We look at the division of 27615563 by 804 
The aim is to understand the frequency of 804 in 27615563.

On to step 1:
2 divided by 804 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 804

Advancing to step 2:
27 divided by 804 is 0 with a remainder of 27.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 27, we end up with 27.
Grab the next digit (6) from the dividend, add it to 27, then carry on: 276 / 804

Going ahead to step 3:
804 can be fit into 276 0 times, resulting in a remainder of 276.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 276, we end up with 276.
Take the next digit (1) from the dividend and append it to 276, then repeat: 2761 / 804

Let's proceed to step 4:
804 goes into 2761 3 times with a remainder of 349.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we subtract 2412 from 2761, we get 349.
Append the next digit (5) from the dividend to 349 and continue with: 3495 / 804

Moving on to step 5:
When dividing 3495 by 804, we get 4 with a remainder of 279.
Put 4 as the next digit of the answer. 
Result so far: 34.0
If we subtract 3216 from 3495, we get 279.
Bring next digit (5) of the dividend behind the 279 and repeat the process: 2795 / 804

Let's proceed to step 6:
The number 804 fits into 2795 3 times, leaving a remainder of 383.
Use 3 as the next digit of our solution. 
Result so far: 343.0
Deduct 2412 from 2795 and we're left with 383.
Append the next digit (6) from the dividend to 383 and continue with: 3836 / 804

On to step 7:
If we divide 3836 by 804, we get 4 and a remainder of 620.
Record the quotient 4 as the next digit in the result. 
Result so far: 3434.0
Subtracting 3216 from 3836 leaves us with 620.
Include the next digit (3) from the dividend after 620, then repeat: 6203 / 804

Step 8:
When dividing 6203 by 804, we get 7 with a remainder of 575.
The number 7 becomes the next digit in our result. 
Result so far: 34347.0
Subtracting 5628 from 6203 leaves us with 575.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5750, and continue the process.

Going ahead to step 9:
804 can be fit into 5750 7 times, resulting in a remainder of 122.
Record the quotient 7 as the next digit in the result. 
Result so far: 34347.7
If we subtract 5628 from 5750, we get 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Moving on to step 10:
The number 804 fits into 1220 1 times, leaving a remainder of 416.
The number 1 becomes the next digit in our result. 
Result so far: 34347.71
Subtract 804 from 1220 to get 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Going ahead to step 11:
804 can be fit into 4160 5 times, resulting in a remainder of 140.
The next digit of our result is 5. 
Result so far: 34347.715
Subtract 4020 from 4160 to 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.

Let's proceed to step 12:
1400 divided by 804 is 1 with a remainder of 596.
Put 1 as the next digit of the answer. 
Result so far: 34347.7151
If we subtract 804 from 1400, we 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 13:
804 goes into 5960 7 times with a remainder of 332.
Record the quotient 7 as the next digit in the result. 
Result so far: 34347.71517
If we subtract 5628 from 5960, we get 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

Moving on to step 14:
If we divide 3320 by 804, we get 4 and a remainder of 104.
The number 4 becomes the next digit in our result. 
Result so far: 34347.715174
If we subtract 3216 from 3320, we 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.

Advancing to step 15:
When dividing 1040 by 804, we get 1 with a remainder of 236.
Record the quotient 1 as the next digit in the result. 
Result so far: 34347.7151741
Subtract 804 from 1040 to get 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Step 16:
2360 divided by 804 is 2 with a remainder of 752.
Write down 2 as next digit of the result. 
Result so far: 34347.71517412
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.

Our division results in 34347.71517412 with a remaining 7.52e-07.
