We divide 99208063 by 815
The aim is to understand the frequency of 815 in 99208063.

Advancing to step 1:
If we divide 9 by 815, we get 0 and a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 815

Going ahead to step 2:
When dividing 99 by 815, we get 0 with a remainder of 99.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 99, we end up with 99.
Fetch the next digit (2) from the dividend, attach it to 99 and continue: 992 / 815

Step 3:
815 can be fit into 992 1 times, resulting in a remainder of 177.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 815 from 992 to get 177.
Append the next digit (0) from the dividend to 177 and continue with: 1770 / 815

Step 4:
The number 815 fits into 1770 2 times, leaving a remainder of 140.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Deduct 1630 from 1770 and we're left with 140.
Include the next digit (8) from the dividend after 140, then repeat: 1408 / 815

Let's proceed to step 5:
815 can be fit into 1408 1 times, resulting in a remainder of 593.
Put 1 as the next digit of the answer. 
Result so far: 121.0
Deduct 815 from 1408 and we're left with 593.
Grab the next digit (0) from the dividend, add it to 593, then carry on: 5930 / 815

Advancing to step 6:
815 can be fit into 5930 7 times, resulting in a remainder of 225.
Use 7 as the next digit of our solution. 
Result so far: 1217.0
If we take 5705 away from 5930, we end up with 225.
Take the next digit (6) from the dividend and append it to 225, then repeat: 2256 / 815

Let's proceed to step 7:
If we divide 2256 by 815, we get 2 and a remainder of 626.
Put 2 as the next digit of the answer. 
Result so far: 12172.0
Subtract 1630 from 2256 to get 626.
Append the next digit (3) from the dividend to 626 and continue with: 6263 / 815

Going ahead to step 8:
815 can be fit into 6263 7 times, resulting in a remainder of 558.
The number 7 becomes the next digit in our result. 
Result so far: 121727.0
The remainder is 558 after subtracting 5705 from 6263.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5580, and continue the process.

Advancing to step 9:
815 goes into 5580 6 times with a remainder of 690.
Put 6 as the next digit of the answer. 
Result so far: 121727.6
If we subtract 4890 from 5580, we get 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6900, and continue the process.

Let's proceed to step 10:
815 can be fit into 6900 8 times, resulting in a remainder of 380.
Record the quotient 8 as the next digit in the result. 
Result so far: 121727.68
Deduct 6520 from 6900 and we're left with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Step 11:
3800 divided by 815 is 4 with a remainder of 540.
Record the quotient 4 as the next digit in the result. 
Result so far: 121727.684
Deduct 3260 from 3800 and we're left with 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Step 12:
815 can be fit into 5400 6 times, resulting in a remainder of 510.
Use 6 as the next digit of our solution. 
Result so far: 121727.6846
Subtract 4890 from 5400 to get 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

Going ahead to step 13:
815 goes into 5100 6 times with a remainder of 210.
Use 6 as the next digit of our solution. 
Result so far: 121727.68466
Deduct 4890 from 5100 and we're left with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

The final outcome is 121727.68466, with a leftover of 0.00021.
