8425503 divided by 826 
The aim is to understand the frequency of 826 in 8425503.

Let's proceed to step 1:
826 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 826

Let's proceed to step 2:
826 can be fit into 84 0 times, resulting in a remainder of 84.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 84, we get 84.
Include the next digit (2) from the dividend after 84, then repeat: 842 / 826

Going ahead to step 3:
842 divided by 826 is 1 with a remainder of 16.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 826 from 842 to get 16.
Bring next digit (5) of the dividend behind the 16 and repeat the process: 165 / 826

Going ahead to step 4:
If we divide 165 by 826, we get 0 and a remainder of 165.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Deduct 0 from 165 and we're left with 165.
Include the next digit (5) from the dividend after 165, then repeat: 1655 / 826

On to step 5:
The number 826 fits into 1655 2 times, leaving a remainder of 3.
Record the quotient 2 as the next digit in the result. 
Result so far: 102.0
If we take 1652 away from 1655, we end up with 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 826

Step 6:
The number 826 fits into 30 0 times, leaving a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 1020.0
If we take 0 away from 30, we end up with 30.
Take the next digit (3) from the dividend and append it to 30, then repeat: 303 / 826

Step 7:
826 goes into 303 0 times with a remainder of 303.
Write down 0 as next digit of the result. 
Result so far: 10200.0
Subtracting 0 from 303 leaves us with 303.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3030, and continue the process.

Advancing to step 8:
826 goes into 3030 3 times with a remainder of 552.
The number 3 becomes the next digit in our result. 
Result so far: 10200.3
The remainder is 552 after subtracting 2478 from 3030.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5520, and continue the process.

Advancing to step 9:
When dividing 5520 by 826, we get 6 with a remainder of 564.
The number 6 becomes the next digit in our result. 
Result so far: 10200.36
The remainder is 564 after subtracting 4956 from 5520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5640, and continue the process.

Going ahead to step 10:
When dividing 5640 by 826, we get 6 with a remainder of 684.
Put 6 as the next digit of the answer. 
Result so far: 10200.366
Subtract 4956 from 5640 to get 684.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6840, and continue the process.

The quotient of the division is 10200.366, and the remainder is 0.0684.
