We look at the division of 75121 by 94 
The aim is to understand the frequency of 94 in 75121.

Going ahead to step 1:
When dividing 7 by 94, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (5) from the dividend, add it to 7, then carry on: 75 / 94

Step 2:
94 can be fit into 75 0 times, resulting in a remainder of 75.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 75 after subtracting 0 from 75.
Fetch the next digit (1) from the dividend, attach it to 75 and continue: 751 / 94

Advancing to step 3:
94 can be fit into 751 7 times, resulting in a remainder of 93.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Deduct 658 from 751 and we're left with 93.
Fetch the next digit (2) from the dividend, attach it to 93 and continue: 932 / 94

On to step 4:
932 divided by 94 is 9 with a remainder of 86.
Put 9 as the next digit of the answer. 
Result so far: 79.0
If we take 846 away from 932, we end up with 86.
Take the next digit (1) from the dividend and append it to 86, then repeat: 861 / 94

Going ahead to step 5:
94 goes into 861 9 times with a remainder of 15.
The next digit of our result is 9. 
Result so far: 799.0
If we subtract 846 from 861, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 6:
94 can be fit into 150 1 times, resulting in a remainder of 56.
The number 1 becomes the next digit in our result. 
Result so far: 799.1
If we take 94 away from 150, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 7:
560 divided by 94 is 5 with a remainder of 90.
Record the quotient 5 as the next digit in the result. 
Result so far: 799.15
Deduct 470 from 560 and we're left with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Let's proceed to step 8:
900 divided by 94 is 9 with a remainder of 54.
Use 9 as the next digit of our solution. 
Result so far: 799.159
If we take 846 away from 900, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 9:
When dividing 540 by 94, we get 5 with a remainder of 70.
The next digit of our result is 5. 
Result so far: 799.1595
If we subtract 470 from 540, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 10:
When dividing 700 by 94, we get 7 with a remainder of 42.
The next digit of our result is 7. 
Result so far: 799.15957
The remainder is 42 after subtracting 658 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 11:
When dividing 420 by 94, we get 4 with a remainder of 44.
Use 4 as the next digit of our solution. 
Result so far: 799.159574
Deduct 376 from 420 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 12:
94 goes into 440 4 times with a remainder of 64.
The number 4 becomes the next digit in our result. 
Result so far: 799.1595744
Deduct 376 from 440 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The final outcome is 799.1595744, with a leftover of 6.4e-07.
