322980 divided by 77 
The aim is to understand the frequency of 77 in 322980.

Step 1:
77 can be fit into 3 0 times, resulting in a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (2) from the dividend, add it to 3, then carry on: 32 / 77

Step 2:
When dividing 32 by 77, we get 0 with a remainder of 32.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 32 to get 32.
Fetch the next digit (2) from the dividend, attach it to 32 and continue: 322 / 77

Advancing to step 3:
The number 77 fits into 322 4 times, leaving a remainder of 14.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we take 308 away from 322, we end up with 14.
Bring next digit (9) of the dividend behind the 14 and repeat the process: 149 / 77

Going ahead to step 4:
77 goes into 149 1 times with a remainder of 72.
Use 1 as the next digit of our solution. 
Result so far: 41.0
Subtract 77 from 149 to get 72.
Include the next digit (8) from the dividend after 72, then repeat: 728 / 77

On to step 5:
77 can be fit into 728 9 times, resulting in a remainder of 35.
The next digit of our result is 9. 
Result so far: 419.0
Deduct 693 from 728 and we're left with 35.
Grab the next digit (0) from the dividend, add it to 35, then carry on: 350 / 77

Moving on to step 6:
The number 77 fits into 350 4 times, leaving a remainder of 42.
The next digit of our result is 4. 
Result so far: 4194.0
If we take 308 away from 350, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 7:
77 can be fit into 420 5 times, resulting in a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 4194.5
Subtracting 385 from 420 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 8:
77 goes into 350 4 times with a remainder of 42.
Use 4 as the next digit of our solution. 
Result so far: 4194.54
Subtract 308 from 350 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 9:
77 can be fit into 420 5 times, resulting in a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 4194.545
Deduct 385 from 420 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 10:
77 can be fit into 350 4 times, resulting in a remainder of 42.
Put 4 as the next digit of the answer. 
Result so far: 4194.5454
If we take 308 away from 350, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 11:
If we divide 420 by 77, we get 5 and a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 4194.54545
If we subtract 385 from 420, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 12:
If we divide 350 by 77, we get 4 and a remainder of 42.
The next digit of our result is 4. 
Result so far: 4194.545454
Subtracting 308 from 350 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 13:
When dividing 420 by 77, we get 5 with a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 4194.5454545
Deduct 385 from 420 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 14:
77 goes into 350 4 times with a remainder of 42.
Record the quotient 4 as the next digit in the result. 
Result so far: 4194.54545454
Subtract 308 from 350 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

After the division, we end up with 4194.54545454 and a remainder of 4.2e-08.
