We're dividing 935381 by 86 
The aim is to understand the frequency of 86 in 935381.

Advancing to step 1:
9 divided by 86 is 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Grab the next digit (3) from the dividend, add it to 9, then carry on: 93 / 86

Going ahead to step 2:
If we divide 93 by 86, we get 1 and a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 86 from 93 leaves us with 7.
Fetch the next digit (5) from the dividend, attach it to 7 and continue: 75 / 86

Moving on to step 3:
If we divide 75 by 86, we get 0 and a remainder of 75.
The next digit of our result is 0. 
Result so far: 10.0
If we subtract 0 from 75, we get 75.
Bring next digit (3) of the dividend behind the 75 and repeat the process: 753 / 86

Going ahead to step 4:
The number 86 fits into 753 8 times, leaving a remainder of 65.
Put 8 as the next digit of the answer. 
Result so far: 108.0
If we take 688 away from 753, we end up with 65.
Take the next digit (8) from the dividend and append it to 65, then repeat: 658 / 86

Step 5:
86 goes into 658 7 times with a remainder of 56.
The next digit of our result is 7. 
Result so far: 1087.0
The remainder is 56 after subtracting 602 from 658.
Append the next digit (1) from the dividend to 56 and continue with: 561 / 86

On to step 6:
The number 86 fits into 561 6 times, leaving a remainder of 45.
Write down 6 as next digit of the result. 
Result so far: 10876.0
If we take 516 away from 561, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 7:
When dividing 450 by 86, we get 5 with a remainder of 20.
The next digit of our result is 5. 
Result so far: 10876.5
If we take 430 away from 450, we end up 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 8:
When dividing 200 by 86, we get 2 with a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 10876.52
If we take 172 away from 200, we end up 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.

Going ahead to step 9:
When dividing 280 by 86, we get 3 with a remainder of 22.
The number 3 becomes the next digit in our result. 
Result so far: 10876.523
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.

Let's proceed to step 10:
When dividing 220 by 86, we get 2 with a remainder of 48.
Use 2 as the next digit of our solution. 
Result so far: 10876.5232
Subtract 172 from 220 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 11:
If we divide 480 by 86, we get 5 and a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 10876.52325
If we subtract 430 from 480, we 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.

Step 12:
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: 10876.523255
Subtracting 430 from 500 leaves us with 70.
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 10876.523255 and a remainder of 7e-06.
