812415 ÷ 83 
Our goal is to divide 812415 by 83.

On to step 1:
If we divide 8 by 83, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 83

Advancing to step 2:
If we divide 81 by 83, we get 0 and a remainder of 81.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 81 after subtracting 0 from 81.
Append the next digit (2) from the dividend to 81 and continue with: 812 / 83

Moving on to step 3:
When dividing 812 by 83, we get 9 with a remainder of 65.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we take 747 away from 812, we end up with 65.
Fetch the next digit (4) from the dividend, attach it to 65 and continue: 654 / 83

Going ahead to step 4:
If we divide 654 by 83, we get 7 and a remainder of 73.
The next digit of our result is 7. 
Result so far: 97.0
Subtract 581 from 654 to get 73.
Append the next digit (1) from the dividend to 73 and continue with: 731 / 83

Advancing to step 5:
83 goes into 731 8 times with a remainder of 67.
Use 8 as the next digit of our solution. 
Result so far: 978.0
If we subtract 664 from 731, we get 67.
Take the next digit (5) from the dividend and append it to 67, then repeat: 675 / 83

On to step 6:
83 can be fit into 675 8 times, resulting in a remainder of 11.
Use 8 as the next digit of our solution. 
Result so far: 9788.0
Deduct 664 from 675 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 7:
83 can be fit into 110 1 times, resulting in a remainder of 27.
The number 1 becomes the next digit in our result. 
Result so far: 9788.1
Deduct 83 from 110 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 8:
270 divided by 83 is 3 with a remainder of 21.
The number 3 becomes the next digit in our result. 
Result so far: 9788.13
Subtract 249 from 270 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 9:
If we divide 210 by 83, we get 2 and a remainder of 44.
The next digit of our result is 2. 
Result so far: 9788.132
Subtract 166 from 210 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 10:
The number 83 fits into 440 5 times, leaving a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 9788.1325
The remainder is 25 after subtracting 415 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 11:
250 divided by 83 is 3 with a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 9788.13253
Subtract 249 from 250 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 12:
When dividing 10 by 83, we get 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 9788.13253
Subtracting 0 from 10 leaves us 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.

Going ahead to step 13:
83 can be fit into 100 1 times, resulting in a remainder of 17.
Record the quotient 1 as the next digit in the result. 
Result so far: 9788.1325301
If we take 83 away from 100, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 14:
83 can be fit into 170 2 times, resulting in a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 9788.13253012
Subtract 166 from 170 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final result is 9788.13253012 with a remainder of 4e-09.
