86678871 ÷ 718 
The aim is to understand the frequency of 718 in 86678871.

Step 1:
The number 718 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 718

Let's proceed to step 2:
86 divided by 718 is 0 with a remainder of 86.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 86, we get 86.
Fetch the next digit (6) from the dividend, attach it to 86 and continue: 866 / 718

Going ahead to step 3:
When dividing 866 by 718, we get 1 with a remainder of 148.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 718 from 866, we get 148.
Take the next digit (7) from the dividend and append it to 148, then repeat: 1487 / 718

Let's proceed to step 4:
1487 divided by 718 is 2 with a remainder of 51.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Subtract 1436 from 1487 to get 51.
Fetch the next digit (8) from the dividend, attach it to 51 and continue: 518 / 718

Let's proceed to step 5:
718 goes into 518 0 times with a remainder of 518.
Write down 0 as next digit of the result. 
Result so far: 120.0
If we take 0 away from 518, we end up with 518.
Fetch the next digit (8) from the dividend, attach it to 518 and continue: 5188 / 718

On to step 6:
When dividing 5188 by 718, we get 7 with a remainder of 162.
The number 7 becomes the next digit in our result. 
Result so far: 1207.0
The remainder is 162 after subtracting 5026 from 5188.
Take the next digit (7) from the dividend and append it to 162, then repeat: 1627 / 718

Step 7:
The number 718 fits into 1627 2 times, leaving a remainder of 191.
Write down 2 as next digit of the result. 
Result so far: 12072.0
Subtracting 1436 from 1627 leaves us with 191.
Bring next digit (1) of the dividend behind the 191 and repeat the process: 1911 / 718

Step 8:
The number 718 fits into 1911 2 times, leaving a remainder of 475.
Use 2 as the next digit of our solution. 
Result so far: 120722.0
The remainder is 475 after subtracting 1436 from 1911.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4750, and continue the process.

On to step 9:
4750 divided by 718 is 6 with a remainder of 442.
The next digit of our result is 6. 
Result so far: 120722.6
If we take 4308 away from 4750, we end up with 442.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4420, and continue the process.

Advancing to step 10:
4420 divided by 718 is 6 with a remainder of 112.
Put 6 as the next digit of the answer. 
Result so far: 120722.66
The remainder is 112 after subtracting 4308 from 4420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

In conclusion, the division gives 120722.66 with a balance of 0.112.
