Let's divide 74238001 by 553
The aim is to understand the frequency of 553 in 74238001.

Advancing to step 1:
When dividing 7 by 553, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (4) from the dividend, add it to 7, then carry on: 74 / 553

Moving on to step 2:
The number 553 fits into 74 0 times, leaving a remainder of 74.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 74 after subtracting 0 from 74.
Append the next digit (2) from the dividend to 74 and continue with: 742 / 553

Going ahead to step 3:
553 goes into 742 1 times with a remainder of 189.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 553 from 742, we get 189.
Fetch the next digit (3) from the dividend, attach it to 189 and continue: 1893 / 553

Moving on to step 4:
The number 553 fits into 1893 3 times, leaving a remainder of 234.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Deduct 1659 from 1893 and we're left with 234.
Fetch the next digit (8) from the dividend, attach it to 234 and continue: 2348 / 553

Moving on to step 5:
2348 divided by 553 is 4 with a remainder of 136.
Record the quotient 4 as the next digit in the result. 
Result so far: 134.0
Subtract 2212 from 2348 to get 136.
Grab the next digit (0) from the dividend, add it to 136, then carry on: 1360 / 553

Step 6:
553 can be fit into 1360 2 times, resulting in a remainder of 254.
Use 2 as the next digit of our solution. 
Result so far: 1342.0
If we subtract 1106 from 1360, we get 254.
Append the next digit (0) from the dividend to 254 and continue with: 2540 / 553

Moving on to step 7:
The number 553 fits into 2540 4 times, leaving a remainder of 328.
Put 4 as the next digit of the answer. 
Result so far: 13424.0
Subtracting 2212 from 2540 leaves us with 328.
Include the next digit (1) from the dividend after 328, then repeat: 3281 / 553

On to step 8:
When dividing 3281 by 553, we get 5 with a remainder of 516.
The number 5 becomes the next digit in our result. 
Result so far: 134245.0
Subtracting 2765 from 3281 leaves us with 516.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5160, and continue the process.

Let's proceed to step 9:
5160 divided by 553 is 9 with a remainder of 183.
The number 9 becomes the next digit in our result. 
Result so far: 134245.9
If we take 4977 away from 5160, we end up with 183.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1830, and continue the process.

Going ahead to step 10:
553 can be fit into 1830 3 times, resulting in a remainder of 171.
Use 3 as the next digit of our solution. 
Result so far: 134245.93
If we take 1659 away from 1830, we end up with 171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

Advancing to step 11:
1710 divided by 553 is 3 with a remainder of 51.
Put 3 as the next digit of the answer. 
Result so far: 134245.933
Subtract 1659 from 1710 to get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Our division results in 134245.933 with a remaining 0.0051.
