376123 divided by 77 
The aim is to understand the frequency of 77 in 376123.

Moving on to step 1:
77 can be fit into 3 0 times, resulting in a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Append the next digit (7) from the dividend to 3 and continue with: 37 / 77

Advancing to step 2:
When dividing 37 by 77, we get 0 with a remainder of 37.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 37 and we're left with 37.
Grab the next digit (6) from the dividend, add it to 37, then carry on: 376 / 77

Going ahead to step 3:
The number 77 fits into 376 4 times, leaving a remainder of 68.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtract 308 from 376 to get 68.
Append the next digit (1) from the dividend to 68 and continue with: 681 / 77

Going ahead to step 4:
When dividing 681 by 77, we get 8 with a remainder of 65.
Use 8 as the next digit of our solution. 
Result so far: 48.0
Subtracting 616 from 681 leaves us with 65.
Include the next digit (2) from the dividend after 65, then repeat: 652 / 77

Let's proceed to step 5:
When dividing 652 by 77, we get 8 with a remainder of 36.
Record the quotient 8 as the next digit in the result. 
Result so far: 488.0
Subtracting 616 from 652 leaves us with 36.
Append the next digit (3) from the dividend to 36 and continue with: 363 / 77

Going ahead to step 6:
When dividing 363 by 77, we get 4 with a remainder of 55.
Record the quotient 4 as the next digit in the result. 
Result so far: 4884.0
If we take 308 away from 363, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 7:
77 can be fit into 550 7 times, resulting in a remainder of 11.
The number 7 becomes the next digit in our result. 
Result so far: 4884.7
The remainder is 11 after subtracting 539 from 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 8:
If we divide 110 by 77, we get 1 and a remainder of 33.
Use 1 as the next digit of our solution. 
Result so far: 4884.71
Subtracting 77 from 110 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Let's proceed to step 9:
The number 77 fits into 330 4 times, leaving a remainder of 22.
Put 4 as the next digit of the answer. 
Result so far: 4884.714
If we subtract 308 from 330, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 10:
If we divide 220 by 77, we get 2 and a remainder of 66.
Put 2 as the next digit of the answer. 
Result so far: 4884.7142
The remainder is 66 after subtracting 154 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Going ahead to step 11:
The number 77 fits into 660 8 times, leaving a remainder of 44.
Write down 8 as next digit of the result. 
Result so far: 4884.71428
Deduct 616 from 660 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 12:
If we divide 440 by 77, we get 5 and a remainder of 55.
The number 5 becomes the next digit in our result. 
Result so far: 4884.714285
Deduct 385 from 440 and we're left with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Moving on to step 13:
77 can be fit into 550 7 times, resulting in a remainder of 11.
Record the quotient 7 as the next digit in the result. 
Result so far: 4884.7142857
If we take 539 away from 550, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 14:
77 can be fit into 110 1 times, resulting in a remainder of 33.
Use 1 as the next digit of our solution. 
Result so far: 4884.71428571
Subtracting 77 from 110 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Our division results in 4884.71428571 with a remaining 3.3e-08.
