269679 divided by 21 
Our goal is to divide 269679 by 21.

Advancing to step 1:
21 can be fit into 2 0 times, resulting in a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Bring next digit (6) of the dividend behind the 2 and repeat the process: 26 / 21

Let's proceed to step 2:
When dividing 26 by 21, we get 1 with a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 5 after subtracting 21 from 26.
Append the next digit (9) from the dividend to 5 and continue with: 59 / 21

Step 3:
If we divide 59 by 21, we get 2 and a remainder of 17.
Write down 2 as next digit of the result. 
Result so far: 12.0
The remainder is 17 after subtracting 42 from 59.
Bring next digit (6) of the dividend behind the 17 and repeat the process: 176 / 21

Moving on to step 4:
The number 21 fits into 176 8 times, leaving a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 128.0
Deduct 168 from 176 and we're left with 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 21

Let's proceed to step 5:
87 divided by 21 is 4 with a remainder of 3.
Record the quotient 4 as the next digit in the result. 
Result so far: 1284.0
Deduct 84 from 87 and we're left with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 21

On to step 6:
21 goes into 39 1 times with a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 12841.0
Deduct 21 from 39 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.

On to step 7:
When dividing 180 by 21, we get 8 with a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 12841.8
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 8:
The number 21 fits into 120 5 times, leaving a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 12841.85
If we take 105 away from 120, we end up 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.

Let's proceed to step 9:
21 goes into 150 7 times with a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 12841.857
The remainder is 3 after subtracting 147 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 10:
30 divided by 21 is 1 with a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 12841.8571
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.

Let's proceed to step 11:
The number 21 fits into 90 4 times, leaving a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 12841.85714
Subtract 84 from 90 to 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.

Let's proceed to step 12:
If we divide 60 by 21, we get 2 and a remainder of 18.
The next digit of our result is 2. 
Result so far: 12841.857142
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.

Going ahead to step 13:
When dividing 180 by 21, we get 8 with a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 12841.8571428
If we subtract 168 from 180, we get 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 14:
21 can be fit into 120 5 times, resulting in a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 12841.85714285
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.

The final result is 12841.85714285 with a remainder of 1.5e-08.
