68087078 ÷ 830 
The aim is to understand the frequency of 830 in 68087078.

Let's proceed to step 1:
6 divided by 830 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 830

Going ahead to step 2:
When dividing 68 by 830, we get 0 with a remainder of 68.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 68, we get 68.
Include the next digit (0) from the dividend after 68, then repeat: 680 / 830

Moving on to step 3:
If we divide 680 by 830, we get 0 and a remainder of 680.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 680, we get 680.
Include the next digit (8) from the dividend after 680, then repeat: 6808 / 830

Let's proceed to step 4:
If we divide 6808 by 830, we get 8 and a remainder of 168.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we subtract 6640 from 6808, we get 168.
Bring next digit (7) of the dividend behind the 168 and repeat the process: 1687 / 830

Going ahead to step 5:
1687 divided by 830 is 2 with a remainder of 27.
Write down 2 as next digit of the result. 
Result so far: 82.0
If we subtract 1660 from 1687, we get 27.
Grab the next digit (0) from the dividend, add it to 27, then carry on: 270 / 830

Step 6:
If we divide 270 by 830, we get 0 and a remainder of 270.
The number 0 becomes the next digit in our result. 
Result so far: 820.0
Subtracting 0 from 270 leaves us with 270.
Include the next digit (7) from the dividend after 270, then repeat: 2707 / 830

Step 7:
If we divide 2707 by 830, we get 3 and a remainder of 217.
The number 3 becomes the next digit in our result. 
Result so far: 8203.0
If we take 2490 away from 2707, we end up with 217.
Append the next digit (8) from the dividend to 217 and continue with: 2178 / 830

On to step 8:
2178 divided by 830 is 2 with a remainder of 518.
Write down 2 as next digit of the result. 
Result so far: 82032.0
Subtract 1660 from 2178 to get 518.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5180, and continue the process.

Going ahead to step 9:
830 can be fit into 5180 6 times, resulting in a remainder of 200.
Record the quotient 6 as the next digit in the result. 
Result so far: 82032.6
The remainder is 200 after subtracting 4980 from 5180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Moving on to step 10:
830 can be fit into 2000 2 times, resulting in a remainder of 340.
Write down 2 as next digit of the result. 
Result so far: 82032.62
Deduct 1660 from 2000 and we're left with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Advancing to step 11:
830 goes into 3400 4 times with a remainder of 80.
Use 4 as the next digit of our solution. 
Result so far: 82032.624
If we subtract 3320 from 3400, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 12:
800 divided by 830 is 0 with a remainder of 800.
Put 0 as the next digit of the answer. 
Result so far: 82032.624
The remainder is 800 after subtracting 0 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

Moving on to step 13:
830 goes into 8000 9 times with a remainder of 530.
The next digit of our result is 9. 
Result so far: 82032.62409
The remainder is 530 after subtracting 7470 from 8000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

Advancing to step 14:
830 can be fit into 5300 6 times, resulting in a remainder of 320.
Use 6 as the next digit of our solution. 
Result so far: 82032.624096
Subtract 4980 from 5300 to get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Step 15:
The number 830 fits into 3200 3 times, leaving a remainder of 710.
Use 3 as the next digit of our solution. 
Result so far: 82032.6240963
The remainder is 710 after subtracting 2490 from 3200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7100, and continue the process.

Moving on to step 16:
7100 divided by 830 is 8 with a remainder of 460.
Use 8 as the next digit of our solution. 
Result so far: 82032.62409638
Subtracting 6640 from 7100 leaves us with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

The final outcome is 82032.62409638, with a leftover of 4.6e-07.
