We look at the division of 83636994 by 825 
The aim is to understand the frequency of 825 in 83636994.

Step 1:
8 divided by 825 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (3) of the dividend behind the 8 and repeat the process: 83 / 825

Let's proceed to step 2:
When dividing 83 by 825, we get 0 with a remainder of 83.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 83 and we're left with 83.
Include the next digit (6) from the dividend after 83, then repeat: 836 / 825

Step 3:
836 divided by 825 is 1 with a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 11 after subtracting 825 from 836.
Grab the next digit (3) from the dividend, add it to 11, then carry on: 113 / 825

Advancing to step 4:
825 can be fit into 113 0 times, resulting in a remainder of 113.
Use 0 as the next digit of our solution. 
Result so far: 10.0
The remainder is 113 after subtracting 0 from 113.
Append the next digit (6) from the dividend to 113 and continue with: 1136 / 825

Going ahead to step 5:
The number 825 fits into 1136 1 times, leaving a remainder of 311.
Write down 1 as next digit of the result. 
Result so far: 101.0
If we take 825 away from 1136, we end up with 311.
Take the next digit (9) from the dividend and append it to 311, then repeat: 3119 / 825

Step 6:
The number 825 fits into 3119 3 times, leaving a remainder of 644.
The number 3 becomes the next digit in our result. 
Result so far: 1013.0
Subtracting 2475 from 3119 leaves us with 644.
Take the next digit (9) from the dividend and append it to 644, then repeat: 6449 / 825

Moving on to step 7:
When dividing 6449 by 825, we get 7 with a remainder of 674.
The next digit of our result is 7. 
Result so far: 10137.0
Deduct 5775 from 6449 and we're left with 674.
Take the next digit (4) from the dividend and append it to 674, then repeat: 6744 / 825

Going ahead to step 8:
The number 825 fits into 6744 8 times, leaving a remainder of 144.
Put 8 as the next digit of the answer. 
Result so far: 101378.0
The remainder is 144 after subtracting 6600 from 6744.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

On to step 9:
1440 divided by 825 is 1 with a remainder of 615.
Write down 1 as next digit of the result. 
Result so far: 101378.1
Deduct 825 from 1440 and we're left with 615.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6150, and continue the process.

Advancing to step 10:
6150 divided by 825 is 7 with a remainder of 375.
The next digit of our result is 7. 
Result so far: 101378.17
The remainder is 375 after subtracting 5775 from 6150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Advancing to step 11:
If we divide 3750 by 825, we get 4 and a remainder of 450.
Put 4 as the next digit of the answer. 
Result so far: 101378.174
The remainder is 450 after subtracting 3300 from 3750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Advancing to step 12:
4500 divided by 825 is 5 with a remainder of 375.
Put 5 as the next digit of the answer. 
Result so far: 101378.1745
If we subtract 4125 from 4500, we get 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Going ahead to step 13:
The number 825 fits into 3750 4 times, leaving a remainder of 450.
The number 4 becomes the next digit in our result. 
Result so far: 101378.17454
The remainder is 450 after subtracting 3300 from 3750.
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 14:
If we divide 4500 by 825, we get 5 and a remainder of 375.
Write down 5 as next digit of the result. 
Result so far: 101378.174545
Subtract 4125 from 4500 to get 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Moving on to step 15:
825 can be fit into 3750 4 times, resulting in a remainder of 450.
The next digit of our result is 4. 
Result so far: 101378.1745454
Subtract 3300 from 3750 to 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 16:
4500 divided by 825 is 5 with a remainder of 375.
Put 5 as the next digit of the answer. 
Result so far: 101378.17454545
If we subtract 4125 from 4500, we get 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

In conclusion, the division gives 101378.17454545 with a balance of 3.75e-07.
