739945 ÷ 86 
The aim is to understand the frequency of 86 in 739945.

Advancing 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
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (3) from the dividend, attach it to 7 and continue: 73 / 86

Let's proceed to step 2:
The number 86 fits into 73 0 times, leaving a remainder of 73.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 73, we end up with 73.
Include the next digit (9) from the dividend after 73, then repeat: 739 / 86

Advancing to step 3:
If we divide 739 by 86, we get 8 and a remainder of 51.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
The remainder is 51 after subtracting 688 from 739.
Include the next digit (9) from the dividend after 51, then repeat: 519 / 86

Let's proceed to step 4:
519 divided by 86 is 6 with a remainder of 3.
Write down 6 as next digit of the result. 
Result so far: 86.0
Deduct 516 from 519 and we're left with 3.
Append the next digit (4) from the dividend to 3 and continue with: 34 / 86

Moving on to step 5:
86 goes into 34 0 times with a remainder of 34.
Use 0 as the next digit of our solution. 
Result so far: 860.0
Deduct 0 from 34 and we're left with 34.
Include the next digit (5) from the dividend after 34, then repeat: 345 / 86

Step 6:
If we divide 345 by 86, we get 4 and a remainder of 1.
The number 4 becomes the next digit in our result. 
Result so far: 8604.0
If we subtract 344 from 345, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 7:
86 goes into 10 0 times with a remainder of 10.
The next digit of our result is 0. 
Result so far: 8604.0
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
100 divided by 86 is 1 with a remainder of 14.
Write down 1 as next digit of the result. 
Result so far: 8604.01
Deduct 86 from 100 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 9:
86 can be fit into 140 1 times, resulting in a remainder of 54.
Use 1 as the next digit of our solution. 
Result so far: 8604.011
If we subtract 86 from 140, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Our division results in 8604.011 with a remaining 0.0054.
