We're dividing 86015849 by 662 
The aim is to understand the frequency of 662 in 86015849.

Let's proceed to step 1:
662 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 662

Step 2:
The number 662 fits into 86 0 times, leaving 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.
Bring next digit (0) of the dividend behind the 86 and repeat the process: 860 / 662

Going ahead to step 3:
860 divided by 662 is 1 with a remainder of 198.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 662 from 860 leaves us with 198.
Include the next digit (1) from the dividend after 198, then repeat: 1981 / 662

Let's proceed to step 4:
The number 662 fits into 1981 2 times, leaving a remainder of 657.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Subtracting 1324 from 1981 leaves us with 657.
Fetch the next digit (5) from the dividend, attach it to 657 and continue: 6575 / 662

Let's proceed to step 5:
When dividing 6575 by 662, we get 9 with a remainder of 617.
Write down 9 as next digit of the result. 
Result so far: 129.0
Subtract 5958 from 6575 to get 617.
Fetch the next digit (8) from the dividend, attach it to 617 and continue: 6178 / 662

On to step 6:
The number 662 fits into 6178 9 times, leaving a remainder of 220.
Record the quotient 9 as the next digit in the result. 
Result so far: 1299.0
Subtracting 5958 from 6178 leaves us with 220.
Append the next digit (4) from the dividend to 220 and continue with: 2204 / 662

Advancing to step 7:
662 goes into 2204 3 times with a remainder of 218.
Record the quotient 3 as the next digit in the result. 
Result so far: 12993.0
Deduct 1986 from 2204 and we're left with 218.
Take the next digit (9) from the dividend and append it to 218, then repeat: 2189 / 662

Going ahead to step 8:
The number 662 fits into 2189 3 times, leaving a remainder of 203.
The number 3 becomes the next digit in our result. 
Result so far: 129933.0
Subtracting 1986 from 2189 leaves us with 203.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2030, and continue the process.

Let's proceed to step 9:
662 goes into 2030 3 times with a remainder of 44.
Record the quotient 3 as the next digit in the result. 
Result so far: 129933.3
Subtracting 1986 from 2030 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 10:
If we divide 440 by 662, we get 0 and a remainder of 440.
The next digit of our result is 0. 
Result so far: 129933.3
If we take 0 away from 440, we end up with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Step 11:
If we divide 4400 by 662, we get 6 and a remainder of 428.
Record the quotient 6 as the next digit in the result. 
Result so far: 129933.306
If we take 3972 away from 4400, we end up with 428.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

Step 12:
662 can be fit into 4280 6 times, resulting in a remainder of 308.
Put 6 as the next digit of the answer. 
Result so far: 129933.3066
Subtracting 3972 from 4280 leaves us with 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

The final outcome is 129933.3066, with a leftover of 0.00308.
