Let's divide 13540412 by 86
The aim is to understand the frequency of 86 in 13540412.

Advancing to step 1:
The number 86 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 86

Moving on to step 2:
If we divide 13 by 86, we get 0 and a remainder of 13.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 13, we end up with 13.
Grab the next digit (5) from the dividend, add it to 13, then carry on: 135 / 86

Step 3:
135 divided by 86 is 1 with a remainder of 49.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 86 from 135 leaves us with 49.
Bring next digit (4) of the dividend behind the 49 and repeat the process: 494 / 86

Advancing to step 4:
The number 86 fits into 494 5 times, leaving a remainder of 64.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Deduct 430 from 494 and we're left with 64.
Grab the next digit (0) from the dividend, add it to 64, then carry on: 640 / 86

Advancing to step 5:
640 divided by 86 is 7 with a remainder of 38.
Use 7 as the next digit of our solution. 
Result so far: 157.0
Subtract 602 from 640 to get 38.
Take the next digit (4) from the dividend and append it to 38, then repeat: 384 / 86

Moving on to step 6:
If we divide 384 by 86, we get 4 and a remainder of 40.
The next digit of our result is 4. 
Result so far: 1574.0
Deduct 344 from 384 and we're left with 40.
Fetch the next digit (1) from the dividend, attach it to 40 and continue: 401 / 86

Going ahead to step 7:
The number 86 fits into 401 4 times, leaving a remainder of 57.
Write down 4 as next digit of the result. 
Result so far: 15744.0
If we take 344 away from 401, we end up with 57.
Include the next digit (2) from the dividend after 57, then repeat: 572 / 86

Going ahead to step 8:
86 goes into 572 6 times with a remainder of 56.
Write down 6 as next digit of the result. 
Result so far: 157446.0
Subtracting 516 from 572 leaves us 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.

Going ahead to step 9:
The number 86 fits into 560 6 times, leaving a remainder of 44.
The next digit of our result is 6. 
Result so far: 157446.6
If we subtract 516 from 560, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 10:
86 can be fit into 440 5 times, resulting in a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 157446.65
If we subtract 430 from 440, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 11:
The number 86 fits into 100 1 times, leaving a remainder of 14.
Write down 1 as next digit of the result. 
Result so far: 157446.651
If we take 86 away from 100, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 12:
140 divided by 86 is 1 with a remainder of 54.
Use 1 as the next digit of our solution. 
Result so far: 157446.6511
Subtracting 86 from 140 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

After the division, we end up with 157446.6511 and a remainder of 0.00054.
