941635 ÷ 86 
The aim is to understand the frequency of 86 in 941635.

Going ahead 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
Subtract 0 from 9 to get 9.
Append the next digit (4) from the dividend to 9 and continue with: 94 / 86

Advancing to step 2:
86 goes into 94 1 times with a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 8 after subtracting 86 from 94.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 86

Going ahead to step 3:
81 divided by 86 is 0 with a remainder of 81.
The next digit of our result is 0. 
Result so far: 10.0
If we subtract 0 from 81, we get 81.
Fetch the next digit (6) from the dividend, attach it to 81 and continue: 816 / 86

On to step 4:
When dividing 816 by 86, we get 9 with a remainder of 42.
The next digit of our result is 9. 
Result so far: 109.0
The remainder is 42 after subtracting 774 from 816.
Bring next digit (3) of the dividend behind the 42 and repeat the process: 423 / 86

Step 5:
423 divided by 86 is 4 with a remainder of 79.
The number 4 becomes the next digit in our result. 
Result so far: 1094.0
If we subtract 344 from 423, we get 79.
Include the next digit (5) from the dividend after 79, then repeat: 795 / 86

Moving on to step 6:
When dividing 795 by 86, we get 9 with a remainder of 21.
The next digit of our result is 9. 
Result so far: 10949.0
If we take 774 away from 795, we end up 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.

Going ahead to step 7:
86 goes into 210 2 times with a remainder of 38.
The number 2 becomes the next digit in our result. 
Result so far: 10949.2
Deduct 172 from 210 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 8:
If we divide 380 by 86, we get 4 and a remainder of 36.
The next digit of our result is 4. 
Result so far: 10949.24
The remainder is 36 after subtracting 344 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 9:
86 can be fit into 360 4 times, resulting in a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 10949.244
Subtract 344 from 360 to 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.

The final result is 10949.244 with a remainder of 0.0016.
