76654648 ÷ 77 
The aim is to understand the frequency of 77 in 76654648.

Step 1:
77 goes into 7 0 times 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.
Bring next digit (6) of the dividend behind the 7 and repeat the process: 76 / 77

Advancing to step 2:
When dividing 76 by 77, we get 0 with a remainder of 76.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 76, we get 76.
Take the next digit (6) from the dividend and append it to 76, then repeat: 766 / 77

Moving on to step 3:
766 divided by 77 is 9 with a remainder of 73.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we subtract 693 from 766, we get 73.
Grab the next digit (5) from the dividend, add it to 73, then carry on: 735 / 77

Let's proceed to step 4:
The number 77 fits into 735 9 times, leaving a remainder of 42.
The number 9 becomes the next digit in our result. 
Result so far: 99.0
Subtracting 693 from 735 leaves us with 42.
Bring next digit (4) of the dividend behind the 42 and repeat the process: 424 / 77

Advancing to step 5:
The number 77 fits into 424 5 times, leaving a remainder of 39.
Record the quotient 5 as the next digit in the result. 
Result so far: 995.0
The remainder is 39 after subtracting 385 from 424.
Grab the next digit (6) from the dividend, add it to 39, then carry on: 396 / 77

Step 6:
396 divided by 77 is 5 with a remainder of 11.
Put 5 as the next digit of the answer. 
Result so far: 9955.0
If we subtract 385 from 396, we get 11.
Take the next digit (4) from the dividend and append it to 11, then repeat: 114 / 77

Moving on to step 7:
114 divided by 77 is 1 with a remainder of 37.
The number 1 becomes the next digit in our result. 
Result so far: 99551.0
The remainder is 37 after subtracting 77 from 114.
Append the next digit (8) from the dividend to 37 and continue with: 378 / 77

Going ahead to step 8:
77 goes into 378 4 times with a remainder of 70.
Write down 4 as next digit of the result. 
Result so far: 995514.0
If we take 308 away from 378, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 9:
When dividing 700 by 77, we get 9 with a remainder of 7.
Put 9 as the next digit of the answer. 
Result so far: 995514.9
The remainder is 7 after subtracting 693 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 10:
The number 77 fits into 70 0 times, leaving a remainder of 70.
The next digit of our result is 0. 
Result so far: 995514.9
Subtracting 0 from 70 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 11:
When dividing 700 by 77, we get 9 with a remainder of 7.
Put 9 as the next digit of the answer. 
Result so far: 995514.909
The remainder is 7 after subtracting 693 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 12:
When dividing 70 by 77, we get 0 with a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 995514.909
The remainder is 70 after subtracting 0 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 13:
77 can be fit into 700 9 times, resulting in a remainder of 7.
Put 9 as the next digit of the answer. 
Result so far: 995514.90909
The remainder is 7 after subtracting 693 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 14:
The number 77 fits into 70 0 times, leaving a remainder of 70.
The next digit of our result is 0. 
Result so far: 995514.90909
Subtract 0 from 70 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 15:
If we divide 700 by 77, we get 9 and a remainder of 7.
Put 9 as the next digit of the answer. 
Result so far: 995514.9090909
Subtracting 693 from 700 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 16:
The number 77 fits into 70 0 times, leaving a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 995514.9090909
Subtract 0 from 70 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

The quotient of the division is 995514.9090909, and the remainder is 7e-08.
