We look at the division of 96404546 by 804 
The aim is to understand the frequency of 804 in 96404546.

Moving on to step 1:
If we divide 9 by 804, we get 0 and a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Append the next digit (6) from the dividend to 9 and continue with: 96 / 804

On to step 2:
When dividing 96 by 804, we get 0 with a remainder of 96.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 96 leaves us with 96.
Bring next digit (4) of the dividend behind the 96 and repeat the process: 964 / 804

Let's proceed to step 3:
804 goes into 964 1 times with a remainder of 160.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 804 from 964 leaves us with 160.
Fetch the next digit (0) from the dividend, attach it to 160 and continue: 1600 / 804

Step 4:
The number 804 fits into 1600 1 times, leaving a remainder of 796.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Subtracting 804 from 1600 leaves us with 796.
Bring next digit (4) of the dividend behind the 796 and repeat the process: 7964 / 804

Moving on to step 5:
804 goes into 7964 9 times with a remainder of 728.
The number 9 becomes the next digit in our result. 
Result so far: 119.0
Deduct 7236 from 7964 and we're left with 728.
Fetch the next digit (5) from the dividend, attach it to 728 and continue: 7285 / 804

Step 6:
7285 divided by 804 is 9 with a remainder of 49.
Record the quotient 9 as the next digit in the result. 
Result so far: 1199.0
Deduct 7236 from 7285 and we're left with 49.
Append the next digit (4) from the dividend to 49 and continue with: 494 / 804

Going ahead to step 7:
804 goes into 494 0 times with a remainder of 494.
The number 0 becomes the next digit in our result. 
Result so far: 11990.0
Subtract 0 from 494 to get 494.
Grab the next digit (6) from the dividend, add it to 494, then carry on: 4946 / 804

Step 8:
If we divide 4946 by 804, we get 6 and a remainder of 122.
Put 6 as the next digit of the answer. 
Result so far: 119906.0
Subtracting 4824 from 4946 leaves us with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

On to step 9:
804 can be fit into 1220 1 times, resulting in a remainder of 416.
Use 1 as the next digit of our solution. 
Result so far: 119906.1
Subtracting 804 from 1220 leaves us 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.

Let's proceed to step 10:
The number 804 fits into 4160 5 times, leaving a remainder of 140.
Put 5 as the next digit of the answer. 
Result so far: 119906.15
If we subtract 4020 from 4160, we get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Moving on to step 11:
804 goes into 1400 1 times with a remainder of 596.
Use 1 as the next digit of our solution. 
Result so far: 119906.151
Subtract 804 from 1400 to get 596.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5960, and continue the process.

On to step 12:
804 can be fit into 5960 7 times, resulting in a remainder of 332.
Use 7 as the next digit of our solution. 
Result so far: 119906.1517
Deduct 5628 from 5960 and we're left with 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

Step 13:
804 can be fit into 3320 4 times, resulting in a remainder of 104.
The next digit of our result is 4. 
Result so far: 119906.15174
Subtract 3216 from 3320 to get 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

On to step 14:
1040 divided by 804 is 1 with a remainder of 236.
The next digit of our result is 1. 
Result so far: 119906.151741
If we take 804 away from 1040, we end up with 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Moving on to step 15:
804 goes into 2360 2 times with a remainder of 752.
Put 2 as the next digit of the answer. 
Result so far: 119906.1517412
The remainder is 752 after subtracting 1608 from 2360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7520, and continue the process.

Step 16:
When dividing 7520 by 804, we get 9 with a remainder of 284.
Put 9 as the next digit of the answer. 
Result so far: 119906.15174129
If we take 7236 away from 7520, we end up with 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

The final result is 119906.15174129 with a remainder of 2.84e-07.
