Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 821

Step 2:
821 can be fit into 86 0 times, resulting in a remainder of 86.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 86 to get 86.
Take the next digit (2) from the dividend and append it to 86, then repeat: 862 / 821

On to step 3:
821 can be fit into 862 1 times, resulting in a remainder of 41.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 821 from 862 and we're left with 41.
Fetch the next digit (8) from the dividend, attach it to 41 and continue: 418 / 821

Advancing to step 4:
The number 821 fits into 418 0 times, leaving a remainder of 418.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Deduct 0 from 418 and we're left with 418.
Fetch the next digit (2) from the dividend, attach it to 418 and continue: 4182 / 821

Moving on to step 5:
If we divide 4182 by 821, we get 5 and a remainder of 77.
Use 5 as the next digit of our solution. 
Result so far: 105.0
The remainder is 77 after subtracting 4105 from 4182.
Fetch the next digit (6) from the dividend, attach it to 77 and continue: 776 / 821

Let's proceed to step 6:
776 divided by 821 is 0 with a remainder of 776.
Record the quotient 0 as the next digit in the result. 
Result so far: 1050.0
The remainder is 776 after subtracting 0 from 776.
Include the next digit (1) from the dividend after 776, then repeat: 7761 / 821

On to step 7:
When dividing 7761 by 821, we get 9 with a remainder of 372.
Use 9 as the next digit of our solution. 
Result so far: 10509.0
If we subtract 7389 from 7761, we get 372.
Append the next digit (5) from the dividend to 372 and continue with: 3725 / 821

Let's proceed to step 8:
821 can be fit into 3725 4 times, resulting in a remainder of 441.
The next digit of our result is 4. 
Result so far: 105094.0
If we subtract 3284 from 3725, we get 441.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4410, and continue the process.

Advancing to step 9:
The number 821 fits into 4410 5 times, leaving a remainder of 305.
The next digit of our result is 5. 
Result so far: 105094.5
Deduct 4105 from 4410 and we're left with 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

Advancing to step 10:
If we divide 3050 by 821, we get 3 and a remainder of 587.
Use 3 as the next digit of our solution. 
Result so far: 105094.53
Subtracting 2463 from 3050 leaves us with 587.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5870, and continue the process.

Step 11:
821 goes into 5870 7 times with a remainder of 123.
Put 7 as the next digit of the answer. 
Result so far: 105094.537
Subtracting 5747 from 5870 leaves us with 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

Advancing to step 12:
When dividing 1230 by 821, we get 1 with a remainder of 409.
The next digit of our result is 1. 
Result so far: 105094.5371
If we take 821 away from 1230, we end up with 409.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4090, and continue the process.

Step 13:
When dividing 4090 by 821, we get 4 with a remainder of 806.
Use 4 as the next digit of our solution. 
Result so far: 105094.53714
If we take 3284 away from 4090, we end up with 806.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8060, and continue the process.

On to step 14:
821 can be fit into 8060 9 times, resulting in a remainder of 671.
Write down 9 as next digit of the result. 
Result so far: 105094.537149
Deduct 7389 from 8060 and we're left with 671.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6710, and continue the process.

Let's proceed to step 15:
If we divide 6710 by 821, we get 8 and a remainder of 142.
The number 8 becomes the next digit in our result. 
Result so far: 105094.5371498
If we subtract 6568 from 6710, we get 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Moving on to step 16:
If we divide 1420 by 821, we get 1 and a remainder of 599.
Use 1 as the next digit of our solution. 
Result so far: 105094.53714981
The remainder is 599 after subtracting 821 from 1420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5990, and continue the process.

The final outcome is 105094.53714981, with a leftover of 5.99e-07.
