We're dividing 15981705 by 821 
Our goal is to divide 15981705 by 821.

Advancing to step 1:
1 divided by 821 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 821

Advancing to step 2:
When dividing 15 by 821, we get 0 with a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Grab the next digit (9) from the dividend, add it to 15, then carry on: 159 / 821

Advancing to step 3:
821 goes into 159 0 times with a remainder of 159.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 159 and we're left with 159.
Fetch the next digit (8) from the dividend, attach it to 159 and continue: 1598 / 821

Going ahead to step 4:
1598 divided by 821 is 1 with a remainder of 777.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 821 from 1598 and we're left with 777.
Append the next digit (1) from the dividend to 777 and continue with: 7771 / 821

On to step 5:
821 can be fit into 7771 9 times, resulting in a remainder of 382.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
Subtracting 7389 from 7771 leaves us with 382.
Take the next digit (7) from the dividend and append it to 382, then repeat: 3827 / 821

On to step 6:
When dividing 3827 by 821, we get 4 with a remainder of 543.
The number 4 becomes the next digit in our result. 
Result so far: 194.0
Deduct 3284 from 3827 and we're left with 543.
Include the next digit (0) from the dividend after 543, then repeat: 5430 / 821

Moving on to step 7:
5430 divided by 821 is 6 with a remainder of 504.
Put 6 as the next digit of the answer. 
Result so far: 1946.0
Subtract 4926 from 5430 to get 504.
Include the next digit (5) from the dividend after 504, then repeat: 5045 / 821

Moving on to step 8:
821 goes into 5045 6 times with a remainder of 119.
The next digit of our result is 6. 
Result so far: 19466.0
If we subtract 4926 from 5045, we get 119.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

Advancing to step 9:
1190 divided by 821 is 1 with a remainder of 369.
The number 1 becomes the next digit in our result. 
Result so far: 19466.1
If we take 821 away from 1190, we end up with 369.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3690, and continue the process.

Let's proceed to step 10:
821 goes into 3690 4 times with a remainder of 406.
The next digit of our result is 4. 
Result so far: 19466.14
The remainder is 406 after subtracting 3284 from 3690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

Moving on to step 11:
4060 divided by 821 is 4 with a remainder of 776.
Record the quotient 4 as the next digit in the result. 
Result so far: 19466.144
If we take 3284 away from 4060, we end up with 776.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7760, and continue the process.

After the division, we end up with 19466.144 and a remainder of 0.0776.
