We're dividing 69371797 by 825 
The aim is to understand the frequency of 825 in 69371797.

Going ahead to step 1:
6 divided by 825 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (9) from the dividend after 6, then repeat: 69 / 825

Going ahead to step 2:
825 goes into 69 0 times with a remainder of 69.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 69, we get 69.
Append the next digit (3) from the dividend to 69 and continue with: 693 / 825

Going ahead to step 3:
The number 825 fits into 693 0 times, leaving a remainder of 693.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 693, we end up with 693.
Append the next digit (7) from the dividend to 693 and continue with: 6937 / 825

Step 4:
The number 825 fits into 6937 8 times, leaving a remainder of 337.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we subtract 6600 from 6937, we get 337.
Grab the next digit (1) from the dividend, add it to 337, then carry on: 3371 / 825

Moving on to step 5:
When dividing 3371 by 825, we get 4 with a remainder of 71.
The next digit of our result is 4. 
Result so far: 84.0
Subtract 3300 from 3371 to get 71.
Append the next digit (7) from the dividend to 71 and continue with: 717 / 825

Advancing to step 6:
If we divide 717 by 825, we get 0 and a remainder of 717.
Record the quotient 0 as the next digit in the result. 
Result so far: 840.0
If we subtract 0 from 717, we get 717.
Grab the next digit (9) from the dividend, add it to 717, then carry on: 7179 / 825

On to step 7:
When dividing 7179 by 825, we get 8 with a remainder of 579.
Record the quotient 8 as the next digit in the result. 
Result so far: 8408.0
The remainder is 579 after subtracting 6600 from 7179.
Append the next digit (7) from the dividend to 579 and continue with: 5797 / 825

Let's proceed to step 8:
825 goes into 5797 7 times with a remainder of 22.
The next digit of our result is 7. 
Result so far: 84087.0
Deduct 5775 from 5797 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 9:
220 divided by 825 is 0 with a remainder of 220.
Use 0 as the next digit of our solution. 
Result so far: 84087.0
Deduct 0 from 220 and we're left with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Let's proceed to step 10:
When dividing 2200 by 825, we get 2 with a remainder of 550.
Use 2 as the next digit of our solution. 
Result so far: 84087.02
If we take 1650 away from 2200, we end up 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.

Let's proceed to step 11:
825 can be fit into 5500 6 times, resulting in a remainder of 550.
Write down 6 as next digit of the result. 
Result so far: 84087.026
Subtracting 4950 from 5500 leaves us 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.

Moving on to step 12:
If we divide 5500 by 825, we get 6 and a remainder of 550.
The next digit of our result is 6. 
Result so far: 84087.0266
If we take 4950 away from 5500, we end up 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.

The quotient of the division is 84087.0266, and the remainder is 0.0055.
