We divide 842468 by 21
Let's see how many times 21 fits into 842468.

Let's proceed to step 1:
When dividing 8 by 21, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 21

Moving on to step 2:
The number 21 fits into 84 4 times, leaving a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtracting 84 from 84 leaves us with 0.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 21

Step 3:
21 can be fit into 2 0 times, resulting in a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 40.0
Subtract 0 from 2 to get 2.
Fetch the next digit (4) from the dividend, attach it to 2 and continue: 24 / 21

Going ahead to step 4:
24 divided by 21 is 1 with a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 401.0
Subtracting 21 from 24 leaves us with 3.
Include the next digit (6) from the dividend after 3, then repeat: 36 / 21

Going ahead to step 5:
If we divide 36 by 21, we get 1 and a remainder of 15.
Write down 1 as next digit of the result. 
Result so far: 4011.0
Deduct 21 from 36 and we're left with 15.
Append the next digit (8) from the dividend to 15 and continue with: 158 / 21

Let's proceed to step 6:
21 goes into 158 7 times with a remainder of 11.
The next digit of our result is 7. 
Result so far: 40117.0
Subtracting 147 from 158 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:
21 can be fit into 110 5 times, resulting in a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 40117.5
If we subtract 105 from 110, 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.

Advancing to step 8:
21 can be fit into 50 2 times, resulting in a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 40117.52
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.

Going ahead to step 9:
21 can be fit into 80 3 times, resulting in a remainder of 17.
Use 3 as the next digit of our solution. 
Result so far: 40117.523
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.

Going ahead to step 10:
21 goes into 170 8 times with a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 40117.5238
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.

Step 11:
If we divide 20 by 21, we get 0 and a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 40117.5238
Subtract 0 from 20 to 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.

Let's proceed to step 12:
21 goes into 200 9 times with a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 40117.523809
Subtract 189 from 200 to 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.

Advancing to step 13:
110 divided by 21 is 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 40117.5238095
If we subtract 105 from 110, 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.

Let's proceed to step 14:
50 divided by 21 is 2 with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 40117.52380952
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.

Our division results in 40117.52380952 with a remaining 8e-09.
