We're dividing 821463 by 1 
We want to divide 821463 by 1.

Step 1:
1 goes into 8 8 times with a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 8.0
The remainder is 0 after subtracting 8 from 8.
Take the next digit (2) from the dividend and append it to 0, then repeat: 2 / 1

Advancing to step 2:
2 divided by 1 is 2 with a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 82.0
Subtract 2 from 2 to get 0.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 1

Going ahead to step 3:
1 goes into 1 1 times with a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 821.0
The remainder is 0 after subtracting 1 from 1.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 1

Going ahead to step 4:
1 can be fit into 4 4 times, resulting in a remainder of 0.
The next digit of our result is 4. 
Result so far: 8214.0
Subtracting 4 from 4 leaves us with 0.
Bring next digit (6) of the dividend behind the 0 and repeat the process: 6 / 1

Going ahead to step 5:
1 can be fit into 6 6 times, resulting in a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 82146.0
If we take 6 away from 6, we end up with 0.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 1

Step 6:
The number 1 fits into 3 3 times, leaving a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 821463.0
If we take 3 away from 3, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 7:
1 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 821463.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 8:
0 divided by 1 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 821463.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 821463.0, with a leftover of 0.0.
