We're dividing 8147070 by 816 
The aim is to understand the frequency of 816 in 8147070.

Let's proceed to step 1:
When dividing 8 by 816, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 816

Going ahead to step 2:
If we divide 81 by 816, we get 0 and a remainder of 81.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 81 to get 81.
Bring next digit (4) of the dividend behind the 81 and repeat the process: 814 / 816

On to step 3:
816 can be fit into 814 0 times, resulting in a remainder of 814.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 814 to get 814.
Bring next digit (7) of the dividend behind the 814 and repeat the process: 8147 / 816

Moving on to step 4:
816 goes into 8147 9 times with a remainder of 803.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we take 7344 away from 8147, we end up with 803.
Include the next digit (0) from the dividend after 803, then repeat: 8030 / 816

Let's proceed to step 5:
816 can be fit into 8030 9 times, resulting in a remainder of 686.
Write down 9 as next digit of the result. 
Result so far: 99.0
Subtracting 7344 from 8030 leaves us with 686.
Bring next digit (7) of the dividend behind the 686 and repeat the process: 6867 / 816

On to step 6:
The number 816 fits into 6867 8 times, leaving a remainder of 339.
Use 8 as the next digit of our solution. 
Result so far: 998.0
The remainder is 339 after subtracting 6528 from 6867.
Include the next digit (0) from the dividend after 339, then repeat: 3390 / 816

On to step 7:
If we divide 3390 by 816, we get 4 and a remainder of 126.
Record the quotient 4 as the next digit in the result. 
Result so far: 9984.0
If we subtract 3264 from 3390, we get 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Advancing to step 8:
If we divide 1260 by 816, we get 1 and a remainder of 444.
The next digit of our result is 1. 
Result so far: 9984.1
Subtract 816 from 1260 to get 444.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4440, and continue the process.

On to step 9:
When dividing 4440 by 816, we get 5 with a remainder of 360.
The next digit of our result is 5. 
Result so far: 9984.15
Deduct 4080 from 4440 and we're left with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Let's proceed to step 10:
When dividing 3600 by 816, we get 4 with a remainder of 336.
Put 4 as the next digit of the answer. 
Result so far: 9984.154
Subtracting 3264 from 3600 leaves us with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Advancing to step 11:
816 goes into 3360 4 times with a remainder of 96.
The next digit of our result is 4. 
Result so far: 9984.1544
If we take 3264 away from 3360, we end up with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

The quotient of the division is 9984.1544, and the remainder is 0.00096.
