Let's divide 71629589 by 830
The aim is to understand the frequency of 830 in 71629589.

Moving on to step 1:
7 divided by 830 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 830

On to step 2:
830 can be fit into 71 0 times, resulting in a remainder of 71.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 71 leaves us with 71.
Take the next digit (6) from the dividend and append it to 71, then repeat: 716 / 830

On to step 3:
If we divide 716 by 830, we get 0 and a remainder of 716.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 716 leaves us with 716.
Take the next digit (2) from the dividend and append it to 716, then repeat: 7162 / 830

Step 4:
830 goes into 7162 8 times with a remainder of 522.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we subtract 6640 from 7162, we get 522.
Take the next digit (9) from the dividend and append it to 522, then repeat: 5229 / 830

On to step 5:
830 can be fit into 5229 6 times, resulting in a remainder of 249.
The next digit of our result is 6. 
Result so far: 86.0
Subtracting 4980 from 5229 leaves us with 249.
Bring next digit (5) of the dividend behind the 249 and repeat the process: 2495 / 830

Let's proceed to step 6:
830 goes into 2495 3 times with a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 863.0
Deduct 2490 from 2495 and we're left with 5.
Fetch the next digit (8) from the dividend, attach it to 5 and continue: 58 / 830

Let's proceed to step 7:
830 can be fit into 58 0 times, resulting in a remainder of 58.
The number 0 becomes the next digit in our result. 
Result so far: 8630.0
Deduct 0 from 58 and we're left with 58.
Take the next digit (9) from the dividend and append it to 58, then repeat: 589 / 830

On to step 8:
If we divide 589 by 830, we get 0 and a remainder of 589.
Record the quotient 0 as the next digit in the result. 
Result so far: 86300.0
If we take 0 away from 589, we end up with 589.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5890, and continue the process.

Moving on to step 9:
When dividing 5890 by 830, we get 7 with a remainder of 80.
The next digit of our result is 7. 
Result so far: 86300.7
Subtracting 5810 from 5890 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 10:
800 divided by 830 is 0 with a remainder of 800.
The number 0 becomes the next digit in our result. 
Result so far: 86300.7
Subtracting 0 from 800 leaves us with 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

On to step 11:
8000 divided by 830 is 9 with a remainder of 530.
Record the quotient 9 as the next digit in the result. 
Result so far: 86300.709
Deduct 7470 from 8000 and we're left with 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

Step 12:
5300 divided by 830 is 6 with a remainder of 320.
Use 6 as the next digit of our solution. 
Result so far: 86300.7096
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.

Going ahead to step 13:
When dividing 3200 by 830, we get 3 with a remainder of 710.
Write down 3 as next digit of the result. 
Result so far: 86300.70963
Deduct 2490 from 3200 and we're left with 710.
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 14:
When dividing 7100 by 830, we get 8 with a remainder of 460.
Use 8 as the next digit of our solution. 
Result so far: 86300.709638
The remainder is 460 after subtracting 6640 from 7100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Moving on to step 15:
830 can be fit into 4600 5 times, resulting in a remainder of 450.
Write down 5 as next digit of the result. 
Result so far: 86300.7096385
Subtracting 4150 from 4600 leaves us with 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 16:
The number 830 fits into 4500 5 times, leaving a remainder of 350.
The number 5 becomes the next digit in our result. 
Result so far: 86300.70963855
Subtract 4150 from 4500 to get 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

The final outcome is 86300.70963855, with a leftover of 3.5e-07.
