371886 ÷ 2 
The aim is to understand the frequency of 2 in 371886.

On to step 1:
The number 2 fits into 3 1 times, leaving a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 1 after subtracting 2 from 3.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 2

Advancing to step 2:
When dividing 17 by 2, we get 8 with a remainder of 1.
Put 8 as the next digit of the answer. 
Result so far: 18.0
Deduct 16 from 17 and we're left with 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 2

Let's proceed to step 3:
When dividing 11 by 2, we get 5 with a remainder of 1.
The next digit of our result is 5. 
Result so far: 185.0
Deduct 10 from 11 and we're left with 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 2

Moving on to step 4:
2 can be fit into 18 9 times, resulting in a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 1859.0
If we subtract 18 from 18, we get 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 2

On to step 5:
When dividing 8 by 2, we get 4 with a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 18594.0
Subtracting 8 from 8 leaves us with 0.
Append the next digit (6) from the dividend to 0 and continue with: 6 / 2

On to step 6:
2 can be fit into 6 3 times, resulting in a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 185943.0
Subtracting 6 from 6 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.

Let's proceed to step 7:
2 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 185943.0
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 8:
0 divided by 2 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 185943.0
Deduct 0 from 0 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.

The final result is 185943.0 with a remainder of 0.0.
