Let's divide 653956 by 21
Our goal is to divide 653956 by 21.

Going ahead to step 1:
6 divided by 21 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (5) from the dividend, attach it to 6 and continue: 65 / 21

Advancing to step 2:
21 goes into 65 3 times with a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 2 after subtracting 63 from 65.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 21

Let's proceed to step 3:
The number 21 fits into 23 1 times, leaving a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 31.0
If we subtract 21 from 23, we get 2.
Grab the next digit (9) from the dividend, add it to 2, then carry on: 29 / 21

Advancing to step 4:
21 goes into 29 1 times with a remainder of 8.
The next digit of our result is 1. 
Result so far: 311.0
If we take 21 away from 29, we end up with 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 21

Going ahead to step 5:
21 goes into 85 4 times with a remainder of 1.
The next digit of our result is 4. 
Result so far: 3114.0
The remainder is 1 after subtracting 84 from 85.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 21

Step 6:
21 can be fit into 16 0 times, resulting in a remainder of 16.
Put 0 as the next digit of the answer. 
Result so far: 31140.0
Subtracting 0 from 16 leaves us 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 7:
21 goes into 160 7 times with a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 31140.7
Subtracting 147 from 160 leaves us 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.

On to step 8:
When dividing 130 by 21, we get 6 with a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 31140.76
Deduct 126 from 130 and we're left 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.

On to step 9:
When dividing 40 by 21, we get 1 with a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 31140.761
Subtract 21 from 40 to 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 10:
The number 21 fits into 190 9 times, leaving a remainder of 1.
The next digit of our result is 9. 
Result so far: 31140.7619
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.

Step 11:
21 goes into 10 0 times with a remainder of 10.
The next digit of our result is 0. 
Result so far: 31140.7619
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.

On to step 12:
The number 21 fits into 100 4 times, leaving a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 31140.761904
The remainder is 16 after subtracting 84 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 13:
160 divided by 21 is 7 with a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 31140.7619047
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.

Going ahead to step 14:
21 can be fit into 130 6 times, resulting in a remainder of 4.
The next digit of our result is 6. 
Result so far: 31140.76190476
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.

The final result is 31140.76190476 with a remainder of 4e-09.
