55669609 divided by 1 
The aim is to understand the frequency of 1 in 55669609.

Advancing to step 1:
1 can be fit into 5 5 times, resulting in a remainder of 0.
The next digit of our result is 5. 
Result so far: 5.0
If we subtract 5 from 5, we get 0.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 1

Moving on to step 2:
1 goes into 5 5 times with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 55.0
Subtract 5 from 5 to get 0.
Include the next digit (6) from the dividend after 0, then repeat: 6 / 1

Advancing to step 3:
The number 1 fits into 6 6 times, leaving a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 556.0
Deduct 6 from 6 and we're left with 0.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 1

Advancing to step 4:
1 goes into 6 6 times with a remainder of 0.
The next digit of our result is 6. 
Result so far: 5566.0
The remainder is 0 after subtracting 6 from 6.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 1

Step 5:
If we divide 9 by 1, we get 9 and a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 55669.0
Subtract 9 from 9 to get 0.
Bring next digit (6) of the dividend behind the 0 and repeat the process: 6 / 1

Advancing to step 6:
When dividing 6 by 1, we get 6 with a remainder of 0.
The next digit of our result is 6. 
Result so far: 556696.0
The remainder is 0 after subtracting 6 from 6.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 1

Going ahead to step 7:
0 divided by 1 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 5566960.0
Subtracting 0 from 0 leaves us with 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 1

Moving on to step 8:
If we divide 9 by 1, we get 9 and a remainder of 0.
The next digit of our result is 9. 
Result so far: 55669609.0
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.

On to step 9:
0 divided by 1 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 55669609.0
Deduct 0 from 0 and we're left 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 10:
0 divided by 1 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 55669609.0
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.

The quotient of the division is 55669609.0, and the remainder is 0.0.
