88657551 divided by 777 
The aim is to understand the frequency of 777 in 88657551.

Let's proceed to step 1:
The number 777 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (8) from the dividend, add it to 8, then carry on: 88 / 777

Moving on to step 2:
88 divided by 777 is 0 with a remainder of 88.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 88 to get 88.
Take the next digit (6) from the dividend and append it to 88, then repeat: 886 / 777

Going ahead to step 3:
The number 777 fits into 886 1 times, leaving a remainder of 109.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 777 from 886, we get 109.
Grab the next digit (5) from the dividend, add it to 109, then carry on: 1095 / 777

Moving on to step 4:
1095 divided by 777 is 1 with a remainder of 318.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Deduct 777 from 1095 and we're left with 318.
Append the next digit (7) from the dividend to 318 and continue with: 3187 / 777

Step 5:
The number 777 fits into 3187 4 times, leaving a remainder of 79.
Write down 4 as next digit of the result. 
Result so far: 114.0
Deduct 3108 from 3187 and we're left with 79.
Take the next digit (5) from the dividend and append it to 79, then repeat: 795 / 777

Step 6:
777 can be fit into 795 1 times, resulting in a remainder of 18.
The number 1 becomes the next digit in our result. 
Result so far: 1141.0
Subtract 777 from 795 to get 18.
Grab the next digit (5) from the dividend, add it to 18, then carry on: 185 / 777

Moving on to step 7:
777 can be fit into 185 0 times, resulting in a remainder of 185.
Record the quotient 0 as the next digit in the result. 
Result so far: 11410.0
If we take 0 away from 185, we end up with 185.
Include the next digit (1) from the dividend after 185, then repeat: 1851 / 777

Let's proceed to step 8:
1851 divided by 777 is 2 with a remainder of 297.
The next digit of our result is 2. 
Result so far: 114102.0
If we take 1554 away from 1851, we end up with 297.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2970, and continue the process.

Let's proceed to step 9:
The number 777 fits into 2970 3 times, leaving a remainder of 639.
The next digit of our result is 3. 
Result so far: 114102.3
Subtracting 2331 from 2970 leaves us with 639.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6390, and continue the process.

Let's proceed to step 10:
When dividing 6390 by 777, we get 8 with a remainder of 174.
Record the quotient 8 as the next digit in the result. 
Result so far: 114102.38
Subtracting 6216 from 6390 leaves us with 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Moving on to step 11:
The number 777 fits into 1740 2 times, leaving a remainder of 186.
Write down 2 as next digit of the result. 
Result so far: 114102.382
Deduct 1554 from 1740 and we're left with 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Moving on to step 12:
777 can be fit into 1860 2 times, resulting in a remainder of 306.
The number 2 becomes the next digit in our result. 
Result so far: 114102.3822
If we take 1554 away from 1860, we end up with 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

The final result is 114102.3822 with a remainder of 0.00306.
