Bring next digit (1) of the dividend behind the 14 and repeat the process: 141 / 21

On to step 4:
21 goes into 141 6 times with a remainder of 15.
Write down 6 as next digit of the result. 
Result so far: 276.0
The remainder is 15 after subtracting 126 from 141.
Include the next digit (4) from the dividend after 15, then repeat: 154 / 21

Advancing to step 5:
The number 21 fits into 154 7 times, leaving a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 2767.0
Subtracting 147 from 154 leaves us with 7.
Fetch the next digit (6) from the dividend, attach it to 7 and continue: 76 / 21

Advancing to step 6:
21 goes into 76 3 times with a remainder of 13.
The number 3 becomes the next digit in our result. 
Result so far: 27673.0
The remainder is 13 after subtracting 63 from 76.
Take the next digit (2) from the dividend and append it to 13, then repeat: 132 / 21

Going ahead to step 7:
The number 21 fits into 132 6 times, leaving a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 276736.0
Subtract 126 from 132 to get 6.
Bring next digit (7) of the dividend behind the 6 and repeat the process: 67 / 21

Let's proceed to step 8:
When dividing 67 by 21, we get 3 with a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 2767363.0
The remainder is 4 after subtracting 63 from 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 9:
When dividing 40 by 21, we get 1 with a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 2767363.1
The remainder is 19 after subtracting 21 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 10:
21 can be fit into 190 9 times, resulting in a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 2767363.19
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.

Advancing to step 11:
When dividing 10 by 21, we get 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 2767363.19
If we subtract 0 from 10, we get 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 12:
When dividing 100 by 21, we get 4 with a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 2767363.1904
The remainder is 16 after subtracting 84 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 13:
160 divided by 21 is 7 with a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 2767363.19047
Deduct 147 from 160 and we're left 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.

Going ahead to step 14:
The number 21 fits into 130 6 times, leaving a remainder of 4.
The next digit of our result is 6. 
Result so far: 2767363.190476
Subtract 126 from 130 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 15:
21 goes into 40 1 times with a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 2767363.1904761
Subtracting 21 from 40 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 16:
The number 21 fits into 190 9 times, leaving a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 2767363.19047619
Subtracting 189 from 190 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The final result is 2767363.19047619 with a remainder of 1e-09.
