We're dividing 99125637 by 268 
The aim is to understand the frequency of 268 in 99125637.

Step 1:
The number 268 fits into 9 0 times, leaving a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 268

Advancing to step 2:
If we divide 99 by 268, we get 0 and 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.
Grab the next digit (1) from the dividend, add it to 99, then carry on: 991 / 268

Moving on to step 3:
268 can be fit into 991 3 times, resulting in a remainder of 187.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 804 away from 991, we end up with 187.
Grab the next digit (2) from the dividend, add it to 187, then carry on: 1872 / 268

On to step 4:
The number 268 fits into 1872 6 times, leaving a remainder of 264.
Record the quotient 6 as the next digit in the result. 
Result so far: 36.0
Deduct 1608 from 1872 and we're left with 264.
Append the next digit (5) from the dividend to 264 and continue with: 2645 / 268

Going ahead to step 5:
2645 divided by 268 is 9 with a remainder of 233.
Record the quotient 9 as the next digit in the result. 
Result so far: 369.0
The remainder is 233 after subtracting 2412 from 2645.
Grab the next digit (6) from the dividend, add it to 233, then carry on: 2336 / 268

Going ahead to step 6:
268 can be fit into 2336 8 times, resulting in a remainder of 192.
Record the quotient 8 as the next digit in the result. 
Result so far: 3698.0
If we subtract 2144 from 2336, we get 192.
Fetch the next digit (3) from the dividend, attach it to 192 and continue: 1923 / 268

On to step 7:
When dividing 1923 by 268, we get 7 with a remainder of 47.
Write down 7 as next digit of the result. 
Result so far: 36987.0
Deduct 1876 from 1923 and we're left with 47.
Take the next digit (7) from the dividend and append it to 47, then repeat: 477 / 268

Step 8:
If we divide 477 by 268, we get 1 and a remainder of 209.
The next digit of our result is 1. 
Result so far: 369871.0
Deduct 268 from 477 and we're left with 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

Let's proceed to step 9:
If we divide 2090 by 268, we get 7 and a remainder of 214.
Use 7 as the next digit of our solution. 
Result so far: 369871.7
Subtract 1876 from 2090 to get 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Moving on to step 10:
268 can be fit into 2140 7 times, resulting in a remainder of 264.
Write down 7 as next digit of the result. 
Result so far: 369871.77
The remainder is 264 after subtracting 1876 from 2140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

The quotient of the division is 369871.77, and the remainder is 0.264.
