799610 ÷ 77 
The aim is to understand the frequency of 77 in 799610.

Step 1:
7 divided by 77 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Append the next digit (9) from the dividend to 7 and continue with: 79 / 77

Going ahead to step 2:
79 divided by 77 is 1 with a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 2 after subtracting 77 from 79.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 77

Let's proceed to step 3:
When dividing 29 by 77, we get 0 with a remainder of 29.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
If we subtract 0 from 29, we get 29.
Append the next digit (6) from the dividend to 29 and continue with: 296 / 77

Advancing to step 4:
The number 77 fits into 296 3 times, leaving a remainder of 65.
The next digit of our result is 3. 
Result so far: 103.0
If we subtract 231 from 296, we get 65.
Grab the next digit (1) from the dividend, add it to 65, then carry on: 651 / 77

Going ahead to step 5:
If we divide 651 by 77, we get 8 and a remainder of 35.
Record the quotient 8 as the next digit in the result. 
Result so far: 1038.0
Subtracting 616 from 651 leaves us with 35.
Take the next digit (0) from the dividend and append it to 35, then repeat: 350 / 77

Advancing to step 6:
The number 77 fits into 350 4 times, leaving a remainder of 42.
Put 4 as the next digit of the answer. 
Result so far: 10384.0
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.

On to step 7:
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: 10384.5
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.

Moving on to step 8:
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: 10384.54
If we subtract 308 from 350, we 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:
When dividing 420 by 77, we get 5 with a remainder of 35.
The next digit of our result is 5. 
Result so far: 10384.545
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.

On to step 10:
350 divided by 77 is 4 with a remainder of 42.
Put 4 as the next digit of the answer. 
Result so far: 10384.5454
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.

On to step 11:
When dividing 420 by 77, we get 5 with a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 10384.54545
The remainder is 35 after subtracting 385 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 12:
77 can be fit into 350 4 times, resulting in a remainder of 42.
The next digit of our result is 4. 
Result so far: 10384.545454
Deduct 308 from 350 and we're left 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.

On to step 13:
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: 10384.5454545
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.

Going ahead to step 14:
77 goes into 350 4 times with a remainder of 42.
Put 4 as the next digit of the answer. 
Result so far: 10384.54545454
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.

The quotient of the division is 10384.54545454, and the remainder is 4.2e-08.
