We're dividing 3578553 by 744 
The aim is to understand the frequency of 744 in 3578553.

On to step 1:
744 goes into 3 0 times with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (5) from the dividend and append it to 3, then repeat: 35 / 744

Advancing to step 2:
744 goes into 35 0 times with a remainder of 35.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 35 leaves us with 35.
Take the next digit (7) from the dividend and append it to 35, then repeat: 357 / 744

Step 3:
744 can be fit into 357 0 times, resulting in a remainder of 357.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 357 leaves us with 357.
Fetch the next digit (8) from the dividend, attach it to 357 and continue: 3578 / 744

Step 4:
The number 744 fits into 3578 4 times, leaving a remainder of 602.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 602 after subtracting 2976 from 3578.
Grab the next digit (5) from the dividend, add it to 602, then carry on: 6025 / 744

Step 5:
744 can be fit into 6025 8 times, resulting in a remainder of 73.
The number 8 becomes the next digit in our result. 
Result so far: 48.0
If we subtract 5952 from 6025, we get 73.
Append the next digit (5) from the dividend to 73 and continue with: 735 / 744

Let's proceed to step 6:
735 divided by 744 is 0 with a remainder of 735.
Record the quotient 0 as the next digit in the result. 
Result so far: 480.0
If we take 0 away from 735, we end up with 735.
Take the next digit (3) from the dividend and append it to 735, then repeat: 7353 / 744

Advancing to step 7:
7353 divided by 744 is 9 with a remainder of 657.
Write down 9 as next digit of the result. 
Result so far: 4809.0
If we take 6696 away from 7353, we end up with 657.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6570, and continue the process.

On to step 8:
6570 divided by 744 is 8 with a remainder of 618.
The next digit of our result is 8. 
Result so far: 4809.8
Subtracting 5952 from 6570 leaves us with 618.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6180, and continue the process.

Advancing to step 9:
If we divide 6180 by 744, we get 8 and a remainder of 228.
Write down 8 as next digit of the result. 
Result so far: 4809.88
If we take 5952 away from 6180, we end up with 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

The quotient of the division is 4809.88, and the remainder is 0.228.
