We look at the division of 81056037 by 600 
The aim is to understand the frequency of 600 in 81056037.

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
Subtract 0 from 8 to get 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 600

On to step 2:
81 divided by 600 is 0 with a remainder of 81.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 81 after subtracting 0 from 81.
Grab the next digit (0) from the dividend, add it to 81, then carry on: 810 / 600

Step 3:
When dividing 810 by 600, we get 1 with a remainder of 210.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 600 from 810 and we're left with 210.
Take the next digit (5) from the dividend and append it to 210, then repeat: 2105 / 600

Advancing to step 4:
If we divide 2105 by 600, we get 3 and a remainder of 305.
Put 3 as the next digit of the answer. 
Result so far: 13.0
If we take 1800 away from 2105, we end up with 305.
Append the next digit (6) from the dividend to 305 and continue with: 3056 / 600

Moving on to step 5:
When dividing 3056 by 600, we get 5 with a remainder of 56.
The next digit of our result is 5. 
Result so far: 135.0
Deduct 3000 from 3056 and we're left with 56.
Include the next digit (0) from the dividend after 56, then repeat: 560 / 600

Advancing to step 6:
When dividing 560 by 600, we get 0 with a remainder of 560.
Record the quotient 0 as the next digit in the result. 
Result so far: 1350.0
The remainder is 560 after subtracting 0 from 560.
Include the next digit (3) from the dividend after 560, then repeat: 5603 / 600

Advancing to step 7:
600 goes into 5603 9 times with a remainder of 203.
Use 9 as the next digit of our solution. 
Result so far: 13509.0
Subtracting 5400 from 5603 leaves us with 203.
Take the next digit (7) from the dividend and append it to 203, then repeat: 2037 / 600

Moving on to step 8:
When dividing 2037 by 600, we get 3 with a remainder of 237.
The number 3 becomes the next digit in our result. 
Result so far: 135093.0
If we subtract 1800 from 2037, we get 237.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2370, and continue the process.

Step 9:
600 can be fit into 2370 3 times, resulting in a remainder of 570.
The next digit of our result is 3. 
Result so far: 135093.3
Deduct 1800 from 2370 and we're left with 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5700, and continue the process.

On to step 10:
If we divide 5700 by 600, we get 9 and a remainder of 300.
Write down 9 as next digit of the result. 
Result so far: 135093.39
If we take 5400 away from 5700, we end up 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.

Advancing to step 11:
The number 600 fits into 3000 5 times, leaving a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 135093.395
Subtract 3000 from 3000 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 12:
The number 600 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 135093.395
Deduct 0 from 0 and we're left 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.

Let's proceed to step 13:
When dividing 0 by 600, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 135093.395
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.

After the division, we end up with 135093.395 and a remainder of 0.0.
