We divide 311385 by 21
We're looking to find how many times 21 goes into 311385.

Advancing to step 1:
If we divide 3 by 21, we get 0 and a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 21

Let's proceed to step 2:
31 divided by 21 is 1 with a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 10 after subtracting 21 from 31.
Take the next digit (1) from the dividend and append it to 10, then repeat: 101 / 21

Moving on to step 3:
When dividing 101 by 21, we get 4 with a remainder of 17.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
Deduct 84 from 101 and we're left with 17.
Append the next digit (3) from the dividend to 17 and continue with: 173 / 21

Going ahead to step 4:
21 can be fit into 173 8 times, resulting in a remainder of 5.
The next digit of our result is 8. 
Result so far: 148.0
Deduct 168 from 173 and we're left with 5.
Grab the next digit (8) from the dividend, add it to 5, then carry on: 58 / 21

Step 5:
The number 21 fits into 58 2 times, leaving a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 1482.0
If we take 42 away from 58, we end up with 16.
Grab the next digit (5) from the dividend, add it to 16, then carry on: 165 / 21

Moving on to step 6:
When dividing 165 by 21, we get 7 with a remainder of 18.
The number 7 becomes the next digit in our result. 
Result so far: 14827.0
Deduct 147 from 165 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.
The number 8 becomes the next digit in our result. 
Result so far: 14827.8
The remainder is 12 after subtracting 168 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 8:
The number 21 fits into 120 5 times, leaving a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 14827.85
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 9:
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: 14827.857
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.

On to step 10:
21 goes into 30 1 times with a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 14827.8571
If we subtract 21 from 30, we 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 11:
When dividing 90 by 21, we get 4 with a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 14827.85714
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.

On to step 12:
If we divide 60 by 21, we get 2 and a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 14827.857142
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.

Let's proceed to step 13:
The number 21 fits into 180 8 times, leaving a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 14827.8571428
Subtract 168 from 180 to 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.

Going ahead to step 14:
21 goes into 120 5 times with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 14827.85714285
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.

In conclusion, the division gives 14827.85714285 with a balance of 1.5e-08.
