75334381 ÷ 437 
The aim is to understand the frequency of 437 in 75334381.

Let's proceed to step 1:
437 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (5) of the dividend behind the 7 and repeat the process: 75 / 437

Let's proceed to step 2:
If we divide 75 by 437, we get 0 and a remainder of 75.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 75, we get 75.
Fetch the next digit (3) from the dividend, attach it to 75 and continue: 753 / 437

Moving on to step 3:
437 can be fit into 753 1 times, resulting in a remainder of 316.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 437 from 753 to get 316.
Bring next digit (3) of the dividend behind the 316 and repeat the process: 3163 / 437

Step 4:
437 can be fit into 3163 7 times, resulting in a remainder of 104.
Use 7 as the next digit of our solution. 
Result so far: 17.0
If we subtract 3059 from 3163, we get 104.
Take the next digit (4) from the dividend and append it to 104, then repeat: 1044 / 437

On to step 5:
The number 437 fits into 1044 2 times, leaving a remainder of 170.
Use 2 as the next digit of our solution. 
Result so far: 172.0
If we subtract 874 from 1044, we get 170.
Take the next digit (3) from the dividend and append it to 170, then repeat: 1703 / 437

Advancing to step 6:
If we divide 1703 by 437, we get 3 and a remainder of 392.
Record the quotient 3 as the next digit in the result. 
Result so far: 1723.0
Subtracting 1311 from 1703 leaves us with 392.
Grab the next digit (8) from the dividend, add it to 392, then carry on: 3928 / 437

Advancing to step 7:
The number 437 fits into 3928 8 times, leaving a remainder of 432.
Use 8 as the next digit of our solution. 
Result so far: 17238.0
Deduct 3496 from 3928 and we're left with 432.
Bring next digit (1) of the dividend behind the 432 and repeat the process: 4321 / 437

Step 8:
437 goes into 4321 9 times with a remainder of 388.
Write down 9 as next digit of the result. 
Result so far: 172389.0
If we take 3933 away from 4321, we end up with 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Moving on to step 9:
437 can be fit into 3880 8 times, resulting in a remainder of 384.
Put 8 as the next digit of the answer. 
Result so far: 172389.8
Subtracting 3496 from 3880 leaves us with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Going ahead to step 10:
The number 437 fits into 3840 8 times, leaving a remainder of 344.
Record the quotient 8 as the next digit in the result. 
Result so far: 172389.88
Subtract 3496 from 3840 to get 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

The final outcome is 172389.88, with a leftover of 0.344.
