We divide 838801 by 21
Our goal is to divide 838801 by 21.

Let's proceed to step 1:
8 divided by 21 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 21

Going ahead to step 2:
21 can be fit into 83 3 times, resulting in a remainder of 20.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Deduct 63 from 83 and we're left with 20.
Fetch the next digit (8) from the dividend, attach it to 20 and continue: 208 / 21

Let's proceed to step 3:
21 can be fit into 208 9 times, resulting in a remainder of 19.
Record the quotient 9 as the next digit in the result. 
Result so far: 39.0
Deduct 189 from 208 and we're left with 19.
Append the next digit (8) from the dividend to 19 and continue with: 198 / 21

Moving on to step 4:
If we divide 198 by 21, we get 9 and a remainder of 9.
Use 9 as the next digit of our solution. 
Result so far: 399.0
Deduct 189 from 198 and we're left with 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 21

Let's proceed to step 5:
The number 21 fits into 90 4 times, leaving a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 3994.0
The remainder is 6 after subtracting 84 from 90.
Take the next digit (1) from the dividend and append it to 6, then repeat: 61 / 21

Going ahead to step 6:
If we divide 61 by 21, we get 2 and a remainder of 19.
The number 2 becomes the next digit in our result. 
Result so far: 39942.0
Deduct 42 from 61 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.

On to step 7:
21 goes into 190 9 times with a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 39942.9
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.

Let's proceed to step 8:
The number 21 fits into 10 0 times, leaving a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 39942.9
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 9:
100 divided by 21 is 4 with a remainder of 16.
The next digit of our result is 4. 
Result so far: 39942.904
Deduct 84 from 100 and we're left 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.

Let's proceed to step 10:
21 goes into 160 7 times with a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 39942.9047
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 11:
When dividing 130 by 21, we get 6 with a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 39942.90476
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.

Step 12:
40 divided by 21 is 1 with a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 39942.904761
If we take 21 away from 40, we end up 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 13:
If we divide 190 by 21, we get 9 and a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 39942.9047619
If we subtract 189 from 190, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 14:
If we divide 10 by 21, we get 0 and a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 39942.9047619
Subtract 0 from 10 to 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.

Our division results in 39942.9047619 with a remaining 1e-08.
