191792 ÷ 21 
We want to divide 191792 by 21.

Advancing to step 1:
If we divide 1 by 21, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 21

Let's proceed to step 2:
19 divided by 21 is 0 with a remainder of 19.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 19 leaves us with 19.
Fetch the next digit (1) from the dividend, attach it to 19 and continue: 191 / 21

Advancing to step 3:
The number 21 fits into 191 9 times, leaving a remainder of 2.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtracting 189 from 191 leaves us with 2.
Include the next digit (7) from the dividend after 2, then repeat: 27 / 21

Let's proceed to step 4:
27 divided by 21 is 1 with a remainder of 6.
Use 1 as the next digit of our solution. 
Result so far: 91.0
If we subtract 21 from 27, we get 6.
Append the next digit (9) from the dividend to 6 and continue with: 69 / 21

Going ahead to step 5:
The number 21 fits into 69 3 times, leaving a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 913.0
If we subtract 63 from 69, we get 6.
Include the next digit (2) from the dividend after 6, then repeat: 62 / 21

On to step 6:
21 goes into 62 2 times with a remainder of 20.
The next digit of our result is 2. 
Result so far: 9132.0
If we subtract 42 from 62, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 7:
If we divide 200 by 21, we get 9 and a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 9132.9
Subtracting 189 from 200 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 8:
If we divide 110 by 21, we get 5 and a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 9132.95
The remainder is 5 after subtracting 105 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 9:
21 goes into 50 2 times with a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 9132.952
The remainder is 8 after subtracting 42 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 10:
If we divide 80 by 21, we get 3 and a remainder of 17.
The next digit of our result is 3. 
Result so far: 9132.9523
Subtract 63 from 80 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 11:
170 divided by 21 is 8 with a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 9132.95238
Subtracting 168 from 170 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 12:
20 divided by 21 is 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 9132.95238
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 13:
If we divide 200 by 21, we get 9 and a remainder of 11.
The next digit of our result is 9. 
Result so far: 9132.9523809
Deduct 189 from 200 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 14:
110 divided by 21 is 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 9132.95238095
The remainder is 5 after subtracting 105 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

In conclusion, the division gives 9132.95238095 with a balance of 5e-09.
