We're dividing 36064024 by 661 
The aim is to understand the frequency of 661 in 36064024.

Moving on to step 1:
The number 661 fits into 3 0 times, leaving a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Take the next digit (6) from the dividend and append it to 3, then repeat: 36 / 661

On to step 2:
The number 661 fits into 36 0 times, leaving a remainder of 36.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 36, we end up with 36.
Bring next digit (0) of the dividend behind the 36 and repeat the process: 360 / 661

Going ahead to step 3:
The number 661 fits into 360 0 times, leaving a remainder of 360.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 360 and we're left with 360.
Bring next digit (6) of the dividend behind the 360 and repeat the process: 3606 / 661

Let's proceed to step 4:
661 can be fit into 3606 5 times, resulting in a remainder of 301.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
The remainder is 301 after subtracting 3305 from 3606.
Append the next digit (4) from the dividend to 301 and continue with: 3014 / 661

Going ahead to step 5:
When dividing 3014 by 661, we get 4 with a remainder of 370.
Put 4 as the next digit of the answer. 
Result so far: 54.0
Subtract 2644 from 3014 to get 370.
Grab the next digit (0) from the dividend, add it to 370, then carry on: 3700 / 661

Step 6:
When dividing 3700 by 661, we get 5 with a remainder of 395.
Record the quotient 5 as the next digit in the result. 
Result so far: 545.0
Deduct 3305 from 3700 and we're left with 395.
Bring next digit (2) of the dividend behind the 395 and repeat the process: 3952 / 661

On to step 7:
661 goes into 3952 5 times with a remainder of 647.
Put 5 as the next digit of the answer. 
Result so far: 5455.0
If we take 3305 away from 3952, we end up with 647.
Bring next digit (4) of the dividend behind the 647 and repeat the process: 6474 / 661

Going ahead to step 8:
6474 divided by 661 is 9 with a remainder of 525.
Use 9 as the next digit of our solution. 
Result so far: 54559.0
The remainder is 525 after subtracting 5949 from 6474.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5250, and continue the process.

Step 9:
661 can be fit into 5250 7 times, resulting in a remainder of 623.
Write down 7 as next digit of the result. 
Result so far: 54559.7
Subtracting 4627 from 5250 leaves us with 623.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6230, and continue the process.

Moving on to step 10:
When dividing 6230 by 661, we get 9 with a remainder of 281.
The number 9 becomes the next digit in our result. 
Result so far: 54559.79
If we subtract 5949 from 6230, we get 281.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2810, and continue the process.

Moving on to step 11:
2810 divided by 661 is 4 with a remainder of 166.
Use 4 as the next digit of our solution. 
Result so far: 54559.794
Deduct 2644 from 2810 and we're left with 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Moving on to step 12:
The number 661 fits into 1660 2 times, leaving a remainder of 338.
The next digit of our result is 2. 
Result so far: 54559.7942
Subtract 1322 from 1660 to get 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

On to step 13:
3380 divided by 661 is 5 with a remainder of 75.
Put 5 as the next digit of the answer. 
Result so far: 54559.79425
Subtract 3305 from 3380 to get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Going ahead to step 14:
750 divided by 661 is 1 with a remainder of 89.
The next digit of our result is 1. 
Result so far: 54559.794251
If we subtract 661 from 750, we get 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Advancing to step 15:
The number 661 fits into 890 1 times, leaving a remainder of 229.
Use 1 as the next digit of our solution. 
Result so far: 54559.7942511
Deduct 661 from 890 and we're left with 229.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2290, and continue the process.

The final outcome is 54559.7942511, with a leftover of 2.29e-06.
