Let's divide 21238119 by 829
Our goal is to divide 21238119 by 829.

Moving on to step 1:
2 divided by 829 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 829

Step 2:
The number 829 fits into 21 0 times, leaving a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Take the next digit (2) from the dividend and append it to 21, then repeat: 212 / 829

Moving on to step 3:
When dividing 212 by 829, we get 0 with a remainder of 212.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 212 to get 212.
Grab the next digit (3) from the dividend, add it to 212, then carry on: 2123 / 829

Advancing to step 4:
When dividing 2123 by 829, we get 2 with a remainder of 465.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 1658 from 2123 leaves us with 465.
Bring next digit (8) of the dividend behind the 465 and repeat the process: 4658 / 829

Moving on to step 5:
829 goes into 4658 5 times with a remainder of 513.
Use 5 as the next digit of our solution. 
Result so far: 25.0
Deduct 4145 from 4658 and we're left with 513.
Include the next digit (1) from the dividend after 513, then repeat: 5131 / 829

Moving on to step 6:
5131 divided by 829 is 6 with a remainder of 157.
Use 6 as the next digit of our solution. 
Result so far: 256.0
Subtracting 4974 from 5131 leaves us with 157.
Include the next digit (1) from the dividend after 157, then repeat: 1571 / 829

Advancing to step 7:
The number 829 fits into 1571 1 times, leaving a remainder of 742.
Record the quotient 1 as the next digit in the result. 
Result so far: 2561.0
If we subtract 829 from 1571, we get 742.
Fetch the next digit (9) from the dividend, attach it to 742 and continue: 7429 / 829

Advancing to step 8:
829 can be fit into 7429 8 times, resulting in a remainder of 797.
The next digit of our result is 8. 
Result so far: 25618.0
The remainder is 797 after subtracting 6632 from 7429.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7970, and continue the process.

Advancing to step 9:
When dividing 7970 by 829, we get 9 with a remainder of 509.
Use 9 as the next digit of our solution. 
Result so far: 25618.9
The remainder is 509 after subtracting 7461 from 7970.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5090, and continue the process.

Let's proceed to step 10:
If we divide 5090 by 829, we get 6 and a remainder of 116.
Write down 6 as next digit of the result. 
Result so far: 25618.96
Deduct 4974 from 5090 and we're left with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Step 11:
829 goes into 1160 1 times with a remainder of 331.
Write down 1 as next digit of the result. 
Result so far: 25618.961
The remainder is 331 after subtracting 829 from 1160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3310, and continue the process.

Step 12:
If we divide 3310 by 829, we get 3 and a remainder of 823.
Write down 3 as next digit of the result. 
Result so far: 25618.9613
Subtracting 2487 from 3310 leaves us with 823.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8230, and continue the process.

Step 13:
8230 divided by 829 is 9 with a remainder of 769.
Record the quotient 9 as the next digit in the result. 
Result so far: 25618.96139
If we take 7461 away from 8230, we end up with 769.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7690, and continue the process.

Step 14:
829 can be fit into 7690 9 times, resulting in a remainder of 229.
Record the quotient 9 as the next digit in the result. 
Result so far: 25618.961399
If we subtract 7461 from 7690, we get 229.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2290, and continue the process.

The final result is 25618.961399 with a remainder of 2.29e-05.
