99554424 ÷ 784 
The aim is to understand the frequency of 784 in 99554424.

Going ahead to step 1:
784 can be fit into 9 0 times, resulting in a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Take the next digit (9) from the dividend and append it to 9, then repeat: 99 / 784

Moving on to step 2:
99 divided by 784 is 0 with a remainder of 99.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 99 to get 99.
Include the next digit (5) from the dividend after 99, then repeat: 995 / 784

Advancing to step 3:
When dividing 995 by 784, we get 1 with a remainder of 211.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 784 away from 995, we end up with 211.
Grab the next digit (5) from the dividend, add it to 211, then carry on: 2115 / 784

Moving on to step 4:
The number 784 fits into 2115 2 times, leaving a remainder of 547.
The next digit of our result is 2. 
Result so far: 12.0
Deduct 1568 from 2115 and we're left with 547.
Append the next digit (4) from the dividend to 547 and continue with: 5474 / 784

Let's proceed to step 5:
When dividing 5474 by 784, we get 6 with a remainder of 770.
The number 6 becomes the next digit in our result. 
Result so far: 126.0
If we subtract 4704 from 5474, we get 770.
Take the next digit (4) from the dividend and append it to 770, then repeat: 7704 / 784

Advancing to step 6:
If we divide 7704 by 784, we get 9 and a remainder of 648.
The number 9 becomes the next digit in our result. 
Result so far: 1269.0
Subtracting 7056 from 7704 leaves us with 648.
Include the next digit (2) from the dividend after 648, then repeat: 6482 / 784

Going ahead to step 7:
6482 divided by 784 is 8 with a remainder of 210.
The number 8 becomes the next digit in our result. 
Result so far: 12698.0
Subtract 6272 from 6482 to get 210.
Append the next digit (4) from the dividend to 210 and continue with: 2104 / 784

Going ahead to step 8:
2104 divided by 784 is 2 with a remainder of 536.
Use 2 as the next digit of our solution. 
Result so far: 126982.0
Subtracting 1568 from 2104 leaves us with 536.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5360, and continue the process.

Advancing to step 9:
784 can be fit into 5360 6 times, resulting in a remainder of 656.
The next digit of our result is 6. 
Result so far: 126982.6
If we subtract 4704 from 5360, we get 656.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6560, and continue the process.

Going ahead to step 10:
If we divide 6560 by 784, we get 8 and a remainder of 288.
Write down 8 as next digit of the result. 
Result so far: 126982.68
The remainder is 288 after subtracting 6272 from 6560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Let's proceed to step 11:
If we divide 2880 by 784, we get 3 and a remainder of 528.
Use 3 as the next digit of our solution. 
Result so far: 126982.683
If we take 2352 away from 2880, we end up with 528.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

Step 12:
5280 divided by 784 is 6 with a remainder of 576.
Put 6 as the next digit of the answer. 
Result so far: 126982.6836
The remainder is 576 after subtracting 4704 from 5280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

Moving on to step 13:
784 can be fit into 5760 7 times, resulting in a remainder of 272.
Record the quotient 7 as the next digit in the result. 
Result so far: 126982.68367
If we subtract 5488 from 5760, we get 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Going ahead to step 14:
When dividing 2720 by 784, we get 3 with a remainder of 368.
The number 3 becomes the next digit in our result. 
Result so far: 126982.683673
If we take 2352 away from 2720, we end up with 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Moving on to step 15:
When dividing 3680 by 784, we get 4 with a remainder of 544.
The number 4 becomes the next digit in our result. 
Result so far: 126982.6836734
If we subtract 3136 from 3680, we 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.

On to step 16:
5440 divided by 784 is 6 with a remainder of 736.
The next digit of our result is 6. 
Result so far: 126982.68367346
The remainder is 736 after subtracting 4704 from 5440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7360, and continue the process.

Our division results in 126982.68367346 with a remaining 7.36e-07.
