Let's divide 238851 by 81
The aim is to understand the frequency of 81 in 238851.

Let's proceed to step 1:
2 divided by 81 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 81

Advancing to step 2:
23 divided by 81 is 0 with a remainder of 23.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 23 after subtracting 0 from 23.
Take the next digit (8) from the dividend and append it to 23, then repeat: 238 / 81

On to step 3:
81 goes into 238 2 times with a remainder of 76.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 162 away from 238, we end up with 76.
Grab the next digit (8) from the dividend, add it to 76, then carry on: 768 / 81

Going ahead to step 4:
If we divide 768 by 81, we get 9 and a remainder of 39.
Write down 9 as next digit of the result. 
Result so far: 29.0
Subtract 729 from 768 to get 39.
Bring next digit (5) of the dividend behind the 39 and repeat the process: 395 / 81

Moving on to step 5:
When dividing 395 by 81, we get 4 with a remainder of 71.
Use 4 as the next digit of our solution. 
Result so far: 294.0
Deduct 324 from 395 and we're left with 71.
Bring next digit (1) of the dividend behind the 71 and repeat the process: 711 / 81

Let's proceed to step 6:
711 divided by 81 is 8 with a remainder of 63.
Write down 8 as next digit of the result. 
Result so far: 2948.0
If we subtract 648 from 711, we get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Let's proceed to step 7:
The number 81 fits into 630 7 times, leaving a remainder of 63.
The next digit of our result is 7. 
Result so far: 2948.7
Subtract 567 from 630 to get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

On to step 8:
630 divided by 81 is 7 with a remainder of 63.
The next digit of our result is 7. 
Result so far: 2948.77
If we take 567 away from 630, we end up with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

The quotient of the division is 2948.77, and the remainder is 0.063.
