142355 ÷ 77 
The aim is to understand the frequency of 77 in 142355.

On to step 1:
77 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 77

On to step 2:
77 goes into 14 0 times with a remainder of 14.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 14, we end up with 14.
Grab the next digit (2) from the dividend, add it to 14, then carry on: 142 / 77

Step 3:
77 can be fit into 142 1 times, resulting in a remainder of 65.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 77 away from 142, we end up with 65.
Fetch the next digit (3) from the dividend, attach it to 65 and continue: 653 / 77

Advancing to step 4:
The number 77 fits into 653 8 times, leaving a remainder of 37.
Put 8 as the next digit of the answer. 
Result so far: 18.0
Subtract 616 from 653 to get 37.
Include the next digit (5) from the dividend after 37, then repeat: 375 / 77

Step 5:
If we divide 375 by 77, we get 4 and a remainder of 67.
Put 4 as the next digit of the answer. 
Result so far: 184.0
If we take 308 away from 375, we end up with 67.
Fetch the next digit (5) from the dividend, attach it to 67 and continue: 675 / 77

Let's proceed to step 6:
675 divided by 77 is 8 with a remainder of 59.
Use 8 as the next digit of our solution. 
Result so far: 1848.0
The remainder is 59 after subtracting 616 from 675.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Step 7:
The number 77 fits into 590 7 times, leaving a remainder of 51.
Put 7 as the next digit of the answer. 
Result so far: 1848.7
If we take 539 away from 590, we end up with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Advancing to step 8:
When dividing 510 by 77, we get 6 with a remainder of 48.
The next digit of our result is 6. 
Result so far: 1848.76
If we subtract 462 from 510, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 9:
77 can be fit into 480 6 times, resulting in a remainder of 18.
The next digit of our result is 6. 
Result so far: 1848.766
If we subtract 462 from 480, we get 18.
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 1848.766, and the remainder is 0.0018.
