We look at the division of 428123 by 93 
The aim is to understand the frequency of 93 in 428123.

Advancing to step 1:
93 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 93

Advancing to step 2:
93 can be fit into 42 0 times, resulting in a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 42, we get 42.
Append the next digit (8) from the dividend to 42 and continue with: 428 / 93

Advancing to step 3:
If we divide 428 by 93, we get 4 and a remainder of 56.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtracting 372 from 428 leaves us with 56.
Fetch the next digit (1) from the dividend, attach it to 56 and continue: 561 / 93

Advancing to step 4:
When dividing 561 by 93, we get 6 with a remainder of 3.
The next digit of our result is 6. 
Result so far: 46.0
The remainder is 3 after subtracting 558 from 561.
Take the next digit (2) from the dividend and append it to 3, then repeat: 32 / 93

Moving on to step 5:
When dividing 32 by 93, we get 0 with a remainder of 32.
Put 0 as the next digit of the answer. 
Result so far: 460.0
If we subtract 0 from 32, we get 32.
Grab the next digit (3) from the dividend, add it to 32, then carry on: 323 / 93

Advancing to step 6:
The number 93 fits into 323 3 times, leaving a remainder of 44.
Use 3 as the next digit of our solution. 
Result so far: 4603.0
If we subtract 279 from 323, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 7:
440 divided by 93 is 4 with a remainder of 68.
Use 4 as the next digit of our solution. 
Result so far: 4603.4
Subtract 372 from 440 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 8:
If we divide 680 by 93, we get 7 and a remainder of 29.
Write down 7 as next digit of the result. 
Result so far: 4603.47
Deduct 651 from 680 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Moving on to step 9:
When dividing 290 by 93, we get 3 with a remainder of 11.
Write down 3 as next digit of the result. 
Result so far: 4603.473
Subtracting 279 from 290 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 10:
93 goes into 110 1 times with a remainder of 17.
Write down 1 as next digit of the result. 
Result so far: 4603.4731
Subtracting 93 from 110 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 11:
When dividing 170 by 93, we get 1 with a remainder of 77.
Write down 1 as next digit of the result. 
Result so far: 4603.47311
If we subtract 93 from 170, we get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

After the division, we end up with 4603.47311 and a remainder of 7.7e-05.
