Let's divide 941292 by 81
The aim is to understand the frequency of 81 in 941292.

Advancing to step 1:
81 goes into 9 0 times with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Append the next digit (4) from the dividend to 9 and continue with: 94 / 81

Advancing to step 2:
94 divided by 81 is 1 with a remainder of 13.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 81 from 94 to get 13.
Include the next digit (1) from the dividend after 13, then repeat: 131 / 81

Advancing to step 3:
When dividing 131 by 81, we get 1 with a remainder of 50.
The next digit of our result is 1. 
Result so far: 11.0
Subtract 81 from 131 to get 50.
Include the next digit (2) from the dividend after 50, then repeat: 502 / 81

Going ahead to step 4:
When dividing 502 by 81, we get 6 with a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 116.0
Deduct 486 from 502 and we're left with 16.
Bring next digit (9) of the dividend behind the 16 and repeat the process: 169 / 81

Going ahead to step 5:
The number 81 fits into 169 2 times, leaving a remainder of 7.
The number 2 becomes the next digit in our result. 
Result so far: 1162.0
Deduct 162 from 169 and we're left with 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 81

On to step 6:
The number 81 fits into 72 0 times, leaving a remainder of 72.
Put 0 as the next digit of the answer. 
Result so far: 11620.0
Subtract 0 from 72 to 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 7:
81 can be fit into 720 8 times, resulting in a remainder of 72.
Record the quotient 8 as the next digit in the result. 
Result so far: 11620.8
Subtract 648 from 720 to 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.

Going ahead to step 8:
720 divided by 81 is 8 with a remainder of 72.
Put 8 as the next digit of the answer. 
Result so far: 11620.88
Subtract 648 from 720 to 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.

Our division results in 11620.88 with a remaining 0.072.
