Let's divide 415715 by 81
We're looking to find how many times 81 goes into 415715.

Going ahead to step 1:
4 divided by 81 is 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Append the next digit (1) from the dividend to 4 and continue with: 41 / 81

Step 2:
When dividing 41 by 81, we get 0 with a remainder of 41.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 41, we end up with 41.
Append the next digit (5) from the dividend to 41 and continue with: 415 / 81

Going ahead to step 3:
When dividing 415 by 81, we get 5 with a remainder of 10.
The next digit of our result is 5. 
Result so far: 5.0
The remainder is 10 after subtracting 405 from 415.
Grab the next digit (7) from the dividend, add it to 10, then carry on: 107 / 81

Advancing to step 4:
The number 81 fits into 107 1 times, leaving a remainder of 26.
Use 1 as the next digit of our solution. 
Result so far: 51.0
The remainder is 26 after subtracting 81 from 107.
Bring next digit (1) of the dividend behind the 26 and repeat the process: 261 / 81

Advancing to step 5:
261 divided by 81 is 3 with a remainder of 18.
Write down 3 as next digit of the result. 
Result so far: 513.0
If we take 243 away from 261, we end up with 18.
Fetch the next digit (5) from the dividend, attach it to 18 and continue: 185 / 81

Let's proceed to step 6:
The number 81 fits into 185 2 times, leaving a remainder of 23.
Record the quotient 2 as the next digit in the result. 
Result so far: 5132.0
If we take 162 away from 185, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 7:
The number 81 fits into 230 2 times, leaving a remainder of 68.
The next digit of our result is 2. 
Result so far: 5132.2
If we take 162 away from 230, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 8:
81 goes into 680 8 times with a remainder of 32.
The next digit of our result is 8. 
Result so far: 5132.28
Subtracting 648 from 680 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 9:
81 can be fit into 320 3 times, resulting in a remainder of 77.
Use 3 as the next digit of our solution. 
Result so far: 5132.283
Subtract 243 from 320 to get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

On to step 10:
If we divide 770 by 81, we get 9 and a remainder of 41.
The next digit of our result is 9. 
Result so far: 5132.2839
Subtract 729 from 770 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Going ahead to step 11:
If we divide 410 by 81, we get 5 and a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 5132.28395
Subtracting 405 from 410 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 12:
When dividing 50 by 81, we get 0 with a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 5132.28395
Deduct 0 from 50 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 13:
If we divide 500 by 81, we get 6 and a remainder of 14.
Use 6 as the next digit of our solution. 
Result so far: 5132.2839506
If we take 486 away from 500, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 14:
The number 81 fits into 140 1 times, leaving a remainder of 59.
Record the quotient 1 as the next digit in the result. 
Result so far: 5132.28395061
Deduct 81 from 140 and we're left with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Our division results in 5132.28395061 with a remaining 5.9e-08.
