We're dividing 14370907 by 816 
The aim is to understand the frequency of 816 in 14370907.

Step 1:
816 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 816

Let's proceed to step 2:
When dividing 14 by 816, we get 0 with a remainder of 14.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 14 to get 14.
Append the next digit (3) from the dividend to 14 and continue with: 143 / 816

Advancing to step 3:
143 divided by 816 is 0 with a remainder of 143.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 143 leaves us with 143.
Grab the next digit (7) from the dividend, add it to 143, then carry on: 1437 / 816

On to step 4:
816 goes into 1437 1 times with a remainder of 621.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 816 from 1437 leaves us with 621.
Grab the next digit (0) from the dividend, add it to 621, then carry on: 6210 / 816

Let's proceed to step 5:
6210 divided by 816 is 7 with a remainder of 498.
The next digit of our result is 7. 
Result so far: 17.0
Subtracting 5712 from 6210 leaves us with 498.
Include the next digit (9) from the dividend after 498, then repeat: 4989 / 816

Moving on to step 6:
816 goes into 4989 6 times with a remainder of 93.
Use 6 as the next digit of our solution. 
Result so far: 176.0
Subtract 4896 from 4989 to get 93.
Grab the next digit (0) from the dividend, add it to 93, then carry on: 930 / 816

On to step 7:
When dividing 930 by 816, we get 1 with a remainder of 114.
Use 1 as the next digit of our solution. 
Result so far: 1761.0
Subtracting 816 from 930 leaves us with 114.
Bring next digit (7) of the dividend behind the 114 and repeat the process: 1147 / 816

Advancing to step 8:
If we divide 1147 by 816, we get 1 and a remainder of 331.
The number 1 becomes the next digit in our result. 
Result so far: 17611.0
Subtract 816 from 1147 to get 331.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3310, and continue the process.

Step 9:
3310 divided by 816 is 4 with a remainder of 46.
The next digit of our result is 4. 
Result so far: 17611.4
Subtract 3264 from 3310 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 10:
If we divide 460 by 816, we get 0 and a remainder of 460.
The number 0 becomes the next digit in our result. 
Result so far: 17611.4
If we take 0 away from 460, we end up with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

On to step 11:
The number 816 fits into 4600 5 times, leaving a remainder of 520.
The next digit of our result is 5. 
Result so far: 17611.405
Subtract 4080 from 4600 to get 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Going ahead to step 12:
If we divide 5200 by 816, we get 6 and a remainder of 304.
The next digit of our result is 6. 
Result so far: 17611.4056
Deduct 4896 from 5200 and we're left with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Advancing to step 13:
When dividing 3040 by 816, we get 3 with a remainder of 592.
The number 3 becomes the next digit in our result. 
Result so far: 17611.40563
Subtracting 2448 from 3040 leaves us with 592.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5920, and continue the process.

Going ahead to step 14:
816 goes into 5920 7 times with a remainder of 208.
The next digit of our result is 7. 
Result so far: 17611.405637
If we subtract 5712 from 5920, we get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Let's proceed to step 15:
If we divide 2080 by 816, we get 2 and a remainder of 448.
Record the quotient 2 as the next digit in the result. 
Result so far: 17611.4056372
The remainder is 448 after subtracting 1632 from 2080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Moving on to step 16:
816 goes into 4480 5 times with a remainder of 400.
Record the quotient 5 as the next digit in the result. 
Result so far: 17611.40563725
Deduct 4080 from 4480 and we're left with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

The quotient of the division is 17611.40563725, and the remainder is 4e-07.
