916414 divided by 81 
The aim is to understand the frequency of 81 in 916414.

Step 1:
9 divided by 81 is 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Fetch the next digit (1) from the dividend, attach it to 9 and continue: 91 / 81

Step 2:
The number 81 fits into 91 1 times, leaving a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 10 after subtracting 81 from 91.
Grab the next digit (6) from the dividend, add it to 10, then carry on: 106 / 81

Moving on to step 3:
106 divided by 81 is 1 with a remainder of 25.
Use 1 as the next digit of our solution. 
Result so far: 11.0
If we take 81 away from 106, we end up with 25.
Bring next digit (4) of the dividend behind the 25 and repeat the process: 254 / 81

Moving on to step 4:
81 can be fit into 254 3 times, resulting in a remainder of 11.
The number 3 becomes the next digit in our result. 
Result so far: 113.0
Subtracting 243 from 254 leaves us with 11.
Fetch the next digit (1) from the dividend, attach it to 11 and continue: 111 / 81

Let's proceed to step 5:
81 can be fit into 111 1 times, resulting in a remainder of 30.
Put 1 as the next digit of the answer. 
Result so far: 1131.0
Subtract 81 from 111 to get 30.
Take the next digit (4) from the dividend and append it to 30, then repeat: 304 / 81

Let's proceed to step 6:
304 divided by 81 is 3 with a remainder of 61.
Record the quotient 3 as the next digit in the result. 
Result so far: 11313.0
Subtracting 243 from 304 leaves us with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Step 7:
The number 81 fits into 610 7 times, leaving a remainder of 43.
The next digit of our result is 7. 
Result so far: 11313.7
The remainder is 43 after subtracting 567 from 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

On to step 8:
The number 81 fits into 430 5 times, leaving a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 11313.75
If we take 405 away from 430, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 9:
81 can be fit into 250 3 times, resulting in a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 11313.753
The remainder is 7 after subtracting 243 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 10:
If we divide 70 by 81, we get 0 and a remainder of 70.
Use 0 as the next digit of our solution. 
Result so far: 11313.753
Subtract 0 from 70 to 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.

Let's proceed to step 11:
When dividing 700 by 81, we get 8 with a remainder of 52.
Record the quotient 8 as the next digit in the result. 
Result so far: 11313.75308
If we take 648 away from 700, we end up 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.

Going ahead to step 12:
81 can be fit into 520 6 times, resulting in a remainder of 34.
Write down 6 as next digit of the result. 
Result so far: 11313.753086
Subtracting 486 from 520 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.

On to step 13:
The number 81 fits into 340 4 times, leaving a remainder of 16.
The next digit of our result is 4. 
Result so far: 11313.7530864
If we subtract 324 from 340, we 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.

Moving on to step 14:
When dividing 160 by 81, we get 1 with a remainder of 79.
Record the quotient 1 as the next digit in the result. 
Result so far: 11313.75308641
If we subtract 81 from 160, we get 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

The quotient of the division is 11313.75308641, and the remainder is 7.9e-08.
