Let's divide 191741 by 21
We're looking to find how many times 21 goes into 191741.

Step 1:
21 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 21

Step 2:
21 goes into 19 0 times with a remainder of 19.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 19 after subtracting 0 from 19.
Include the next digit (1) from the dividend after 19, then repeat: 191 / 21

Moving on to step 3:
If we divide 191 by 21, we get 9 and a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Deduct 189 from 191 and we're left with 2.
Grab the next digit (7) from the dividend, add it to 2, then carry on: 27 / 21

Advancing to step 4:
When dividing 27 by 21, we get 1 with a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 91.0
The remainder is 6 after subtracting 21 from 27.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 21

On to step 5:
21 goes into 64 3 times with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 913.0
The remainder is 1 after subtracting 63 from 64.
Append the next digit (1) from the dividend to 1 and continue with: 11 / 21

Step 6:
11 divided by 21 is 0 with a remainder of 11.
Write down 0 as next digit of the result. 
Result so far: 9130.0
Subtracting 0 from 11 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.

Step 7:
If we divide 110 by 21, we get 5 and a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 9130.5
Subtracting 105 from 110 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 8:
The number 21 fits into 50 2 times, leaving a remainder of 8.
The next digit of our result is 2. 
Result so far: 9130.52
If we take 42 away from 50, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 9:
If we divide 80 by 21, we get 3 and a remainder of 17.
The number 3 becomes the next digit in our result. 
Result so far: 9130.523
If we take 63 away from 80, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 10:
21 can be fit into 170 8 times, resulting in a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 9130.5238
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.

On to step 11:
20 divided by 21 is 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 9130.5238
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 12:
21 can be fit into 200 9 times, resulting in a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 9130.523809
The remainder is 11 after subtracting 189 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 13:
21 can be fit into 110 5 times, resulting in a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 9130.5238095
Deduct 105 from 110 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 14:
21 goes into 50 2 times with a remainder of 8.
The next digit of our result is 2. 
Result so far: 9130.52380952
Subtracting 42 from 50 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

In conclusion, the division gives 9130.52380952 with a balance of 8e-09.
