183794 ÷ 21 
We're looking to find how many times 21 goes into 183794.

Step 1:
1 divided by 21 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 21

Moving on to step 2:
When dividing 18 by 21, we get 0 with a remainder of 18.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 18 after subtracting 0 from 18.
Append the next digit (3) from the dividend to 18 and continue with: 183 / 21

Moving on to step 3:
If we divide 183 by 21, we get 8 and a remainder of 15.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtracting 168 from 183 leaves us with 15.
Bring next digit (7) of the dividend behind the 15 and repeat the process: 157 / 21

Step 4:
When dividing 157 by 21, we get 7 with a remainder of 10.
Write down 7 as next digit of the result. 
Result so far: 87.0
If we subtract 147 from 157, we get 10.
Grab the next digit (9) from the dividend, add it to 10, then carry on: 109 / 21

Step 5:
21 goes into 109 5 times with a remainder of 4.
The number 5 becomes the next digit in our result. 
Result so far: 875.0
Subtracting 105 from 109 leaves us with 4.
Append the next digit (4) from the dividend to 4 and continue with: 44 / 21

Moving on to step 6:
44 divided by 21 is 2 with a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 8752.0
Deduct 42 from 44 and we're left 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 7:
21 goes into 20 0 times with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 8752.0
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.

Step 8:
The number 21 fits into 200 9 times, leaving a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 8752.09
If we subtract 189 from 200, we get 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 9:
21 can be fit into 110 5 times, resulting in a remainder of 5.
The next digit of our result is 5. 
Result so far: 8752.095
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.

Step 10:
If we divide 50 by 21, we get 2 and a remainder of 8.
The next digit of our result is 2. 
Result so far: 8752.0952
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.

On to step 11:
80 divided by 21 is 3 with a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 8752.09523
Subtracting 63 from 80 leaves us 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.

On to step 12:
21 can be fit into 170 8 times, resulting in a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 8752.095238
The remainder is 2 after subtracting 168 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 13:
The number 21 fits into 20 0 times, leaving a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 8752.095238
If we subtract 0 from 20, 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.

Step 14:
When dividing 200 by 21, we get 9 with a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 8752.09523809
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.

The final outcome is 8752.09523809, with a leftover of 1.1e-08.
