We divide 21417595 by 830
Our goal is to divide 21417595 by 830.

Going ahead to step 1:
The number 830 fits into 2 0 times, leaving 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.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 830

Step 2:
When dividing 21 by 830, we get 0 with a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Grab the next digit (4) from the dividend, add it to 21, then carry on: 214 / 830

Step 3:
If we divide 214 by 830, we get 0 and a remainder of 214.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 214, we get 214.
Grab the next digit (1) from the dividend, add it to 214, then carry on: 2141 / 830

Step 4:
830 can be fit into 2141 2 times, resulting in a remainder of 481.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 1660 from 2141 leaves us with 481.
Bring next digit (7) of the dividend behind the 481 and repeat the process: 4817 / 830

Step 5:
4817 divided by 830 is 5 with a remainder of 667.
Write down 5 as next digit of the result. 
Result so far: 25.0
The remainder is 667 after subtracting 4150 from 4817.
Include the next digit (5) from the dividend after 667, then repeat: 6675 / 830

Advancing to step 6:
The number 830 fits into 6675 8 times, leaving a remainder of 35.
Use 8 as the next digit of our solution. 
Result so far: 258.0
If we take 6640 away from 6675, we end up with 35.
Include the next digit (9) from the dividend after 35, then repeat: 359 / 830

Let's proceed to step 7:
359 divided by 830 is 0 with a remainder of 359.
Put 0 as the next digit of the answer. 
Result so far: 2580.0
If we subtract 0 from 359, we get 359.
Take the next digit (5) from the dividend and append it to 359, then repeat: 3595 / 830

Moving on to step 8:
If we divide 3595 by 830, we get 4 and a remainder of 275.
Record the quotient 4 as the next digit in the result. 
Result so far: 25804.0
If we take 3320 away from 3595, we end up with 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

On to step 9:
When dividing 2750 by 830, we get 3 with a remainder of 260.
The number 3 becomes the next digit in our result. 
Result so far: 25804.3
If we take 2490 away from 2750, we end up with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Advancing to step 10:
If we divide 2600 by 830, we get 3 and a remainder of 110.
Use 3 as the next digit of our solution. 
Result so far: 25804.33
Subtract 2490 from 2600 to get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

After the division, we end up with 25804.33 and a remainder of 0.11.
