385772 ÷ 86 
The aim is to understand the frequency of 86 in 385772.

On to step 1:
If we divide 3 by 86, we get 0 and a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 86

Let's proceed to step 2:
When dividing 38 by 86, we get 0 with a remainder of 38.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 38 and we're left with 38.
Bring next digit (5) of the dividend behind the 38 and repeat the process: 385 / 86

Going ahead to step 3:
86 goes into 385 4 times with a remainder of 41.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtracting 344 from 385 leaves us with 41.
Append the next digit (7) from the dividend to 41 and continue with: 417 / 86

Moving on to step 4:
86 goes into 417 4 times with a remainder of 73.
Record the quotient 4 as the next digit in the result. 
Result so far: 44.0
If we subtract 344 from 417, we get 73.
Take the next digit (7) from the dividend and append it to 73, then repeat: 737 / 86

Let's proceed to step 5:
If we divide 737 by 86, we get 8 and a remainder of 49.
The number 8 becomes the next digit in our result. 
Result so far: 448.0
Subtracting 688 from 737 leaves us with 49.
Append the next digit (2) from the dividend to 49 and continue with: 492 / 86

Step 6:
86 can be fit into 492 5 times, resulting in a remainder of 62.
Write down 5 as next digit of the result. 
Result so far: 4485.0
Deduct 430 from 492 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 7:
The number 86 fits into 620 7 times, leaving a remainder of 18.
The number 7 becomes the next digit in our result. 
Result so far: 4485.7
If we subtract 602 from 620, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 8:
180 divided by 86 is 2 with a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 4485.72
Deduct 172 from 180 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 9:
The number 86 fits into 80 0 times, leaving a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 4485.72
Subtracting 0 from 80 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 10:
86 goes into 800 9 times with a remainder of 26.
Use 9 as the next digit of our solution. 
Result so far: 4485.7209
If we take 774 away from 800, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 11:
If we divide 260 by 86, we get 3 and a remainder of 2.
The next digit of our result is 3. 
Result so far: 4485.72093
Subtracting 258 from 260 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 12:
86 goes into 20 0 times with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 4485.72093
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 13:
If we divide 200 by 86, we get 2 and a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 4485.7209302
Deduct 172 from 200 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 14:
The number 86 fits into 280 3 times, leaving a remainder of 22.
Put 3 as the next digit of the answer. 
Result so far: 4485.72093023
Deduct 258 from 280 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

The quotient of the division is 4485.72093023, and the remainder is 2.2e-08.
