52485 divided by 77 
The aim is to understand the frequency of 77 in 52485.

Step 1:
When dividing 5 by 77, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Fetch the next digit (2) from the dividend, attach it to 5 and continue: 52 / 77

Advancing to step 2:
77 can be fit into 52 0 times, resulting in a remainder of 52.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 52 and we're left with 52.
Grab the next digit (4) from the dividend, add it to 52, then carry on: 524 / 77

Advancing to step 3:
77 goes into 524 6 times with a remainder of 62.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we subtract 462 from 524, we get 62.

On to step 4:
The number 77 fits into 628 8 times, leaving a remainder of 12.
The next digit of our result is 8. 
Result so far: 68.0
If we subtract 616 from 628, we get 12.
Grab the next digit (5) from the dividend, add it to 12, then carry on: 125 / 77

Moving on to step 5:
The number 77 fits into 125 1 times, leaving a remainder of 48.
The next digit of our result is 1. 
Result so far: 681.0
Subtract 77 from 125 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 6:
480 divided by 77 is 6 with a remainder of 18.
Write down 6 as next digit of the result. 
Result so far: 681.6
Subtract 462 from 480 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 7:
When dividing 180 by 77, we get 2 with a remainder of 26.
Write down 2 as next digit of the result. 
Result so far: 681.62
If we subtract 154 from 180, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 8:
The number 77 fits into 260 3 times, leaving a remainder of 29.
Use 3 as the next digit of our solution. 
Result so far: 681.623
Subtract 231 from 260 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 9:
290 divided by 77 is 3 with a remainder of 59.
The next digit of our result is 3. 
Result so far: 681.6233
Deduct 231 from 290 and we're left with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Our division results in 681.6233 with a remaining 0.00059.
