Let's divide 29127271 by 21
We're looking to find how many times 21 goes into 29127271.

Moving on to step 1:
When dividing 2 by 21, we get 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (9) from the dividend to 2 and continue with: 29 / 21

Let's proceed to step 2:
If we divide 29 by 21, we get 1 and a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 21 from 29 and we're left with 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 21

Advancing to step 3:
81 divided by 21 is 3 with a remainder of 18.
The next digit of our result is 3. 
Result so far: 13.0
The remainder is 18 after subtracting 63 from 81.
Grab the next digit (2) from the dividend, add it to 18, then carry on: 182 / 21

On to step 4:
21 goes into 182 8 times with a remainder of 14.
Use 8 as the next digit of our solution. 
Result so far: 138.0
Subtracting 168 from 182 leaves us with 14.
Include the next digit (7) from the dividend after 14, then repeat: 147 / 21

Let's proceed to step 5:
When dividing 147 by 21, we get 7 with a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 1387.0
The remainder is 0 after subtracting 147 from 147.
Append the next digit (2) from the dividend to 0 and continue with: 2 / 21

Going ahead to step 6:
21 goes into 2 0 times with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 13870.0
If we take 0 away from 2, we end up with 2.
Grab the next digit (7) from the dividend, add it to 2, then carry on: 27 / 21

Moving on to step 7:
If we divide 27 by 21, we get 1 and a remainder of 6.
Use 1 as the next digit of our solution. 
Result so far: 138701.0
The remainder is 6 after subtracting 21 from 27.
Bring next digit (1) of the dividend behind the 6 and repeat the process: 61 / 21

On to step 8:
When dividing 61 by 21, we get 2 with a remainder of 19.
Use 2 as the next digit of our solution. 
Result so far: 1387012.0
Subtracting 42 from 61 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 9:
190 divided by 21 is 9 with a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 1387012.9
If we subtract 189 from 190, we 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.

On to step 10:
21 goes into 10 0 times with a remainder of 10.
The next digit of our result is 0. 
Result so far: 1387012.9
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.

Step 11:
100 divided by 21 is 4 with a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 1387012.904
If we take 84 away from 100, we end up with 16.
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 12:
160 divided by 21 is 7 with a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 1387012.9047
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.

Moving on to 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: 1387012.90476
Subtracting 126 from 130 leaves us with 4.
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.
Use 1 as the next digit of our solution. 
Result so far: 1387012.904761
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.

On to step 15:
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: 1387012.9047619
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.

Let's proceed to step 16:
10 divided by 21 is 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 1387012.9047619
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.

The final result is 1387012.9047619 with a remainder of 1e-08.
