Let's divide 99912371 by 266
The aim is to understand the frequency of 266 in 99912371.

Moving on to step 1:
When dividing 9 by 266, we get 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 266

Going ahead to step 2:
When dividing 99 by 266, 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.
Include the next digit (9) from the dividend after 99, then repeat: 999 / 266

Moving on to step 3:
999 divided by 266 is 3 with a remainder of 201.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we subtract 798 from 999, we get 201.
Include the next digit (1) from the dividend after 201, then repeat: 2011 / 266

On to step 4:
266 goes into 2011 7 times with a remainder of 149.
Write down 7 as next digit of the result. 
Result so far: 37.0
The remainder is 149 after subtracting 1862 from 2011.
Take the next digit (2) from the dividend and append it to 149, then repeat: 1492 / 266

Advancing to step 5:
266 goes into 1492 5 times with a remainder of 162.
The number 5 becomes the next digit in our result. 
Result so far: 375.0
If we take 1330 away from 1492, we end up with 162.
Grab the next digit (3) from the dividend, add it to 162, then carry on: 1623 / 266

Advancing to step 6:
266 can be fit into 1623 6 times, resulting in a remainder of 27.
The next digit of our result is 6. 
Result so far: 3756.0
Subtract 1596 from 1623 to get 27.
Append the next digit (7) from the dividend to 27 and continue with: 277 / 266

Step 7:
277 divided by 266 is 1 with a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 37561.0
If we subtract 266 from 277, we get 11.
Take the next digit (1) from the dividend and append it to 11, then repeat: 111 / 266

Step 8:
111 divided by 266 is 0 with a remainder of 111.
Use 0 as the next digit of our solution. 
Result so far: 375610.0
Deduct 0 from 111 and we're left with 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

Let's proceed to step 9:
266 goes into 1110 4 times with a remainder of 46.
Use 4 as the next digit of our solution. 
Result so far: 375610.4
If we take 1064 away from 1110, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 10:
266 can be fit into 460 1 times, resulting in a remainder of 194.
Put 1 as the next digit of the answer. 
Result so far: 375610.41
The remainder is 194 after subtracting 266 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

Advancing to step 11:
If we divide 1940 by 266, we get 7 and a remainder of 78.
Use 7 as the next digit of our solution. 
Result so far: 375610.417
Subtracting 1862 from 1940 leaves us with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

On to step 12:
266 goes into 780 2 times with a remainder of 248.
Record the quotient 2 as the next digit in the result. 
Result so far: 375610.4172
Deduct 532 from 780 and we're left with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

On to step 13:
When dividing 2480 by 266, we get 9 with a remainder of 86.
Use 9 as the next digit of our solution. 
Result so far: 375610.41729
Subtract 2394 from 2480 to get 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Step 14:
266 can be fit into 860 3 times, resulting in a remainder of 62.
Write down 3 as next digit of the result. 
Result so far: 375610.417293
If we subtract 798 from 860, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 15:
The number 266 fits into 620 2 times, leaving a remainder of 88.
The next digit of our result is 2. 
Result so far: 375610.4172932
Subtract 532 from 620 to get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Moving on to step 16:
If we divide 880 by 266, we get 3 and a remainder of 82.
Use 3 as the next digit of our solution. 
Result so far: 375610.41729323
If we take 798 away from 880, we end up with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Our division results in 375610.41729323 with a remaining 8.2e-08.
