Let's divide 99750445 by 600
The aim is to understand the frequency of 600 in 99750445.

Let's proceed to step 1:
When dividing 9 by 600, we get 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Take the next digit (9) from the dividend and append it to 9, then repeat: 99 / 600

Moving on to step 2:
When dividing 99 by 600, we get 0 with a remainder of 99.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 99 and we're left with 99.
Bring next digit (7) of the dividend behind the 99 and repeat the process: 997 / 600

Advancing to step 3:
997 divided by 600 is 1 with a remainder of 397.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 600 from 997 leaves us with 397.
Append the next digit (5) from the dividend to 397 and continue with: 3975 / 600

Step 4:
When dividing 3975 by 600, we get 6 with a remainder of 375.
Use 6 as the next digit of our solution. 
Result so far: 16.0
If we take 3600 away from 3975, we end up with 375.
Fetch the next digit (0) from the dividend, attach it to 375 and continue: 3750 / 600

Advancing to step 5:
The number 600 fits into 3750 6 times, leaving a remainder of 150.
Write down 6 as next digit of the result. 
Result so far: 166.0
If we subtract 3600 from 3750, we get 150.
Take the next digit (4) from the dividend and append it to 150, then repeat: 1504 / 600

Advancing to step 6:
600 goes into 1504 2 times with a remainder of 304.
Write down 2 as next digit of the result. 
Result so far: 1662.0
If we subtract 1200 from 1504, we get 304.
Take the next digit (4) from the dividend and append it to 304, then repeat: 3044 / 600

Going ahead to step 7:
3044 divided by 600 is 5 with a remainder of 44.
The number 5 becomes the next digit in our result. 
Result so far: 16625.0
The remainder is 44 after subtracting 3000 from 3044.
Bring next digit (5) of the dividend behind the 44 and repeat the process: 445 / 600

Moving on to step 8:
If we divide 445 by 600, we get 0 and a remainder of 445.
Write down 0 as next digit of the result. 
Result so far: 166250.0
If we subtract 0 from 445, we get 445.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4450, and continue the process.

Moving on to step 9:
600 can be fit into 4450 7 times, resulting in a remainder of 250.
Use 7 as the next digit of our solution. 
Result so far: 166250.7
Deduct 4200 from 4450 and we're left with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Moving on to step 10:
600 goes into 2500 4 times with a remainder of 100.
Record the quotient 4 as the next digit in the result. 
Result so far: 166250.74
The remainder is 100 after subtracting 2400 from 2500.
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:
If we divide 1000 by 600, we get 1 and a remainder of 400.
Put 1 as the next digit of the answer. 
Result so far: 166250.741
If we take 600 away from 1000, 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 12:
If we divide 4000 by 600, we get 6 and a remainder of 400.
Put 6 as the next digit of the answer. 
Result so far: 166250.7416
If we subtract 3600 from 4000, we get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Going ahead to step 13:
600 can be fit into 4000 6 times, resulting in a remainder of 400.
Write down 6 as next digit of the result. 
Result so far: 166250.74166
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.

After the division, we end up with 166250.74166 and a remainder of 0.0004.
