We look at the division of 7779487 by 784 
The aim is to understand the frequency of 784 in 7779487.

Going ahead to step 1:
784 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 784

Let's proceed to step 2:
The number 784 fits into 77 0 times, leaving a remainder of 77.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 77 after subtracting 0 from 77.
Grab the next digit (7) from the dividend, add it to 77, then carry on: 777 / 784

Let's proceed to step 3:
784 can be fit into 777 0 times, resulting in a remainder of 777.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 777, we end up with 777.
Grab the next digit (9) from the dividend, add it to 777, then carry on: 7779 / 784

Let's proceed to step 4:
784 goes into 7779 9 times with a remainder of 723.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we take 7056 away from 7779, we end up with 723.
Append the next digit (4) from the dividend to 723 and continue with: 7234 / 784

Step 5:
784 can be fit into 7234 9 times, resulting in a remainder of 178.
The next digit of our result is 9. 
Result so far: 99.0
If we subtract 7056 from 7234, we get 178.
Grab the next digit (8) from the dividend, add it to 178, then carry on: 1788 / 784

Going ahead to step 6:
When dividing 1788 by 784, we get 2 with a remainder of 220.
Write down 2 as next digit of the result. 
Result so far: 992.0
Subtracting 1568 from 1788 leaves us with 220.
Take the next digit (7) from the dividend and append it to 220, then repeat: 2207 / 784

Let's proceed to step 7:
The number 784 fits into 2207 2 times, leaving a remainder of 639.
Use 2 as the next digit of our solution. 
Result so far: 9922.0
Subtracting 1568 from 2207 leaves us with 639.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6390, and continue the process.

Advancing to step 8:
784 goes into 6390 8 times with a remainder of 118.
The number 8 becomes the next digit in our result. 
Result so far: 9922.8
If we take 6272 away from 6390, we end up with 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Step 9:
784 goes into 1180 1 times with a remainder of 396.
Use 1 as the next digit of our solution. 
Result so far: 9922.81
The remainder is 396 after subtracting 784 from 1180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

Going ahead to step 10:
The number 784 fits into 3960 5 times, leaving a remainder of 40.
Use 5 as the next digit of our solution. 
Result so far: 9922.815
If we subtract 3920 from 3960, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 11:
The number 784 fits into 400 0 times, leaving a remainder of 400.
Record the quotient 0 as the next digit in the result. 
Result so far: 9922.815
Subtracting 0 from 400 leaves us with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Step 12:
If we divide 4000 by 784, we get 5 and a remainder of 80.
The number 5 becomes the next digit in our result. 
Result so far: 9922.81505
Subtracting 3920 from 4000 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 13:
784 goes into 800 1 times with a remainder of 16.
Put 1 as the next digit of the answer. 
Result so far: 9922.815051
If we take 784 away from 800, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 14:
784 goes into 160 0 times with a remainder of 160.
The number 0 becomes the next digit in our result. 
Result so far: 9922.815051
Deduct 0 from 160 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Going ahead to step 15:
784 can be fit into 1600 2 times, resulting in a remainder of 32.
The number 2 becomes the next digit in our result. 
Result so far: 9922.81505102
The remainder is 32 after subtracting 1568 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The quotient of the division is 9922.81505102, and the remainder is 3.2e-08.
