We look at the division of 77654689 by 277 
The aim is to understand the frequency of 277 in 77654689.

Moving on to step 1:
If we divide 7 by 277, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 277

Advancing to step 2:
If we divide 77 by 277, we get 0 and a remainder of 77.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 77 to get 77.
Append the next digit (6) from the dividend to 77 and continue with: 776 / 277

Step 3:
277 goes into 776 2 times with a remainder of 222.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 554 from 776 to get 222.
Include the next digit (5) from the dividend after 222, then repeat: 2225 / 277

Step 4:
The number 277 fits into 2225 8 times, leaving a remainder of 9.
Use 8 as the next digit of our solution. 
Result so far: 28.0
Subtract 2216 from 2225 to get 9.
Take the next digit (4) from the dividend and append it to 9, then repeat: 94 / 277

Let's proceed to step 5:
277 can be fit into 94 0 times, resulting in a remainder of 94.
The number 0 becomes the next digit in our result. 
Result so far: 280.0
Subtract 0 from 94 to get 94.
Include the next digit (6) from the dividend after 94, then repeat: 946 / 277

Let's proceed to step 6:
277 can be fit into 946 3 times, resulting in a remainder of 115.
Use 3 as the next digit of our solution. 
Result so far: 2803.0
If we take 831 away from 946, we end up with 115.
Bring next digit (8) of the dividend behind the 115 and repeat the process: 1158 / 277

Let's proceed to step 7:
When dividing 1158 by 277, we get 4 with a remainder of 50.
Put 4 as the next digit of the answer. 
Result so far: 28034.0
Subtracting 1108 from 1158 leaves us with 50.
Include the next digit (9) from the dividend after 50, then repeat: 509 / 277

Step 8:
277 can be fit into 509 1 times, resulting in a remainder of 232.
The next digit of our result is 1. 
Result so far: 280341.0
If we subtract 277 from 509, we get 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Moving on to step 9:
277 can be fit into 2320 8 times, resulting in a remainder of 104.
The next digit of our result is 8. 
Result so far: 280341.8
Subtract 2216 from 2320 to get 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Moving on to step 10:
When dividing 1040 by 277, we get 3 with a remainder of 209.
Write down 3 as next digit of the result. 
Result so far: 280341.83
The remainder is 209 after subtracting 831 from 1040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

Let's proceed to step 11:
2090 divided by 277 is 7 with a remainder of 151.
The number 7 becomes the next digit in our result. 
Result so far: 280341.837
The remainder is 151 after subtracting 1939 from 2090.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1510, and continue the process.

Let's proceed to step 12:
1510 divided by 277 is 5 with a remainder of 125.
The next digit of our result is 5. 
Result so far: 280341.8375
If we take 1385 away from 1510, we end up with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Let's proceed to step 13:
When dividing 1250 by 277, we get 4 with a remainder of 142.
The number 4 becomes the next digit in our result. 
Result so far: 280341.83754
Subtract 1108 from 1250 to get 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Let's proceed to step 14:
If we divide 1420 by 277, we get 5 and a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 280341.837545
The remainder is 35 after subtracting 1385 from 1420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 15:
If we divide 350 by 277, we get 1 and a remainder of 73.
Put 1 as the next digit of the answer. 
Result so far: 280341.8375451
Subtracting 277 from 350 leaves us with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

On to step 16:
When dividing 730 by 277, we get 2 with a remainder of 176.
Put 2 as the next digit of the answer. 
Result so far: 280341.83754512
The remainder is 176 after subtracting 554 from 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

The final result is 280341.83754512 with a remainder of 1.76e-07.
