We're dividing 70225909 by 829 
The aim is to understand the frequency of 829 in 70225909.

Step 1:
829 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Append the next digit (0) from the dividend to 7 and continue with: 70 / 829

Advancing to step 2:
When dividing 70 by 829, we get 0 with a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 70 to get 70.
Bring next digit (2) of the dividend behind the 70 and repeat the process: 702 / 829

Let's proceed to step 3:
The number 829 fits into 702 0 times, leaving a remainder of 702.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 702 leaves us with 702.
Fetch the next digit (2) from the dividend, attach it to 702 and continue: 7022 / 829

On to step 4:
829 goes into 7022 8 times with a remainder of 390.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtract 6632 from 7022 to get 390.
Append the next digit (5) from the dividend to 390 and continue with: 3905 / 829

Step 5:
When dividing 3905 by 829, we get 4 with a remainder of 589.
Put 4 as the next digit of the answer. 
Result so far: 84.0
The remainder is 589 after subtracting 3316 from 3905.
Take the next digit (9) from the dividend and append it to 589, then repeat: 5899 / 829

On to step 6:
829 goes into 5899 7 times with a remainder of 96.
Record the quotient 7 as the next digit in the result. 
Result so far: 847.0
Subtract 5803 from 5899 to get 96.
Take the next digit (0) from the dividend and append it to 96, then repeat: 960 / 829

Let's proceed to step 7:
960 divided by 829 is 1 with a remainder of 131.
Record the quotient 1 as the next digit in the result. 
Result so far: 8471.0
If we take 829 away from 960, we end up with 131.
Take the next digit (9) from the dividend and append it to 131, then repeat: 1319 / 829

Going ahead to step 8:
If we divide 1319 by 829, we get 1 and a remainder of 490.
The next digit of our result is 1. 
Result so far: 84711.0
The remainder is 490 after subtracting 829 from 1319.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Moving on to step 9:
829 can be fit into 4900 5 times, resulting in a remainder of 755.
Write down 5 as next digit of the result. 
Result so far: 84711.5
The remainder is 755 after subtracting 4145 from 4900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7550, and continue the process.

Advancing to step 10:
The number 829 fits into 7550 9 times, leaving a remainder of 89.
Write down 9 as next digit of the result. 
Result so far: 84711.59
The remainder is 89 after subtracting 7461 from 7550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

On to step 11:
890 divided by 829 is 1 with a remainder of 61.
Use 1 as the next digit of our solution. 
Result so far: 84711.591
Subtracting 829 from 890 leaves us with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Moving on to step 12:
If we divide 610 by 829, we get 0 and a remainder of 610.
Record the quotient 0 as the next digit in the result. 
Result so far: 84711.591
If we take 0 away from 610, we end up with 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

Step 13:
The number 829 fits into 6100 7 times, leaving a remainder of 297.
Use 7 as the next digit of our solution. 
Result so far: 84711.59107
Subtract 5803 from 6100 to get 297.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2970, and continue the process.

On to step 14:
The number 829 fits into 2970 3 times, leaving a remainder of 483.
Put 3 as the next digit of the answer. 
Result so far: 84711.591073
Subtract 2487 from 2970 to get 483.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4830, and continue the process.

On to step 15:
If we divide 4830 by 829, we get 5 and a remainder of 685.
Use 5 as the next digit of our solution. 
Result so far: 84711.5910735
If we subtract 4145 from 4830, we get 685.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6850, and continue the process.

Advancing to step 16:
6850 divided by 829 is 8 with a remainder of 218.
Record the quotient 8 as the next digit in the result. 
Result so far: 84711.59107358
Deduct 6632 from 6850 and we're left with 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

After the division, we end up with 84711.59107358 and a remainder of 2.18e-07.
