We look at the division of 33751521 by 739 
The aim is to understand the frequency of 739 in 33751521.

On to step 1:
739 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 take 0 away from 3, we end up with 3.
Include the next digit (3) from the dividend after 3, then repeat: 33 / 739

Step 2:
739 goes into 33 0 times with a remainder of 33.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 33 after subtracting 0 from 33.
Take the next digit (7) from the dividend and append it to 33, then repeat: 337 / 739

Step 3:
739 can be fit into 337 0 times, resulting in a remainder of 337.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 337 leaves us with 337.
Append the next digit (5) from the dividend to 337 and continue with: 3375 / 739

On to step 4:
739 goes into 3375 4 times with a remainder of 419.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we take 2956 away from 3375, we end up with 419.
Grab the next digit (1) from the dividend, add it to 419, then carry on: 4191 / 739

Advancing to step 5:
The number 739 fits into 4191 5 times, leaving a remainder of 496.
Put 5 as the next digit of the answer. 
Result so far: 45.0
If we take 3695 away from 4191, we end up with 496.
Grab the next digit (5) from the dividend, add it to 496, then carry on: 4965 / 739

Step 6:
739 goes into 4965 6 times with a remainder of 531.
The number 6 becomes the next digit in our result. 
Result so far: 456.0
Subtracting 4434 from 4965 leaves us with 531.
Fetch the next digit (2) from the dividend, attach it to 531 and continue: 5312 / 739

Step 7:
739 goes into 5312 7 times with a remainder of 139.
Write down 7 as next digit of the result. 
Result so far: 4567.0
The remainder is 139 after subtracting 5173 from 5312.
Append the next digit (1) from the dividend to 139 and continue with: 1391 / 739

Going ahead to step 8:
739 can be fit into 1391 1 times, resulting in a remainder of 652.
Write down 1 as next digit of the result. 
Result so far: 45671.0
If we take 739 away from 1391, we end up with 652.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6520, and continue the process.

Going ahead to step 9:
739 goes into 6520 8 times with a remainder of 608.
The number 8 becomes the next digit in our result. 
Result so far: 45671.8
If we subtract 5912 from 6520, we get 608.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6080, and continue the process.

Let's proceed to step 10:
When dividing 6080 by 739, we get 8 with a remainder of 168.
Put 8 as the next digit of the answer. 
Result so far: 45671.88
If we take 5912 away from 6080, we end up with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

The final result is 45671.88 with a remainder of 0.168.
