We're dividing 397545 by 93 
The aim is to understand the frequency of 93 in 397545.

Going ahead to step 1:
If we divide 3 by 93, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 93

Advancing to step 2:
The number 93 fits into 39 0 times, leaving a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 39 after subtracting 0 from 39.
Bring next digit (7) of the dividend behind the 39 and repeat the process: 397 / 93

On to step 3:
If we divide 397 by 93, we get 4 and a remainder of 25.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
The remainder is 25 after subtracting 372 from 397.
Fetch the next digit (5) from the dividend, attach it to 25 and continue: 255 / 93

Advancing to step 4:
93 goes into 255 2 times with a remainder of 69.
The number 2 becomes the next digit in our result. 
Result so far: 42.0
If we take 186 away from 255, we end up with 69.
Fetch the next digit (4) from the dividend, attach it to 69 and continue: 694 / 93

On to step 5:
694 divided by 93 is 7 with a remainder of 43.
Write down 7 as next digit of the result. 
Result so far: 427.0
Subtracting 651 from 694 leaves us with 43.
Include the next digit (5) from the dividend after 43, then repeat: 435 / 93

Going ahead to step 6:
93 can be fit into 435 4 times, resulting in a remainder of 63.
Write down 4 as next digit of the result. 
Result so far: 4274.0
If we subtract 372 from 435, we get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Step 7:
93 can be fit into 630 6 times, resulting in a remainder of 72.
Record the quotient 6 as the next digit in the result. 
Result so far: 4274.6
If we subtract 558 from 630, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 8:
720 divided by 93 is 7 with a remainder of 69.
Write down 7 as next digit of the result. 
Result so far: 4274.67
Subtracting 651 from 720 leaves us with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

On to step 9:
93 can be fit into 690 7 times, resulting in a remainder of 39.
The next digit of our result is 7. 
Result so far: 4274.677
If we subtract 651 from 690, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

The quotient of the division is 4274.677, and the remainder is 0.0039.
