Let's divide 64489480 by 830
Let's see how many times 830 fits into 64489480.

On to step 1:
6 divided by 830 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 830

Going ahead to step 2:
The number 830 fits into 64 0 times, leaving a remainder of 64.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 64 and we're left with 64.
Grab the next digit (4) from the dividend, add it to 64, then carry on: 644 / 830

Step 3:
830 goes into 644 0 times with a remainder of 644.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 644 to get 644.
Take the next digit (8) from the dividend and append it to 644, then repeat: 6448 / 830

Moving on to step 4:
The number 830 fits into 6448 7 times, leaving a remainder of 638.
The next digit of our result is 7. 
Result so far: 7.0
The remainder is 638 after subtracting 5810 from 6448.
Bring next digit (9) of the dividend behind the 638 and repeat the process: 6389 / 830

Let's proceed to step 5:
When dividing 6389 by 830, we get 7 with a remainder of 579.
Use 7 as the next digit of our solution. 
Result so far: 77.0
Subtract 5810 from 6389 to get 579.
Fetch the next digit (4) from the dividend, attach it to 579 and continue: 5794 / 830

Moving on to step 6:
When dividing 5794 by 830, we get 6 with a remainder of 814.
Record the quotient 6 as the next digit in the result. 
Result so far: 776.0
Deduct 4980 from 5794 and we're left with 814.
Bring next digit (8) of the dividend behind the 814 and repeat the process: 8148 / 830

Advancing to step 7:
When dividing 8148 by 830, we get 9 with a remainder of 678.
Use 9 as the next digit of our solution. 
Result so far: 7769.0
Subtracting 7470 from 8148 leaves us with 678.
Append the next digit (0) from the dividend to 678 and continue with: 6780 / 830

Advancing to step 8:
If we divide 6780 by 830, we get 8 and a remainder of 140.
Put 8 as the next digit of the answer. 
Result so far: 77698.0
Subtract 6640 from 6780 to get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

On to step 9:
If we divide 1400 by 830, we get 1 and a remainder of 570.
The number 1 becomes the next digit in our result. 
Result so far: 77698.1
If we take 830 away from 1400, we end up with 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5700, and continue the process.

Moving on to step 10:
If we divide 5700 by 830, we get 6 and a remainder of 720.
The number 6 becomes the next digit in our result. 
Result so far: 77698.16
If we subtract 4980 from 5700, we get 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Let's proceed to step 11:
7200 divided by 830 is 8 with a remainder of 560.
Record the quotient 8 as the next digit in the result. 
Result so far: 77698.168
If we take 6640 away from 7200, we end up with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Advancing to step 12:
If we divide 5600 by 830, we get 6 and a remainder of 620.
The number 6 becomes the next digit in our result. 
Result so far: 77698.1686
If we take 4980 away from 5600, we end up with 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Going ahead to step 13:
830 goes into 6200 7 times with a remainder of 390.
Use 7 as the next digit of our solution. 
Result so far: 77698.16867
Subtract 5810 from 6200 to get 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Step 14:
The number 830 fits into 3900 4 times, leaving a remainder of 580.
The next digit of our result is 4. 
Result so far: 77698.168674
The remainder is 580 after subtracting 3320 from 3900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Advancing to step 15:
830 can be fit into 5800 6 times, resulting in a remainder of 820.
Write down 6 as next digit of the result. 
Result so far: 77698.1686746
If we subtract 4980 from 5800, we get 820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8200, and continue the process.

Let's proceed to step 16:
The number 830 fits into 8200 9 times, leaving a remainder of 730.
The number 9 becomes the next digit in our result. 
Result so far: 77698.16867469
Deduct 7470 from 8200 and we're left with 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7300, and continue the process.

In conclusion, the division gives 77698.16867469 with a balance of 7.3e-07.
