We divide 627584 by 77
The aim is to understand the frequency of 77 in 627584.

Going ahead to step 1:
6 divided by 77 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (2) from the dividend to 6 and continue with: 62 / 77

Advancing to step 2:
When dividing 62 by 77, we get 0 with a remainder of 62.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 62, we get 62.
Bring next digit (7) of the dividend behind the 62 and repeat the process: 627 / 77

Step 3:
The number 77 fits into 627 8 times, leaving a remainder of 11.
The next digit of our result is 8. 
Result so far: 8.0
Subtracting 616 from 627 leaves us with 11.
Grab the next digit (5) from the dividend, add it to 11, then carry on: 115 / 77

Going ahead to step 4:
When dividing 115 by 77, we get 1 with a remainder of 38.
Write down 1 as next digit of the result. 
Result so far: 81.0
The remainder is 38 after subtracting 77 from 115.
Include the next digit (8) from the dividend after 38, then repeat: 388 / 77

Going ahead to step 5:
If we divide 388 by 77, we get 5 and a remainder of 3.
Record the quotient 5 as the next digit in the result. 
Result so far: 815.0
If we take 385 away from 388, we end up with 3.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 77

Going ahead to step 6:
34 divided by 77 is 0 with a remainder of 34.
Use 0 as the next digit of our solution. 
Result so far: 8150.0
If we subtract 0 from 34, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 7:
The number 77 fits into 340 4 times, leaving a remainder of 32.
Write down 4 as next digit of the result. 
Result so far: 8150.4
Subtract 308 from 340 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 8:
320 divided by 77 is 4 with a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 8150.44
Deduct 308 from 320 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Our division results in 8150.44 with a remaining 0.012.
