1887990 divided by 2 
The aim is to understand the frequency of 2 in 1887990.

On to step 1:
2 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 2

Advancing to step 2:
When dividing 18 by 2, we get 9 with a remainder of 0.
The next digit of our result is 9. 
Result so far: 9.0
Deduct 18 from 18 and we're left with 0.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 2

Advancing to step 3:
8 divided by 2 is 4 with a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 94.0
If we take 8 away from 8, we end up with 0.
Take the next digit (7) from the dividend and append it to 0, then repeat: 7 / 2

Let's proceed to step 4:
2 can be fit into 7 3 times, resulting in a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 943.0
The remainder is 1 after subtracting 6 from 7.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 2

Advancing to step 5:
2 can be fit into 19 9 times, resulting in a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 9439.0
If we subtract 18 from 19, we get 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 2

Advancing to step 6:
The number 2 fits into 19 9 times, leaving a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 94399.0
If we subtract 18 from 19, we get 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 2

Let's proceed to step 7:
The number 2 fits into 10 5 times, leaving a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 943995.0
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 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 943995.0
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.

On to step 9:
2 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 943995.0
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.

After the division, we end up with 943995.0 and a remainder of 0.0.
