350076 ÷ 86 
The aim is to understand the frequency of 86 in 350076.

Step 1:
When dividing 3 by 86, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Grab the next digit (5) from the dividend, add it to 3, then carry on: 35 / 86

Going ahead to step 2:
If we divide 35 by 86, we get 0 and a remainder of 35.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 35 and we're left with 35.
Bring next digit (0) of the dividend behind the 35 and repeat the process: 350 / 86

On to step 3:
86 can be fit into 350 4 times, resulting in a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtracting 344 from 350 leaves us with 6.
Bring next digit (0) of the dividend behind the 6 and repeat the process: 60 / 86

On to step 4:
60 divided by 86 is 0 with a remainder of 60.
The next digit of our result is 0. 
Result so far: 40.0
If we take 0 away from 60, we end up with 60.
Include the next digit (7) from the dividend after 60, then repeat: 607 / 86

On to step 5:
86 can be fit into 607 7 times, resulting in a remainder of 5.
Record the quotient 7 as the next digit in the result. 
Result so far: 407.0
Subtracting 602 from 607 leaves us with 5.
Grab the next digit (6) from the dividend, add it to 5, then carry on: 56 / 86

Let's proceed to step 6:
If we divide 56 by 86, we get 0 and a remainder of 56.
The number 0 becomes the next digit in our result. 
Result so far: 4070.0
If we take 0 away from 56, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 7:
86 goes into 560 6 times with a remainder of 44.
Record the quotient 6 as the next digit in the result. 
Result so far: 4070.6
Subtracting 516 from 560 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 8:
86 goes into 440 5 times with a remainder of 10.
The next digit of our result is 5. 
Result so far: 4070.65
Deduct 430 from 440 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 9:
If we divide 100 by 86, we get 1 and a remainder of 14.
The next digit of our result is 1. 
Result so far: 4070.651
The remainder is 14 after subtracting 86 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 10:
If we divide 140 by 86, we get 1 and a remainder of 54.
The number 1 becomes the next digit in our result. 
Result so far: 4070.6511
Deduct 86 from 140 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

After the division, we end up with 4070.6511 and a remainder of 0.00054.
