We look at the division of 77339030 by 277 
The aim is to understand the frequency of 277 in 77339030.

Step 1:
If we divide 7 by 277, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 277

Moving on to step 2:
277 can be fit into 77 0 times, resulting in a remainder of 77.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 77 and we're left with 77.
Include the next digit (3) from the dividend after 77, then repeat: 773 / 277

Going ahead to step 3:
When dividing 773 by 277, we get 2 with a remainder of 219.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 554 from 773 leaves us with 219.
Grab the next digit (3) from the dividend, add it to 219, then carry on: 2193 / 277

Step 4:
277 goes into 2193 7 times with a remainder of 254.
The number 7 becomes the next digit in our result. 
Result so far: 27.0
Subtracting 1939 from 2193 leaves us with 254.
Include the next digit (9) from the dividend after 254, then repeat: 2549 / 277

On to step 5:
When dividing 2549 by 277, we get 9 with a remainder of 56.
Use 9 as the next digit of our solution. 
Result so far: 279.0
Subtracting 2493 from 2549 leaves us with 56.
Include the next digit (0) from the dividend after 56, then repeat: 560 / 277

Step 6:
277 can be fit into 560 2 times, resulting in a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 2792.0
The remainder is 6 after subtracting 554 from 560.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 277

Moving on to step 7:
The number 277 fits into 63 0 times, leaving a remainder of 63.
Use 0 as the next digit of our solution. 
Result so far: 27920.0
If we take 0 away from 63, we end up with 63.
Grab the next digit (0) from the dividend, add it to 63, then carry on: 630 / 277

Let's proceed to step 8:
277 goes into 630 2 times with a remainder of 76.
Record the quotient 2 as the next digit in the result. 
Result so far: 279202.0
Subtracting 554 from 630 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 9:
277 goes into 760 2 times with a remainder of 206.
Put 2 as the next digit of the answer. 
Result so far: 279202.2
The remainder is 206 after subtracting 554 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

Going ahead to step 10:
When dividing 2060 by 277, we get 7 with a remainder of 121.
The number 7 becomes the next digit in our result. 
Result so far: 279202.27
Deduct 1939 from 2060 and we're left with 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Let's proceed to step 11:
277 can be fit into 1210 4 times, resulting in a remainder of 102.
Use 4 as the next digit of our solution. 
Result so far: 279202.274
If we subtract 1108 from 1210, we get 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

On to step 12:
The number 277 fits into 1020 3 times, leaving a remainder of 189.
Record the quotient 3 as the next digit in the result. 
Result so far: 279202.2743
If we take 831 away from 1020, we end up with 189.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1890, and continue the process.

Let's proceed to step 13:
The number 277 fits into 1890 6 times, leaving a remainder of 228.
Record the quotient 6 as the next digit in the result. 
Result so far: 279202.27436
The remainder is 228 after subtracting 1662 from 1890.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Let's proceed to step 14:
277 goes into 2280 8 times with a remainder of 64.
The number 8 becomes the next digit in our result. 
Result so far: 279202.274368
Subtract 2216 from 2280 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 15:
277 can be fit into 640 2 times, resulting in a remainder of 86.
Put 2 as the next digit of the answer. 
Result so far: 279202.2743682
The remainder is 86 after subtracting 554 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Step 16:
When dividing 860 by 277, we get 3 with a remainder of 29.
Put 3 as the next digit of the answer. 
Result so far: 279202.27436823
If we subtract 831 from 860, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

In conclusion, the division gives 279202.27436823 with a balance of 2.9e-08.
