The aim is to understand the frequency of 784 in 69808393.

Advancing to step 1:
The number 784 fits into 6 0 times, leaving a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (9) from the dividend, attach it to 6 and continue: 69 / 784

On to step 2:
The number 784 fits into 69 0 times, leaving a remainder of 69.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 69 and we're left with 69.
Append the next digit (8) from the dividend to 69 and continue with: 698 / 784

Going ahead to step 3:
The number 784 fits into 698 0 times, leaving a remainder of 698.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 698 to get 698.
Grab the next digit (0) from the dividend, add it to 698, then carry on: 6980 / 784

On to step 4:
784 can be fit into 6980 8 times, resulting in a remainder of 708.
Put 8 as the next digit of the answer. 
Result so far: 8.0
The remainder is 708 after subtracting 6272 from 6980.
Take the next digit (8) from the dividend and append it to 708, then repeat: 7088 / 784

Moving on to step 5:
If we divide 7088 by 784, we get 9 and a remainder of 32.
The next digit of our result is 9. 
Result so far: 89.0
Subtracting 7056 from 7088 leaves us with 32.
Fetch the next digit (3) from the dividend, attach it to 32 and continue: 323 / 784

Advancing to step 6:
The number 784 fits into 323 0 times, leaving a remainder of 323.
Use 0 as the next digit of our solution. 
Result so far: 890.0
Deduct 0 from 323 and we're left with 323.
Append the next digit (9) from the dividend to 323 and continue with: 3239 / 784

Moving on to step 7:
3239 divided by 784 is 4 with a remainder of 103.
Record the quotient 4 as the next digit in the result. 
Result so far: 8904.0
Deduct 3136 from 3239 and we're left with 103.
Append the next digit (3) from the dividend to 103 and continue with: 1033 / 784

On to step 8:
The number 784 fits into 1033 1 times, leaving a remainder of 249.
The number 1 becomes the next digit in our result. 
Result so far: 89041.0
Deduct 784 from 1033 and we're left with 249.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2490, and continue the process.

On to step 9:
When dividing 2490 by 784, we get 3 with a remainder of 138.
Record the quotient 3 as the next digit in the result. 
Result so far: 89041.3
If we take 2352 away from 2490, we end up with 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Let's proceed to step 10:
The number 784 fits into 1380 1 times, leaving a remainder of 596.
Put 1 as the next digit of the answer. 
Result so far: 89041.31
Deduct 784 from 1380 and we're left with 596.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5960, and continue the process.

Advancing to step 11:
784 goes into 5960 7 times with a remainder of 472.
Record the quotient 7 as the next digit in the result. 
Result so far: 89041.317
If we subtract 5488 from 5960, we get 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

Let's proceed to step 12:
4720 divided by 784 is 6 with a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 89041.3176
If we take 4704 away from 4720, 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.

Let's proceed to step 13:
The number 784 fits into 160 0 times, leaving a remainder of 160.
Put 0 as the next digit of the answer. 
Result so far: 89041.3176
If we take 0 away from 160, we end up 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.

Step 14:
784 goes into 1600 2 times with a remainder of 32.
The number 2 becomes the next digit in our result. 
Result so far: 89041.317602
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.

On to step 15:
If we divide 320 by 784, we get 0 and a remainder of 320.
Put 0 as the next digit of the answer. 
Result so far: 89041.317602
If we take 0 away from 320, we end up with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Step 16:
If we divide 3200 by 784, we get 4 and a remainder of 64.
The next digit of our result is 4. 
Result so far: 89041.31760204
Subtract 3136 from 3200 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The final result is 89041.31760204 with a remainder of 6.4e-08.
