We're dividing 423484 by 86 
The aim is to understand the frequency of 86 in 423484.

Advancing to step 1:
86 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 86

On to step 2:
When dividing 42 by 86, we get 0 with a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 42, we end up with 42.
Include the next digit (3) from the dividend after 42, then repeat: 423 / 86

Step 3:
When dividing 423 by 86, we get 4 with a remainder of 79.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtract 344 from 423 to get 79.
Include the next digit (4) from the dividend after 79, then repeat: 794 / 86

On to step 4:
794 divided by 86 is 9 with a remainder of 20.
The number 9 becomes the next digit in our result. 
Result so far: 49.0
Subtract 774 from 794 to get 20.
Take the next digit (8) from the dividend and append it to 20, then repeat: 208 / 86

Step 5:
86 goes into 208 2 times with a remainder of 36.
The number 2 becomes the next digit in our result. 
Result so far: 492.0
If we take 172 away from 208, we end up with 36.
Include the next digit (4) from the dividend after 36, then repeat: 364 / 86

Let's proceed to step 6:
364 divided by 86 is 4 with a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 4924.0
If we subtract 344 from 364, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 7:
200 divided by 86 is 2 with a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 4924.2
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.

Step 8:
86 can be fit into 280 3 times, resulting in a remainder of 22.
Put 3 as the next digit of the answer. 
Result so far: 4924.23
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.

Advancing to step 9:
When dividing 220 by 86, we get 2 with a remainder of 48.
Write down 2 as next digit of the result. 
Result so far: 4924.232
Deduct 172 from 220 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 10:
The number 86 fits into 480 5 times, leaving a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 4924.2325
Subtract 430 from 480 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 11:
500 divided by 86 is 5 with a remainder of 70.
Record the quotient 5 as the next digit in the result. 
Result so far: 4924.23255
The remainder is 70 after subtracting 430 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

After the division, we end up with 4924.23255 and a remainder of 7e-05.
