72166770 ÷ 830 
The aim is to understand the frequency of 830 in 72166770.

Moving on to step 1:
The number 830 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 830

Moving on to step 2:
830 goes into 72 0 times with a remainder of 72.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 72, we get 72.
Append the next digit (1) from the dividend to 72 and continue with: 721 / 830

Step 3:
721 divided by 830 is 0 with a remainder of 721.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 721 and we're left with 721.
Grab the next digit (6) from the dividend, add it to 721, then carry on: 7216 / 830

On to step 4:
If we divide 7216 by 830, we get 8 and a remainder of 576.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we subtract 6640 from 7216, we get 576.
Bring next digit (6) of the dividend behind the 576 and repeat the process: 5766 / 830

Step 5:
830 can be fit into 5766 6 times, resulting in a remainder of 786.
Put 6 as the next digit of the answer. 
Result so far: 86.0
The remainder is 786 after subtracting 4980 from 5766.
Grab the next digit (7) from the dividend, add it to 786, then carry on: 7867 / 830

Step 6:
When dividing 7867 by 830, we get 9 with a remainder of 397.
Record the quotient 9 as the next digit in the result. 
Result so far: 869.0
If we subtract 7470 from 7867, we get 397.
Append the next digit (7) from the dividend to 397 and continue with: 3977 / 830

Advancing to step 7:
When dividing 3977 by 830, we get 4 with a remainder of 657.
Use 4 as the next digit of our solution. 
Result so far: 8694.0
The remainder is 657 after subtracting 3320 from 3977.
Grab the next digit (0) from the dividend, add it to 657, then carry on: 6570 / 830

On to step 8:
The number 830 fits into 6570 7 times, leaving a remainder of 760.
Use 7 as the next digit of our solution. 
Result so far: 86947.0
Subtracting 5810 from 6570 leaves us with 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

Step 9:
830 goes into 7600 9 times with a remainder of 130.
Use 9 as the next digit of our solution. 
Result so far: 86947.9
Deduct 7470 from 7600 and we're left with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Moving on to step 10:
When dividing 1300 by 830, we get 1 with a remainder of 470.
Record the quotient 1 as the next digit in the result. 
Result so far: 86947.91
If we take 830 away from 1300, we end up with 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Step 11:
830 can be fit into 4700 5 times, resulting in a remainder of 550.
Put 5 as the next digit of the answer. 
Result so far: 86947.915
Deduct 4150 from 4700 and we're left with 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Advancing to step 12:
830 can be fit into 5500 6 times, resulting in a remainder of 520.
The next digit of our result is 6. 
Result so far: 86947.9156
Subtract 4980 from 5500 to get 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Moving on to step 13:
When dividing 5200 by 830, we get 6 with a remainder of 220.
Put 6 as the next digit of the answer. 
Result so far: 86947.91566
If we subtract 4980 from 5200, we get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Our division results in 86947.91566 with a remaining 0.00022.
