We divide 116976 by 81
The aim is to understand the frequency of 81 in 116976.

Let's proceed to step 1:
81 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Grab the next digit (1) from the dividend, add it to 1, then carry on: 11 / 81

Advancing to step 2:
When dividing 11 by 81, we get 0 with a remainder of 11.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 11, we get 11.
Bring next digit (6) of the dividend behind the 11 and repeat the process: 116 / 81

Advancing to step 3:
81 can be fit into 116 1 times, resulting in a remainder of 35.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 35 after subtracting 81 from 116.
Include the next digit (9) from the dividend after 35, then repeat: 359 / 81

On to step 4:
81 can be fit into 359 4 times, resulting in a remainder of 35.
Use 4 as the next digit of our solution. 
Result so far: 14.0
If we subtract 324 from 359, we get 35.
Fetch the next digit (7) from the dividend, attach it to 35 and continue: 357 / 81

Moving on to step 5:
357 divided by 81 is 4 with a remainder of 33.
Use 4 as the next digit of our solution. 
Result so far: 144.0
Subtracting 324 from 357 leaves us with 33.
Take the next digit (6) from the dividend and append it to 33, then repeat: 336 / 81

Moving on to step 6:
The number 81 fits into 336 4 times, leaving a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 1444.0
If we take 324 away from 336, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 7:
120 divided by 81 is 1 with a remainder of 39.
The next digit of our result is 1. 
Result so far: 1444.1
If we take 81 away from 120, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Going ahead to step 8:
If we divide 390 by 81, we get 4 and a remainder of 66.
The number 4 becomes the next digit in our result. 
Result so far: 1444.14
The remainder is 66 after subtracting 324 from 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 9:
81 can be fit into 660 8 times, resulting in a remainder of 12.
The next digit of our result is 8. 
Result so far: 1444.148
If we subtract 648 from 660, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 10:
81 goes into 120 1 times with a remainder of 39.
Use 1 as the next digit of our solution. 
Result so far: 1444.1481
If we take 81 away from 120, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Advancing to step 11:
81 can be fit into 390 4 times, resulting in a remainder of 66.
The number 4 becomes the next digit in our result. 
Result so far: 1444.14814
If we subtract 324 from 390, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Going ahead to step 12:
If we divide 660 by 81, we get 8 and a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 1444.148148
Subtracting 648 from 660 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 13:
81 goes into 120 1 times with a remainder of 39.
The number 1 becomes the next digit in our result. 
Result so far: 1444.1481481
If we take 81 away from 120, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Let's proceed to step 14:
When dividing 390 by 81, we get 4 with a remainder of 66.
Use 4 as the next digit of our solution. 
Result so far: 1444.14814814
Subtract 324 from 390 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Our division results in 1444.14814814 with a remaining 6.6e-08.
