We're dividing 780478 by 81 
Our goal is to divide 780478 by 81.

Advancing to step 1:
The number 81 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 81

Advancing to step 2:
When dividing 78 by 81, we get 0 with a remainder of 78.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 78 leaves us with 78.
Grab the next digit (0) from the dividend, add it to 78, then carry on: 780 / 81

Going ahead to step 3:
When dividing 780 by 81, we get 9 with a remainder of 51.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we take 729 away from 780, we end up with 51.
Include the next digit (4) from the dividend after 51, then repeat: 514 / 81

On to step 4:
If we divide 514 by 81, we get 6 and a remainder of 28.
Use 6 as the next digit of our solution. 
Result so far: 96.0
Deduct 486 from 514 and we're left with 28.
Take the next digit (7) from the dividend and append it to 28, then repeat: 287 / 81

On to step 5:
81 goes into 287 3 times with a remainder of 44.
Record the quotient 3 as the next digit in the result. 
Result so far: 963.0
The remainder is 44 after subtracting 243 from 287.
Grab the next digit (8) from the dividend, add it to 44, then carry on: 448 / 81

Moving on to step 6:
If we divide 448 by 81, we get 5 and a remainder of 43.
Write down 5 as next digit of the result. 
Result so far: 9635.0
If we subtract 405 from 448, we get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

On to step 7:
The number 81 fits into 430 5 times, leaving a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 9635.5
The remainder is 25 after subtracting 405 from 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 8:
250 divided by 81 is 3 with a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 9635.53
If we take 243 away from 250, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 9:
The number 81 fits into 70 0 times, leaving a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 9635.53
If we subtract 0 from 70, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 10:
81 goes into 700 8 times with a remainder of 52.
Record the quotient 8 as the next digit in the result. 
Result so far: 9635.5308
Subtract 648 from 700 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 11:
81 can be fit into 520 6 times, resulting in a remainder of 34.
Write down 6 as next digit of the result. 
Result so far: 9635.53086
Subtract 486 from 520 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 12:
The number 81 fits into 340 4 times, leaving a remainder of 16.
The next digit of our result is 4. 
Result so far: 9635.530864
Deduct 324 from 340 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 13:
81 can be fit into 160 1 times, resulting in a remainder of 79.
Use 1 as the next digit of our solution. 
Result so far: 9635.5308641
Subtract 81 from 160 to get 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

On to step 14:
790 divided by 81 is 9 with a remainder of 61.
Put 9 as the next digit of the answer. 
Result so far: 9635.53086419
Subtract 729 from 790 to get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

After the division, we end up with 9635.53086419 and a remainder of 6.1e-08.
