We look at the division of 99157450 by 810 
The aim is to understand the frequency of 810 in 99157450.

Advancing to step 1:
810 goes into 9 0 times with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Take the next digit (9) from the dividend and append it to 9, then repeat: 99 / 810

Going ahead to step 2:
99 divided by 810 is 0 with a remainder of 99.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 99 and we're left with 99.
Take the next digit (1) from the dividend and append it to 99, then repeat: 991 / 810

Let's proceed to step 3:
810 goes into 991 1 times with a remainder of 181.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 181 after subtracting 810 from 991.
Bring next digit (5) of the dividend behind the 181 and repeat the process: 1815 / 810

Moving on to step 4:
If we divide 1815 by 810, we get 2 and a remainder of 195.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Deduct 1620 from 1815 and we're left with 195.
Append the next digit (7) from the dividend to 195 and continue with: 1957 / 810

Going ahead to step 5:
810 goes into 1957 2 times with a remainder of 337.
The number 2 becomes the next digit in our result. 
Result so far: 122.0
If we subtract 1620 from 1957, we get 337.
Include the next digit (4) from the dividend after 337, then repeat: 3374 / 810

Let's proceed to step 6:
810 goes into 3374 4 times with a remainder of 134.
Record the quotient 4 as the next digit in the result. 
Result so far: 1224.0
Subtract 3240 from 3374 to get 134.
Bring next digit (5) of the dividend behind the 134 and repeat the process: 1345 / 810

Step 7:
The number 810 fits into 1345 1 times, leaving a remainder of 535.
The number 1 becomes the next digit in our result. 
Result so far: 12241.0
Subtracting 810 from 1345 leaves us with 535.
Include the next digit (0) from the dividend after 535, then repeat: 5350 / 810

Moving on to step 8:
810 can be fit into 5350 6 times, resulting in a remainder of 490.
The number 6 becomes the next digit in our result. 
Result so far: 122416.0
The remainder is 490 after subtracting 4860 from 5350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Advancing to step 9:
810 goes into 4900 6 times with a remainder of 40.
Use 6 as the next digit of our solution. 
Result so far: 122416.6
The remainder is 40 after subtracting 4860 from 4900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 10:
810 goes into 400 0 times with a remainder of 400.
The next digit of our result is 0. 
Result so far: 122416.6
The remainder is 400 after subtracting 0 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

On to step 11:
810 can be fit into 4000 4 times, resulting in a remainder of 760.
Record the quotient 4 as the next digit in the result. 
Result so far: 122416.604
If we take 3240 away from 4000, we end up with 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

Going ahead to step 12:
When dividing 7600 by 810, we get 9 with a remainder of 310.
The next digit of our result is 9. 
Result so far: 122416.6049
The remainder is 310 after subtracting 7290 from 7600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Advancing to step 13:
3100 divided by 810 is 3 with a remainder of 670.
The number 3 becomes the next digit in our result. 
Result so far: 122416.60493
The remainder is 670 after subtracting 2430 from 3100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6700, and continue the process.

Moving on to step 14:
If we divide 6700 by 810, we get 8 and a remainder of 220.
Use 8 as the next digit of our solution. 
Result so far: 122416.604938
Subtract 6480 from 6700 to get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Moving on to step 15:
If we divide 2200 by 810, we get 2 and a remainder of 580.
Use 2 as the next digit of our solution. 
Result so far: 122416.6049382
The remainder is 580 after subtracting 1620 from 2200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Advancing to step 16:
5800 divided by 810 is 7 with a remainder of 130.
The number 7 becomes the next digit in our result. 
Result so far: 122416.60493827
Subtracting 5670 from 5800 leaves us with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

In conclusion, the division gives 122416.60493827 with a balance of 1.3e-07.
