17034424 divided by 21 
Our goal is to divide 17034424 by 21.

Let's proceed to step 1:
When dividing 1 by 21, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 21

Going ahead to step 2:
The number 21 fits into 17 0 times, leaving a remainder of 17.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 17 and we're left with 17.
Append the next digit (0) from the dividend to 17 and continue with: 170 / 21

Step 3:
21 can be fit into 170 8 times, resulting in a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 8.0
Deduct 168 from 170 and we're left with 2.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 21

Advancing to step 4:
When dividing 23 by 21, we get 1 with a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 81.0
The remainder is 2 after subtracting 21 from 23.
Bring next digit (4) of the dividend behind the 2 and repeat the process: 24 / 21

Advancing to step 5:
When dividing 24 by 21, we get 1 with a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 811.0
Subtracting 21 from 24 leaves us with 3.
Take the next digit (4) from the dividend and append it to 3, then repeat: 34 / 21

Let's proceed to step 6:
21 can be fit into 34 1 times, resulting in a remainder of 13.
Put 1 as the next digit of the answer. 
Result so far: 8111.0
If we take 21 away from 34, we end up with 13.
Append the next digit (2) from the dividend to 13 and continue with: 132 / 21

Step 7:
When dividing 132 by 21, we get 6 with a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 81116.0
The remainder is 6 after subtracting 126 from 132.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 21

Moving on to step 8:
When dividing 64 by 21, we get 3 with a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 811163.0
Deduct 63 from 64 and we're left 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.

Advancing to step 9:
21 can be fit into 10 0 times, resulting in a remainder of 10.
The next digit of our result is 0. 
Result so far: 811163.0
Deduct 0 from 10 and we're left 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.

Advancing to step 10:
The number 21 fits into 100 4 times, leaving a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 811163.04
Deduct 84 from 100 and we're left 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.

On to step 11:
160 divided by 21 is 7 with a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 811163.047
If we take 147 away from 160, we end up 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.

Let's proceed to step 12:
The number 21 fits into 130 6 times, leaving a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 811163.0476
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.

Going ahead to step 13:
21 can be fit into 40 1 times, resulting in a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 811163.04761
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 14:
190 divided by 21 is 9 with a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 811163.047619
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.

Step 15:
21 can be fit into 10 0 times, resulting in a remainder of 10.
The next digit of our result is 0. 
Result so far: 811163.047619
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.

On to step 16:
When dividing 100 by 21, we get 4 with a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 811163.04761904
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.

In conclusion, the division gives 811163.04761904 with a balance of 1.6e-08.
