We divide 553062 by 77
The aim is to understand the frequency of 77 in 553062.

Moving on to step 1:
When dividing 5 by 77, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Fetch the next digit (5) from the dividend, attach it to 5 and continue: 55 / 77

Going ahead to step 2:
77 goes into 55 0 times with a remainder of 55.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 55 and we're left with 55.
Include the next digit (3) from the dividend after 55, then repeat: 553 / 77

Going ahead to step 3:
When dividing 553 by 77, we get 7 with a remainder of 14.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we take 539 away from 553, we end up with 14.
Take the next digit (0) from the dividend and append it to 14, then repeat: 140 / 77

Let's proceed to step 4:
When dividing 140 by 77, we get 1 with a remainder of 63.
The next digit of our result is 1. 
Result so far: 71.0
Subtracting 77 from 140 leaves us with 63.
Append the next digit (6) from the dividend to 63 and continue with: 636 / 77

Step 5:
77 goes into 636 8 times with a remainder of 20.
Record the quotient 8 as the next digit in the result. 
Result so far: 718.0
Subtracting 616 from 636 leaves us with 20.
Append the next digit (2) from the dividend to 20 and continue with: 202 / 77

Let's proceed to step 6:
77 goes into 202 2 times with a remainder of 48.
The next digit of our result is 2. 
Result so far: 7182.0
The remainder is 48 after subtracting 154 from 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 7:
480 divided by 77 is 6 with a remainder of 18.
The next digit of our result is 6. 
Result so far: 7182.6
Subtracting 462 from 480 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 8:
The number 77 fits into 180 2 times, leaving a remainder of 26.
Use 2 as the next digit of our solution. 
Result so far: 7182.62
Subtract 154 from 180 to 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.

Moving on to step 9:
When dividing 260 by 77, we get 3 with a remainder of 29.
Put 3 as the next digit of the answer. 
Result so far: 7182.623
If we subtract 231 from 260, we 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 10:
When dividing 290 by 77, we get 3 with a remainder of 59.
Use 3 as the next digit of our solution. 
Result so far: 7182.6233
Subtracting 231 from 290 leaves us 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.

After the division, we end up with 7182.6233 and a remainder of 0.00059.
