The number 812 fits into 65 0 times, leaving a remainder of 65.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 65, we get 65.
Bring next digit (7) of the dividend behind the 65 and repeat the process: 657 / 812

On to step 3:
When dividing 657 by 812, we get 0 with a remainder of 657.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 657 after subtracting 0 from 657.
Append the next digit (3) from the dividend to 657 and continue with: 6573 / 812

On to step 4:
The number 812 fits into 6573 8 times, leaving a remainder of 77.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we take 6496 away from 6573, we end up with 77.
Fetch the next digit (7) from the dividend, attach it to 77 and continue: 777 / 812

Moving on to step 5:
812 can be fit into 777 0 times, resulting in a remainder of 777.
Write down 0 as next digit of the result. 
Result so far: 80.0
Subtract 0 from 777 to get 777.
Bring next digit (4) of the dividend behind the 777 and repeat the process: 7774 / 812

Step 6:
The number 812 fits into 7774 9 times, leaving a remainder of 466.
Write down 9 as next digit of the result. 
Result so far: 809.0
Deduct 7308 from 7774 and we're left with 466.
Fetch the next digit (1) from the dividend, attach it to 466 and continue: 4661 / 812

On to step 7:
If we divide 4661 by 812, we get 5 and a remainder of 601.
Use 5 as the next digit of our solution. 
Result so far: 8095.0
Subtract 4060 from 4661 to get 601.
Fetch the next digit (9) from the dividend, attach it to 601 and continue: 6019 / 812

Advancing to step 8:
6019 divided by 812 is 7 with a remainder of 335.
Put 7 as the next digit of the answer. 
Result so far: 80957.0
If we subtract 5684 from 6019, we get 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

Advancing to step 9:
812 can be fit into 3350 4 times, resulting in a remainder of 102.
Write down 4 as next digit of the result. 
Result so far: 80957.4
Deduct 3248 from 3350 and we're left with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

On to step 10:
812 can be fit into 1020 1 times, resulting in a remainder of 208.
Put 1 as the next digit of the answer. 
Result so far: 80957.41
Subtracting 812 from 1020 leaves us with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Moving on to step 11:
812 can be fit into 2080 2 times, resulting in a remainder of 456.
Record the quotient 2 as the next digit in the result. 
Result so far: 80957.412
The remainder is 456 after subtracting 1624 from 2080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

Advancing to step 12:
4560 divided by 812 is 5 with a remainder of 500.
Use 5 as the next digit of our solution. 
Result so far: 80957.4125
If we subtract 4060 from 4560, we get 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Step 13:
5000 divided by 812 is 6 with a remainder of 128.
The next digit of our result is 6. 
Result so far: 80957.41256
Subtracting 4872 from 5000 leaves us with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Let's proceed to step 14:
The number 812 fits into 1280 1 times, leaving a remainder of 468.
Use 1 as the next digit of our solution. 
Result so far: 80957.412561
Subtract 812 from 1280 to get 468.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4680, and continue the process.

On to step 15:
The number 812 fits into 4680 5 times, leaving a remainder of 620.
Put 5 as the next digit of the answer. 
Result so far: 80957.4125615
If we subtract 4060 from 4680, we get 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

On to step 16:
When dividing 6200 by 812, we get 7 with a remainder of 516.
Record the quotient 7 as the next digit in the result. 
Result so far: 80957.41256157
Subtract 5684 from 6200 to get 516.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5160, and continue the process.

The final outcome is 80957.41256157, with a leftover of 5.16e-07.
