We divide 655917 by 21
Let's see how many times 21 fits into 655917.

Advancing to step 1:
The number 21 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (5) from the dividend to 6 and continue with: 65 / 21

Advancing to step 2:
21 goes into 65 3 times with a remainder of 2.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 63 from 65, we get 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 21

On to step 3:
21 goes into 25 1 times with a remainder of 4.
The next digit of our result is 1. 
Result so far: 31.0
Deduct 21 from 25 and we're left with 4.
Include the next digit (9) from the dividend after 4, then repeat: 49 / 21

Going ahead to step 4:
49 divided by 21 is 2 with a remainder of 7.
Use 2 as the next digit of our solution. 
Result so far: 312.0
If we take 42 away from 49, we end up with 7.
Take the next digit (1) from the dividend and append it to 7, then repeat: 71 / 21

Going ahead to step 5:
When dividing 71 by 21, we get 3 with a remainder of 8.
Use 3 as the next digit of our solution. 
Result so far: 3123.0
Deduct 63 from 71 and we're left with 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 21

Moving on to step 6:
The number 21 fits into 87 4 times, leaving a remainder of 3.
Write down 4 as next digit of the result. 
Result so far: 31234.0
Subtract 84 from 87 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 7:
When dividing 30 by 21, we get 1 with a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 31234.1
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.

Step 8:
When dividing 90 by 21, we get 4 with a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 31234.14
Subtracting 84 from 90 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 9:
21 goes into 60 2 times with a remainder of 18.
Use 2 as the next digit of our solution. 
Result so far: 31234.142
If we subtract 42 from 60, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 10:
When dividing 180 by 21, we get 8 with a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 31234.1428
Subtracting 168 from 180 leaves us 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.

Step 11:
120 divided by 21 is 5 with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 31234.14285
Subtracting 105 from 120 leaves us 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.

Advancing to step 12:
21 can be fit into 150 7 times, resulting in a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 31234.142857
Subtract 147 from 150 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 13:
30 divided by 21 is 1 with a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 31234.1428571
Subtracting 21 from 30 leaves us 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 14:
If we divide 90 by 21, we get 4 and a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 31234.14285714
The remainder is 6 after subtracting 84 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

After the division, we end up with 31234.14285714 and a remainder of 6e-09.
