We look at the division of 761922 by 21 
Our goal is to divide 761922 by 21.

On to step 1:
If we divide 7 by 21, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (6) from the dividend, add it to 7, then carry on: 76 / 21

Let's proceed to step 2:
21 can be fit into 76 3 times, resulting in a remainder of 13.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we subtract 63 from 76, we get 13.
Bring next digit (1) of the dividend behind the 13 and repeat the process: 131 / 21

Moving on to step 3:
21 can be fit into 131 6 times, resulting in a remainder of 5.
Put 6 as the next digit of the answer. 
Result so far: 36.0
If we take 126 away from 131, we end up with 5.
Include the next digit (9) from the dividend after 5, then repeat: 59 / 21

Advancing to step 4:
21 goes into 59 2 times with a remainder of 17.
The next digit of our result is 2. 
Result so far: 362.0
If we take 42 away from 59, we end up with 17.
Take the next digit (2) from the dividend and append it to 17, then repeat: 172 / 21

Let's proceed to step 5:
If we divide 172 by 21, we get 8 and a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 3628.0
Deduct 168 from 172 and we're left with 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 21

Step 6:
21 goes into 42 2 times with a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 36282.0
Subtract 42 from 42 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 7:
When dividing 0 by 21, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 36282.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 8:
The number 21 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 36282.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 36282.0 and a remainder of 0.0.
