91009109 divided by 232 
The aim is to understand the frequency of 232 in 91009109.

On to step 1:
232 goes into 9 0 times with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 232

On to step 2:
The number 232 fits into 91 0 times, leaving a remainder of 91.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 91, we end up with 91.
Take the next digit (0) from the dividend and append it to 91, then repeat: 910 / 232

Moving on to step 3:
910 divided by 232 is 3 with a remainder of 214.
The next digit of our result is 3. 
Result so far: 3.0
Subtracting 696 from 910 leaves us with 214.
Append the next digit (0) from the dividend to 214 and continue with: 2140 / 232

On to step 4:
When dividing 2140 by 232, we get 9 with a remainder of 52.
The number 9 becomes the next digit in our result. 
Result so far: 39.0
If we take 2088 away from 2140, we end up with 52.
Grab the next digit (9) from the dividend, add it to 52, then carry on: 529 / 232

Step 5:
529 divided by 232 is 2 with a remainder of 65.
Put 2 as the next digit of the answer. 
Result so far: 392.0
If we subtract 464 from 529, we get 65.
Grab the next digit (1) from the dividend, add it to 65, then carry on: 651 / 232

Going ahead to step 6:
651 divided by 232 is 2 with a remainder of 187.
Use 2 as the next digit of our solution. 
Result so far: 3922.0
Subtract 464 from 651 to get 187.
Bring next digit (0) of the dividend behind the 187 and repeat the process: 1870 / 232

Let's proceed to step 7:
232 goes into 1870 8 times with a remainder of 14.
Use 8 as the next digit of our solution. 
Result so far: 39228.0
If we take 1856 away from 1870, we end up with 14.
Grab the next digit (9) from the dividend, add it to 14, then carry on: 149 / 232

On to step 8:
232 can be fit into 149 0 times, resulting in a remainder of 149.
Write down 0 as next digit of the result. 
Result so far: 392280.0
Deduct 0 from 149 and we're left with 149.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

Let's proceed to step 9:
232 can be fit into 1490 6 times, resulting in a remainder of 98.
Write down 6 as next digit of the result. 
Result so far: 392280.6
Subtract 1392 from 1490 to get 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Going ahead to step 10:
The number 232 fits into 980 4 times, leaving a remainder of 52.
Write down 4 as next digit of the result. 
Result so far: 392280.64
Subtract 928 from 980 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 11:
The number 232 fits into 520 2 times, leaving a remainder of 56.
Put 2 as the next digit of the answer. 
Result so far: 392280.642
Deduct 464 from 520 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 12:
232 can be fit into 560 2 times, resulting in a remainder of 96.
The next digit of our result is 2. 
Result so far: 392280.6422
Subtracting 464 from 560 leaves us with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

The quotient of the division is 392280.6422, and the remainder is 0.00096.
