251947 divided by 2 
The aim is to understand the frequency of 2 in 251947.

Step 1:
When dividing 2 by 2, we get 1 with a remainder of 0.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 0 after subtracting 2 from 2.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 2

Moving on to step 2:
The number 2 fits into 5 2 times, leaving a remainder of 1.
The next digit of our result is 2. 
Result so far: 12.0
Deduct 4 from 5 and we're left with 1.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 2

On to step 3:
When dividing 11 by 2, we get 5 with a remainder of 1.
Put 5 as the next digit of the answer. 
Result so far: 125.0
Subtracting 10 from 11 leaves us with 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 2

Moving on to step 4:
19 divided by 2 is 9 with a remainder of 1.
The next digit of our result is 9. 
Result so far: 1259.0
Subtract 18 from 19 to get 1.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 2

Advancing to step 5:
If we divide 14 by 2, we get 7 and a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 12597.0
If we take 14 away from 14, we end up with 0.
Bring next digit (7) of the dividend behind the 0 and repeat the process: 7 / 2

Step 6:
When dividing 7 by 2, we get 3 with a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 125973.0
Subtracting 6 from 7 leaves us 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.

Moving on to step 7:
When dividing 10 by 2, we get 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 125973.5
Subtract 10 from 10 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.

On to step 8:
2 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 125973.5
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 9:
0 divided by 2 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 125973.5
If we subtract 0 from 0, we 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 125973.5 with a remainder of 0.0.
