Let's divide 81086231 by 655
The aim is to understand the frequency of 655 in 81086231.

Moving on to step 1:
8 divided by 655 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 655

Going ahead to step 2:
The number 655 fits into 81 0 times, leaving a remainder of 81.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 81, we end up with 81.
Fetch the next digit (0) from the dividend, attach it to 81 and continue: 810 / 655

On to step 3:
655 can be fit into 810 1 times, resulting in a remainder of 155.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 155 after subtracting 655 from 810.
Include the next digit (8) from the dividend after 155, then repeat: 1558 / 655

Let's proceed to step 4:
If we divide 1558 by 655, we get 2 and a remainder of 248.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Subtracting 1310 from 1558 leaves us with 248.
Grab the next digit (6) from the dividend, add it to 248, then carry on: 2486 / 655

On to step 5:
When dividing 2486 by 655, we get 3 with a remainder of 521.
Use 3 as the next digit of our solution. 
Result so far: 123.0
If we subtract 1965 from 2486, we get 521.
Append the next digit (2) from the dividend to 521 and continue with: 5212 / 655

Going ahead to step 6:
655 can be fit into 5212 7 times, resulting in a remainder of 627.
The next digit of our result is 7. 
Result so far: 1237.0
Subtracting 4585 from 5212 leaves us with 627.
Append the next digit (3) from the dividend to 627 and continue with: 6273 / 655

Step 7:
655 can be fit into 6273 9 times, resulting in a remainder of 378.
Put 9 as the next digit of the answer. 
Result so far: 12379.0
The remainder is 378 after subtracting 5895 from 6273.
Grab the next digit (1) from the dividend, add it to 378, then carry on: 3781 / 655

Moving on to step 8:
3781 divided by 655 is 5 with a remainder of 506.
The number 5 becomes the next digit in our result. 
Result so far: 123795.0
The remainder is 506 after subtracting 3275 from 3781.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5060, and continue the process.

Step 9:
655 can be fit into 5060 7 times, resulting in a remainder of 475.
Write down 7 as next digit of the result. 
Result so far: 123795.7
Subtracting 4585 from 5060 leaves us with 475.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4750, and continue the process.

Moving on to step 10:
The number 655 fits into 4750 7 times, leaving a remainder of 165.
The number 7 becomes the next digit in our result. 
Result so far: 123795.77
If we subtract 4585 from 4750, we get 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

The quotient of the division is 123795.77, and the remainder is 0.165.
