69293409 divided by 826 
The aim is to understand the frequency of 826 in 69293409.

Moving on to step 1:
6 divided by 826 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (9) from the dividend after 6, then repeat: 69 / 826

On to step 2:
The number 826 fits into 69 0 times, leaving a remainder of 69.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 69, we get 69.
Fetch the next digit (2) from the dividend, attach it to 69 and continue: 692 / 826

Advancing to step 3:
If we divide 692 by 826, we get 0 and a remainder of 692.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 692 after subtracting 0 from 692.
Grab the next digit (9) from the dividend, add it to 692, then carry on: 6929 / 826

On to step 4:
The number 826 fits into 6929 8 times, leaving a remainder of 321.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we subtract 6608 from 6929, we get 321.
Grab the next digit (3) from the dividend, add it to 321, then carry on: 3213 / 826

Going ahead to step 5:
If we divide 3213 by 826, we get 3 and a remainder of 735.
Use 3 as the next digit of our solution. 
Result so far: 83.0
Subtract 2478 from 3213 to get 735.
Include the next digit (4) from the dividend after 735, then repeat: 7354 / 826

On to step 6:
If we divide 7354 by 826, we get 8 and a remainder of 746.
Record the quotient 8 as the next digit in the result. 
Result so far: 838.0
If we take 6608 away from 7354, we end up with 746.
Append the next digit (0) from the dividend to 746 and continue with: 7460 / 826

On to step 7:
826 can be fit into 7460 9 times, resulting in a remainder of 26.
Record the quotient 9 as the next digit in the result. 
Result so far: 8389.0
Subtracting 7434 from 7460 leaves us with 26.
Take the next digit (9) from the dividend and append it to 26, then repeat: 269 / 826

Moving on to step 8:
826 can be fit into 269 0 times, resulting in a remainder of 269.
Record the quotient 0 as the next digit in the result. 
Result so far: 83890.0
If we subtract 0 from 269, we get 269.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2690, and continue the process.

Going ahead to step 9:
The number 826 fits into 2690 3 times, leaving a remainder of 212.
The number 3 becomes the next digit in our result. 
Result so far: 83890.3
The remainder is 212 after subtracting 2478 from 2690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

On to step 10:
826 can be fit into 2120 2 times, resulting in a remainder of 468.
Use 2 as the next digit of our solution. 
Result so far: 83890.32
If we subtract 1652 from 2120, we get 468.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4680, and continue the process.

Step 11:
The number 826 fits into 4680 5 times, leaving a remainder of 550.
Use 5 as the next digit of our solution. 
Result so far: 83890.325
If we subtract 4130 from 4680, we get 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Going ahead to step 12:
826 goes into 5500 6 times with a remainder of 544.
Put 6 as the next digit of the answer. 
Result so far: 83890.3256
Deduct 4956 from 5500 and we're left with 544.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

On to step 13:
If we divide 5440 by 826, we get 6 and a remainder of 484.
Put 6 as the next digit of the answer. 
Result so far: 83890.32566
The remainder is 484 after subtracting 4956 from 5440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4840, and continue the process.

The final result is 83890.32566 with a remainder of 0.000484.
