Let's divide 192369 by 21
We want to divide 192369 by 21.

On to step 1:
The number 21 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 21

Let's proceed to step 2:
If we divide 19 by 21, we get 0 and a remainder of 19.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 19 after subtracting 0 from 19.
Include the next digit (2) from the dividend after 19, then repeat: 192 / 21

Step 3:
If we divide 192 by 21, we get 9 and a remainder of 3.
The next digit of our result is 9. 
Result so far: 9.0
Subtract 189 from 192 to get 3.
Grab the next digit (3) from the dividend, add it to 3, then carry on: 33 / 21

Let's proceed to step 4:
33 divided by 21 is 1 with a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 91.0
Subtract 21 from 33 to get 12.
Bring next digit (6) of the dividend behind the 12 and repeat the process: 126 / 21

On to step 5:
The number 21 fits into 126 6 times, leaving a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 916.0
If we take 126 away from 126, we end up with 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 21

Going ahead to step 6:
When dividing 9 by 21, we get 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 9160.0
If we subtract 0 from 9, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 7:
21 can be fit into 90 4 times, resulting in a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 9160.4
Subtract 84 from 90 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 8:
The number 21 fits into 60 2 times, leaving a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 9160.42
If we take 42 away from 60, we end up 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.

Going ahead to step 9:
180 divided by 21 is 8 with a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 9160.428
Subtracting 168 from 180 leaves us 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.

Step 10:
21 can be fit into 120 5 times, resulting in a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 9160.4285
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.

Moving on to step 11:
The number 21 fits into 150 7 times, leaving a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 9160.42857
If we subtract 147 from 150, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 12:
The number 21 fits into 30 1 times, leaving a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 9160.428571
The remainder is 9 after subtracting 21 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 13:
21 goes into 90 4 times with a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 9160.4285714
The remainder is 6 after subtracting 84 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 14:
The number 21 fits into 60 2 times, leaving a remainder of 18.
Record the quotient 2 as the next digit in the result. 
Result so far: 9160.42857142
Subtracting 42 from 60 leaves us 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.

The quotient of the division is 9160.42857142, and the remainder is 1.8e-08.
