Let's divide 86511682 by 742
The aim is to understand the frequency of 742 in 86511682.

Going ahead to step 1:
8 divided by 742 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 742

Going ahead to step 2:
If we divide 86 by 742, we get 0 and a remainder of 86.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 86 after subtracting 0 from 86.
Include the next digit (5) from the dividend after 86, then repeat: 865 / 742

Advancing to step 3:
865 divided by 742 is 1 with a remainder of 123.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 123 after subtracting 742 from 865.
Grab the next digit (1) from the dividend, add it to 123, then carry on: 1231 / 742

Let's proceed to step 4:
742 goes into 1231 1 times with a remainder of 489.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
The remainder is 489 after subtracting 742 from 1231.
Bring next digit (1) of the dividend behind the 489 and repeat the process: 4891 / 742

Going ahead to step 5:
742 goes into 4891 6 times with a remainder of 439.
Put 6 as the next digit of the answer. 
Result so far: 116.0
Subtracting 4452 from 4891 leaves us with 439.
Bring next digit (6) of the dividend behind the 439 and repeat the process: 4396 / 742

Step 6:
742 can be fit into 4396 5 times, resulting in a remainder of 686.
Put 5 as the next digit of the answer. 
Result so far: 1165.0
If we subtract 3710 from 4396, we get 686.
Include the next digit (8) from the dividend after 686, then repeat: 6868 / 742

Step 7:
The number 742 fits into 6868 9 times, leaving a remainder of 190.
Use 9 as the next digit of our solution. 
Result so far: 11659.0
Subtract 6678 from 6868 to get 190.
Take the next digit (2) from the dividend and append it to 190, then repeat: 1902 / 742

Moving on to step 8:
The number 742 fits into 1902 2 times, leaving a remainder of 418.
Write down 2 as next digit of the result. 
Result so far: 116592.0
Subtracting 1484 from 1902 leaves us with 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

Let's proceed to step 9:
If we divide 4180 by 742, we get 5 and a remainder of 470.
Record the quotient 5 as the next digit in the result. 
Result so far: 116592.5
Subtract 3710 from 4180 to get 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Advancing to step 10:
If we divide 4700 by 742, we get 6 and a remainder of 248.
Put 6 as the next digit of the answer. 
Result so far: 116592.56
The remainder is 248 after subtracting 4452 from 4700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Advancing to step 11:
2480 divided by 742 is 3 with a remainder of 254.
The number 3 becomes the next digit in our result. 
Result so far: 116592.563
Deduct 2226 from 2480 and we're left with 254.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

Going ahead to step 12:
If we divide 2540 by 742, we get 3 and a remainder of 314.
The next digit of our result is 3. 
Result so far: 116592.5633
Subtracting 2226 from 2540 leaves us with 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

After the division, we end up with 116592.5633 and a remainder of 0.00314.
