77450217 divided by 81 
We want to divide 77450217 by 81.

Step 1:
81 goes into 7 0 times with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 81

On to step 2:
If we divide 77 by 81, we get 0 and a remainder of 77.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 77 leaves us with 77.
Bring next digit (4) of the dividend behind the 77 and repeat the process: 774 / 81

Advancing to step 3:
81 can be fit into 774 9 times, resulting in a remainder of 45.
Write down 9 as next digit of the result. 
Result so far: 9.0
Deduct 729 from 774 and we're left with 45.
Include the next digit (5) from the dividend after 45, then repeat: 455 / 81

Advancing to step 4:
81 goes into 455 5 times with a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 95.0
If we take 405 away from 455, we end up with 50.
Grab the next digit (0) from the dividend, add it to 50, then carry on: 500 / 81

Step 5:
500 divided by 81 is 6 with a remainder of 14.
The next digit of our result is 6. 
Result so far: 956.0
The remainder is 14 after subtracting 486 from 500.
Take the next digit (2) from the dividend and append it to 14, then repeat: 142 / 81

Moving on to step 6:
142 divided by 81 is 1 with a remainder of 61.
Put 1 as the next digit of the answer. 
Result so far: 9561.0
Deduct 81 from 142 and we're left with 61.
Append the next digit (1) from the dividend to 61 and continue with: 611 / 81

Moving on to step 7:
81 can be fit into 611 7 times, resulting in a remainder of 44.
The next digit of our result is 7. 
Result so far: 95617.0
The remainder is 44 after subtracting 567 from 611.
Fetch the next digit (7) from the dividend, attach it to 44 and continue: 447 / 81

Let's proceed to step 8:
81 can be fit into 447 5 times, resulting in a remainder of 42.
Put 5 as the next digit of the answer. 
Result so far: 956175.0
Subtract 405 from 447 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.

Let's proceed to step 9:
If we divide 420 by 81, we get 5 and a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 956175.5
Subtracting 405 from 420 leaves us 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.

Moving on to step 10:
When dividing 150 by 81, we get 1 with a remainder of 69.
The number 1 becomes the next digit in our result. 
Result so far: 956175.51
Subtract 81 from 150 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.

On to step 11:
When dividing 690 by 81, we get 8 with a remainder of 42.
Record the quotient 8 as the next digit in the result. 
Result so far: 956175.518
Deduct 648 from 690 and we're left 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.

Step 12:
When dividing 420 by 81, we get 5 with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 956175.5185
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.

Step 13:
The number 81 fits into 150 1 times, leaving a remainder of 69.
Put 1 as the next digit of the answer. 
Result so far: 956175.51851
Subtracting 81 from 150 leaves us 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.

Going ahead to step 14:
690 divided by 81 is 8 with a remainder of 42.
The next digit of our result is 8. 
Result so far: 956175.518518
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.

Going ahead to step 15:
When dividing 420 by 81, we get 5 with a remainder of 15.
The next digit of our result is 5. 
Result so far: 956175.5185185
Subtracting 405 from 420 leaves us 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.

Moving on to step 16:
150 divided by 81 is 1 with a remainder of 69.
Record the quotient 1 as the next digit in the result. 
Result so far: 956175.51851851
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.

After the division, we end up with 956175.51851851 and a remainder of 6.9e-08.
