We look at the division of 21729666 by 773 
Let's see how many times 773 fits into 21729666.

Going ahead to step 1:
773 can be fit into 2 0 times, resulting in a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 773

Going ahead to step 2:
The number 773 fits into 21 0 times, leaving a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Include the next digit (7) from the dividend after 21, then repeat: 217 / 773

On to step 3:
If we divide 217 by 773, we get 0 and a remainder of 217.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 217 after subtracting 0 from 217.
Fetch the next digit (2) from the dividend, attach it to 217 and continue: 2172 / 773

Moving on to step 4:
2172 divided by 773 is 2 with a remainder of 626.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 1546 from 2172, we get 626.
Grab the next digit (9) from the dividend, add it to 626, then carry on: 6269 / 773

Going ahead to step 5:
The number 773 fits into 6269 8 times, leaving a remainder of 85.
The number 8 becomes the next digit in our result. 
Result so far: 28.0
Deduct 6184 from 6269 and we're left with 85.
Bring next digit (6) of the dividend behind the 85 and repeat the process: 856 / 773

On to step 6:
If we divide 856 by 773, we get 1 and a remainder of 83.
Use 1 as the next digit of our solution. 
Result so far: 281.0
Subtracting 773 from 856 leaves us with 83.
Fetch the next digit (6) from the dividend, attach it to 83 and continue: 836 / 773

Let's proceed to step 7:
The number 773 fits into 836 1 times, leaving a remainder of 63.
The next digit of our result is 1. 
Result so far: 2811.0
Subtract 773 from 836 to get 63.
Fetch the next digit (6) from the dividend, attach it to 63 and continue: 636 / 773

Advancing to step 8:
If we divide 636 by 773, we get 0 and a remainder of 636.
Record the quotient 0 as the next digit in the result. 
Result so far: 28110.0
Subtract 0 from 636 to get 636.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6360, and continue the process.

Advancing to step 9:
773 can be fit into 6360 8 times, resulting in a remainder of 176.
Write down 8 as next digit of the result. 
Result so far: 28110.8
Subtracting 6184 from 6360 leaves us with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Advancing to step 10:
If we divide 1760 by 773, we get 2 and a remainder of 214.
Put 2 as the next digit of the answer. 
Result so far: 28110.82
If we subtract 1546 from 1760, we get 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Let's proceed to step 11:
When dividing 2140 by 773, we get 2 with a remainder of 594.
The next digit of our result is 2. 
Result so far: 28110.822
The remainder is 594 after subtracting 1546 from 2140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5940, and continue the process.

The quotient of the division is 28110.822, and the remainder is 0.0594.
