1807048 ÷ 103 
The aim is to understand the frequency of 103 in 1807048.

Going ahead to step 1:
103 can be fit into 1 0 times, resulting in a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 103

Going ahead to step 2:
If we divide 18 by 103, we get 0 and a remainder of 18.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 18 after subtracting 0 from 18.
Grab the next digit (0) from the dividend, add it to 18, then carry on: 180 / 103

Moving on to step 3:
103 can be fit into 180 1 times, resulting in a remainder of 77.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 103 from 180 to get 77.
Take the next digit (7) from the dividend and append it to 77, then repeat: 777 / 103

On to step 4:
The number 103 fits into 777 7 times, leaving a remainder of 56.
The next digit of our result is 7. 
Result so far: 17.0
The remainder is 56 after subtracting 721 from 777.
Bring next digit (0) of the dividend behind the 56 and repeat the process: 560 / 103

Let's proceed to step 5:
The number 103 fits into 560 5 times, leaving a remainder of 45.
Use 5 as the next digit of our solution. 
Result so far: 175.0
The remainder is 45 after subtracting 515 from 560.
Grab the next digit (4) from the dividend, add it to 45, then carry on: 454 / 103

Moving on to step 6:
103 can be fit into 454 4 times, resulting in a remainder of 42.
Put 4 as the next digit of the answer. 
Result so far: 1754.0
Subtracting 412 from 454 leaves us with 42.
Fetch the next digit (8) from the dividend, attach it to 42 and continue: 428 / 103

Moving on to step 7:
The number 103 fits into 428 4 times, leaving a remainder of 16.
The next digit of our result is 4. 
Result so far: 17544.0
Deduct 412 from 428 and we're left 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.

Step 8:
If we divide 160 by 103, we get 1 and a remainder of 57.
Use 1 as the next digit of our solution. 
Result so far: 17544.1
If we subtract 103 from 160, we get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Going ahead to step 9:
When dividing 570 by 103, we get 5 with a remainder of 55.
The number 5 becomes the next digit in our result. 
Result so far: 17544.15
Deduct 515 from 570 and we're left with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Let's proceed to step 10:
103 can be fit into 550 5 times, resulting in a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 17544.155
Subtracting 515 from 550 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

The quotient of the division is 17544.155, and the remainder is 0.0035.
