We look at the division of 26503969 by 600 
The aim is to understand the frequency of 600 in 26503969.

On to step 1:
When dividing 2 by 600, we get 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Bring next digit (6) of the dividend behind the 2 and repeat the process: 26 / 600

Step 2:
600 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.
Grab the next digit (5) from the dividend, add it to 26, then carry on: 265 / 600

Moving on to step 3:
The number 600 fits into 265 0 times, leaving a remainder of 265.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 265 and we're left with 265.
Take the next digit (0) from the dividend and append it to 265, then repeat: 2650 / 600

Going ahead to step 4:
When dividing 2650 by 600, we get 4 with a remainder of 250.
The next digit of our result is 4. 
Result so far: 4.0
If we take 2400 away from 2650, we end up with 250.
Include the next digit (3) from the dividend after 250, then repeat: 2503 / 600

Advancing to step 5:
600 can be fit into 2503 4 times, resulting in a remainder of 103.
The number 4 becomes the next digit in our result. 
Result so far: 44.0
The remainder is 103 after subtracting 2400 from 2503.
Take the next digit (9) from the dividend and append it to 103, then repeat: 1039 / 600

Going ahead to step 6:
The number 600 fits into 1039 1 times, leaving a remainder of 439.
The next digit of our result is 1. 
Result so far: 441.0
The remainder is 439 after subtracting 600 from 1039.
Bring next digit (6) of the dividend behind the 439 and repeat the process: 4396 / 600

Step 7:
600 goes into 4396 7 times with a remainder of 196.
The next digit of our result is 7. 
Result so far: 4417.0
The remainder is 196 after subtracting 4200 from 4396.
Include the next digit (9) from the dividend after 196, then repeat: 1969 / 600

Going ahead to step 8:
When dividing 1969 by 600, we get 3 with a remainder of 169.
Put 3 as the next digit of the answer. 
Result so far: 44173.0
Deduct 1800 from 1969 and we're left with 169.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1690, and continue the process.

Advancing to step 9:
The number 600 fits into 1690 2 times, leaving a remainder of 490.
Put 2 as the next digit of the answer. 
Result so far: 44173.2
If we subtract 1200 from 1690, we get 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Advancing to step 10:
600 goes into 4900 8 times with a remainder of 100.
The next digit of our result is 8. 
Result so far: 44173.28
Deduct 4800 from 4900 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

On to step 11:
600 goes into 1000 1 times with a remainder of 400.
Record the quotient 1 as the next digit in the result. 
Result so far: 44173.281
Subtracting 600 from 1000 leaves us with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Advancing to step 12:
When dividing 4000 by 600, we get 6 with a remainder of 400.
Write down 6 as next digit of the result. 
Result so far: 44173.2816
If we take 3600 away from 4000, we end up with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Let's proceed to step 13:
600 can be fit into 4000 6 times, resulting in a remainder of 400.
Put 6 as the next digit of the answer. 
Result so far: 44173.28166
Deduct 3600 from 4000 and we're left with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

The quotient of the division is 44173.28166, and the remainder is 0.0004.
