Let's divide 325021 by 86
The aim is to understand the frequency of 86 in 325021.

On to step 1:
3 divided by 86 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Take the next digit (2) from the dividend and append it to 3, then repeat: 32 / 86

Going ahead to step 2:
32 divided by 86 is 0 with a remainder of 32.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 32 to get 32.
Include the next digit (5) from the dividend after 32, then repeat: 325 / 86

Let's proceed to step 3:
86 can be fit into 325 3 times, resulting in a remainder of 67.
The next digit of our result is 3. 
Result so far: 3.0
Subtract 258 from 325 to get 67.
Include the next digit (0) from the dividend after 67, then repeat: 670 / 86

Let's proceed to step 4:
86 goes into 670 7 times with a remainder of 68.
Put 7 as the next digit of the answer. 
Result so far: 37.0
The remainder is 68 after subtracting 602 from 670.
Grab the next digit (2) from the dividend, add it to 68, then carry on: 682 / 86

On to step 5:
682 divided by 86 is 7 with a remainder of 80.
Use 7 as the next digit of our solution. 
Result so far: 377.0
If we take 602 away from 682, we end up with 80.
Fetch the next digit (1) from the dividend, attach it to 80 and continue: 801 / 86

Advancing to step 6:
801 divided by 86 is 9 with a remainder of 27.
Put 9 as the next digit of the answer. 
Result so far: 3779.0
If we take 774 away from 801, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 7:
When dividing 270 by 86, we get 3 with a remainder of 12.
Use 3 as the next digit of our solution. 
Result so far: 3779.3
Subtract 258 from 270 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 8:
120 divided by 86 is 1 with a remainder of 34.
Use 1 as the next digit of our solution. 
Result so far: 3779.31
If we subtract 86 from 120, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 9:
86 goes into 340 3 times with a remainder of 82.
The number 3 becomes the next digit in our result. 
Result so far: 3779.313
Subtract 258 from 340 to get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Let's proceed to step 10:
The number 86 fits into 820 9 times, leaving a remainder of 46.
Record the quotient 9 as the next digit in the result. 
Result so far: 3779.3139
If we subtract 774 from 820, we get 46.
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 11:
86 goes into 460 5 times with a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 3779.31395
Subtracting 430 from 460 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 12:
If we divide 300 by 86, we get 3 and a remainder of 42.
Write down 3 as next digit of the result. 
Result so far: 3779.313953
Deduct 258 from 300 and we're left 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.

Moving on to step 13:
86 can be fit into 420 4 times, resulting in a remainder of 76.
Write down 4 as next digit of the result. 
Result so far: 3779.3139534
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.

On to step 14:
When dividing 760 by 86, we get 8 with a remainder of 72.
Record the quotient 8 as the next digit in the result. 
Result so far: 3779.31395348
If we subtract 688 from 760, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Our division results in 3779.31395348 with a remaining 7.2e-08.
