We're dividing 737486 by 1 
The aim is to understand the frequency of 1 in 737486.

Let's proceed to step 1:
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: 7.0
If we subtract 7 from 7, we get 0.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 1

Let's proceed to step 2:
1 goes into 3 3 times with a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 73.0
Subtract 3 from 3 to get 0.
Grab the next digit (7) from the dividend, add it to 0, then carry on: 7 / 1

Advancing to step 3:
1 can be fit into 7 7 times, resulting in a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 737.0
Deduct 7 from 7 and we're left with 0.
Bring next digit (4) of the dividend behind the 0 and repeat the process: 4 / 1

Moving on to step 4:
1 goes into 4 4 times with a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 7374.0
Subtract 4 from 4 to get 0.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 1

On to step 5:
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: 73748.0
Subtracting 8 from 8 leaves us with 0.
Bring next digit (6) of the dividend behind the 0 and repeat the process: 6 / 1

Step 6:
6 divided by 1 is 6 with a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 737486.0
If we take 6 away from 6, 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.

Going ahead to 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: 737486.0
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.

Advancing to step 8:
0 divided by 1 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 737486.0
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.

The final outcome is 737486.0, with a leftover of 0.0.
