We look at the division of 437890 by 93 
The aim is to understand the frequency of 93 in 437890.

Advancing to step 1:
If we divide 4 by 93, we get 0 and a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 93

Let's proceed to step 2:
When dividing 43 by 93, we get 0 with a remainder of 43.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 43, we get 43.
Append the next digit (7) from the dividend to 43 and continue with: 437 / 93

Step 3:
When dividing 437 by 93, we get 4 with a remainder of 65.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 372 from 437, we get 65.
Append the next digit (8) from the dividend to 65 and continue with: 658 / 93

On to step 4:
93 can be fit into 658 7 times, resulting in a remainder of 7.
The number 7 becomes the next digit in our result. 
Result so far: 47.0
If we take 651 away from 658, we end up with 7.
Include the next digit (9) from the dividend after 7, then repeat: 79 / 93

Going ahead to step 5:
When dividing 79 by 93, we get 0 with a remainder of 79.
The next digit of our result is 0. 
Result so far: 470.0
Deduct 0 from 79 and we're left with 79.
Grab the next digit (0) from the dividend, add it to 79, then carry on: 790 / 93

Moving on to step 6:
When dividing 790 by 93, we get 8 with a remainder of 46.
Put 8 as the next digit of the answer. 
Result so far: 4708.0
If we take 744 away from 790, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 7:
The number 93 fits into 460 4 times, leaving a remainder of 88.
Put 4 as the next digit of the answer. 
Result so far: 4708.4
If we take 372 away from 460, we end up with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Going ahead to step 8:
If we divide 880 by 93, we get 9 and a remainder of 43.
Record the quotient 9 as the next digit in the result. 
Result so far: 4708.49
If we subtract 837 from 880, we get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Advancing to step 9:
430 divided by 93 is 4 with a remainder of 58.
The number 4 becomes the next digit in our result. 
Result so far: 4708.494
If we subtract 372 from 430, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Going ahead to step 10:
580 divided by 93 is 6 with a remainder of 22.
Write down 6 as next digit of the result. 
Result so far: 4708.4946
If we subtract 558 from 580, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 11:
220 divided by 93 is 2 with a remainder of 34.
Use 2 as the next digit of our solution. 
Result so far: 4708.49462
Subtracting 186 from 220 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 12:
The number 93 fits into 340 3 times, leaving a remainder of 61.
Use 3 as the next digit of our solution. 
Result so far: 4708.494623
If we subtract 279 from 340, we get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Advancing to step 13:
610 divided by 93 is 6 with a remainder of 52.
Write down 6 as next digit of the result. 
Result so far: 4708.4946236
Subtracting 558 from 610 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 14:
If we divide 520 by 93, we get 5 and a remainder of 55.
Record the quotient 5 as the next digit in the result. 
Result so far: 4708.49462365
The remainder is 55 after subtracting 465 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

After the division, we end up with 4708.49462365 and a remainder of 5.5e-08.
