526161 ÷ 99 
The aim is to understand the frequency of 99 in 526161.

Going ahead to step 1:
99 can be fit into 5 0 times, resulting in a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Bring next digit (2) of the dividend behind the 5 and repeat the process: 52 / 99

On to step 2:
99 can be fit into 52 0 times, resulting in a remainder of 52.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 52, we get 52.
Fetch the next digit (6) from the dividend, attach it to 52 and continue: 526 / 99

Moving on to step 3:
99 can be fit into 526 5 times, resulting in a remainder of 31.
The next digit of our result is 5. 
Result so far: 5.0
Deduct 495 from 526 and we're left with 31.
Grab the next digit (1) from the dividend, add it to 31, then carry on: 311 / 99

Going ahead to step 4:
99 goes into 311 3 times with a remainder of 14.
Record the quotient 3 as the next digit in the result. 
Result so far: 53.0
Deduct 297 from 311 and we're left with 14.
Include the next digit (6) from the dividend after 14, then repeat: 146 / 99

On to step 5:
146 divided by 99 is 1 with a remainder of 47.
Record the quotient 1 as the next digit in the result. 
Result so far: 531.0
Deduct 99 from 146 and we're left with 47.
Fetch the next digit (1) from the dividend, attach it to 47 and continue: 471 / 99

Going ahead to step 6:
471 divided by 99 is 4 with a remainder of 75.
Record the quotient 4 as the next digit in the result. 
Result so far: 5314.0
Subtract 396 from 471 to get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Step 7:
99 goes into 750 7 times with a remainder of 57.
Write down 7 as next digit of the result. 
Result so far: 5314.7
Subtracting 693 from 750 leaves us with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Going ahead to step 8:
570 divided by 99 is 5 with a remainder of 75.
Write down 5 as next digit of the result. 
Result so far: 5314.75
If we subtract 495 from 570, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Let's proceed to step 9:
If we divide 750 by 99, we get 7 and a remainder of 57.
The number 7 becomes the next digit in our result. 
Result so far: 5314.757
Deduct 693 from 750 and we're left with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Step 10:
570 divided by 99 is 5 with a remainder of 75.
Put 5 as the next digit of the answer. 
Result so far: 5314.7575
If we take 495 away from 570, we end up with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Let's proceed to step 11:
99 goes into 750 7 times with a remainder of 57.
Put 7 as the next digit of the answer. 
Result so far: 5314.75757
Subtract 693 from 750 to get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Advancing to step 12:
570 divided by 99 is 5 with a remainder of 75.
The number 5 becomes the next digit in our result. 
Result so far: 5314.757575
Subtracting 495 from 570 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Let's proceed to step 13:
750 divided by 99 is 7 with a remainder of 57.
The number 7 becomes the next digit in our result. 
Result so far: 5314.7575757
Deduct 693 from 750 and we're left with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Let's proceed to step 14:
99 can be fit into 570 5 times, resulting in a remainder of 75.
Put 5 as the next digit of the answer. 
Result so far: 5314.75757575
Deduct 495 from 570 and we're left with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

After the division, we end up with 5314.75757575 and a remainder of 7.5e-08.
