596380 ÷ 77 
The aim is to understand the frequency of 77 in 596380.

Let's proceed to step 1:
When dividing 5 by 77, we get 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Bring next digit (9) of the dividend behind the 5 and repeat the process: 59 / 77

Step 2:
77 can be fit into 59 0 times, resulting in a remainder of 59.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 59, we end up with 59.
Append the next digit (6) from the dividend to 59 and continue with: 596 / 77

Going ahead to step 3:
77 can be fit into 596 7 times, resulting in a remainder of 57.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtract 539 from 596 to get 57.
Grab the next digit (3) from the dividend, add it to 57, then carry on: 573 / 77

Going ahead to step 4:
If we divide 573 by 77, we get 7 and a remainder of 34.
Record the quotient 7 as the next digit in the result. 
Result so far: 77.0
The remainder is 34 after subtracting 539 from 573.
Bring next digit (8) of the dividend behind the 34 and repeat the process: 348 / 77

Let's proceed to step 5:
348 divided by 77 is 4 with a remainder of 40.
The next digit of our result is 4. 
Result so far: 774.0
Subtracting 308 from 348 leaves us with 40.
Grab the next digit (0) from the dividend, add it to 40, then carry on: 400 / 77

On to step 6:
77 can be fit into 400 5 times, resulting in a remainder of 15.
The next digit of our result is 5. 
Result so far: 7745.0
Subtract 385 from 400 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 7:
When dividing 150 by 77, we get 1 with a remainder of 73.
Record the quotient 1 as the next digit in the result. 
Result so far: 7745.1
The remainder is 73 after subtracting 77 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Moving on to step 8:
77 can be fit into 730 9 times, resulting in a remainder of 37.
Write down 9 as next digit of the result. 
Result so far: 7745.19
Deduct 693 from 730 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 9:
If we divide 370 by 77, we get 4 and a remainder of 62.
Write down 4 as next digit of the result. 
Result so far: 7745.194
Subtract 308 from 370 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Moving on to step 10:
77 can be fit into 620 8 times, resulting in a remainder of 4.
The next digit of our result is 8. 
Result so far: 7745.1948
Subtracting 616 from 620 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 11:
77 goes into 40 0 times with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 7745.1948
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 12:
77 can be fit into 400 5 times, resulting in a remainder of 15.
The next digit of our result is 5. 
Result so far: 7745.194805
The remainder is 15 after subtracting 385 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 13:
150 divided by 77 is 1 with a remainder of 73.
Record the quotient 1 as the next digit in the result. 
Result so far: 7745.1948051
If we take 77 away from 150, we end up 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 14:
730 divided by 77 is 9 with a remainder of 37.
Record the quotient 9 as the next digit in the result. 
Result so far: 7745.19480519
Subtracting 693 from 730 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

The final result is 7745.19480519 with a remainder of 3.7e-08.
