We divide 69585 by 21
We're looking to find how many times 21 goes into 69585.

Advancing to step 1:
6 divided by 21 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Bring next digit (9) of the dividend behind the 6 and repeat the process: 69 / 21

Step 2:
69 divided by 21 is 3 with a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtracting 63 from 69 leaves us with 6.
Take the next digit (5) from the dividend and append it to 6, then repeat: 65 / 21

Going ahead to step 3:
The number 21 fits into 65 3 times, leaving a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 33.0
If we take 63 away from 65, we end up with 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 21

Advancing to step 4:
28 divided by 21 is 1 with a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 331.0
If we take 21 away from 28, we end up with 7.
Append the next digit (5) from the dividend to 7 and continue with: 75 / 21

Step 5:
21 goes into 75 3 times with a remainder of 12.
Use 3 as the next digit of our solution. 
Result so far: 3313.0
Deduct 63 from 75 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.

Step 6:
21 can be fit into 120 5 times, resulting in a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 3313.5
Subtract 105 from 120 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 7:
The number 21 fits into 150 7 times, leaving a remainder of 3.
The next digit of our result is 7. 
Result so far: 3313.57
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.

Step 8:
21 can be fit into 30 1 times, resulting in a remainder of 9.
The next digit of our result is 1. 
Result so far: 3313.571
Subtract 21 from 30 to get 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 9:
If we divide 90 by 21, we get 4 and a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 3313.5714
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 10:
60 divided by 21 is 2 with a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 3313.57142
Subtract 42 from 60 to 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 11:
21 can be fit into 180 8 times, resulting in a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 3313.571428
If we take 168 away from 180, we end up 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.

Let's proceed to step 12:
When dividing 120 by 21, we get 5 with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 3313.5714285
If we subtract 105 from 120, we get 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 13:
150 divided by 21 is 7 with a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 3313.57142857
Subtracting 147 from 150 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.

The final outcome is 3313.57142857, with a leftover of 3e-09.
