Let's divide 802113 by 21
Our goal is to divide 802113 by 21.

Step 1:
21 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 21

Moving on to step 2:
The number 21 fits into 80 3 times, leaving 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.
Append the next digit (2) from the dividend to 17 and continue with: 172 / 21

On to step 3:
The number 21 fits into 172 8 times, leaving a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 38.0
The remainder is 4 after subtracting 168 from 172.
Fetch the next digit (1) from the dividend, attach it to 4 and continue: 41 / 21

Advancing to step 4:
The number 21 fits into 41 1 times, leaving a remainder of 20.
Put 1 as the next digit of the answer. 
Result so far: 381.0
The remainder is 20 after subtracting 21 from 41.
Grab the next digit (1) from the dividend, add it to 20, then carry on: 201 / 21

Moving on to step 5:
The number 21 fits into 201 9 times, leaving a remainder of 12.
Put 9 as the next digit of the answer. 
Result so far: 3819.0
Subtract 189 from 201 to get 12.
Bring next digit (3) of the dividend behind the 12 and repeat the process: 123 / 21

Going ahead to step 6:
21 goes into 123 5 times with a remainder of 18.
Write down 5 as next digit of the result. 
Result so far: 38195.0
Subtracting 105 from 123 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 7:
21 goes into 180 8 times with a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 38195.8
Subtracting 168 from 180 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 8:
120 divided by 21 is 5 with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 38195.85
If we subtract 105 from 120, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 9:
The number 21 fits into 150 7 times, leaving a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 38195.857
Subtract 147 from 150 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 10:
21 goes into 30 1 times with a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 38195.8571
Subtracting 21 from 30 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 11:
When dividing 90 by 21, we get 4 with a remainder of 6.
The next digit of our result is 4. 
Result so far: 38195.85714
If we subtract 84 from 90, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 12:
The number 21 fits into 60 2 times, leaving a remainder of 18.
Use 2 as the next digit of our solution. 
Result so far: 38195.857142
Subtracting 42 from 60 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 13:
When dividing 180 by 21, we get 8 with a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 38195.8571428
Subtract 168 from 180 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 14:
21 goes into 120 5 times with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 38195.85714285
Subtracting 105 from 120 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Our division results in 38195.85714285 with a remaining 1.5e-08.
