647698 ÷ 86 
The aim is to understand the frequency of 86 in 647698.

Step 1:
6 divided by 86 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 86

Going ahead to step 2:
The number 86 fits into 64 0 times, leaving a remainder of 64.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 64, we get 64.
Fetch the next digit (7) from the dividend, attach it to 64 and continue: 647 / 86

Let's proceed to step 3:
The number 86 fits into 647 7 times, leaving a remainder of 45.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we take 602 away from 647, we end up with 45.
Grab the next digit (6) from the dividend, add it to 45, then carry on: 456 / 86

Advancing to step 4:
86 goes into 456 5 times with a remainder of 26.
Use 5 as the next digit of our solution. 
Result so far: 75.0
If we take 430 away from 456, we end up with 26.
Append the next digit (9) from the dividend to 26 and continue with: 269 / 86

Moving on to step 5:
If we divide 269 by 86, we get 3 and a remainder of 11.
The next digit of our result is 3. 
Result so far: 753.0
The remainder is 11 after subtracting 258 from 269.
Include the next digit (8) from the dividend after 11, then repeat: 118 / 86

On to step 6:
The number 86 fits into 118 1 times, leaving a remainder of 32.
Record the quotient 1 as the next digit in the result. 
Result so far: 7531.0
Subtracting 86 from 118 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 7:
The number 86 fits into 320 3 times, leaving a remainder of 62.
The next digit of our result is 3. 
Result so far: 7531.3
Subtracting 258 from 320 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Moving on to step 8:
620 divided by 86 is 7 with a remainder of 18.
Use 7 as the next digit of our solution. 
Result so far: 7531.37
The remainder is 18 after subtracting 602 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 9:
When dividing 180 by 86, we get 2 with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 7531.372
If we subtract 172 from 180, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 10:
86 goes into 80 0 times with a remainder of 80.
The next digit of our result is 0. 
Result so far: 7531.372
Deduct 0 from 80 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 11:
800 divided by 86 is 9 with a remainder of 26.
The next digit of our result is 9. 
Result so far: 7531.37209
Deduct 774 from 800 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 12:
260 divided by 86 is 3 with a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 7531.372093
Subtract 258 from 260 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 13:
86 can be fit into 20 0 times, resulting in a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 7531.372093
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 14:
If we divide 200 by 86, we get 2 and a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 7531.37209302
The remainder is 28 after subtracting 172 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

In conclusion, the division gives 7531.37209302 with a balance of 2.8e-08.
