Let's divide 258216 by 81
Let's see how many times 81 fits into 258216.

Moving on to step 1:
81 goes into 2 0 times with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 81

Step 2:
25 divided by 81 is 0 with a remainder of 25.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 25 to get 25.
Append the next digit (8) from the dividend to 25 and continue with: 258 / 81

On to step 3:
81 goes into 258 3 times with a remainder of 15.
The next digit of our result is 3. 
Result so far: 3.0
Subtracting 243 from 258 leaves us with 15.
Take the next digit (2) from the dividend and append it to 15, then repeat: 152 / 81

On to step 4:
81 goes into 152 1 times with a remainder of 71.
Put 1 as the next digit of the answer. 
Result so far: 31.0
Subtract 81 from 152 to get 71.
Include the next digit (1) from the dividend after 71, then repeat: 711 / 81

On to step 5:
When dividing 711 by 81, we get 8 with a remainder of 63.
The number 8 becomes the next digit in our result. 
Result so far: 318.0
Subtracting 648 from 711 leaves us with 63.
Grab the next digit (6) from the dividend, add it to 63, then carry on: 636 / 81

Moving on to step 6:
81 can be fit into 636 7 times, resulting in a remainder of 69.
Put 7 as the next digit of the answer. 
Result so far: 3187.0
Subtract 567 from 636 to get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Advancing to step 7:
81 can be fit into 690 8 times, resulting in a remainder of 42.
The number 8 becomes the next digit in our result. 
Result so far: 3187.8
If we subtract 648 from 690, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 8:
81 can be fit into 420 5 times, resulting in a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 3187.85
Deduct 405 from 420 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 9:
150 divided by 81 is 1 with a remainder of 69.
Write down 1 as next digit of the result. 
Result so far: 3187.851
If we take 81 away from 150, we end up with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Step 10:
690 divided by 81 is 8 with a remainder of 42.
The next digit of our result is 8. 
Result so far: 3187.8518
Subtract 648 from 690 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 11:
81 can be fit into 420 5 times, resulting in a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 3187.85185
Deduct 405 from 420 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 12:
The number 81 fits into 150 1 times, leaving a remainder of 69.
The next digit of our result is 1. 
Result so far: 3187.851851
The remainder is 69 after subtracting 81 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Step 13:
690 divided by 81 is 8 with a remainder of 42.
The next digit of our result is 8. 
Result so far: 3187.8518518
Subtracting 648 from 690 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 14:
420 divided by 81 is 5 with a remainder of 15.
The next digit of our result is 5. 
Result so far: 3187.85185185
Subtract 405 from 420 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The quotient of the division is 3187.85185185, and the remainder is 1.5e-08.
