and the remainder is 2.08e-07.
