Let's divide 841118 by 21
Let's see how many times 21 fits into 841118.

Going ahead to step 1:
8 divided by 21 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 21

Moving on to step 2:
84 divided by 21 is 4 with a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtracting 84 from 84 leaves us with 0.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 21

Going ahead to step 3:
21 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 40.0
If we subtract 0 from 1, we get 1.
Grab the next digit (1) from the dividend, add it to 1, then carry on: 11 / 21

Moving on to step 4:
If we divide 11 by 21, we get 0 and a remainder of 11.
The number 0 becomes the next digit in our result. 
Result so far: 400.0
If we take 0 away from 11, we end up with 11.
Fetch the next digit (1) from the dividend, attach it to 11 and continue: 111 / 21

Going ahead to step 5:
When dividing 111 by 21, we get 5 with a remainder of 6.
Record the quotient 5 as the next digit in the result. 
Result so far: 4005.0
If we subtract 105 from 111, we get 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 21

Advancing to step 6:
21 goes into 68 3 times with a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 40053.0
If we subtract 63 from 68, we get 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 7:
The number 21 fits into 50 2 times, leaving a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 40053.2
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.

Going ahead to step 8:
80 divided by 21 is 3 with a remainder of 17.
Record the quotient 3 as the next digit in the result. 
Result so far: 40053.23
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.

Step 9:
When dividing 170 by 21, we get 8 with a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 40053.238
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.

Advancing to step 10:
20 divided by 21 is 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 40053.238
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.

Moving on to step 11:
21 can be fit into 200 9 times, resulting in a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 40053.23809
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.

Step 12:
21 can be fit into 110 5 times, resulting in a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 40053.238095
Subtract 105 from 110 to get 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 13:
When dividing 50 by 21, we get 2 with a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 40053.2380952
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.

Going ahead to step 14:
21 can be fit into 80 3 times, resulting in a remainder of 17.
Record the quotient 3 as the next digit in the result. 
Result so far: 40053.23809523
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.

The final outcome is 40053.23809523, with a leftover of 1.7e-08.
