81779419 divided by 81 
Let's see how many times 81 fits into 81779419.

Moving on to step 1:
If we divide 8 by 81, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 81

On to step 2:
81 can be fit into 81 1 times, resulting in a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 81 from 81 and we're left with 0.
Take the next digit (7) from the dividend and append it to 0, then repeat: 7 / 81

Going ahead to step 3:
81 can be fit into 7 0 times, resulting in a remainder of 7.
The next digit of our result is 0. 
Result so far: 10.0
Subtract 0 from 7 to get 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 81

On to step 4:
The number 81 fits into 77 0 times, leaving a remainder of 77.
Record the quotient 0 as the next digit in the result. 
Result so far: 100.0
Subtracting 0 from 77 leaves us with 77.
Fetch the next digit (9) from the dividend, attach it to 77 and continue: 779 / 81

On to step 5:
81 can be fit into 779 9 times, resulting in a remainder of 50.
Write down 9 as next digit of the result. 
Result so far: 1009.0
Deduct 729 from 779 and we're left with 50.
Bring next digit (4) of the dividend behind the 50 and repeat the process: 504 / 81

Step 6:
81 goes into 504 6 times with a remainder of 18.
Use 6 as the next digit of our solution. 
Result so far: 10096.0
The remainder is 18 after subtracting 486 from 504.
Include the next digit (1) from the dividend after 18, then repeat: 181 / 81

Going ahead to step 7:
When dividing 181 by 81, we get 2 with a remainder of 19.
Record the quotient 2 as the next digit in the result. 
Result so far: 100962.0
Subtracting 162 from 181 leaves us with 19.
Grab the next digit (9) from the dividend, add it to 19, then carry on: 199 / 81

Moving on to step 8:
If we divide 199 by 81, we get 2 and a remainder of 37.
Write down 2 as next digit of the result. 
Result so far: 1009622.0
The remainder is 37 after subtracting 162 from 199.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Moving on to step 9:
81 goes into 370 4 times with a remainder of 46.
Record the quotient 4 as the next digit in the result. 
Result so far: 1009622.4
The remainder is 46 after subtracting 324 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 10:
81 goes into 460 5 times with a remainder of 55.
Put 5 as the next digit of the answer. 
Result so far: 1009622.45
The remainder is 55 after subtracting 405 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 11:
When dividing 550 by 81, we get 6 with a remainder of 64.
Use 6 as the next digit of our solution. 
Result so far: 1009622.456
Deduct 486 from 550 and we're left 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.

On to step 12:
When dividing 640 by 81, we get 7 with a remainder of 73.
Put 7 as the next digit of the answer. 
Result so far: 1009622.4567
Subtracting 567 from 640 leaves us with 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 13:
The number 81 fits into 730 9 times, leaving a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 1009622.45679
If we take 729 away from 730, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 14:
81 can be fit into 10 0 times, resulting in a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 1009622.45679
If we take 0 away from 10, we end up 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.

On to step 15:
81 goes into 100 1 times with a remainder of 19.
The next digit of our result is 1. 
Result so far: 1009622.4567901
Deduct 81 from 100 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 16:
81 can be fit into 190 2 times, resulting in a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 1009622.45679012
If we take 162 away from 190, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

The final result is 1009622.45679012 with a remainder of 2.8e-08.
