249103 ÷ 2 
The aim is to understand the frequency of 2 in 249103.

Advancing to step 1:
2 goes into 2 1 times with a remainder of 0.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 2 from 2 leaves us with 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 2

Going ahead to step 2:
When dividing 4 by 2, we get 2 with a remainder of 0.
The next digit of our result is 2. 
Result so far: 12.0
Subtract 4 from 4 to get 0.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 2

Step 3:
The number 2 fits into 9 4 times, leaving a remainder of 1.
Write down 4 as next digit of the result. 
Result so far: 124.0
Subtracting 8 from 9 leaves us with 1.
Grab the next digit (1) from the dividend, add it to 1, then carry on: 11 / 2

On to step 4:
If we divide 11 by 2, we get 5 and a remainder of 1.
Use 5 as the next digit of our solution. 
Result so far: 1245.0
The remainder is 1 after subtracting 10 from 11.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 2

Advancing to step 5:
2 goes into 10 5 times with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 12455.0
Subtracting 10 from 10 leaves us with 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 2

Step 6:
2 can be fit into 3 1 times, resulting in a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 124551.0
If we take 2 away from 3, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
The number 2 fits into 10 5 times, leaving a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 124551.5
Deduct 10 from 10 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
2 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 124551.5
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 9:
If we divide 0 by 2, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 124551.5
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 124551.5 with a remainder of 0.0.
