We look at the division of 13933590 by 776 
The aim is to understand the frequency of 776 in 13933590.

Step 1:
When dividing 1 by 776, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 776

Advancing to step 2:
The number 776 fits into 13 0 times, leaving a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 13 after subtracting 0 from 13.
Include the next digit (9) from the dividend after 13, then repeat: 139 / 776

Going ahead to step 3:
776 goes into 139 0 times with a remainder of 139.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 139 to get 139.
Include the next digit (3) from the dividend after 139, then repeat: 1393 / 776

Moving on to step 4:
776 goes into 1393 1 times with a remainder of 617.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 776 away from 1393, we end up with 617.
Grab the next digit (3) from the dividend, add it to 617, then carry on: 6173 / 776

Moving on to step 5:
6173 divided by 776 is 7 with a remainder of 741.
Write down 7 as next digit of the result. 
Result so far: 17.0
If we subtract 5432 from 6173, we get 741.
Take the next digit (5) from the dividend and append it to 741, then repeat: 7415 / 776

Moving on to step 6:
776 goes into 7415 9 times with a remainder of 431.
Put 9 as the next digit of the answer. 
Result so far: 179.0
Subtracting 6984 from 7415 leaves us with 431.
Take the next digit (9) from the dividend and append it to 431, then repeat: 4319 / 776

On to step 7:
When dividing 4319 by 776, we get 5 with a remainder of 439.
The next digit of our result is 5. 
Result so far: 1795.0
If we take 3880 away from 4319, we end up with 439.
Take the next digit (0) from the dividend and append it to 439, then repeat: 4390 / 776

On to step 8:
If we divide 4390 by 776, we get 5 and a remainder of 510.
Record the quotient 5 as the next digit in the result. 
Result so far: 17955.0
Deduct 3880 from 4390 and we're left with 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

Let's proceed to step 9:
When dividing 5100 by 776, we get 6 with a remainder of 444.
Use 6 as the next digit of our solution. 
Result so far: 17955.6
Deduct 4656 from 5100 and we're left with 444.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4440, and continue the process.

Let's proceed to step 10:
If we divide 4440 by 776, we get 5 and a remainder of 560.
The number 5 becomes the next digit in our result. 
Result so far: 17955.65
The remainder is 560 after subtracting 3880 from 4440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Going ahead to step 11:
If we divide 5600 by 776, we get 7 and a remainder of 168.
Write down 7 as next digit of the result. 
Result so far: 17955.657
Deduct 5432 from 5600 and we're left with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Step 12:
When dividing 1680 by 776, we get 2 with a remainder of 128.
The number 2 becomes the next digit in our result. 
Result so far: 17955.6572
The remainder is 128 after subtracting 1552 from 1680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Moving on to step 13:
The number 776 fits into 1280 1 times, leaving a remainder of 504.
Record the quotient 1 as the next digit in the result. 
Result so far: 17955.65721
If we subtract 776 from 1280, we get 504.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5040, and continue the process.

Step 14:
When dividing 5040 by 776, we get 6 with a remainder of 384.
The number 6 becomes the next digit in our result. 
Result so far: 17955.657216
If we subtract 4656 from 5040, we get 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Step 15:
776 can be fit into 3840 4 times, resulting in a remainder of 736.
Record the quotient 4 as the next digit in the result. 
Result so far: 17955.6572164
If we subtract 3104 from 3840, we get 736.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7360, and continue the process.

Going ahead to step 16:
776 can be fit into 7360 9 times, resulting in a remainder of 376.
Record the quotient 9 as the next digit in the result. 
Result so far: 17955.65721649
The remainder is 376 after subtracting 6984 from 7360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

After the division, we end up with 17955.65721649 and a remainder of 3.76e-07.
