We look at the division of 311611 by 21 
Our goal is to divide 311611 by 21.

On to step 1:
When dividing 3 by 21, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 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.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 21 away from 31, we end up with 10.
Bring next digit (1) of the dividend behind the 10 and repeat the process: 101 / 21

Moving on to step 3:
21 can be fit into 101 4 times, resulting in a remainder of 17.
Use 4 as the next digit of our solution. 
Result so far: 14.0
Deduct 84 from 101 and we're left with 17.
Fetch the next digit (6) from the dividend, attach it to 17 and continue: 176 / 21

Advancing to step 4:
21 goes into 176 8 times with a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 148.0
Subtract 168 from 176 to get 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 21

Moving on to step 5:
21 goes into 81 3 times with a remainder of 18.
Write down 3 as next digit of the result. 
Result so far: 1483.0
Deduct 63 from 81 and we're left with 18.
Take the next digit (1) from the dividend and append it to 18, then repeat: 181 / 21

Let's proceed to step 6:
When dividing 181 by 21, we get 8 with a remainder of 13.
The number 8 becomes the next digit in our result. 
Result so far: 14838.0
If we subtract 168 from 181, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 7:
130 divided by 21 is 6 with a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 14838.6
The remainder is 4 after subtracting 126 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 8:
21 goes into 40 1 times with a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 14838.61
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 9:
When dividing 190 by 21, we get 9 with a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 14838.619
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.

Moving on to step 10:
The number 21 fits into 10 0 times, leaving a remainder of 10.
The next digit of our result is 0. 
Result so far: 14838.619
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.

Let's proceed to step 11:
21 goes into 100 4 times with a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 14838.61904
If we subtract 84 from 100, we get 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 12:
160 divided by 21 is 7 with a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 14838.619047
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.

Step 13:
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: 14838.6190476
The remainder is 4 after subtracting 126 from 130.
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 14:
The number 21 fits into 40 1 times, leaving a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 14838.61904761
If we subtract 21 from 40, we 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.

The final outcome is 14838.61904761, with a leftover of 1.9e-08.
