719949 ÷ 86 
The aim is to understand the frequency of 86 in 719949.

Going ahead to step 1:
86 can be fit into 7 0 times, resulting in a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 86

Going ahead to step 2:
86 goes into 71 0 times with a remainder of 71.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 71 to get 71.
Include the next digit (9) from the dividend after 71, then repeat: 719 / 86

On to step 3:
The number 86 fits into 719 8 times, leaving a remainder of 31.
The next digit of our result is 8. 
Result so far: 8.0
Deduct 688 from 719 and we're left with 31.
Fetch the next digit (9) from the dividend, attach it to 31 and continue: 319 / 86

Going ahead to step 4:
86 goes into 319 3 times with a remainder of 61.
Record the quotient 3 as the next digit in the result. 
Result so far: 83.0
The remainder is 61 after subtracting 258 from 319.
Bring next digit (4) of the dividend behind the 61 and repeat the process: 614 / 86

Advancing to step 5:
86 can be fit into 614 7 times, resulting in a remainder of 12.
The number 7 becomes the next digit in our result. 
Result so far: 837.0
Subtracting 602 from 614 leaves us with 12.
Grab the next digit (9) from the dividend, add it to 12, then carry on: 129 / 86

On to step 6:
If we divide 129 by 86, we get 1 and a remainder of 43.
Write down 1 as next digit of the result. 
Result so far: 8371.0
Subtracting 86 from 129 leaves us with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Moving on to step 7:
430 divided by 86 is 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 8371.5
Subtracting 430 from 430 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
0 divided by 86 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 8371.5
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 9:
86 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 8371.5
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 8371.5 with a remaining 0.0.
