We divide 820595 by 21
Our goal is to divide 820595 by 21.

Step 1:
8 divided by 21 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (2) from the dividend, add it to 8, then carry on: 82 / 21

Let's proceed to step 2:
The number 21 fits into 82 3 times, leaving a remainder of 19.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtracting 63 from 82 leaves us with 19.
Take the next digit (0) from the dividend and append it to 19, then repeat: 190 / 21

Going ahead to step 3:
When dividing 190 by 21, we get 9 with a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 39.0
Subtract 189 from 190 to get 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 21

Going ahead to step 4:
When dividing 15 by 21, we get 0 with a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 390.0
If we subtract 0 from 15, we get 15.
Fetch the next digit (9) from the dividend, attach it to 15 and continue: 159 / 21

Let's proceed to step 5:
If we divide 159 by 21, we get 7 and a remainder of 12.
The next digit of our result is 7. 
Result so far: 3907.0
Subtracting 147 from 159 leaves us with 12.
Take the next digit (5) from the dividend and append it to 12, then repeat: 125 / 21

Advancing to step 6:
125 divided by 21 is 5 with a remainder of 20.
The next digit of our result is 5. 
Result so far: 39075.0
Subtracting 105 from 125 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 7:
200 divided by 21 is 9 with a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 39075.9
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.

Going ahead to step 8:
The number 21 fits into 110 5 times, leaving a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 39075.95
If we take 105 away from 110, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 9:
50 divided by 21 is 2 with a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 39075.952
If we subtract 42 from 50, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 10:
The number 21 fits into 80 3 times, leaving a remainder of 17.
The number 3 becomes the next digit in our result. 
Result so far: 39075.9523
Subtracting 63 from 80 leaves us 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.

Advancing to step 11:
21 goes into 170 8 times with a remainder of 2.
The next digit of our result is 8. 
Result so far: 39075.95238
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.

Let's proceed to step 12:
21 goes into 20 0 times with a remainder of 20.
The next digit of our result is 0. 
Result so far: 39075.95238
If we take 0 away from 20, we end up with 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 13:
200 divided by 21 is 9 with a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 39075.9523809
If we subtract 189 from 200, we 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.

Moving on to step 14:
When dividing 110 by 21, we get 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 39075.95238095
Subtracting 105 from 110 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Our division results in 39075.95238095 with a remaining 5e-09.
