848655 divided by 21 
Our goal is to divide 848655 by 21.

On to 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
Subtract 0 from 8 to get 8.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 21

Moving on to step 2:
The number 21 fits into 84 4 times, leaving a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtracting 84 from 84 leaves us with 0.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 21

Moving on to step 3:
8 divided by 21 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 40.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 21

Moving on to step 4:
The number 21 fits into 86 4 times, leaving a remainder of 2.
The next digit of our result is 4. 
Result so far: 404.0
Subtract 84 from 86 to get 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 21

Moving on to step 5:
25 divided by 21 is 1 with a remainder of 4.
The next digit of our result is 1. 
Result so far: 4041.0
If we subtract 21 from 25, we get 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 21

Step 6:
The number 21 fits into 45 2 times, leaving a remainder of 3.
Write down 2 as next digit of the result. 
Result so far: 40412.0
Subtracting 42 from 45 leaves us with 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 7:
21 can be fit into 30 1 times, resulting in a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 40412.1
If we take 21 away from 30, we end up 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.

Moving on to step 8:
21 can be fit into 90 4 times, resulting in a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 40412.14
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.

Step 9:
60 divided by 21 is 2 with a remainder of 18.
Use 2 as the next digit of our solution. 
Result so far: 40412.142
Deduct 42 from 60 and we're left 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 10:
21 goes into 180 8 times with a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 40412.1428
Deduct 168 from 180 and we're left 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.

Moving on to step 11:
120 divided by 21 is 5 with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 40412.14285
Deduct 105 from 120 and we're left 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.

Going ahead to step 12:
The number 21 fits into 150 7 times, leaving a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 40412.142857
If we take 147 away from 150, we end up with 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 13:
When dividing 30 by 21, we get 1 with a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 40412.1428571
The remainder is 9 after subtracting 21 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 14:
The number 21 fits into 90 4 times, leaving a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 40412.14285714
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.

In conclusion, the division gives 40412.14285714 with a balance of 6e-09.
