971762 ÷ 86 
The aim is to understand the frequency of 86 in 971762.

Step 1:
The number 86 fits into 9 0 times, leaving a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Append the next digit (7) from the dividend to 9 and continue with: 97 / 86

Let's proceed to step 2:
The number 86 fits into 97 1 times, leaving a remainder of 11.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 86 away from 97, we end up with 11.
Bring next digit (1) of the dividend behind the 11 and repeat the process: 111 / 86

On to step 3:
86 can be fit into 111 1 times, resulting in a remainder of 25.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
If we subtract 86 from 111, we get 25.
Include the next digit (7) from the dividend after 25, then repeat: 257 / 86

Going ahead to step 4:
86 goes into 257 2 times with a remainder of 85.
The next digit of our result is 2. 
Result so far: 112.0
Subtract 172 from 257 to get 85.
Include the next digit (6) from the dividend after 85, then repeat: 856 / 86

Let's proceed to step 5:
86 can be fit into 856 9 times, resulting in a remainder of 82.
Record the quotient 9 as the next digit in the result. 
Result so far: 1129.0
If we take 774 away from 856, we end up with 82.
Grab the next digit (2) from the dividend, add it to 82, then carry on: 822 / 86

On to step 6:
822 divided by 86 is 9 with a remainder of 48.
The next digit of our result is 9. 
Result so far: 11299.0
If we take 774 away from 822, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 7:
If we divide 480 by 86, we get 5 and a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 11299.5
If we subtract 430 from 480, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 8:
When dividing 500 by 86, we get 5 with a remainder of 70.
Record the quotient 5 as the next digit in the result. 
Result so far: 11299.55
If we take 430 away from 500, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

In conclusion, the division gives 11299.55 with a balance of 0.07.
