19578456 ÷ 104 
The aim is to understand the frequency of 104 in 19578456.

Step 1:
The number 104 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 104

Let's proceed to step 2:
When dividing 19 by 104, we get 0 with a remainder of 19.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 19, we get 19.
Bring next digit (5) of the dividend behind the 19 and repeat the process: 195 / 104

Going ahead to step 3:
When dividing 195 by 104, we get 1 with a remainder of 91.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 104 from 195, we get 91.
Include the next digit (7) from the dividend after 91, then repeat: 917 / 104

Step 4:
917 divided by 104 is 8 with a remainder of 85.
The next digit of our result is 8. 
Result so far: 18.0
The remainder is 85 after subtracting 832 from 917.
Grab the next digit (8) from the dividend, add it to 85, then carry on: 858 / 104

Moving on to step 5:
The number 104 fits into 858 8 times, leaving a remainder of 26.
Use 8 as the next digit of our solution. 
Result so far: 188.0
Subtracting 832 from 858 leaves us with 26.
Bring next digit (4) of the dividend behind the 26 and repeat the process: 264 / 104

On to step 6:
104 can be fit into 264 2 times, resulting in a remainder of 56.
Record the quotient 2 as the next digit in the result. 
Result so far: 1882.0
Subtract 208 from 264 to get 56.
Bring next digit (5) of the dividend behind the 56 and repeat the process: 565 / 104

Step 7:
The number 104 fits into 565 5 times, leaving a remainder of 45.
Record the quotient 5 as the next digit in the result. 
Result so far: 18825.0
Subtracting 520 from 565 leaves us with 45.
Append the next digit (6) from the dividend to 45 and continue with: 456 / 104

On to step 8:
If we divide 456 by 104, we get 4 and a remainder of 40.
The number 4 becomes the next digit in our result. 
Result so far: 188254.0
Subtracting 416 from 456 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 9:
If we divide 400 by 104, we get 3 and a remainder of 88.
Record the quotient 3 as the next digit in the result. 
Result so far: 188254.3
If we subtract 312 from 400, we get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Moving on to step 10:
If we divide 880 by 104, we get 8 and a remainder of 48.
Use 8 as the next digit of our solution. 
Result so far: 188254.38
The remainder is 48 after subtracting 832 from 880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 11:
When dividing 480 by 104, we get 4 with a remainder of 64.
Use 4 as the next digit of our solution. 
Result so far: 188254.384
The remainder is 64 after subtracting 416 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 12:
When dividing 640 by 104, we get 6 with a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 188254.3846
Subtracting 624 from 640 leaves us 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.

Going ahead to step 13:
104 goes into 160 1 times with a remainder of 56.
Put 1 as the next digit of the answer. 
Result so far: 188254.38461
Deduct 104 from 160 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 14:
When dividing 560 by 104, we get 5 with a remainder of 40.
Record the quotient 5 as the next digit in the result. 
Result so far: 188254.384615
Subtract 520 from 560 to 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.

On to step 15:
When dividing 400 by 104, we get 3 with a remainder of 88.
Put 3 as the next digit of the answer. 
Result so far: 188254.3846153
If we take 312 away from 400, we end up with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

On to step 16:
104 can be fit into 880 8 times, resulting in a remainder of 48.
The number 8 becomes the next digit in our result. 
Result so far: 188254.38461538
The remainder is 48 after subtracting 832 from 880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

The quotient of the division is 188254.38461538, and the remainder is 4.8e-08.
