We're dividing 1550620 by 304 
The aim is to understand the frequency of 304 in 1550620.

Moving on to step 1:
304 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 304

Step 2:
304 can be fit into 15 0 times, resulting in a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 15 leaves us with 15.
Grab the next digit (5) from the dividend, add it to 15, then carry on: 155 / 304

Step 3:
When dividing 155 by 304, we get 0 with a remainder of 155.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 155, we get 155.
Include the next digit (0) from the dividend after 155, then repeat: 1550 / 304

Going ahead to step 4:
When dividing 1550 by 304, we get 5 with a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtract 1520 from 1550 to get 30.
Take the next digit (6) from the dividend and append it to 30, then repeat: 306 / 304

Step 5:
The number 304 fits into 306 1 times, leaving a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 51.0
Deduct 304 from 306 and we're left with 2.
Append the next digit (2) from the dividend to 2 and continue with: 22 / 304

Moving on to step 6:
The number 304 fits into 22 0 times, leaving a remainder of 22.
Put 0 as the next digit of the answer. 
Result so far: 510.0
If we subtract 0 from 22, we get 22.
Fetch the next digit (0) from the dividend, attach it to 22 and continue: 220 / 304

Moving on to step 7:
The number 304 fits into 220 0 times, leaving a remainder of 220.
Put 0 as the next digit of the answer. 
Result so far: 5100.0
If we subtract 0 from 220, we get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

On to step 8:
304 goes into 2200 7 times with a remainder of 72.
Write down 7 as next digit of the result. 
Result so far: 5100.7
If we take 2128 away from 2200, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 9:
If we divide 720 by 304, we get 2 and a remainder of 112.
The next digit of our result is 2. 
Result so far: 5100.72
If we subtract 608 from 720, we get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Going ahead to step 10:
If we divide 1120 by 304, we get 3 and a remainder of 208.
Use 3 as the next digit of our solution. 
Result so far: 5100.723
If we take 912 away from 1120, we end up with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Let's proceed to step 11:
The number 304 fits into 2080 6 times, leaving a remainder of 256.
Record the quotient 6 as the next digit in the result. 
Result so far: 5100.7236
Subtract 1824 from 2080 to get 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Advancing to step 12:
If we divide 2560 by 304, we get 8 and a remainder of 128.
Use 8 as the next digit of our solution. 
Result so far: 5100.72368
The remainder is 128 after subtracting 2432 from 2560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

On to step 13:
304 can be fit into 1280 4 times, resulting in a remainder of 64.
The number 4 becomes the next digit in our result. 
Result so far: 5100.723684
If we subtract 1216 from 1280, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 14:
When dividing 640 by 304, we get 2 with a remainder of 32.
The next digit of our result is 2. 
Result so far: 5100.7236842
Subtract 608 from 640 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 15:
320 divided by 304 is 1 with a remainder of 16.
The next digit of our result is 1. 
Result so far: 5100.72368421
Deduct 304 from 320 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final result is 5100.72368421 with a remainder of 1.6e-08.
