Let's divide 685415 by 81
We're looking to find how many times 81 goes into 685415.

On to step 1:
81 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 81

Going ahead to step 2:
When dividing 68 by 81, we get 0 with a remainder of 68.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 68 leaves us with 68.
Fetch the next digit (5) from the dividend, attach it to 68 and continue: 685 / 81

Let's proceed to step 3:
685 divided by 81 is 8 with a remainder of 37.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we take 648 away from 685, we end up with 37.
Bring next digit (4) of the dividend behind the 37 and repeat the process: 374 / 81

Going ahead to step 4:
81 can be fit into 374 4 times, resulting in a remainder of 50.
The number 4 becomes the next digit in our result. 
Result so far: 84.0
If we subtract 324 from 374, we get 50.
Include the next digit (1) from the dividend after 50, then repeat: 501 / 81

On to step 5:
When dividing 501 by 81, we get 6 with a remainder of 15.
Record the quotient 6 as the next digit in the result. 
Result so far: 846.0
The remainder is 15 after subtracting 486 from 501.
Append the next digit (5) from the dividend to 15 and continue with: 155 / 81

Step 6:
81 goes into 155 1 times with a remainder of 74.
The next digit of our result is 1. 
Result so far: 8461.0
The remainder is 74 after subtracting 81 from 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

On to step 7:
If we divide 740 by 81, we get 9 and a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 8461.9
Subtract 729 from 740 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 8:
81 goes into 110 1 times with a remainder of 29.
The next digit of our result is 1. 
Result so far: 8461.91
Subtracting 81 from 110 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 9:
The number 81 fits into 290 3 times, leaving a remainder of 47.
Use 3 as the next digit of our solution. 
Result so far: 8461.913
The remainder is 47 after subtracting 243 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Going ahead to step 10:
When dividing 470 by 81, we get 5 with a remainder of 65.
Write down 5 as next digit of the result. 
Result so far: 8461.9135
Deduct 405 from 470 and we're left with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Going ahead to step 11:
650 divided by 81 is 8 with a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 8461.91358
If we take 648 away from 650, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 12:
20 divided by 81 is 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 8461.91358
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 13:
81 goes into 200 2 times with a remainder of 38.
Put 2 as the next digit of the answer. 
Result so far: 8461.9135802
Deduct 162 from 200 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 14:
When dividing 380 by 81, we get 4 with a remainder of 56.
Use 4 as the next digit of our solution. 
Result so far: 8461.91358024
If we subtract 324 from 380, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

The quotient of the division is 8461.91358024, and the remainder is 5.6e-08.
