We divide 814189 by 21
We're looking to find how many times 21 goes into 814189.

Advancing to step 1:
21 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 21

Going ahead to step 2:
If we divide 81 by 21, we get 3 and a remainder of 18.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 63 away from 81, we end up with 18.
Include the next digit (4) from the dividend after 18, then repeat: 184 / 21

Advancing to step 3:
The number 21 fits into 184 8 times, leaving a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 38.0
The remainder is 16 after subtracting 168 from 184.
Append the next digit (1) from the dividend to 16 and continue with: 161 / 21

Going ahead to step 4:
The number 21 fits into 161 7 times, leaving a remainder of 14.
Record the quotient 7 as the next digit in the result. 
Result so far: 387.0
If we subtract 147 from 161, we get 14.
Fetch the next digit (8) from the dividend, attach it to 14 and continue: 148 / 21

Going ahead to step 5:
The number 21 fits into 148 7 times, leaving a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 3877.0
The remainder is 1 after subtracting 147 from 148.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 21

Step 6:
If we divide 19 by 21, we get 0 and a remainder of 19.
The next digit of our result is 0. 
Result so far: 38770.0
If we subtract 0 from 19, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 7:
21 goes into 190 9 times with a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 38770.9
The remainder is 1 after subtracting 189 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 8:
When dividing 10 by 21, we get 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 38770.9
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.

Advancing to step 9:
100 divided by 21 is 4 with a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 38770.904
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.

Step 10:
21 can be fit into 160 7 times, resulting in a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 38770.9047
Deduct 147 from 160 and we're left with 13.
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:
130 divided by 21 is 6 with a remainder of 4.
The next digit of our result is 6. 
Result so far: 38770.90476
If we take 126 away from 130, we end up 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.

Step 12:
21 goes into 40 1 times with a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 38770.904761
If we subtract 21 from 40, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 13:
21 goes into 190 9 times with a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 38770.9047619
Subtract 189 from 190 to 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.

On to step 14:
The number 21 fits into 10 0 times, leaving a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 38770.9047619
If we take 0 away from 10, we end up 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.

Our division results in 38770.9047619 with a remaining 1e-08.
