We divide 116359 by 81
The aim is to understand the frequency of 81 in 116359.

Moving on to step 1:
81 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 81

Step 2:
When dividing 11 by 81, we get 0 with a remainder of 11.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 11, we end up with 11.
Fetch the next digit (6) from the dividend, attach it to 11 and continue: 116 / 81

Step 3:
116 divided by 81 is 1 with a remainder of 35.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 81 from 116 leaves us with 35.
Append the next digit (3) from the dividend to 35 and continue with: 353 / 81

On to step 4:
If we divide 353 by 81, we get 4 and a remainder of 29.
The next digit of our result is 4. 
Result so far: 14.0
If we subtract 324 from 353, we get 29.
Append the next digit (5) from the dividend to 29 and continue with: 295 / 81

Let's proceed to step 5:
When dividing 295 by 81, we get 3 with a remainder of 52.
Put 3 as the next digit of the answer. 
Result so far: 143.0
If we take 243 away from 295, we end up with 52.
Take the next digit (9) from the dividend and append it to 52, then repeat: 529 / 81

Step 6:
When dividing 529 by 81, we get 6 with a remainder of 43.
The next digit of our result is 6. 
Result so far: 1436.0
Deduct 486 from 529 and we're left with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Advancing to step 7:
The number 81 fits into 430 5 times, leaving a remainder of 25.
The next digit of our result is 5. 
Result so far: 1436.5
The remainder is 25 after subtracting 405 from 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 8:
If we divide 250 by 81, we get 3 and a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 1436.53
Deduct 243 from 250 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 9:
81 goes into 70 0 times with a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 1436.53
If we take 0 away from 70, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 10:
The number 81 fits into 700 8 times, leaving a remainder of 52.
Write down 8 as next digit of the result. 
Result so far: 1436.5308
Subtract 648 from 700 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 11:
81 goes into 520 6 times with a remainder of 34.
Record the quotient 6 as the next digit in the result. 
Result so far: 1436.53086
Subtract 486 from 520 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 12:
81 can be fit into 340 4 times, resulting in a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 1436.530864
Subtracting 324 from 340 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 13:
81 can be fit into 160 1 times, resulting in a remainder of 79.
Use 1 as the next digit of our solution. 
Result so far: 1436.5308641
Subtract 81 from 160 to 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.

Let's proceed to step 14:
81 goes into 790 9 times with a remainder of 61.
Record the quotient 9 as the next digit in the result. 
Result so far: 1436.53086419
If we take 729 away from 790, we end up 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.

The final outcome is 1436.53086419, with a leftover of 6.1e-08.
