We look at the division of 9011435 by 724 
The aim is to understand the frequency of 724 in 9011435.

Let's proceed to step 1:
724 goes into 9 0 times with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 724

On to step 2:
When dividing 90 by 724, we get 0 with a remainder of 90.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 90 after subtracting 0 from 90.
Include the next digit (1) from the dividend after 90, then repeat: 901 / 724

Going ahead to step 3:
901 divided by 724 is 1 with a remainder of 177.
The next digit of our result is 1. 
Result so far: 1.0
If we take 724 away from 901, we end up with 177.
Bring next digit (1) of the dividend behind the 177 and repeat the process: 1771 / 724

Advancing to step 4:
The number 724 fits into 1771 2 times, leaving a remainder of 323.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Subtracting 1448 from 1771 leaves us with 323.
Append the next digit (4) from the dividend to 323 and continue with: 3234 / 724

Step 5:
When dividing 3234 by 724, we get 4 with a remainder of 338.
Use 4 as the next digit of our solution. 
Result so far: 124.0
Deduct 2896 from 3234 and we're left with 338.
Bring next digit (3) of the dividend behind the 338 and repeat the process: 3383 / 724

Going ahead to step 6:
3383 divided by 724 is 4 with a remainder of 487.
Record the quotient 4 as the next digit in the result. 
Result so far: 1244.0
Subtracting 2896 from 3383 leaves us with 487.
Append the next digit (5) from the dividend to 487 and continue with: 4875 / 724

Moving on to step 7:
If we divide 4875 by 724, we get 6 and a remainder of 531.
Write down 6 as next digit of the result. 
Result so far: 12446.0
If we subtract 4344 from 4875, we get 531.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5310, and continue the process.

Advancing to step 8:
724 can be fit into 5310 7 times, resulting in a remainder of 242.
Write down 7 as next digit of the result. 
Result so far: 12446.7
If we subtract 5068 from 5310, we get 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

Advancing to step 9:
2420 divided by 724 is 3 with a remainder of 248.
Record the quotient 3 as the next digit in the result. 
Result so far: 12446.73
Deduct 2172 from 2420 and we're left with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Moving on to step 10:
The number 724 fits into 2480 3 times, leaving a remainder of 308.
Write down 3 as next digit of the result. 
Result so far: 12446.733
Subtract 2172 from 2480 to get 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

The quotient of the division is 12446.733, and the remainder is 0.0308.
