We're dividing 55646647 by 724 
The aim is to understand the frequency of 724 in 55646647.

Step 1:
5 divided by 724 is 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 724

Going ahead to step 2:
724 can be fit into 55 0 times, resulting in a remainder of 55.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 55 and we're left with 55.
Fetch the next digit (6) from the dividend, attach it to 55 and continue: 556 / 724

Going ahead to step 3:
If we divide 556 by 724, we get 0 and a remainder of 556.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 556 to get 556.
Take the next digit (4) from the dividend and append it to 556, then repeat: 5564 / 724

Going ahead to step 4:
5564 divided by 724 is 7 with a remainder of 496.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we take 5068 away from 5564, we end up with 496.
Append the next digit (6) from the dividend to 496 and continue with: 4966 / 724

Advancing to step 5:
4966 divided by 724 is 6 with a remainder of 622.
Use 6 as the next digit of our solution. 
Result so far: 76.0
Subtract 4344 from 4966 to get 622.
Include the next digit (6) from the dividend after 622, then repeat: 6226 / 724

Moving on to step 6:
If we divide 6226 by 724, we get 8 and a remainder of 434.
Write down 8 as next digit of the result. 
Result so far: 768.0
Subtract 5792 from 6226 to get 434.
Append the next digit (4) from the dividend to 434 and continue with: 4344 / 724

Advancing to step 7:
4344 divided by 724 is 6 with a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 7686.0
Subtract 4344 from 4344 to get 0.
Take the next digit (7) from the dividend and append it to 0, then repeat: 7 / 724

Going ahead to step 8:
When dividing 7 by 724, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 76860.0
If we take 0 away from 7, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 9:
If we divide 70 by 724, we get 0 and a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 76860.0
Deduct 0 from 70 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 10:
The number 724 fits into 700 0 times, leaving a remainder of 700.
The number 0 becomes the next digit in our result. 
Result so far: 76860.0
Deduct 0 from 700 and we're left with 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

After the division, we end up with 76860.0 and a remainder of 0.7.
