86604027 divided by 600 
The aim is to understand the frequency of 600 in 86604027.

Moving on to step 1:
8 divided by 600 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 600

Going ahead to step 2:
600 can be fit into 86 0 times, resulting in a remainder of 86.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 86 leaves us with 86.
Grab the next digit (6) from the dividend, add it to 86, then carry on: 866 / 600

Moving on to step 3:
The number 600 fits into 866 1 times, leaving a remainder of 266.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 600 from 866 to get 266.
Fetch the next digit (0) from the dividend, attach it to 266 and continue: 2660 / 600

Let's proceed to step 4:
The number 600 fits into 2660 4 times, leaving a remainder of 260.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
If we subtract 2400 from 2660, we get 260.
Fetch the next digit (4) from the dividend, attach it to 260 and continue: 2604 / 600

Let's proceed to step 5:
600 goes into 2604 4 times with a remainder of 204.
Put 4 as the next digit of the answer. 
Result so far: 144.0
If we subtract 2400 from 2604, we get 204.
Include the next digit (0) from the dividend after 204, then repeat: 2040 / 600

Moving on to step 6:
2040 divided by 600 is 3 with a remainder of 240.
Use 3 as the next digit of our solution. 
Result so far: 1443.0
If we take 1800 away from 2040, we end up with 240.
Bring next digit (2) of the dividend behind the 240 and repeat the process: 2402 / 600

On to step 7:
600 goes into 2402 4 times with a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 14434.0
If we take 2400 away from 2402, we end up with 2.
Grab the next digit (7) from the dividend, add it to 2, then carry on: 27 / 600

Moving on to step 8:
600 can be fit into 27 0 times, resulting in a remainder of 27.
Use 0 as the next digit of our solution. 
Result so far: 144340.0
Deduct 0 from 27 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 9:
270 divided by 600 is 0 with a remainder of 270.
The number 0 becomes the next digit in our result. 
Result so far: 144340.0
If we take 0 away from 270, we end up with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Let's proceed to step 10:
If we divide 2700 by 600, we get 4 and a remainder of 300.
The next digit of our result is 4. 
Result so far: 144340.04
Deduct 2400 from 2700 and we're left with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Moving on to step 11:
3000 divided by 600 is 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 144340.045
The remainder is 0 after subtracting 3000 from 3000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 12:
600 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 144340.045
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 13:
When dividing 0 by 600, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 144340.045
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 144340.045 with a remainder of 0.0.
