408148 ÷ 86 
The aim is to understand the frequency of 86 in 408148.

Let's proceed to step 1:
86 goes into 4 0 times with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 86

Let's proceed to step 2:
86 goes into 40 0 times with a remainder of 40.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 40 to get 40.
Fetch the next digit (8) from the dividend, attach it to 40 and continue: 408 / 86

Going ahead to step 3:
86 goes into 408 4 times with a remainder of 64.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 344 from 408 and we're left with 64.
Include the next digit (1) from the dividend after 64, then repeat: 641 / 86

Going ahead to step 4:
The number 86 fits into 641 7 times, leaving a remainder of 39.
Write down 7 as next digit of the result. 
Result so far: 47.0
If we subtract 602 from 641, we get 39.
Fetch the next digit (4) from the dividend, attach it to 39 and continue: 394 / 86

Going ahead to step 5:
When dividing 394 by 86, we get 4 with a remainder of 50.
Put 4 as the next digit of the answer. 
Result so far: 474.0
Subtracting 344 from 394 leaves us with 50.
Fetch the next digit (8) from the dividend, attach it to 50 and continue: 508 / 86

Going ahead to step 6:
86 goes into 508 5 times with a remainder of 78.
Record the quotient 5 as the next digit in the result. 
Result so far: 4745.0
The remainder is 78 after subtracting 430 from 508.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

On to step 7:
If we divide 780 by 86, we get 9 and a remainder of 6.
Put 9 as the next digit of the answer. 
Result so far: 4745.9
Deduct 774 from 780 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 8:
If we divide 60 by 86, we get 0 and a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 4745.9
If we subtract 0 from 60, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 9:
If we divide 600 by 86, we get 6 and a remainder of 84.
Write down 6 as next digit of the result. 
Result so far: 4745.906
Subtracting 516 from 600 leaves us with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Let's proceed to step 10:
If we divide 840 by 86, we get 9 and a remainder of 66.
Write down 9 as next digit of the result. 
Result so far: 4745.9069
If we take 774 away from 840, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Going ahead to step 11:
660 divided by 86 is 7 with a remainder of 58.
Write down 7 as next digit of the result. 
Result so far: 4745.90697
If we take 602 away from 660, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 12:
The number 86 fits into 580 6 times, leaving a remainder of 64.
Record the quotient 6 as the next digit in the result. 
Result so far: 4745.906976
Deduct 516 from 580 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 13:
If we divide 640 by 86, we get 7 and a remainder of 38.
Put 7 as the next digit of the answer. 
Result so far: 4745.9069767
The remainder is 38 after subtracting 602 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 14:
The number 86 fits into 380 4 times, leaving a remainder of 36.
Use 4 as the next digit of our solution. 
Result so far: 4745.90697674
Deduct 344 from 380 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

After the division, we end up with 4745.90697674 and a remainder of 3.6e-08.
