We're dividing 89906403 by 829 
The aim is to understand the frequency of 829 in 89906403.

Moving on to step 1:
8 divided by 829 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (9) from the dividend, add it to 8, then carry on: 89 / 829

Moving on to step 2:
When dividing 89 by 829, we get 0 with a remainder of 89.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 89, we get 89.
Fetch the next digit (9) from the dividend, attach it to 89 and continue: 899 / 829

Advancing to step 3:
If we divide 899 by 829, we get 1 and a remainder of 70.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 829 from 899 leaves us with 70.
Fetch the next digit (0) from the dividend, attach it to 70 and continue: 700 / 829

On to step 4:
829 goes into 700 0 times with a remainder of 700.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
If we subtract 0 from 700, we get 700.
Include the next digit (6) from the dividend after 700, then repeat: 7006 / 829

Advancing to step 5:
The number 829 fits into 7006 8 times, leaving a remainder of 374.
Use 8 as the next digit of our solution. 
Result so far: 108.0
Subtracting 6632 from 7006 leaves us with 374.
Take the next digit (4) from the dividend and append it to 374, then repeat: 3744 / 829

On to step 6:
The number 829 fits into 3744 4 times, leaving a remainder of 428.
The number 4 becomes the next digit in our result. 
Result so far: 1084.0
Subtract 3316 from 3744 to get 428.
Grab the next digit (0) from the dividend, add it to 428, then carry on: 4280 / 829

Step 7:
The number 829 fits into 4280 5 times, leaving a remainder of 135.
Use 5 as the next digit of our solution. 
Result so far: 10845.0
The remainder is 135 after subtracting 4145 from 4280.
Fetch the next digit (3) from the dividend, attach it to 135 and continue: 1353 / 829

Step 8:
If we divide 1353 by 829, we get 1 and a remainder of 524.
Record the quotient 1 as the next digit in the result. 
Result so far: 108451.0
Deduct 829 from 1353 and we're left with 524.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5240, and continue the process.

On to step 9:
If we divide 5240 by 829, we get 6 and a remainder of 266.
Use 6 as the next digit of our solution. 
Result so far: 108451.6
The remainder is 266 after subtracting 4974 from 5240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

Step 10:
When dividing 2660 by 829, we get 3 with a remainder of 173.
The next digit of our result is 3. 
Result so far: 108451.63
Subtract 2487 from 2660 to get 173.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1730, and continue the process.

Moving on to step 11:
829 can be fit into 1730 2 times, resulting in a remainder of 72.
Write down 2 as next digit of the result. 
Result so far: 108451.632
If we subtract 1658 from 1730, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 12:
829 goes into 720 0 times with a remainder of 720.
The next digit of our result is 0. 
Result so far: 108451.632
Subtract 0 from 720 to get 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 13:
7200 divided by 829 is 8 with a remainder of 568.
Record the quotient 8 as the next digit in the result. 
Result so far: 108451.63208
The remainder is 568 after subtracting 6632 from 7200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5680, and continue the process.

Step 14:
When dividing 5680 by 829, we get 6 with a remainder of 706.
The next digit of our result is 6. 
Result so far: 108451.632086
Subtract 4974 from 5680 to get 706.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7060, and continue the process.

Let's proceed to step 15:
If we divide 7060 by 829, we get 8 and a remainder of 428.
Record the quotient 8 as the next digit in the result. 
Result so far: 108451.6320868
Deduct 6632 from 7060 and we're left with 428.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

Moving on to step 16:
4280 divided by 829 is 5 with a remainder of 135.
Put 5 as the next digit of the answer. 
Result so far: 108451.63208685
If we subtract 4145 from 4280, we get 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

The final result is 108451.63208685 with a remainder of 1.35e-07.
