We divide 759962 by 81
The aim is to understand the frequency of 81 in 759962.

Let's proceed to step 1:
81 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Append the next digit (5) from the dividend to 7 and continue with: 75 / 81

Step 2:
81 can be fit into 75 0 times, resulting in a remainder of 75.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 75 leaves us with 75.
Take the next digit (9) from the dividend and append it to 75, then repeat: 759 / 81

On to step 3:
759 divided by 81 is 9 with a remainder of 30.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtract 729 from 759 to get 30.
Fetch the next digit (9) from the dividend, attach it to 30 and continue: 309 / 81

Moving on to step 4:
309 divided by 81 is 3 with a remainder of 66.
Write down 3 as next digit of the result. 
Result so far: 93.0
Deduct 243 from 309 and we're left with 66.
Append the next digit (6) from the dividend to 66 and continue with: 666 / 81

Going ahead to step 5:
When dividing 666 by 81, we get 8 with a remainder of 18.
Write down 8 as next digit of the result. 
Result so far: 938.0
If we subtract 648 from 666, we get 18.
Bring next digit (2) of the dividend behind the 18 and repeat the process: 182 / 81

Moving on to step 6:
81 can be fit into 182 2 times, resulting in a remainder of 20.
Use 2 as the next digit of our solution. 
Result so far: 9382.0
The remainder is 20 after subtracting 162 from 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 7:
If we divide 200 by 81, we get 2 and a remainder of 38.
Record the quotient 2 as the next digit in the result. 
Result so far: 9382.2
If we subtract 162 from 200, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 8:
The number 81 fits into 380 4 times, leaving a remainder of 56.
Write down 4 as next digit of the result. 
Result so far: 9382.24
If we subtract 324 from 380, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 9:
81 can be fit into 560 6 times, resulting in a remainder of 74.
The next digit of our result is 6. 
Result so far: 9382.246
If we take 486 away from 560, we end up with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

On to step 10:
740 divided by 81 is 9 with a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 9382.2469
If we subtract 729 from 740, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 11:
81 can be fit into 110 1 times, resulting in a remainder of 29.
The next digit of our result is 1. 
Result so far: 9382.24691
Deduct 81 from 110 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Moving on to step 12:
When dividing 290 by 81, we get 3 with a remainder of 47.
The number 3 becomes the next digit in our result. 
Result so far: 9382.246913
If we subtract 243 from 290, we get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Step 13:
If we divide 470 by 81, we get 5 and a remainder of 65.
The next digit of our result is 5. 
Result so far: 9382.2469135
Deduct 405 from 470 and we're left with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Going ahead to step 14:
The number 81 fits into 650 8 times, leaving a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 9382.24691358
Subtract 648 from 650 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The final result is 9382.24691358 with a remainder of 2e-09.
