We divide 21203037 by 830
Let's see how many times 830 fits into 21203037.

Moving on to step 1:
If we divide 2 by 830, we get 0 and a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 830

Step 2:
The number 830 fits into 21 0 times, leaving a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Include the next digit (2) from the dividend after 21, then repeat: 212 / 830

Going ahead to step 3:
830 can be fit into 212 0 times, resulting in a remainder of 212.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 212 to get 212.
Append the next digit (0) from the dividend to 212 and continue with: 2120 / 830

Going ahead to step 4:
If we divide 2120 by 830, we get 2 and a remainder of 460.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 1660 from 2120 and we're left with 460.
Grab the next digit (3) from the dividend, add it to 460, then carry on: 4603 / 830

Going ahead to step 5:
830 can be fit into 4603 5 times, resulting in a remainder of 453.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
Subtracting 4150 from 4603 leaves us with 453.
Append the next digit (0) from the dividend to 453 and continue with: 4530 / 830

Advancing to step 6:
830 can be fit into 4530 5 times, resulting in a remainder of 380.
Record the quotient 5 as the next digit in the result. 
Result so far: 255.0
Deduct 4150 from 4530 and we're left with 380.
Append the next digit (3) from the dividend to 380 and continue with: 3803 / 830

On to step 7:
When dividing 3803 by 830, we get 4 with a remainder of 483.
Use 4 as the next digit of our solution. 
Result so far: 2554.0
The remainder is 483 after subtracting 3320 from 3803.
Fetch the next digit (7) from the dividend, attach it to 483 and continue: 4837 / 830

Advancing to step 8:
If we divide 4837 by 830, we get 5 and a remainder of 687.
The number 5 becomes the next digit in our result. 
Result so far: 25545.0
If we take 4150 away from 4837, we end up with 687.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6870, and continue the process.

Step 9:
When dividing 6870 by 830, we get 8 with a remainder of 230.
The number 8 becomes the next digit in our result. 
Result so far: 25545.8
If we take 6640 away from 6870, we end up with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Step 10:
If we divide 2300 by 830, we get 2 and a remainder of 640.
The next digit of our result is 2. 
Result so far: 25545.82
If we take 1660 away from 2300, we end up with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Let's proceed to step 11:
6400 divided by 830 is 7 with a remainder of 590.
Use 7 as the next digit of our solution. 
Result so far: 25545.827
Subtracting 5810 from 6400 leaves us with 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

Going ahead to step 12:
The number 830 fits into 5900 7 times, leaving a remainder of 90.
Use 7 as the next digit of our solution. 
Result so far: 25545.8277
If we take 5810 away from 5900, we end up with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

The quotient of the division is 25545.8277, and the remainder is 0.0009.
