We look at the division of 54661297 by 804 
The aim is to understand the frequency of 804 in 54661297.

Moving on to step 1:
The number 804 fits into 5 0 times, leaving a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Include the next digit (4) from the dividend after 5, then repeat: 54 / 804

Moving on to step 2:
When dividing 54 by 804, we get 0 with a remainder of 54.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 54, we get 54.
Bring next digit (6) of the dividend behind the 54 and repeat the process: 546 / 804

Let's proceed to step 3:
When dividing 546 by 804, we get 0 with a remainder of 546.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 546 after subtracting 0 from 546.
Take the next digit (6) from the dividend and append it to 546, then repeat: 5466 / 804

Let's proceed to step 4:
When dividing 5466 by 804, we get 6 with a remainder of 642.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Subtracting 4824 from 5466 leaves us with 642.
Take the next digit (1) from the dividend and append it to 642, then repeat: 6421 / 804

Advancing to step 5:
804 can be fit into 6421 7 times, resulting in a remainder of 793.
The next digit of our result is 7. 
Result so far: 67.0
Deduct 5628 from 6421 and we're left with 793.
Grab the next digit (2) from the dividend, add it to 793, then carry on: 7932 / 804

Moving on to step 6:
804 goes into 7932 9 times with a remainder of 696.
The next digit of our result is 9. 
Result so far: 679.0
If we take 7236 away from 7932, we end up with 696.
Append the next digit (9) from the dividend to 696 and continue with: 6969 / 804

Advancing to step 7:
804 goes into 6969 8 times with a remainder of 537.
Write down 8 as next digit of the result. 
Result so far: 6798.0
If we subtract 6432 from 6969, we get 537.
Fetch the next digit (7) from the dividend, attach it to 537 and continue: 5377 / 804

Going ahead to step 8:
5377 divided by 804 is 6 with a remainder of 553.
Write down 6 as next digit of the result. 
Result so far: 67986.0
If we take 4824 away from 5377, we end up with 553.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5530, and continue the process.

Going ahead to step 9:
5530 divided by 804 is 6 with a remainder of 706.
The next digit of our result is 6. 
Result so far: 67986.6
If we subtract 4824 from 5530, we get 706.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7060, and continue the process.

Let's proceed to step 10:
The number 804 fits into 7060 8 times, leaving a remainder of 628.
The number 8 becomes the next digit in our result. 
Result so far: 67986.68
Deduct 6432 from 7060 and we're left with 628.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6280, and continue the process.

Moving on to step 11:
When dividing 6280 by 804, we get 7 with a remainder of 652.
Use 7 as the next digit of our solution. 
Result so far: 67986.687
If we take 5628 away from 6280, we end up with 652.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6520, and continue the process.

Advancing to step 12:
6520 divided by 804 is 8 with a remainder of 88.
Record the quotient 8 as the next digit in the result. 
Result so far: 67986.6878
If we subtract 6432 from 6520, we get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Let's proceed to step 13:
When dividing 880 by 804, we get 1 with a remainder of 76.
The number 1 becomes the next digit in our result. 
Result so far: 67986.68781
Subtract 804 from 880 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 14:
If we divide 760 by 804, we get 0 and a remainder of 760.
The number 0 becomes the next digit in our result. 
Result so far: 67986.68781
If we take 0 away from 760, we end up with 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

On to step 15:
804 can be fit into 7600 9 times, resulting in a remainder of 364.
Use 9 as the next digit of our solution. 
Result so far: 67986.6878109
If we subtract 7236 from 7600, we get 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Step 16:
When dividing 3640 by 804, we get 4 with a remainder of 424.
The number 4 becomes the next digit in our result. 
Result so far: 67986.68781094
Subtracting 3216 from 3640 leaves us with 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

The final outcome is 67986.68781094, with a leftover of 4.24e-07.
