253721 ÷ 77 
The aim is to understand the frequency of 77 in 253721.

Moving on to step 1:
When dividing 2 by 77, we get 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 77

Advancing to step 2:
77 goes into 25 0 times with a remainder of 25.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 25 after subtracting 0 from 25.
Grab the next digit (3) from the dividend, add it to 25, then carry on: 253 / 77

Let's proceed to step 3:
77 goes into 253 3 times with a remainder of 22.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 231 away from 253, we end up with 22.
Include the next digit (7) from the dividend after 22, then repeat: 227 / 77

Going ahead to step 4:
77 goes into 227 2 times with a remainder of 73.
The number 2 becomes the next digit in our result. 
Result so far: 32.0
If we subtract 154 from 227, we get 73.
Take the next digit (2) from the dividend and append it to 73, then repeat: 732 / 77

Going ahead to step 5:
732 divided by 77 is 9 with a remainder of 39.
Use 9 as the next digit of our solution. 
Result so far: 329.0
Subtract 693 from 732 to get 39.
Append the next digit (1) from the dividend to 39 and continue with: 391 / 77

Let's proceed to step 6:
391 divided by 77 is 5 with a remainder of 6.
The next digit of our result is 5. 
Result so far: 3295.0
If we take 385 away from 391, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 7:
The number 77 fits into 60 0 times, leaving a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 3295.0
Subtracting 0 from 60 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 8:
The number 77 fits into 600 7 times, leaving a remainder of 61.
Put 7 as the next digit of the answer. 
Result so far: 3295.07
Subtracting 539 from 600 leaves us with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Moving on to step 9:
610 divided by 77 is 7 with a remainder of 71.
Use 7 as the next digit of our solution. 
Result so far: 3295.077
Deduct 539 from 610 and we're left with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

In conclusion, the division gives 3295.077 with a balance of 0.0071.
