73120659 divided by 366 
The aim is to understand the frequency of 366 in 73120659.

Step 1:
When dividing 7 by 366, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (3) from the dividend to 7 and continue with: 73 / 366

Advancing to step 2:
366 can be fit into 73 0 times, resulting in a remainder of 73.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 73 after subtracting 0 from 73.
Include the next digit (1) from the dividend after 73, then repeat: 731 / 366

Moving on to step 3:
366 can be fit into 731 1 times, resulting in a remainder of 365.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 366 from 731, we get 365.
Append the next digit (2) from the dividend to 365 and continue with: 3652 / 366

Let's proceed to step 4:
If we divide 3652 by 366, we get 9 and a remainder of 358.
The next digit of our result is 9. 
Result so far: 19.0
If we subtract 3294 from 3652, we get 358.
Grab the next digit (0) from the dividend, add it to 358, then carry on: 3580 / 366

On to step 5:
When dividing 3580 by 366, we get 9 with a remainder of 286.
Use 9 as the next digit of our solution. 
Result so far: 199.0
If we take 3294 away from 3580, we end up with 286.
Take the next digit (6) from the dividend and append it to 286, then repeat: 2866 / 366

Moving on to step 6:
2866 divided by 366 is 7 with a remainder of 304.
Write down 7 as next digit of the result. 
Result so far: 1997.0
Deduct 2562 from 2866 and we're left with 304.
Fetch the next digit (5) from the dividend, attach it to 304 and continue: 3045 / 366

Step 7:
When dividing 3045 by 366, we get 8 with a remainder of 117.
Write down 8 as next digit of the result. 
Result so far: 19978.0
If we subtract 2928 from 3045, we get 117.
Grab the next digit (9) from the dividend, add it to 117, then carry on: 1179 / 366

Going ahead to step 8:
The number 366 fits into 1179 3 times, leaving a remainder of 81.
Put 3 as the next digit of the answer. 
Result so far: 199783.0
If we take 1098 away from 1179, we end up with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Going ahead to step 9:
The number 366 fits into 810 2 times, leaving a remainder of 78.
The number 2 becomes the next digit in our result. 
Result so far: 199783.2
The remainder is 78 after subtracting 732 from 810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Advancing to step 10:
When dividing 780 by 366, we get 2 with a remainder of 48.
Write down 2 as next digit of the result. 
Result so far: 199783.22
Deduct 732 from 780 and we're left 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.

The final result is 199783.22 with a remainder of 0.048.
