We look at the division of 812171 by 94 
The aim is to understand the frequency of 94 in 812171.

Advancing to step 1:
The number 94 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 94

Moving on to step 2:
The number 94 fits into 81 0 times, leaving a remainder of 81.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 81 after subtracting 0 from 81.
Include the next digit (2) from the dividend after 81, then repeat: 812 / 94

Advancing to step 3:
If we divide 812 by 94, we get 8 and a remainder of 60.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Deduct 752 from 812 and we're left with 60.
Append the next digit (1) from the dividend to 60 and continue with: 601 / 94

Going ahead to step 4:
601 divided by 94 is 6 with a remainder of 37.
Record the quotient 6 as the next digit in the result. 
Result so far: 86.0
If we take 564 away from 601, we end up with 37.
Take the next digit (7) from the dividend and append it to 37, then repeat: 377 / 94

On to step 5:
If we divide 377 by 94, we get 4 and a remainder of 1.
The next digit of our result is 4. 
Result so far: 864.0
The remainder is 1 after subtracting 376 from 377.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 94

Going ahead to step 6:
94 can be fit into 11 0 times, resulting in a remainder of 11.
Use 0 as the next digit of our solution. 
Result so far: 8640.0
If we take 0 away from 11, we end up 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.

Advancing to step 7:
94 can be fit into 110 1 times, resulting in a remainder of 16.
The next digit of our result is 1. 
Result so far: 8640.1
Subtract 94 from 110 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 8:
When dividing 160 by 94, we get 1 with a remainder of 66.
Put 1 as the next digit of the answer. 
Result so far: 8640.11
Deduct 94 from 160 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

The final outcome is 8640.11, with a leftover of 0.066.
