80591514 ÷ 784 
The aim is to understand the frequency of 784 in 80591514.

Step 1:
If we divide 8 by 784, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 784

Moving on to step 2:
80 divided by 784 is 0 with a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 80 leaves us with 80.
Fetch the next digit (5) from the dividend, attach it to 80 and continue: 805 / 784

Moving on to step 3:
When dividing 805 by 784, we get 1 with a remainder of 21.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 784 from 805 to get 21.
Bring next digit (9) of the dividend behind the 21 and repeat the process: 219 / 784

Moving on to step 4:
If we divide 219 by 784, we get 0 and a remainder of 219.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Subtracting 0 from 219 leaves us with 219.
Fetch the next digit (1) from the dividend, attach it to 219 and continue: 2191 / 784

Let's proceed to step 5:
When dividing 2191 by 784, we get 2 with a remainder of 623.
The number 2 becomes the next digit in our result. 
Result so far: 102.0
The remainder is 623 after subtracting 1568 from 2191.
Include the next digit (5) from the dividend after 623, then repeat: 6235 / 784

Let's proceed to step 6:
If we divide 6235 by 784, we get 7 and a remainder of 747.
The number 7 becomes the next digit in our result. 
Result so far: 1027.0
Subtract 5488 from 6235 to get 747.
Fetch the next digit (1) from the dividend, attach it to 747 and continue: 7471 / 784

Let's proceed to step 7:
7471 divided by 784 is 9 with a remainder of 415.
Use 9 as the next digit of our solution. 
Result so far: 10279.0
If we subtract 7056 from 7471, we get 415.
Append the next digit (4) from the dividend to 415 and continue with: 4154 / 784

On to step 8:
784 can be fit into 4154 5 times, resulting in a remainder of 234.
Record the quotient 5 as the next digit in the result. 
Result so far: 102795.0
Subtracting 3920 from 4154 leaves us with 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

Let's proceed to step 9:
If we divide 2340 by 784, we get 2 and a remainder of 772.
Put 2 as the next digit of the answer. 
Result so far: 102795.2
The remainder is 772 after subtracting 1568 from 2340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7720, and continue the process.

Moving on to step 10:
784 goes into 7720 9 times with a remainder of 664.
The number 9 becomes the next digit in our result. 
Result so far: 102795.29
Deduct 7056 from 7720 and we're left with 664.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6640, and continue the process.

Going ahead to step 11:
6640 divided by 784 is 8 with a remainder of 368.
Use 8 as the next digit of our solution. 
Result so far: 102795.298
If we subtract 6272 from 6640, we get 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Going ahead to step 12:
3680 divided by 784 is 4 with a remainder of 544.
The next digit of our result is 4. 
Result so far: 102795.2984
Subtract 3136 from 3680 to get 544.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

Advancing to step 13:
The number 784 fits into 5440 6 times, leaving a remainder of 736.
The next digit of our result is 6. 
Result so far: 102795.29846
Subtracting 4704 from 5440 leaves us with 736.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7360, and continue the process.

Moving on to step 14:
7360 divided by 784 is 9 with a remainder of 304.
Use 9 as the next digit of our solution. 
Result so far: 102795.298469
If we take 7056 away from 7360, we end up with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Step 15:
When dividing 3040 by 784, we get 3 with a remainder of 688.
The next digit of our result is 3. 
Result so far: 102795.2984693
Subtracting 2352 from 3040 leaves us with 688.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6880, and continue the process.

On to step 16:
6880 divided by 784 is 8 with a remainder of 608.
Use 8 as the next digit of our solution. 
Result so far: 102795.29846938
Subtract 6272 from 6880 to get 608.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6080, and continue the process.

The quotient of the division is 102795.29846938, and the remainder is 6.08e-07.
