75664139 ÷ 779 
The aim is to understand the frequency of 779 in 75664139.

Moving on to step 1:
779 can be fit into 7 0 times, resulting in a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (5) from the dividend, add it to 7, then carry on: 75 / 779

On to step 2:
The number 779 fits into 75 0 times, leaving a remainder of 75.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 75 leaves us with 75.
Grab the next digit (6) from the dividend, add it to 75, then carry on: 756 / 779

Going ahead to step 3:
779 goes into 756 0 times with a remainder of 756.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 756 after subtracting 0 from 756.
Fetch the next digit (6) from the dividend, attach it to 756 and continue: 7566 / 779

Step 4:
If we divide 7566 by 779, we get 9 and a remainder of 555.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Deduct 7011 from 7566 and we're left with 555.
Take the next digit (4) from the dividend and append it to 555, then repeat: 5554 / 779

Step 5:
When dividing 5554 by 779, we get 7 with a remainder of 101.
Write down 7 as next digit of the result. 
Result so far: 97.0
Subtracting 5453 from 5554 leaves us with 101.
Grab the next digit (1) from the dividend, add it to 101, then carry on: 1011 / 779

Step 6:
The number 779 fits into 1011 1 times, leaving a remainder of 232.
Use 1 as the next digit of our solution. 
Result so far: 971.0
If we take 779 away from 1011, we end up with 232.
Grab the next digit (3) from the dividend, add it to 232, then carry on: 2323 / 779

Advancing to step 7:
2323 divided by 779 is 2 with a remainder of 765.
The number 2 becomes the next digit in our result. 
Result so far: 9712.0
The remainder is 765 after subtracting 1558 from 2323.
Bring next digit (9) of the dividend behind the 765 and repeat the process: 7659 / 779

Let's proceed to step 8:
If we divide 7659 by 779, we get 9 and a remainder of 648.
Write down 9 as next digit of the result. 
Result so far: 97129.0
Subtract 7011 from 7659 to get 648.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6480, and continue the process.

Going ahead to step 9:
If we divide 6480 by 779, we get 8 and a remainder of 248.
Put 8 as the next digit of the answer. 
Result so far: 97129.8
The remainder is 248 after subtracting 6232 from 6480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Going ahead to step 10:
If we divide 2480 by 779, we get 3 and a remainder of 143.
The next digit of our result is 3. 
Result so far: 97129.83
The remainder is 143 after subtracting 2337 from 2480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

On to step 11:
If we divide 1430 by 779, we get 1 and a remainder of 651.
The next digit of our result is 1. 
Result so far: 97129.831
If we subtract 779 from 1430, we get 651.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6510, and continue the process.

Moving on to step 12:
779 can be fit into 6510 8 times, resulting in a remainder of 278.
Record the quotient 8 as the next digit in the result. 
Result so far: 97129.8318
If we subtract 6232 from 6510, we get 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

Going ahead to step 13:
2780 divided by 779 is 3 with a remainder of 443.
Record the quotient 3 as the next digit in the result. 
Result so far: 97129.83183
If we take 2337 away from 2780, we end up with 443.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4430, and continue the process.

Advancing to step 14:
4430 divided by 779 is 5 with a remainder of 535.
Use 5 as the next digit of our solution. 
Result so far: 97129.831835
If we take 3895 away from 4430, we end up with 535.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5350, and continue the process.

Moving on to step 15:
The number 779 fits into 5350 6 times, leaving a remainder of 676.
Write down 6 as next digit of the result. 
Result so far: 97129.8318356
Subtracting 4674 from 5350 leaves us with 676.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6760, and continue the process.

Advancing to step 16:
6760 divided by 779 is 8 with a remainder of 528.
The next digit of our result is 8. 
Result so far: 97129.83183568
The remainder is 528 after subtracting 6232 from 6760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

The quotient of the division is 97129.83183568, and the remainder is 5.28e-07.
