We divide 674384 by 81
The aim is to understand the frequency of 81 in 674384.

Going ahead to step 1:
81 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (7) of the dividend behind the 6 and repeat the process: 67 / 81

Moving on to step 2:
81 can be fit into 67 0 times, resulting in a remainder of 67.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 67, we get 67.
Bring next digit (4) of the dividend behind the 67 and repeat the process: 674 / 81

Moving on to step 3:
If we divide 674 by 81, we get 8 and a remainder of 26.
The next digit of our result is 8. 
Result so far: 8.0
Subtract 648 from 674 to get 26.
Take the next digit (3) from the dividend and append it to 26, then repeat: 263 / 81

Advancing to step 4:
263 divided by 81 is 3 with a remainder of 20.
Use 3 as the next digit of our solution. 
Result so far: 83.0
Subtracting 243 from 263 leaves us with 20.
Grab the next digit (8) from the dividend, add it to 20, then carry on: 208 / 81

Going ahead to step 5:
81 can be fit into 208 2 times, resulting in a remainder of 46.
The number 2 becomes the next digit in our result. 
Result so far: 832.0
The remainder is 46 after subtracting 162 from 208.
Take the next digit (4) from the dividend and append it to 46, then repeat: 464 / 81

Going ahead to step 6:
81 can be fit into 464 5 times, resulting in a remainder of 59.
Put 5 as the next digit of the answer. 
Result so far: 8325.0
If we subtract 405 from 464, we get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

On to step 7:
590 divided by 81 is 7 with a remainder of 23.
Use 7 as the next digit of our solution. 
Result so far: 8325.7
Subtracting 567 from 590 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 8:
230 divided by 81 is 2 with a remainder of 68.
Write down 2 as next digit of the result. 
Result so far: 8325.72
Subtract 162 from 230 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 9:
When dividing 680 by 81, we get 8 with a remainder of 32.
The number 8 becomes the next digit in our result. 
Result so far: 8325.728
The remainder is 32 after subtracting 648 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 10:
The number 81 fits into 320 3 times, leaving a remainder of 77.
The next digit of our result is 3. 
Result so far: 8325.7283
If we take 243 away from 320, we end up with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

On to step 11:
If we divide 770 by 81, we get 9 and a remainder of 41.
The next digit of our result is 9. 
Result so far: 8325.72839
Subtract 729 from 770 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Going ahead to step 12:
81 goes into 410 5 times with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 8325.728395
The remainder is 5 after subtracting 405 from 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 13:
81 can be fit into 50 0 times, resulting in a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 8325.728395
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 14:
When dividing 500 by 81, we get 6 with a remainder of 14.
The next digit of our result is 6. 
Result so far: 8325.72839506
Subtracting 486 from 500 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

After the division, we end up with 8325.72839506 and a remainder of 1.4e-08.
