We're dividing 63346825 by 815 
The aim is to understand the frequency of 815 in 63346825.

Step 1:
6 divided by 815 is 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 815

Let's proceed to step 2:
815 goes into 63 0 times with a remainder of 63.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 63, we get 63.
Bring next digit (3) of the dividend behind the 63 and repeat the process: 633 / 815

Moving on to step 3:
815 can be fit into 633 0 times, resulting in a remainder of 633.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 633 to get 633.
Fetch the next digit (4) from the dividend, attach it to 633 and continue: 6334 / 815

Step 4:
815 goes into 6334 7 times with a remainder of 629.
The next digit of our result is 7. 
Result so far: 7.0
Deduct 5705 from 6334 and we're left with 629.
Fetch the next digit (6) from the dividend, attach it to 629 and continue: 6296 / 815

Going ahead to step 5:
When dividing 6296 by 815, we get 7 with a remainder of 591.
Write down 7 as next digit of the result. 
Result so far: 77.0
If we take 5705 away from 6296, we end up with 591.
Take the next digit (8) from the dividend and append it to 591, then repeat: 5918 / 815

Let's proceed to step 6:
815 can be fit into 5918 7 times, resulting in a remainder of 213.
The number 7 becomes the next digit in our result. 
Result so far: 777.0
Subtract 5705 from 5918 to get 213.
Fetch the next digit (2) from the dividend, attach it to 213 and continue: 2132 / 815

On to step 7:
When dividing 2132 by 815, we get 2 with a remainder of 502.
Record the quotient 2 as the next digit in the result. 
Result so far: 7772.0
Subtracting 1630 from 2132 leaves us with 502.
Take the next digit (5) from the dividend and append it to 502, then repeat: 5025 / 815

Advancing to step 8:
The number 815 fits into 5025 6 times, leaving a remainder of 135.
The number 6 becomes the next digit in our result. 
Result so far: 77726.0
Subtract 4890 from 5025 to get 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Let's proceed to step 9:
815 can be fit into 1350 1 times, resulting in a remainder of 535.
Record the quotient 1 as the next digit in the result. 
Result so far: 77726.1
Deduct 815 from 1350 and we're left with 535.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5350, and continue the process.

On to step 10:
815 can be fit into 5350 6 times, resulting in a remainder of 460.
The number 6 becomes the next digit in our result. 
Result so far: 77726.16
The remainder is 460 after subtracting 4890 from 5350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Moving on to step 11:
When dividing 4600 by 815, we get 5 with a remainder of 525.
Write down 5 as next digit of the result. 
Result so far: 77726.165
If we subtract 4075 from 4600, we get 525.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5250, and continue the process.

Let's proceed to step 12:
The number 815 fits into 5250 6 times, leaving a remainder of 360.
The number 6 becomes the next digit in our result. 
Result so far: 77726.1656
The remainder is 360 after subtracting 4890 from 5250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Step 13:
3600 divided by 815 is 4 with a remainder of 340.
Record the quotient 4 as the next digit in the result. 
Result so far: 77726.16564
Deduct 3260 from 3600 and we're left with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Going ahead to step 14:
When dividing 3400 by 815, we get 4 with a remainder of 140.
The next digit of our result is 4. 
Result so far: 77726.165644
Subtract 3260 from 3400 to get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

The final result is 77726.165644 with a remainder of 1.4e-05.
