955587 ÷ 77 
The aim is to understand the frequency of 77 in 955587.

Advancing to step 1:
When dividing 9 by 77, we get 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Fetch the next digit (5) from the dividend, attach it to 9 and continue: 95 / 77

Advancing to step 2:
77 can be fit into 95 1 times, resulting in a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 18 after subtracting 77 from 95.
Include the next digit (5) from the dividend after 18, then repeat: 185 / 77

Let's proceed to step 3:
185 divided by 77 is 2 with a remainder of 31.
The next digit of our result is 2. 
Result so far: 12.0
The remainder is 31 after subtracting 154 from 185.
Take the next digit (5) from the dividend and append it to 31, then repeat: 315 / 77

Step 4:
315 divided by 77 is 4 with a remainder of 7.
Record the quotient 4 as the next digit in the result. 
Result so far: 124.0
If we take 308 away from 315, we end up with 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 77

On to step 5:
When dividing 78 by 77, we get 1 with a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 1241.0
If we take 77 away from 78, we end up with 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 77

On to step 6:
77 goes into 17 0 times with a remainder of 17.
Put 0 as the next digit of the answer. 
Result so far: 12410.0
If we take 0 away from 17, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 7:
77 goes into 170 2 times with a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 12410.2
Subtract 154 from 170 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 8:
77 can be fit into 160 2 times, resulting in a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 12410.22
If we subtract 154 from 160, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The quotient of the division is 12410.22, and the remainder is 0.006.
