989668 ÷ 86 
The aim is to understand the frequency of 86 in 989668.

Moving on to step 1:
86 goes into 9 0 times with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Take the next digit (8) from the dividend and append it to 9, then repeat: 98 / 86

Going ahead to step 2:
86 goes into 98 1 times with a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 86 from 98 and we're left with 12.
Bring next digit (9) of the dividend behind the 12 and repeat the process: 129 / 86

Let's proceed to step 3:
129 divided by 86 is 1 with a remainder of 43.
The next digit of our result is 1. 
Result so far: 11.0
Subtracting 86 from 129 leaves us with 43.
Grab the next digit (6) from the dividend, add it to 43, then carry on: 436 / 86

Step 4:
If we divide 436 by 86, we get 5 and a remainder of 6.
Write down 5 as next digit of the result. 
Result so far: 115.0
If we subtract 430 from 436, we get 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 86

Advancing to step 5:
If we divide 66 by 86, we get 0 and a remainder of 66.
The number 0 becomes the next digit in our result. 
Result so far: 1150.0
Subtracting 0 from 66 leaves us with 66.
Grab the next digit (8) from the dividend, add it to 66, then carry on: 668 / 86

Let's proceed to step 6:
668 divided by 86 is 7 with a remainder of 66.
The number 7 becomes the next digit in our result. 
Result so far: 11507.0
Subtract 602 from 668 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Advancing to step 7:
86 goes into 660 7 times with a remainder of 58.
Write down 7 as next digit of the result. 
Result so far: 11507.7
If we subtract 602 from 660, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 8:
The number 86 fits into 580 6 times, leaving a remainder of 64.
Use 6 as the next digit of our solution. 
Result so far: 11507.76
Subtract 516 from 580 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 9:
640 divided by 86 is 7 with a remainder of 38.
The number 7 becomes the next digit in our result. 
Result so far: 11507.767
Subtract 602 from 640 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 10:
If we divide 380 by 86, we get 4 and a remainder of 36.
Use 4 as the next digit of our solution. 
Result so far: 11507.7674
Subtracting 344 from 380 leaves us with 36.
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 11:
The number 86 fits into 360 4 times, leaving a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 11507.76744
If we subtract 344 from 360, we 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 quotient of the division is 11507.76744, and the remainder is 1.6e-05.
