We look at the division of 802846 by 21 
We're looking to find how many times 21 goes into 802846.

Step 1:
8 divided by 21 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 21

Going ahead to step 2:
When dividing 80 by 21, we get 3 with a remainder of 17.
The next digit of our result is 3. 
Result so far: 3.0
The remainder is 17 after subtracting 63 from 80.
Fetch the next digit (2) from the dividend, attach it to 17 and continue: 172 / 21

Let's proceed to step 3:
172 divided by 21 is 8 with a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 38.0
If we subtract 168 from 172, we get 4.
Bring next digit (8) of the dividend behind the 4 and repeat the process: 48 / 21

Going ahead to step 4:
When dividing 48 by 21, we get 2 with a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 382.0
Deduct 42 from 48 and we're left with 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 21

Let's proceed to step 5:
When dividing 64 by 21, we get 3 with a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 3823.0
If we subtract 63 from 64, we get 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 21

On to step 6:
21 goes into 16 0 times with a remainder of 16.
The number 0 becomes the next digit in our result. 
Result so far: 38230.0
Subtract 0 from 16 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 7:
When dividing 160 by 21, we get 7 with a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 38230.7
Subtract 147 from 160 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 8:
When dividing 130 by 21, we get 6 with a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 38230.76
Deduct 126 from 130 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 9:
The number 21 fits into 40 1 times, leaving a remainder of 19.
The next digit of our result is 1. 
Result so far: 38230.761
Deduct 21 from 40 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 10:
21 goes into 190 9 times with a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 38230.7619
Deduct 189 from 190 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 11:
The number 21 fits into 10 0 times, leaving a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 38230.7619
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 12:
100 divided by 21 is 4 with a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 38230.761904
Subtracting 84 from 100 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 13:
The number 21 fits into 160 7 times, leaving a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 38230.7619047
The remainder is 13 after subtracting 147 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 14:
21 goes into 130 6 times with a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 38230.76190476
If we subtract 126 from 130, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final result is 38230.76190476 with a remainder of 4e-09.
