We're dividing 775297 by 21 
Our goal is to divide 775297 by 21.

Advancing to step 1:
21 can be fit into 7 0 times, resulting in a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 21

Advancing to step 2:
If we divide 77 by 21, we get 3 and a remainder of 14.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we subtract 63 from 77, we get 14.
Include the next digit (5) from the dividend after 14, then repeat: 145 / 21

On to step 3:
If we divide 145 by 21, we get 6 and a remainder of 19.
The number 6 becomes the next digit in our result. 
Result so far: 36.0
Subtract 126 from 145 to get 19.
Grab the next digit (2) from the dividend, add it to 19, then carry on: 192 / 21

Advancing to step 4:
The number 21 fits into 192 9 times, leaving a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 369.0
Subtract 189 from 192 to get 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 21

Let's proceed to step 5:
21 can be fit into 39 1 times, resulting in a remainder of 18.
The number 1 becomes the next digit in our result. 
Result so far: 3691.0
The remainder is 18 after subtracting 21 from 39.
Fetch the next digit (7) from the dividend, attach it to 18 and continue: 187 / 21

Let's proceed to step 6:
21 can be fit into 187 8 times, resulting in a remainder of 19.
Write down 8 as next digit of the result. 
Result so far: 36918.0
Subtracting 168 from 187 leaves us 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.

Let's proceed to step 7:
21 can be fit into 190 9 times, resulting in a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 36918.9
Deduct 189 from 190 and we're left 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.

Going ahead to step 8:
21 goes into 10 0 times with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 36918.9
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.

Going ahead to step 9:
21 goes into 100 4 times with a remainder of 16.
The next digit of our result is 4. 
Result so far: 36918.904
Deduct 84 from 100 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 10:
21 goes into 160 7 times with a remainder of 13.
The next digit of our result is 7. 
Result so far: 36918.9047
If we subtract 147 from 160, we 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:
21 goes into 130 6 times with a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 36918.90476
The remainder is 4 after subtracting 126 from 130.
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:
When dividing 40 by 21, we get 1 with a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 36918.904761
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.

Advancing to step 13:
When dividing 190 by 21, we get 9 with a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 36918.9047619
The remainder is 1 after subtracting 189 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 14:
21 goes into 10 0 times with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 36918.9047619
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

After the division, we end up with 36918.9047619 and a remainder of 1e-08.
