We're dividing 70836403 by 724 
The aim is to understand the frequency of 724 in 70836403.

Let's proceed to step 1:
724 can be fit into 7 0 times, resulting in a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (0) from the dividend and append it to 7, then repeat: 70 / 724

Moving on to step 2:
70 divided by 724 is 0 with a remainder of 70.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 70, we end up with 70.
Take the next digit (8) from the dividend and append it to 70, then repeat: 708 / 724

Step 3:
708 divided by 724 is 0 with a remainder of 708.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 708 to get 708.
Include the next digit (3) from the dividend after 708, then repeat: 7083 / 724

On to step 4:
724 can be fit into 7083 9 times, resulting in a remainder of 567.
The next digit of our result is 9. 
Result so far: 9.0
If we subtract 6516 from 7083, we get 567.
Include the next digit (6) from the dividend after 567, then repeat: 5676 / 724

Let's proceed to step 5:
724 goes into 5676 7 times with a remainder of 608.
Write down 7 as next digit of the result. 
Result so far: 97.0
If we take 5068 away from 5676, we end up with 608.
Take the next digit (4) from the dividend and append it to 608, then repeat: 6084 / 724

Going ahead to step 6:
If we divide 6084 by 724, we get 8 and a remainder of 292.
Put 8 as the next digit of the answer. 
Result so far: 978.0
Subtract 5792 from 6084 to get 292.
Fetch the next digit (0) from the dividend, attach it to 292 and continue: 2920 / 724

Step 7:
2920 divided by 724 is 4 with a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 9784.0
The remainder is 24 after subtracting 2896 from 2920.
Grab the next digit (3) from the dividend, add it to 24, then carry on: 243 / 724

Step 8:
The number 724 fits into 243 0 times, leaving a remainder of 243.
The next digit of our result is 0. 
Result so far: 97840.0
The remainder is 243 after subtracting 0 from 243.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2430, and continue the process.

On to step 9:
If we divide 2430 by 724, we get 3 and a remainder of 258.
Use 3 as the next digit of our solution. 
Result so far: 97840.3
Subtract 2172 from 2430 to get 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Let's proceed to step 10:
724 can be fit into 2580 3 times, resulting in a remainder of 408.
Put 3 as the next digit of the answer. 
Result so far: 97840.33
If we take 2172 away from 2580, we end up with 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

After the division, we end up with 97840.33 and a remainder of 0.408.
