We divide 941640 by 1
The aim is to understand the frequency of 1 in 941640.

Going ahead to step 1:
The number 1 fits into 9 9 times, leaving a remainder of 0.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we take 9 away from 9, we end up with 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 1

Let's proceed to step 2:
1 can be fit into 4 4 times, resulting in a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 94.0
Deduct 4 from 4 and we're left with 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 1

Let's proceed to step 3:
1 goes into 1 1 times with a remainder of 0.
The next digit of our result is 1. 
Result so far: 941.0
Subtract 1 from 1 to get 0.
Fetch the next digit (6) from the dividend, attach it to 0 and continue: 6 / 1

Advancing to step 4:
If we divide 6 by 1, we get 6 and a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 9416.0
If we subtract 6 from 6, we get 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 1

Moving on to step 5:
When dividing 4 by 1, we get 4 with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 94164.0
If we subtract 4 from 4, we get 0.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 1

Let's proceed to step 6:
If we divide 0 by 1, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 941640.0
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.

Let's proceed to step 7:
The number 1 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 941640.0
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.

Advancing to step 8:
1 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 941640.0
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 941640.0 and a remainder of 0.0.
