485405 ÷ 86 
The aim is to understand the frequency of 86 in 485405.

Moving on to step 1:
86 can be fit into 4 0 times, resulting in a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Grab the next digit (8) from the dividend, add it to 4, then carry on: 48 / 86

Advancing to step 2:
86 goes into 48 0 times with a remainder of 48.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 48 and we're left with 48.
Bring next digit (5) of the dividend behind the 48 and repeat the process: 485 / 86

Moving on to step 3:
485 divided by 86 is 5 with a remainder of 55.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtract 430 from 485 to get 55.
Bring next digit (4) of the dividend behind the 55 and repeat the process: 554 / 86

Advancing to step 4:
If we divide 554 by 86, we get 6 and a remainder of 38.
The number 6 becomes the next digit in our result. 
Result so far: 56.0
The remainder is 38 after subtracting 516 from 554.
Bring next digit (0) of the dividend behind the 38 and repeat the process: 380 / 86

Step 5:
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: 564.0
If we subtract 344 from 380, we get 36.
Fetch the next digit (5) from the dividend, attach it to 36 and continue: 365 / 86

Advancing to step 6:
If we divide 365 by 86, we get 4 and a remainder of 21.
Put 4 as the next digit of the answer. 
Result so far: 5644.0
Deduct 344 from 365 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 7:
When dividing 210 by 86, we get 2 with a remainder of 38.
Use 2 as the next digit of our solution. 
Result so far: 5644.2
Subtract 172 from 210 to get 38.
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 8:
86 goes into 380 4 times with a remainder of 36.
Record the quotient 4 as the next digit in the result. 
Result so far: 5644.24
If we subtract 344 from 380, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 9:
360 divided by 86 is 4 with a remainder of 16.
The next digit of our result is 4. 
Result so far: 5644.244
If we subtract 344 from 360, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Our division results in 5644.244 with a remaining 0.0016.
