Let's divide 61739 by 1
The aim is to understand the frequency of 1 in 61739.

Advancing to step 1:
6 divided by 1 is 6 with a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Deduct 6 from 6 and we're left with 0.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 1

Step 2:
If we divide 1 by 1, we get 1 and a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 61.0
If we take 1 away from 1, we end up with 0.
Include the next digit (7) from the dividend after 0, then repeat: 7 / 1

Step 3:
When dividing 7 by 1, we get 7 with a remainder of 0.
The next digit of our result is 7. 
Result so far: 617.0
Subtract 7 from 7 to get 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 1

On to step 4:
1 can be fit into 3 3 times, resulting in a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 6173.0
If we subtract 3 from 3, we get 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 1

On to step 5:
9 divided by 1 is 9 with a remainder of 0.
Use 9 as the next digit of our solution. 
Result so far: 61739.0
If we subtract 9 from 9, 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.

Advancing to step 6:
If we divide 0 by 1, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 61739.0
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.

On to step 7:
0 divided by 1 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 61739.0
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.

Our division results in 61739.0 with a remaining 0.0.
