Let's divide 19984825 by 81
We're looking to find how many times 81 goes into 19984825.

Moving on to step 1:
When dividing 1 by 81, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 81

Moving on to step 2:
When dividing 19 by 81, we get 0 with a remainder of 19.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 19 leaves us with 19.
Bring next digit (9) of the dividend behind the 19 and repeat the process: 199 / 81

Let's proceed to step 3:
199 divided by 81 is 2 with a remainder of 37.
The next digit of our result is 2. 
Result so far: 2.0
If we take 162 away from 199, we end up with 37.
Append the next digit (8) from the dividend to 37 and continue with: 378 / 81

Advancing to step 4:
If we divide 378 by 81, we get 4 and a remainder of 54.
Put 4 as the next digit of the answer. 
Result so far: 24.0
Subtracting 324 from 378 leaves us with 54.
Include the next digit (4) from the dividend after 54, then repeat: 544 / 81

Advancing to step 5:
If we divide 544 by 81, we get 6 and a remainder of 58.
Use 6 as the next digit of our solution. 
Result so far: 246.0
Subtract 486 from 544 to get 58.
Grab the next digit (8) from the dividend, add it to 58, then carry on: 588 / 81

Going ahead to step 6:
81 can be fit into 588 7 times, resulting in a remainder of 21.
Write down 7 as next digit of the result. 
Result so far: 2467.0
The remainder is 21 after subtracting 567 from 588.
Take the next digit (2) from the dividend and append it to 21, then repeat: 212 / 81

Advancing to step 7:
81 can be fit into 212 2 times, resulting in a remainder of 50.
The number 2 becomes the next digit in our result. 
Result so far: 24672.0
Subtracting 162 from 212 leaves us with 50.
Fetch the next digit (5) from the dividend, attach it to 50 and continue: 505 / 81

On to step 8:
When dividing 505 by 81, we get 6 with a remainder of 19.
Record the quotient 6 as the next digit in the result. 
Result so far: 246726.0
Subtract 486 from 505 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 9:
If we divide 190 by 81, we get 2 and a remainder of 28.
Write down 2 as next digit of the result. 
Result so far: 246726.2
The remainder is 28 after subtracting 162 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 10:
The number 81 fits into 280 3 times, leaving a remainder of 37.
The number 3 becomes the next digit in our result. 
Result so far: 246726.23
Deduct 243 from 280 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Step 11:
If we divide 370 by 81, we get 4 and a remainder of 46.
Write down 4 as next digit of the result. 
Result so far: 246726.234
Subtracting 324 from 370 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 12:
When dividing 460 by 81, we get 5 with a remainder of 55.
Use 5 as the next digit of our solution. 
Result so far: 246726.2345
If we take 405 away from 460, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Moving on to step 13:
81 goes into 550 6 times with a remainder of 64.
The number 6 becomes the next digit in our result. 
Result so far: 246726.23456
If we take 486 away from 550, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 14:
If we divide 640 by 81, we get 7 and a remainder of 73.
Write down 7 as next digit of the result. 
Result so far: 246726.234567
Subtract 567 from 640 to get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Let's proceed to step 15:
81 goes into 730 9 times with a remainder of 1.
The next digit of our result is 9. 
Result so far: 246726.2345679
Subtract 729 from 730 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 16:
If we divide 10 by 81, we get 0 and a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 246726.2345679
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final result is 246726.2345679 with a remainder of 1e-08.
