441603 ÷ 99 
The aim is to understand the frequency of 99 in 441603.

Moving on to step 1:
99 goes into 4 0 times with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (4) from the dividend, attach it to 4 and continue: 44 / 99

Advancing to step 2:
99 goes into 44 0 times with a remainder of 44.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 44 after subtracting 0 from 44.
Grab the next digit (1) from the dividend, add it to 44, then carry on: 441 / 99

Advancing to step 3:
If we divide 441 by 99, we get 4 and a remainder of 45.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 396 from 441 and we're left with 45.
Include the next digit (6) from the dividend after 45, then repeat: 456 / 99

Moving on to step 4:
If we divide 456 by 99, we get 4 and a remainder of 60.
Record the quotient 4 as the next digit in the result. 
Result so far: 44.0
Subtracting 396 from 456 leaves us with 60.
Bring next digit (0) of the dividend behind the 60 and repeat the process: 600 / 99

Step 5:
When dividing 600 by 99, we get 6 with a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 446.0
If we take 594 away from 600, we end up with 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 99

Let's proceed to step 6:
99 goes into 63 0 times with a remainder of 63.
The number 0 becomes the next digit in our result. 
Result so far: 4460.0
Subtracting 0 from 63 leaves us with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

On to step 7:
The number 99 fits into 630 6 times, leaving a remainder of 36.
Use 6 as the next digit of our solution. 
Result so far: 4460.6
Subtract 594 from 630 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 8:
99 goes into 360 3 times with a remainder of 63.
The next digit of our result is 3. 
Result so far: 4460.63
The remainder is 63 after subtracting 297 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Advancing to step 9:
The number 99 fits into 630 6 times, leaving a remainder of 36.
Write down 6 as next digit of the result. 
Result so far: 4460.636
If we subtract 594 from 630, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 10:
99 goes into 360 3 times with a remainder of 63.
The number 3 becomes the next digit in our result. 
Result so far: 4460.6363
Deduct 297 from 360 and we're left with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Advancing to step 11:
When dividing 630 by 99, we get 6 with a remainder of 36.
The number 6 becomes the next digit in our result. 
Result so far: 4460.63636
Subtracting 594 from 630 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 12:
When dividing 360 by 99, we get 3 with a remainder of 63.
Record the quotient 3 as the next digit in the result. 
Result so far: 4460.636363
Subtracting 297 from 360 leaves us with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Advancing to step 13:
99 goes into 630 6 times with a remainder of 36.
The number 6 becomes the next digit in our result. 
Result so far: 4460.6363636
Subtract 594 from 630 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 14:
The number 99 fits into 360 3 times, leaving a remainder of 63.
The next digit of our result is 3. 
Result so far: 4460.63636363
Deduct 297 from 360 and we're left with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

The final result is 4460.63636363 with a remainder of 6.3e-08.
