Let's divide 78252712 by 826
The aim is to understand the frequency of 826 in 78252712.

On to step 1:
The number 826 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 826

Moving on to step 2:
When dividing 78 by 826, we get 0 with a remainder of 78.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 78 leaves us with 78.
Fetch the next digit (2) from the dividend, attach it to 78 and continue: 782 / 826

Going ahead to step 3:
826 can be fit into 782 0 times, resulting in a remainder of 782.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 782, we end up with 782.
Fetch the next digit (5) from the dividend, attach it to 782 and continue: 7825 / 826

On to step 4:
When dividing 7825 by 826, we get 9 with a remainder of 391.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we take 7434 away from 7825, we end up with 391.
Include the next digit (2) from the dividend after 391, then repeat: 3912 / 826

On to step 5:
If we divide 3912 by 826, we get 4 and a remainder of 608.
Write down 4 as next digit of the result. 
Result so far: 94.0
Subtracting 3304 from 3912 leaves us with 608.
Bring next digit (7) of the dividend behind the 608 and repeat the process: 6087 / 826

On to step 6:
826 can be fit into 6087 7 times, resulting in a remainder of 305.
Write down 7 as next digit of the result. 
Result so far: 947.0
If we take 5782 away from 6087, we end up with 305.
Include the next digit (1) from the dividend after 305, then repeat: 3051 / 826

Going ahead to step 7:
When dividing 3051 by 826, we get 3 with a remainder of 573.
The next digit of our result is 3. 
Result so far: 9473.0
If we take 2478 away from 3051, we end up with 573.
Append the next digit (2) from the dividend to 573 and continue with: 5732 / 826

On to step 8:
When dividing 5732 by 826, we get 6 with a remainder of 776.
Put 6 as the next digit of the answer. 
Result so far: 94736.0
If we subtract 4956 from 5732, we get 776.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7760, and continue the process.

Let's proceed to step 9:
The number 826 fits into 7760 9 times, leaving a remainder of 326.
Use 9 as the next digit of our solution. 
Result so far: 94736.9
If we take 7434 away from 7760, we end up with 326.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

Step 10:
826 goes into 3260 3 times with a remainder of 782.
The next digit of our result is 3. 
Result so far: 94736.93
The remainder is 782 after subtracting 2478 from 3260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7820, and continue the process.

Step 11:
When dividing 7820 by 826, we get 9 with a remainder of 386.
Use 9 as the next digit of our solution. 
Result so far: 94736.939
If we take 7434 away from 7820, we end up with 386.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

Advancing to step 12:
3860 divided by 826 is 4 with a remainder of 556.
Use 4 as the next digit of our solution. 
Result so far: 94736.9394
Deduct 3304 from 3860 and we're left with 556.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5560, and continue the process.

Going ahead to step 13:
When dividing 5560 by 826, we get 6 with a remainder of 604.
Record the quotient 6 as the next digit in the result. 
Result so far: 94736.93946
Subtracting 4956 from 5560 leaves us with 604.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6040, and continue the process.

Advancing to step 14:
When dividing 6040 by 826, we get 7 with a remainder of 258.
Use 7 as the next digit of our solution. 
Result so far: 94736.939467
Subtract 5782 from 6040 to get 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Going ahead to step 15:
2580 divided by 826 is 3 with a remainder of 102.
Put 3 as the next digit of the answer. 
Result so far: 94736.9394673
If we subtract 2478 from 2580, we get 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Let's proceed to step 16:
The number 826 fits into 1020 1 times, leaving a remainder of 194.
Put 1 as the next digit of the answer. 
Result so far: 94736.93946731
If we subtract 826 from 1020, we get 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

The final outcome is 94736.93946731, with a leftover of 1.94e-07.
