We're dividing 763326 by 21 
Let's see how many times 21 fits into 763326.

On to step 1:
If we divide 7 by 21, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Include the next digit (6) from the dividend after 7, then repeat: 76 / 21

Advancing to step 2:
21 goes into 76 3 times with a remainder of 13.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we take 63 away from 76, we end up with 13.
Fetch the next digit (3) from the dividend, attach it to 13 and continue: 133 / 21

Let's proceed to step 3:
When dividing 133 by 21, we get 6 with a remainder of 7.
Record the quotient 6 as the next digit in the result. 
Result so far: 36.0
If we subtract 126 from 133, we get 7.
Take the next digit (3) from the dividend and append it to 7, then repeat: 73 / 21

Step 4:
21 goes into 73 3 times with a remainder of 10.
Put 3 as the next digit of the answer. 
Result so far: 363.0
If we subtract 63 from 73, we get 10.
Append the next digit (2) from the dividend to 10 and continue with: 102 / 21

Let's proceed to step 5:
21 can be fit into 102 4 times, resulting in a remainder of 18.
The next digit of our result is 4. 
Result so far: 3634.0
Deduct 84 from 102 and we're left with 18.
Fetch the next digit (6) from the dividend, attach it to 18 and continue: 186 / 21

Going ahead to step 6:
21 can be fit into 186 8 times, resulting in a remainder of 18.
Record the quotient 8 as the next digit in the result. 
Result so far: 36348.0
Deduct 168 from 186 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 7:
21 goes into 180 8 times with a remainder of 12.
The next digit of our result is 8. 
Result so far: 36348.8
If we take 168 away from 180, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 8:
When dividing 120 by 21, we get 5 with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 36348.85
Subtract 105 from 120 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 9:
21 goes into 150 7 times with a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 36348.857
Subtracting 147 from 150 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 10:
21 goes into 30 1 times with a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 36348.8571
Deduct 21 from 30 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 11:
90 divided by 21 is 4 with a remainder of 6.
The next digit of our result is 4. 
Result so far: 36348.85714
Deduct 84 from 90 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 12:
If we divide 60 by 21, we get 2 and a remainder of 18.
The next digit of our result is 2. 
Result so far: 36348.857142
If we subtract 42 from 60, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 13:
21 goes into 180 8 times with a remainder of 12.
The next digit of our result is 8. 
Result so far: 36348.8571428
Subtract 168 from 180 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 14:
The number 21 fits into 120 5 times, leaving a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 36348.85714285
Deduct 105 from 120 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The final result is 36348.85714285 with a remainder of 1.5e-08.
