Let's divide 77709582 by 549
The aim is to understand the frequency of 549 in 77709582.

Let's proceed to step 1:
549 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 549

Going ahead to step 2:
When dividing 77 by 549, we get 0 with a remainder of 77.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 77, we get 77.
Fetch the next digit (7) from the dividend, attach it to 77 and continue: 777 / 549

On to step 3:
The number 549 fits into 777 1 times, leaving a remainder of 228.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 549 from 777 leaves us with 228.
Append the next digit (0) from the dividend to 228 and continue with: 2280 / 549

Advancing to step 4:
When dividing 2280 by 549, we get 4 with a remainder of 84.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
If we take 2196 away from 2280, we end up with 84.
Include the next digit (9) from the dividend after 84, then repeat: 849 / 549

Moving on to step 5:
When dividing 849 by 549, we get 1 with a remainder of 300.
The next digit of our result is 1. 
Result so far: 141.0
If we subtract 549 from 849, we get 300.
Bring next digit (5) of the dividend behind the 300 and repeat the process: 3005 / 549

Moving on to step 6:
3005 divided by 549 is 5 with a remainder of 260.
Record the quotient 5 as the next digit in the result. 
Result so far: 1415.0
Deduct 2745 from 3005 and we're left with 260.
Fetch the next digit (8) from the dividend, attach it to 260 and continue: 2608 / 549

Let's proceed to step 7:
549 can be fit into 2608 4 times, resulting in a remainder of 412.
Use 4 as the next digit of our solution. 
Result so far: 14154.0
If we subtract 2196 from 2608, we get 412.
Append the next digit (2) from the dividend to 412 and continue with: 4122 / 549

Step 8:
The number 549 fits into 4122 7 times, leaving a remainder of 279.
Write down 7 as next digit of the result. 
Result so far: 141547.0
The remainder is 279 after subtracting 3843 from 4122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2790, and continue the process.

Step 9:
2790 divided by 549 is 5 with a remainder of 45.
Use 5 as the next digit of our solution. 
Result so far: 141547.5
Subtracting 2745 from 2790 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 10:
549 can be fit into 450 0 times, resulting in a remainder of 450.
The next digit of our result is 0. 
Result so far: 141547.5
If we subtract 0 from 450, we get 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Advancing to step 11:
If we divide 4500 by 549, we get 8 and a remainder of 108.
The next digit of our result is 8. 
Result so far: 141547.508
If we subtract 4392 from 4500, we get 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

On to step 12:
When dividing 1080 by 549, we get 1 with a remainder of 531.
The number 1 becomes the next digit in our result. 
Result so far: 141547.5081
If we take 549 away from 1080, we end up with 531.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5310, and continue the process.

Let's proceed to step 13:
The number 549 fits into 5310 9 times, leaving a remainder of 369.
The next digit of our result is 9. 
Result so far: 141547.50819
If we subtract 4941 from 5310, we get 369.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3690, and continue the process.

Moving on to step 14:
549 can be fit into 3690 6 times, resulting in a remainder of 396.
Record the quotient 6 as the next digit in the result. 
Result so far: 141547.508196
Subtracting 3294 from 3690 leaves us with 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

Moving on to step 15:
The number 549 fits into 3960 7 times, leaving a remainder of 117.
Use 7 as the next digit of our solution. 
Result so far: 141547.5081967
The remainder is 117 after subtracting 3843 from 3960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

Going ahead to step 16:
If we divide 1170 by 549, we get 2 and a remainder of 72.
Put 2 as the next digit of the answer. 
Result so far: 141547.50819672
If we take 1098 away from 1170, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Our division results in 141547.50819672 with a remaining 7.2e-08.
