775549 divided by 21 
We want to divide 775549 by 21.

Advancing to step 1:
The number 21 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 21

Going ahead to step 2:
If we divide 77 by 21, we get 3 and a remainder of 14.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
The remainder is 14 after subtracting 63 from 77.
Bring next digit (5) of the dividend behind the 14 and repeat the process: 145 / 21

Going ahead to step 3:
145 divided by 21 is 6 with a remainder of 19.
Record the quotient 6 as the next digit in the result. 
Result so far: 36.0
If we subtract 126 from 145, we get 19.
Append the next digit (5) from the dividend to 19 and continue with: 195 / 21

Going ahead to step 4:
21 goes into 195 9 times with a remainder of 6.
The next digit of our result is 9. 
Result so far: 369.0
The remainder is 6 after subtracting 189 from 195.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 21

Let's proceed to step 5:
When dividing 64 by 21, we get 3 with a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 3693.0
Subtracting 63 from 64 leaves us with 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 21

Advancing to step 6:
21 goes into 19 0 times with a remainder of 19.
The next digit of our result is 0. 
Result so far: 36930.0
Subtract 0 from 19 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 7:
If we divide 190 by 21, we get 9 and a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 36930.9
If we take 189 away from 190, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 8:
If we divide 10 by 21, we get 0 and a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 36930.9
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 9:
The number 21 fits into 100 4 times, leaving a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 36930.904
Subtract 84 from 100 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 10:
When dividing 160 by 21, we get 7 with a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 36930.9047
Subtract 147 from 160 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 11:
When dividing 130 by 21, we get 6 with a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 36930.90476
Subtract 126 from 130 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 12:
21 can be fit into 40 1 times, resulting in a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 36930.904761
If we take 21 away from 40, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 13:
190 divided by 21 is 9 with a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 36930.9047619
Subtracting 189 from 190 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 14:
10 divided by 21 is 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 36930.9047619
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final result is 36930.9047619 with a remainder of 1e-08.
