91411881 divided by 755 
The aim is to understand the frequency of 755 in 91411881.

Going ahead to step 1:
755 goes into 9 0 times with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 755

Let's proceed to step 2:
The number 755 fits into 91 0 times, leaving a remainder of 91.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 91 and we're left with 91.
Take the next digit (4) from the dividend and append it to 91, then repeat: 914 / 755

Going ahead to step 3:
When dividing 914 by 755, we get 1 with a remainder of 159.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 755 from 914 to get 159.
Append the next digit (1) from the dividend to 159 and continue with: 1591 / 755

Step 4:
If we divide 1591 by 755, we get 2 and a remainder of 81.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
If we subtract 1510 from 1591, we get 81.
Grab the next digit (1) from the dividend, add it to 81, then carry on: 811 / 755

On to step 5:
755 can be fit into 811 1 times, resulting in a remainder of 56.
Put 1 as the next digit of the answer. 
Result so far: 121.0
Subtract 755 from 811 to get 56.
Grab the next digit (8) from the dividend, add it to 56, then carry on: 568 / 755

On to step 6:
When dividing 568 by 755, we get 0 with a remainder of 568.
Put 0 as the next digit of the answer. 
Result so far: 1210.0
Deduct 0 from 568 and we're left with 568.
Grab the next digit (8) from the dividend, add it to 568, then carry on: 5688 / 755

On to step 7:
When dividing 5688 by 755, we get 7 with a remainder of 403.
Use 7 as the next digit of our solution. 
Result so far: 12107.0
The remainder is 403 after subtracting 5285 from 5688.
Take the next digit (1) from the dividend and append it to 403, then repeat: 4031 / 755

Moving on to step 8:
The number 755 fits into 4031 5 times, leaving a remainder of 256.
The next digit of our result is 5. 
Result so far: 121075.0
Deduct 3775 from 4031 and we're left with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Going ahead to step 9:
2560 divided by 755 is 3 with a remainder of 295.
The next digit of our result is 3. 
Result so far: 121075.3
Subtracting 2265 from 2560 leaves us with 295.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

Going ahead to step 10:
755 can be fit into 2950 3 times, resulting in a remainder of 685.
Use 3 as the next digit of our solution. 
Result so far: 121075.33
Subtracting 2265 from 2950 leaves us with 685.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6850, and continue the process.

After the division, we end up with 121075.33 and a remainder of 0.685.
