18061011 ÷ 830 
The aim is to understand the frequency of 830 in 18061011.

Step 1:
830 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 830

Step 2:
830 can be fit into 18 0 times, resulting in a remainder of 18.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 18, we get 18.
Grab the next digit (0) from the dividend, add it to 18, then carry on: 180 / 830

Advancing to step 3:
830 can be fit into 180 0 times, resulting in a remainder of 180.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 180 and we're left with 180.
Grab the next digit (6) from the dividend, add it to 180, then carry on: 1806 / 830

On to step 4:
If we divide 1806 by 830, we get 2 and a remainder of 146.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 146 after subtracting 1660 from 1806.
Take the next digit (1) from the dividend and append it to 146, then repeat: 1461 / 830

Step 5:
830 can be fit into 1461 1 times, resulting in a remainder of 631.
Use 1 as the next digit of our solution. 
Result so far: 21.0
If we take 830 away from 1461, we end up with 631.
Grab the next digit (0) from the dividend, add it to 631, then carry on: 6310 / 830

Going ahead to step 6:
830 goes into 6310 7 times with a remainder of 500.
The number 7 becomes the next digit in our result. 
Result so far: 217.0
Deduct 5810 from 6310 and we're left with 500.
Append the next digit (1) from the dividend to 500 and continue with: 5001 / 830

Step 7:
830 goes into 5001 6 times with a remainder of 21.
The number 6 becomes the next digit in our result. 
Result so far: 2176.0
Deduct 4980 from 5001 and we're left with 21.
Include the next digit (1) from the dividend after 21, then repeat: 211 / 830

On to step 8:
If we divide 211 by 830, we get 0 and a remainder of 211.
Record the quotient 0 as the next digit in the result. 
Result so far: 21760.0
If we take 0 away from 211, we end up with 211.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2110, and continue the process.

On to step 9:
2110 divided by 830 is 2 with a remainder of 450.
Write down 2 as next digit of the result. 
Result so far: 21760.2
If we subtract 1660 from 2110, we get 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Moving on to step 10:
830 goes into 4500 5 times with a remainder of 350.
The next digit of our result is 5. 
Result so far: 21760.25
Subtracting 4150 from 4500 leaves us with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Going ahead to step 11:
When dividing 3500 by 830, we get 4 with a remainder of 180.
Write down 4 as next digit of the result. 
Result so far: 21760.254
The remainder is 180 after subtracting 3320 from 3500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Let's proceed to step 12:
830 can be fit into 1800 2 times, resulting in a remainder of 140.
Record the quotient 2 as the next digit in the result. 
Result so far: 21760.2542
Subtracting 1660 from 1800 leaves us with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Let's proceed to step 13:
1400 divided by 830 is 1 with a remainder of 570.
Write down 1 as next digit of the result. 
Result so far: 21760.25421
Subtract 830 from 1400 to get 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 14:
830 goes into 5700 6 times with a remainder of 720.
Put 6 as the next digit of the answer. 
Result so far: 21760.254216
If we take 4980 away from 5700, we end up with 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Moving on to step 15:
The number 830 fits into 7200 8 times, leaving a remainder of 560.
Use 8 as the next digit of our solution. 
Result so far: 21760.2542168
The remainder is 560 after subtracting 6640 from 7200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Let's proceed to step 16:
The number 830 fits into 5600 6 times, leaving a remainder of 620.
Put 6 as the next digit of the answer. 
Result so far: 21760.25421686
The remainder is 620 after subtracting 4980 from 5600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

The final result is 21760.25421686 with a remainder of 6.2e-07.
