13174864 ÷ 784 
The aim is to understand the frequency of 784 in 13174864.

Going ahead to step 1:
If we divide 1 by 784, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 784

Step 2:
13 divided by 784 is 0 with a remainder of 13.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 13 after subtracting 0 from 13.
Take the next digit (1) from the dividend and append it to 13, then repeat: 131 / 784

Advancing to step 3:
When dividing 131 by 784, we get 0 with a remainder of 131.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 131 leaves us with 131.
Fetch the next digit (7) from the dividend, attach it to 131 and continue: 1317 / 784

On to step 4:
When dividing 1317 by 784, we get 1 with a remainder of 533.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 784 from 1317 to get 533.
Bring next digit (4) of the dividend behind the 533 and repeat the process: 5334 / 784

Let's proceed to step 5:
The number 784 fits into 5334 6 times, leaving a remainder of 630.
Write down 6 as next digit of the result. 
Result so far: 16.0
The remainder is 630 after subtracting 4704 from 5334.
Append the next digit (8) from the dividend to 630 and continue with: 6308 / 784

Moving on to step 6:
784 can be fit into 6308 8 times, resulting in a remainder of 36.
Write down 8 as next digit of the result. 
Result so far: 168.0
Subtract 6272 from 6308 to get 36.
Append the next digit (6) from the dividend to 36 and continue with: 366 / 784

Moving on to step 7:
If we divide 366 by 784, we get 0 and a remainder of 366.
Write down 0 as next digit of the result. 
Result so far: 1680.0
Deduct 0 from 366 and we're left with 366.
Include the next digit (4) from the dividend after 366, then repeat: 3664 / 784

On to step 8:
3664 divided by 784 is 4 with a remainder of 528.
The number 4 becomes the next digit in our result. 
Result so far: 16804.0
Subtracting 3136 from 3664 leaves us 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 9:
When dividing 5280 by 784, we get 6 with a remainder of 576.
Record the quotient 6 as the next digit in the result. 
Result so far: 16804.6
If we subtract 4704 from 5280, we get 576.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

Going ahead to step 10:
784 can be fit into 5760 7 times, resulting in a remainder of 272.
The number 7 becomes the next digit in our result. 
Result so far: 16804.67
Subtract 5488 from 5760 to 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.

Advancing to step 11:
The number 784 fits into 2720 3 times, leaving a remainder of 368.
The number 3 becomes the next digit in our result. 
Result so far: 16804.673
Subtracting 2352 from 2720 leaves us 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.

Advancing to step 12:
The number 784 fits into 3680 4 times, leaving a remainder of 544.
Record the quotient 4 as the next digit in the result. 
Result so far: 16804.6734
Deduct 3136 from 3680 and we're left with 544.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

Let's proceed to step 13:
If we divide 5440 by 784, we get 6 and a remainder of 736.
Put 6 as the next digit of the answer. 
Result so far: 16804.67346
If we take 4704 away from 5440, we end up 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.

Going ahead to step 14:
784 can be fit into 7360 9 times, resulting in a remainder of 304.
Write down 9 as next digit of the result. 
Result so far: 16804.673469
Subtracting 7056 from 7360 leaves us 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 number 3 becomes the next digit in our result. 
Result so far: 16804.6734693
The remainder is 688 after subtracting 2352 from 3040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6880, and continue the process.

Going ahead to step 16:
784 goes into 6880 8 times with a remainder of 608.
Put 8 as the next digit of the answer. 
Result so far: 16804.67346938
If we take 6272 away from 6880, we end up with 608.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6080, and continue the process.

Our division results in 16804.67346938 with a remaining 6.08e-07.
