We look at the division of 67478551 by 804 
The aim is to understand the frequency of 804 in 67478551.

Let's proceed to step 1:
804 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (7) from the dividend after 6, then repeat: 67 / 804

Let's proceed to step 2:
804 goes into 67 0 times with a remainder of 67.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 67 after subtracting 0 from 67.
Fetch the next digit (4) from the dividend, attach it to 67 and continue: 674 / 804

On to step 3:
The number 804 fits into 674 0 times, leaving a remainder of 674.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 674 to get 674.
Include the next digit (7) from the dividend after 674, then repeat: 6747 / 804

Going ahead to step 4:
804 goes into 6747 8 times with a remainder of 315.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Deduct 6432 from 6747 and we're left with 315.
Grab the next digit (8) from the dividend, add it to 315, then carry on: 3158 / 804

Step 5:
3158 divided by 804 is 3 with a remainder of 746.
Record the quotient 3 as the next digit in the result. 
Result so far: 83.0
The remainder is 746 after subtracting 2412 from 3158.
Bring next digit (5) of the dividend behind the 746 and repeat the process: 7465 / 804

Going ahead to step 6:
7465 divided by 804 is 9 with a remainder of 229.
Put 9 as the next digit of the answer. 
Result so far: 839.0
If we subtract 7236 from 7465, we get 229.
Take the next digit (5) from the dividend and append it to 229, then repeat: 2295 / 804

On to step 7:
When dividing 2295 by 804, we get 2 with a remainder of 687.
The number 2 becomes the next digit in our result. 
Result so far: 8392.0
Subtract 1608 from 2295 to get 687.
Fetch the next digit (1) from the dividend, attach it to 687 and continue: 6871 / 804

Going ahead to step 8:
6871 divided by 804 is 8 with a remainder of 439.
The number 8 becomes the next digit in our result. 
Result so far: 83928.0
Deduct 6432 from 6871 and we're left with 439.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4390, and continue the process.

On to step 9:
804 can be fit into 4390 5 times, resulting in a remainder of 370.
Record the quotient 5 as the next digit in the result. 
Result so far: 83928.5
If we take 4020 away from 4390, we end up with 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Moving on to step 10:
When dividing 3700 by 804, we get 4 with a remainder of 484.
The number 4 becomes the next digit in our result. 
Result so far: 83928.54
Deduct 3216 from 3700 and we're left with 484.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4840, and continue the process.

Going ahead to step 11:
If we divide 4840 by 804, we get 6 and a remainder of 16.
Record the quotient 6 as the next digit in the result. 
Result so far: 83928.546
Subtract 4824 from 4840 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 12:
804 can be fit into 160 0 times, resulting in a remainder of 160.
Record the quotient 0 as the next digit in the result. 
Result so far: 83928.546
If we take 0 away from 160, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Going ahead to step 13:
804 goes into 1600 1 times with a remainder of 796.
Write down 1 as next digit of the result. 
Result so far: 83928.54601
Subtract 804 from 1600 to get 796.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7960, and continue the process.

Moving on to step 14:
If we divide 7960 by 804, we get 9 and a remainder of 724.
Put 9 as the next digit of the answer. 
Result so far: 83928.546019
If we take 7236 away from 7960, we end up with 724.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7240, and continue the process.

Going ahead to step 15:
The number 804 fits into 7240 9 times, leaving a remainder of 4.
Record the quotient 9 as the next digit in the result. 
Result so far: 83928.5460199
Deduct 7236 from 7240 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Our division results in 83928.5460199 with a remaining 4e-08.
