We're dividing 1841 by 21 
We want to divide 1841 by 21.

Moving on to step 1:
If we divide 1 by 21, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 21

Advancing to step 2:
18 divided by 21 is 0 with a remainder of 18.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 18, we get 18.
Include the next digit (4) from the dividend after 18, then repeat: 184 / 21

Moving on to step 3:
The number 21 fits into 184 8 times, leaving a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtracting 168 from 184 leaves us with 16.
Grab the next digit (1) from the dividend, add it to 16, then carry on: 161 / 21

Moving on to step 4:
21 can be fit into 161 7 times, resulting in a remainder of 14.
The number 7 becomes the next digit in our result. 
Result so far: 87.0
If we subtract 147 from 161, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 5:
140 divided by 21 is 6 with a remainder of 14.
The next digit of our result is 6. 
Result so far: 87.6
Subtracting 126 from 140 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 6:
21 can be fit into 140 6 times, resulting in a remainder of 14.
Write down 6 as next digit of the result. 
Result so far: 87.66
Subtract 126 from 140 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The final result is 87.66 with a remainder of 0.014.
