210128 divided by 1 
The aim is to understand the frequency of 1 in 210128.

Moving on to step 1:
If we divide 2 by 1, we get 2 and a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 0 after subtracting 2 from 2.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 1

On to step 2:
If we divide 1 by 1, we get 1 and a remainder of 0.
The next digit of our result is 1. 
Result so far: 21.0
If we subtract 1 from 1, we get 0.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 1

Advancing to step 3:
0 divided by 1 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 210.0
If we subtract 0 from 0, we get 0.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 1

Going ahead to step 4:
1 goes into 1 1 times with a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 2101.0
Subtract 1 from 1 to get 0.
Include the next digit (2) from the dividend after 0, then repeat: 2 / 1

Step 5:
2 divided by 1 is 2 with a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 21012.0
Subtract 2 from 2 to get 0.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 1

Step 6:
If we divide 8 by 1, we get 8 and a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 210128.0
Subtract 8 from 8 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.

Step 7:
If we divide 0 by 1, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 210128.0
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.

Let's proceed to step 8:
When dividing 0 by 1, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 210128.0
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 quotient of the division is 210128.0, and the remainder is 0.0.
