We look at the division of 26571806 by 604 
The aim is to understand the frequency of 604 in 26571806.

Moving on to step 1:
2 divided by 604 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Take the next digit (6) from the dividend and append it to 2, then repeat: 26 / 604

On to step 2:
604 can be fit into 26 0 times, resulting in a remainder of 26.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 26 and we're left with 26.
Include the next digit (5) from the dividend after 26, then repeat: 265 / 604

On to step 3:
604 goes into 265 0 times with a remainder of 265.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 265 leaves us with 265.
Include the next digit (7) from the dividend after 265, then repeat: 2657 / 604

Going ahead to step 4:
604 goes into 2657 4 times with a remainder of 241.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we subtract 2416 from 2657, we get 241.
Grab the next digit (1) from the dividend, add it to 241, then carry on: 2411 / 604

Moving on to step 5:
The number 604 fits into 2411 3 times, leaving a remainder of 599.
Record the quotient 3 as the next digit in the result. 
Result so far: 43.0
Subtract 1812 from 2411 to get 599.
Bring next digit (8) of the dividend behind the 599 and repeat the process: 5998 / 604

Let's proceed to step 6:
When dividing 5998 by 604, we get 9 with a remainder of 562.
The number 9 becomes the next digit in our result. 
Result so far: 439.0
If we subtract 5436 from 5998, we get 562.
Bring next digit (0) of the dividend behind the 562 and repeat the process: 5620 / 604

On to step 7:
The number 604 fits into 5620 9 times, leaving a remainder of 184.
Put 9 as the next digit of the answer. 
Result so far: 4399.0
If we subtract 5436 from 5620, we get 184.
Fetch the next digit (6) from the dividend, attach it to 184 and continue: 1846 / 604

Going ahead to step 8:
If we divide 1846 by 604, we get 3 and a remainder of 34.
Write down 3 as next digit of the result. 
Result so far: 43993.0
Subtracting 1812 from 1846 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 9:
604 goes into 340 0 times with a remainder of 340.
Write down 0 as next digit of the result. 
Result so far: 43993.0
If we take 0 away from 340, we end up with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Advancing to step 10:
When dividing 3400 by 604, we get 5 with a remainder of 380.
The next digit of our result is 5. 
Result so far: 43993.05
Deduct 3020 from 3400 and we're left with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Let's proceed to step 11:
The number 604 fits into 3800 6 times, leaving a remainder of 176.
The next digit of our result is 6. 
Result so far: 43993.056
If we subtract 3624 from 3800, we get 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Step 12:
1760 divided by 604 is 2 with a remainder of 552.
Use 2 as the next digit of our solution. 
Result so far: 43993.0562
If we subtract 1208 from 1760, we get 552.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5520, and continue the process.

Going ahead to step 13:
When dividing 5520 by 604, we get 9 with a remainder of 84.
Put 9 as the next digit of the answer. 
Result so far: 43993.05629
If we take 5436 away from 5520, we end up with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

On to step 14:
840 divided by 604 is 1 with a remainder of 236.
Use 1 as the next digit of our solution. 
Result so far: 43993.056291
Subtract 604 from 840 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.

Going ahead to step 15:
2360 divided by 604 is 3 with a remainder of 548.
Record the quotient 3 as the next digit in the result. 
Result so far: 43993.0562913
Subtracting 1812 from 2360 leaves us with 548.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5480, and continue the process.

Going ahead to step 16:
The number 604 fits into 5480 9 times, leaving a remainder of 44.
Use 9 as the next digit of our solution. 
Result so far: 43993.05629139
Deduct 5436 from 5480 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

In conclusion, the division gives 43993.05629139 with a balance of 4.4e-08.
