We look at the division of 574032 by 77 
The aim is to understand the frequency of 77 in 574032.

Going ahead to step 1:
If we divide 5 by 77, we get 0 and a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Grab the next digit (7) from the dividend, add it to 5, then carry on: 57 / 77

Step 2:
The number 77 fits into 57 0 times, leaving a remainder of 57.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 57 after subtracting 0 from 57.
Grab the next digit (4) from the dividend, add it to 57, then carry on: 574 / 77

Going ahead to step 3:
574 divided by 77 is 7 with a remainder of 35.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we subtract 539 from 574, we get 35.
Include the next digit (0) from the dividend after 35, then repeat: 350 / 77

On to step 4:
77 can be fit into 350 4 times, resulting in a remainder of 42.
The next digit of our result is 4. 
Result so far: 74.0
Deduct 308 from 350 and we're left with 42.
Include the next digit (3) from the dividend after 42, then repeat: 423 / 77

Advancing to step 5:
When dividing 423 by 77, we get 5 with a remainder of 38.
Write down 5 as next digit of the result. 
Result so far: 745.0
Subtracting 385 from 423 leaves us with 38.
Grab the next digit (2) from the dividend, add it to 38, then carry on: 382 / 77

Going ahead to step 6:
When dividing 382 by 77, we get 4 with a remainder of 74.
The number 4 becomes the next digit in our result. 
Result so far: 7454.0
Subtract 308 from 382 to get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

On to step 7:
77 can be fit into 740 9 times, resulting in a remainder of 47.
Record the quotient 9 as the next digit in the result. 
Result so far: 7454.9
Subtracting 693 from 740 leaves us with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Advancing to step 8:
The number 77 fits into 470 6 times, leaving a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 7454.96
The remainder is 8 after subtracting 462 from 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 9:
80 divided by 77 is 1 with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 7454.961
If we subtract 77 from 80, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 10:
When dividing 30 by 77, we get 0 with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 7454.961
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 11:
The number 77 fits into 300 3 times, leaving a remainder of 69.
The next digit of our result is 3. 
Result so far: 7454.96103
Subtract 231 from 300 to get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Advancing to step 12:
690 divided by 77 is 8 with a remainder of 74.
The number 8 becomes the next digit in our result. 
Result so far: 7454.961038
If we subtract 616 from 690, we get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Let's proceed to step 13:
77 goes into 740 9 times with a remainder of 47.
The next digit of our result is 9. 
Result so far: 7454.9610389
Subtract 693 from 740 to get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Going ahead to step 14:
77 can be fit into 470 6 times, resulting in a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 7454.96103896
Subtract 462 from 470 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

After the division, we end up with 7454.96103896 and a remainder of 8e-09.
