Let's divide 155312 by 86
The aim is to understand the frequency of 86 in 155312.

Going ahead to step 1:
When dividing 1 by 86, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 86

Advancing to step 2:
86 goes into 15 0 times with a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 15 after subtracting 0 from 15.
Include the next digit (5) from the dividend after 15, then repeat: 155 / 86

Step 3:
The number 86 fits into 155 1 times, leaving a remainder of 69.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 86 from 155 leaves us with 69.
Take the next digit (3) from the dividend and append it to 69, then repeat: 693 / 86

Step 4:
If we divide 693 by 86, we get 8 and a remainder of 5.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
If we take 688 away from 693, we end up with 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 86

Advancing to step 5:
The number 86 fits into 51 0 times, leaving a remainder of 51.
Use 0 as the next digit of our solution. 
Result so far: 180.0
The remainder is 51 after subtracting 0 from 51.
Bring next digit (2) of the dividend behind the 51 and repeat the process: 512 / 86

On to step 6:
The number 86 fits into 512 5 times, leaving a remainder of 82.
Write down 5 as next digit of the result. 
Result so far: 1805.0
Subtracting 430 from 512 leaves us 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.

Step 7:
86 can be fit into 820 9 times, resulting in a remainder of 46.
The number 9 becomes the next digit in our result. 
Result so far: 1805.9
The remainder is 46 after subtracting 774 from 820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 8:
When dividing 460 by 86, we get 5 with a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 1805.95
Subtract 430 from 460 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 9:
When dividing 300 by 86, we get 3 with a remainder of 42.
Use 3 as the next digit of our solution. 
Result so far: 1805.953
Subtracting 258 from 300 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 10:
86 goes into 420 4 times with a remainder of 76.
Use 4 as the next digit of our solution. 
Result so far: 1805.9534
If we subtract 344 from 420, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 11:
86 can be fit into 760 8 times, resulting in a remainder of 72.
The number 8 becomes the next digit in our result. 
Result so far: 1805.95348
Subtracting 688 from 760 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 12:
The number 86 fits into 720 8 times, leaving a remainder of 32.
Write down 8 as next digit of the result. 
Result so far: 1805.953488
Subtract 688 from 720 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The quotient of the division is 1805.953488, and the remainder is 3.2e-06.
