372680 divided by 77 
The aim is to understand the frequency of 77 in 372680.

Let's proceed to step 1:
When dividing 3 by 77, we get 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Grab the next digit (7) from the dividend, add it to 3, then carry on: 37 / 77

Going ahead to step 2:
77 can be fit into 37 0 times, resulting in a remainder of 37.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 37, we get 37.
Append the next digit (2) from the dividend to 37 and continue with: 372 / 77

On to step 3:
When dividing 372 by 77, we get 4 with a remainder of 64.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtract 308 from 372 to get 64.
Fetch the next digit (6) from the dividend, attach it to 64 and continue: 646 / 77

Step 4:
646 divided by 77 is 8 with a remainder of 30.
The next digit of our result is 8. 
Result so far: 48.0
Subtract 616 from 646 to get 30.
Append the next digit (8) from the dividend to 30 and continue with: 308 / 77

Moving on to step 5:
77 goes into 308 4 times with a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 484.0
Deduct 308 from 308 and we're left with 0.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 77

Going ahead to step 6:
When dividing 0 by 77, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 4840.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 7:
The number 77 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 4840.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 8:
77 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 4840.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 4840.0, with a leftover of 0.0.
