12549410 ÷ 604 
The aim is to understand the frequency of 604 in 12549410.

Let's proceed to step 1:
If we divide 1 by 604, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 604

Advancing to step 2:
604 goes into 12 0 times with a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Bring next digit (5) of the dividend behind the 12 and repeat the process: 125 / 604

Let's proceed to step 3:
The number 604 fits into 125 0 times, leaving a remainder of 125.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 125 and we're left with 125.
Grab the next digit (4) from the dividend, add it to 125, then carry on: 1254 / 604

Moving on to step 4:
The number 604 fits into 1254 2 times, leaving a remainder of 46.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 1208 from 1254 leaves us with 46.
Include the next digit (9) from the dividend after 46, then repeat: 469 / 604

Step 5:
The number 604 fits into 469 0 times, leaving a remainder of 469.
Use 0 as the next digit of our solution. 
Result so far: 20.0
Subtracting 0 from 469 leaves us with 469.
Grab the next digit (4) from the dividend, add it to 469, then carry on: 4694 / 604

Step 6:
The number 604 fits into 4694 7 times, leaving a remainder of 466.
The number 7 becomes the next digit in our result. 
Result so far: 207.0
If we subtract 4228 from 4694, we get 466.
Take the next digit (1) from the dividend and append it to 466, then repeat: 4661 / 604

Step 7:
4661 divided by 604 is 7 with a remainder of 433.
Use 7 as the next digit of our solution. 
Result so far: 2077.0
Subtract 4228 from 4661 to get 433.
Bring next digit (0) of the dividend behind the 433 and repeat the process: 4330 / 604

On to step 8:
604 can be fit into 4330 7 times, resulting in a remainder of 102.
Record the quotient 7 as the next digit in the result. 
Result so far: 20777.0
Subtract 4228 from 4330 to get 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Advancing to step 9:
When dividing 1020 by 604, we get 1 with a remainder of 416.
Write down 1 as next digit of the result. 
Result so far: 20777.1
Subtracting 604 from 1020 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:
4160 divided by 604 is 6 with a remainder of 536.
Write down 6 as next digit of the result. 
Result so far: 20777.16
The remainder is 536 after subtracting 3624 from 4160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5360, and continue the process.

Step 11:
604 can be fit into 5360 8 times, resulting in a remainder of 528.
Write down 8 as next digit of the result. 
Result so far: 20777.168
Subtracting 4832 from 5360 leaves us with 528.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

Going ahead to step 12:
604 goes into 5280 8 times with a remainder of 448.
The next digit of our result is 8. 
Result so far: 20777.1688
Deduct 4832 from 5280 and we're left with 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

The quotient of the division is 20777.1688, and the remainder is 0.00448.
