98624963 divided by 816 
The aim is to understand the frequency of 816 in 98624963.

Advancing to step 1:
The number 816 fits into 9 0 times, leaving a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Grab the next digit (8) from the dividend, add it to 9, then carry on: 98 / 816

Let's proceed to step 2:
When dividing 98 by 816, we get 0 with a remainder of 98.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 98, we get 98.
Include the next digit (6) from the dividend after 98, then repeat: 986 / 816

Step 3:
The number 816 fits into 986 1 times, leaving a remainder of 170.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 816 from 986 to get 170.
Bring next digit (2) of the dividend behind the 170 and repeat the process: 1702 / 816

Moving on to step 4:
816 goes into 1702 2 times with a remainder of 70.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
If we subtract 1632 from 1702, we get 70.
Include the next digit (4) from the dividend after 70, then repeat: 704 / 816

Moving on to step 5:
816 can be fit into 704 0 times, resulting in a remainder of 704.
Use 0 as the next digit of our solution. 
Result so far: 120.0
If we subtract 0 from 704, we get 704.
Bring next digit (9) of the dividend behind the 704 and repeat the process: 7049 / 816

Let's proceed to step 6:
816 goes into 7049 8 times with a remainder of 521.
Put 8 as the next digit of the answer. 
Result so far: 1208.0
If we take 6528 away from 7049, we end up with 521.
Bring next digit (6) of the dividend behind the 521 and repeat the process: 5216 / 816

Advancing to step 7:
The number 816 fits into 5216 6 times, leaving a remainder of 320.
The next digit of our result is 6. 
Result so far: 12086.0
If we subtract 4896 from 5216, we get 320.
Include the next digit (3) from the dividend after 320, then repeat: 3203 / 816

Step 8:
When dividing 3203 by 816, we get 3 with a remainder of 755.
The next digit of our result is 3. 
Result so far: 120863.0
If we take 2448 away from 3203, we end up with 755.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7550, and continue the process.

Going ahead to step 9:
816 can be fit into 7550 9 times, resulting in a remainder of 206.
Put 9 as the next digit of the answer. 
Result so far: 120863.9
Subtract 7344 from 7550 to get 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

Step 10:
2060 divided by 816 is 2 with a remainder of 428.
Put 2 as the next digit of the answer. 
Result so far: 120863.92
Subtract 1632 from 2060 to get 428.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

Advancing to step 11:
4280 divided by 816 is 5 with a remainder of 200.
Put 5 as the next digit of the answer. 
Result so far: 120863.925
The remainder is 200 after subtracting 4080 from 4280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

On to step 12:
2000 divided by 816 is 2 with a remainder of 368.
Put 2 as the next digit of the answer. 
Result so far: 120863.9252
If we subtract 1632 from 2000, we get 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Step 13:
The number 816 fits into 3680 4 times, leaving a remainder of 416.
Use 4 as the next digit of our solution. 
Result so far: 120863.92524
Deduct 3264 from 3680 and we're left with 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Advancing to step 14:
If we divide 4160 by 816, we get 5 and a remainder of 80.
Use 5 as the next digit of our solution. 
Result so far: 120863.925245
Subtract 4080 from 4160 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 15:
816 can be fit into 800 0 times, resulting in a remainder of 800.
The next digit of our result is 0. 
Result so far: 120863.925245
Subtract 0 from 800 to get 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

Let's proceed to step 16:
816 can be fit into 8000 9 times, resulting in a remainder of 656.
Use 9 as the next digit of our solution. 
Result so far: 120863.92524509
Subtract 7344 from 8000 to get 656.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6560, and continue the process.

The final outcome is 120863.92524509, with a leftover of 6.56e-07.
