We divide 8309280 by 904
The aim is to understand the frequency of 904 in 8309280.

Moving on to step 1:
When dividing 8 by 904, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 904

Let's proceed to step 2:
904 can be fit into 83 0 times, resulting in a remainder of 83.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 83 and we're left with 83.
Fetch the next digit (0) from the dividend, attach it to 83 and continue: 830 / 904

Going ahead to step 3:
When dividing 830 by 904, we get 0 with a remainder of 830.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 830, we get 830.
Take the next digit (9) from the dividend and append it to 830, then repeat: 8309 / 904

Moving on to step 4:
The number 904 fits into 8309 9 times, leaving a remainder of 173.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we take 8136 away from 8309, we end up with 173.
Take the next digit (2) from the dividend and append it to 173, then repeat: 1732 / 904

Going ahead to step 5:
If we divide 1732 by 904, we get 1 and a remainder of 828.
The number 1 becomes the next digit in our result. 
Result so far: 91.0
The remainder is 828 after subtracting 904 from 1732.
Fetch the next digit (8) from the dividend, attach it to 828 and continue: 8288 / 904

Advancing to step 6:
8288 divided by 904 is 9 with a remainder of 152.
The next digit of our result is 9. 
Result so far: 919.0
If we take 8136 away from 8288, we end up with 152.
Include the next digit (0) from the dividend after 152, then repeat: 1520 / 904

Step 7:
If we divide 1520 by 904, we get 1 and a remainder of 616.
The next digit of our result is 1. 
Result so far: 9191.0
Subtract 904 from 1520 to get 616.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6160, and continue the process.

Moving on to step 8:
904 goes into 6160 6 times with a remainder of 736.
Record the quotient 6 as the next digit in the result. 
Result so far: 9191.6
If we subtract 5424 from 6160, we get 736.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7360, and continue the process.

Step 9:
904 can be fit into 7360 8 times, resulting in a remainder of 128.
Record the quotient 8 as the next digit in the result. 
Result so far: 9191.68
Subtract 7232 from 7360 to get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

On to step 10:
If we divide 1280 by 904, we get 1 and a remainder of 376.
Write down 1 as next digit of the result. 
Result so far: 9191.681
Subtracting 904 from 1280 leaves us with 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Let's proceed to step 11:
When dividing 3760 by 904, we get 4 with a remainder of 144.
Write down 4 as next digit of the result. 
Result so far: 9191.6814
If we take 3616 away from 3760, we end up with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

On to step 12:
904 can be fit into 1440 1 times, resulting in a remainder of 536.
The number 1 becomes the next digit in our result. 
Result so far: 9191.68141
If we subtract 904 from 1440, we get 536.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5360, and continue the process.

On to step 13:
The number 904 fits into 5360 5 times, leaving a remainder of 840.
Record the quotient 5 as the next digit in the result. 
Result so far: 9191.681415
If we subtract 4520 from 5360, we get 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8400, and continue the process.

Moving on to step 14:
8400 divided by 904 is 9 with a remainder of 264.
Put 9 as the next digit of the answer. 
Result so far: 9191.6814159
If we take 8136 away from 8400, we end up with 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Advancing to step 15:
If we divide 2640 by 904, we get 2 and a remainder of 832.
Put 2 as the next digit of the answer. 
Result so far: 9191.68141592
If we take 1808 away from 2640, we end up with 832.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8320, and continue the process.

The quotient of the division is 9191.68141592, and the remainder is 8.32e-07.
