We divide 603747 by 99
The aim is to understand the frequency of 99 in 603747.

Moving on to step 1:
If we divide 6 by 99, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (0) of the dividend behind the 6 and repeat the process: 60 / 99

Step 2:
When dividing 60 by 99, we get 0 with a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 60, we end up with 60.
Include the next digit (3) from the dividend after 60, then repeat: 603 / 99

On to step 3:
When dividing 603 by 99, we get 6 with a remainder of 9.
Put 6 as the next digit of the answer. 
Result so far: 6.0
If we take 594 away from 603, we end up with 9.
Bring next digit (7) of the dividend behind the 9 and repeat the process: 97 / 99

Moving on to step 4:
99 goes into 97 0 times with a remainder of 97.
Write down 0 as next digit of the result. 
Result so far: 60.0
Deduct 0 from 97 and we're left with 97.
Take the next digit (4) from the dividend and append it to 97, then repeat: 974 / 99

Let's proceed to step 5:
99 can be fit into 974 9 times, resulting in a remainder of 83.
Put 9 as the next digit of the answer. 
Result so far: 609.0
Deduct 891 from 974 and we're left with 83.
Append the next digit (7) from the dividend to 83 and continue with: 837 / 99

Let's proceed to step 6:
99 goes into 837 8 times with a remainder of 45.
The next digit of our result is 8. 
Result so far: 6098.0
Subtract 792 from 837 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 7:
When dividing 450 by 99, we get 4 with a remainder of 54.
Record the quotient 4 as the next digit in the result. 
Result so far: 6098.4
Subtract 396 from 450 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 8:
540 divided by 99 is 5 with a remainder of 45.
Write down 5 as next digit of the result. 
Result so far: 6098.45
If we take 495 away from 540, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 9:
The number 99 fits into 450 4 times, leaving a remainder of 54.
Write down 4 as next digit of the result. 
Result so far: 6098.454
If we subtract 396 from 450, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 10:
The number 99 fits into 540 5 times, leaving a remainder of 45.
Write down 5 as next digit of the result. 
Result so far: 6098.4545
If we subtract 495 from 540, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 11:
99 can be fit into 450 4 times, resulting in a remainder of 54.
The number 4 becomes the next digit in our result. 
Result so far: 6098.45454
Subtract 396 from 450 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

On to step 12:
When dividing 540 by 99, we get 5 with a remainder of 45.
Use 5 as the next digit of our solution. 
Result so far: 6098.454545
If we take 495 away from 540, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 13:
450 divided by 99 is 4 with a remainder of 54.
The next digit of our result is 4. 
Result so far: 6098.4545454
If we subtract 396 from 450, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 14:
The number 99 fits into 540 5 times, leaving a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 6098.45454545
Deduct 495 from 540 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

After the division, we end up with 6098.45454545 and a remainder of 4.5e-08.
