We look at the division of 76914029 by 815 
The aim is to understand the frequency of 815 in 76914029.

Moving on to step 1:
815 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (6) from the dividend to 7 and continue with: 76 / 815

Step 2:
815 can be fit into 76 0 times, resulting in a remainder of 76.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 76, we end up with 76.
Append the next digit (9) from the dividend to 76 and continue with: 769 / 815

Step 3:
815 goes into 769 0 times with a remainder of 769.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 769 and we're left with 769.
Take the next digit (1) from the dividend and append it to 769, then repeat: 7691 / 815

Advancing to step 4:
If we divide 7691 by 815, we get 9 and a remainder of 356.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we take 7335 away from 7691, we end up with 356.
Take the next digit (4) from the dividend and append it to 356, then repeat: 3564 / 815

Let's proceed to step 5:
3564 divided by 815 is 4 with a remainder of 304.
Write down 4 as next digit of the result. 
Result so far: 94.0
Subtracting 3260 from 3564 leaves us with 304.
Bring next digit (0) of the dividend behind the 304 and repeat the process: 3040 / 815

Let's proceed to step 6:
815 goes into 3040 3 times with a remainder of 595.
The next digit of our result is 3. 
Result so far: 943.0
The remainder is 595 after subtracting 2445 from 3040.
Append the next digit (2) from the dividend to 595 and continue with: 5952 / 815

Step 7:
The number 815 fits into 5952 7 times, leaving a remainder of 247.
Use 7 as the next digit of our solution. 
Result so far: 9437.0
Deduct 5705 from 5952 and we're left with 247.
Include the next digit (9) from the dividend after 247, then repeat: 2479 / 815

Moving on to step 8:
815 goes into 2479 3 times with a remainder of 34.
Record the quotient 3 as the next digit in the result. 
Result so far: 94373.0
Deduct 2445 from 2479 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 9:
If we divide 340 by 815, we get 0 and a remainder of 340.
The number 0 becomes the next digit in our result. 
Result so far: 94373.0
If we subtract 0 from 340, we get 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 10:
When dividing 3400 by 815, we get 4 with a remainder of 140.
The number 4 becomes the next digit in our result. 
Result so far: 94373.04
If we take 3260 away from 3400, we end up with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Going ahead to step 11:
If we divide 1400 by 815, we get 1 and a remainder of 585.
Write down 1 as next digit of the result. 
Result so far: 94373.041
If we subtract 815 from 1400, we get 585.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5850, and continue the process.

Advancing to step 12:
5850 divided by 815 is 7 with a remainder of 145.
Put 7 as the next digit of the answer. 
Result so far: 94373.0417
The remainder is 145 after subtracting 5705 from 5850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Going ahead to step 13:
When dividing 1450 by 815, we get 1 with a remainder of 635.
The next digit of our result is 1. 
Result so far: 94373.04171
If we subtract 815 from 1450, we get 635.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6350, and continue the process.

Advancing to step 14:
815 goes into 6350 7 times with a remainder of 645.
Record the quotient 7 as the next digit in the result. 
Result so far: 94373.041717
The remainder is 645 after subtracting 5705 from 6350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6450, and continue the process.

Step 15:
6450 divided by 815 is 7 with a remainder of 745.
The number 7 becomes the next digit in our result. 
Result so far: 94373.0417177
The remainder is 745 after subtracting 5705 from 6450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7450, and continue the process.

In conclusion, the division gives 94373.0417177 with a balance of 7.45e-06.
