737126 ÷ 1 
The aim is to understand the frequency of 1 in 737126.

Let's proceed to step 1:
1 goes into 7 7 times with a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we take 7 away from 7, we end up with 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 1

Let's proceed to step 2:
When dividing 3 by 1, we get 3 with a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 73.0
Subtract 3 from 3 to get 0.
Append the next digit (7) from the dividend to 0 and continue with: 7 / 1

Going ahead to step 3:
The number 1 fits into 7 7 times, leaving a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 737.0
If we take 7 away from 7, we end up with 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 1

Moving on to step 4:
1 goes into 1 1 times with a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 7371.0
Subtract 1 from 1 to get 0.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 1

Moving on to step 5:
The number 1 fits into 2 2 times, leaving a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 73712.0
Deduct 2 from 2 and we're left with 0.
Fetch the next digit (6) from the dividend, attach it to 0 and continue: 6 / 1

On to step 6:
1 goes into 6 6 times with a remainder of 0.
The next digit of our result is 6. 
Result so far: 737126.0
If we subtract 6 from 6, 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.

Going ahead to step 7:
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: 737126.0
If we take 0 away from 0, we end up 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.

Step 8:
1 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 737126.0
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.

In conclusion, the division gives 737126.0 with a balance of 0.0.
