342624 divided by 77 
The aim is to understand the frequency of 77 in 342624.

Moving on to step 1:
77 can be fit into 3 0 times, resulting in a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 77

Going ahead to step 2:
77 goes into 34 0 times with a remainder of 34.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 34, we get 34.
Append the next digit (2) from the dividend to 34 and continue with: 342 / 77

Moving on to step 3:
77 goes into 342 4 times with a remainder of 34.
The next digit of our result is 4. 
Result so far: 4.0
If we take 308 away from 342, we end up with 34.
Include the next digit (6) from the dividend after 34, then repeat: 346 / 77

On to step 4:
77 can be fit into 346 4 times, resulting in a remainder of 38.
The number 4 becomes the next digit in our result. 
Result so far: 44.0
The remainder is 38 after subtracting 308 from 346.
Grab the next digit (2) from the dividend, add it to 38, then carry on: 382 / 77

Step 5:
77 can be fit into 382 4 times, resulting in a remainder of 74.
The next digit of our result is 4. 
Result so far: 444.0
If we subtract 308 from 382, we get 74.
Bring next digit (4) of the dividend behind the 74 and repeat the process: 744 / 77

On to step 6:
The number 77 fits into 744 9 times, leaving a remainder of 51.
The next digit of our result is 9. 
Result so far: 4449.0
Subtract 693 from 744 to get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Going ahead to step 7:
When dividing 510 by 77, we get 6 with a remainder of 48.
The number 6 becomes the next digit in our result. 
Result so far: 4449.6
If we take 462 away from 510, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 8:
When dividing 480 by 77, we get 6 with a remainder of 18.
Write down 6 as next digit of the result. 
Result so far: 4449.66
The remainder is 18 after subtracting 462 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The quotient of the division is 4449.66, and the remainder is 0.018.
