We divide 276539 by 77
The aim is to understand the frequency of 77 in 276539.

Let's proceed to step 1:
2 divided by 77 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Include the next digit (7) from the dividend after 2, then repeat: 27 / 77

Advancing to step 2:
The number 77 fits into 27 0 times, leaving a remainder of 27.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 27 leaves us with 27.
Include the next digit (6) from the dividend after 27, then repeat: 276 / 77

On to step 3:
If we divide 276 by 77, we get 3 and a remainder of 45.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Deduct 231 from 276 and we're left with 45.
Include the next digit (5) from the dividend after 45, then repeat: 455 / 77

Advancing to step 4:
The number 77 fits into 455 5 times, leaving a remainder of 70.
Record the quotient 5 as the next digit in the result. 
Result so far: 35.0
Subtract 385 from 455 to get 70.
Include the next digit (3) from the dividend after 70, then repeat: 703 / 77

On to step 5:
If we divide 703 by 77, we get 9 and a remainder of 10.
Use 9 as the next digit of our solution. 
Result so far: 359.0
Subtract 693 from 703 to get 10.
Bring next digit (9) of the dividend behind the 10 and repeat the process: 109 / 77

On to step 6:
If we divide 109 by 77, we get 1 and a remainder of 32.
The next digit of our result is 1. 
Result so far: 3591.0
Subtracting 77 from 109 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 7:
77 goes into 320 4 times with a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 3591.4
If we take 308 away from 320, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 8:
120 divided by 77 is 1 with a remainder of 43.
Use 1 as the next digit of our solution. 
Result so far: 3591.41
The remainder is 43 after subtracting 77 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Going ahead to step 9:
The number 77 fits into 430 5 times, leaving a remainder of 45.
Use 5 as the next digit of our solution. 
Result so far: 3591.415
If we take 385 away from 430, we end up 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.

Step 10:
The number 77 fits into 450 5 times, leaving a remainder of 65.
Record the quotient 5 as the next digit in the result. 
Result so far: 3591.4155
If we take 385 away from 450, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

In conclusion, the division gives 3591.4155 with a balance of 0.00065.
