941691 ÷ 86 
The aim is to understand the frequency of 86 in 941691.

Step 1:
When dividing 9 by 86, we get 0 with a remainder of 9.
Write down 0 as next digit of the 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

Going ahead 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
Subtracting 86 from 94 leaves us with 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 86

Advancing to step 3:
If we divide 81 by 86, we get 0 and a remainder of 81.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
If we take 0 away from 81, we end up with 81.
Take the next digit (6) from the dividend and append it to 81, then repeat: 816 / 86

Going ahead to step 4:
The number 86 fits into 816 9 times, leaving a remainder of 42.
Record the quotient 9 as the next digit in the result. 
Result so far: 109.0
Subtract 774 from 816 to get 42.
Grab the next digit (9) from the dividend, add it to 42, then carry on: 429 / 86

On to step 5:
The number 86 fits into 429 4 times, leaving a remainder of 85.
The number 4 becomes the next digit in our result. 
Result so far: 1094.0
The remainder is 85 after subtracting 344 from 429.
Append the next digit (1) from the dividend to 85 and continue with: 851 / 86

On to step 6:
If we divide 851 by 86, we get 9 and a remainder of 77.
The number 9 becomes the next digit in our result. 
Result so far: 10949.0
If we take 774 away from 851, we end up with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Advancing to step 7:
When dividing 770 by 86, we get 8 with a remainder of 82.
Record the quotient 8 as the next digit in the result. 
Result so far: 10949.8
Deduct 688 from 770 and we're left with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Moving on to step 8:
If we divide 820 by 86, we get 9 and a remainder of 46.
The next digit of our result is 9. 
Result so far: 10949.89
If we subtract 774 from 820, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 9:
The number 86 fits into 460 5 times, leaving a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 10949.895
Subtract 430 from 460 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 10:
300 divided by 86 is 3 with a remainder of 42.
The number 3 becomes the next digit in our result. 
Result so far: 10949.8953
Subtracting 258 from 300 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 11:
420 divided by 86 is 4 with a remainder of 76.
The number 4 becomes the next digit in our result. 
Result so far: 10949.89534
Deduct 344 from 420 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Moving on to step 12:
The number 86 fits into 760 8 times, leaving a remainder of 72.
The number 8 becomes the next digit in our result. 
Result so far: 10949.895348
Subtract 688 from 760 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 13:
720 divided by 86 is 8 with a remainder of 32.
The next digit of our result is 8. 
Result so far: 10949.8953488
If we subtract 688 from 720, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The quotient of the division is 10949.8953488, and the remainder is 3.2e-07.
