Let's divide 892235 by 81
The aim is to understand the frequency of 81 in 892235.

Let's proceed to step 1:
81 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (9) from the dividend, add it to 8, then carry on: 89 / 81

On to step 2:
89 divided by 81 is 1 with a remainder of 8.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 81 from 89 leaves us with 8.
Include the next digit (2) from the dividend after 8, then repeat: 82 / 81

Advancing to step 3:
81 goes into 82 1 times with a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
The remainder is 1 after subtracting 81 from 82.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 81

Advancing to step 4:
12 divided by 81 is 0 with a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 110.0
Subtract 0 from 12 to get 12.
Bring next digit (3) of the dividend behind the 12 and repeat the process: 123 / 81

On to step 5:
When dividing 123 by 81, we get 1 with a remainder of 42.
Write down 1 as next digit of the result. 
Result so far: 1101.0
If we take 81 away from 123, we end up with 42.
Include the next digit (5) from the dividend after 42, then repeat: 425 / 81

Advancing to step 6:
81 can be fit into 425 5 times, resulting in a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 11015.0
If we take 405 away from 425, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 7:
If we divide 200 by 81, we get 2 and a remainder of 38.
Write down 2 as next digit of the result. 
Result so far: 11015.2
Subtracting 162 from 200 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 8:
If we divide 380 by 81, we get 4 and a remainder of 56.
Record the quotient 4 as the next digit in the result. 
Result so far: 11015.24
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.

Advancing to step 9:
81 goes into 560 6 times with a remainder of 74.
Record the quotient 6 as the next digit in the result. 
Result so far: 11015.246
Subtracting 486 from 560 leaves us 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.

Advancing to step 10:
If we divide 740 by 81, we get 9 and a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 11015.2469
Deduct 729 from 740 and we're left with 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:
110 divided by 81 is 1 with a remainder of 29.
Use 1 as the next digit of our solution. 
Result so far: 11015.24691
If we subtract 81 from 110, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 12:
If we divide 290 by 81, we get 3 and a remainder of 47.
Use 3 as the next digit of our solution. 
Result so far: 11015.246913
Subtracting 243 from 290 leaves us with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Advancing to step 13:
81 can be fit into 470 5 times, resulting in a remainder of 65.
Write down 5 as next digit of the result. 
Result so far: 11015.2469135
Subtracting 405 from 470 leaves us 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:
When dividing 650 by 81, we get 8 with a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 11015.24691358
Deduct 648 from 650 and we're left with 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 quotient of the division is 11015.24691358, and the remainder is 2e-09.
