We're dividing 16957387 by 821 
We want to divide 16957387 by 821.

Moving on to step 1:
821 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 821

Going ahead to step 2:
821 goes into 16 0 times with a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 16 and we're left with 16.
Append the next digit (9) from the dividend to 16 and continue with: 169 / 821

Going ahead to step 3:
If we divide 169 by 821, we get 0 and a remainder of 169.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 169 leaves us with 169.
Fetch the next digit (5) from the dividend, attach it to 169 and continue: 1695 / 821

Moving on to step 4:
1695 divided by 821 is 2 with a remainder of 53.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 1642 away from 1695, we end up with 53.
Grab the next digit (7) from the dividend, add it to 53, then carry on: 537 / 821

Going ahead to step 5:
If we divide 537 by 821, we get 0 and a remainder of 537.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
If we take 0 away from 537, we end up with 537.
Bring next digit (3) of the dividend behind the 537 and repeat the process: 5373 / 821

Step 6:
821 goes into 5373 6 times with a remainder of 447.
Record the quotient 6 as the next digit in the result. 
Result so far: 206.0
Deduct 4926 from 5373 and we're left with 447.
Fetch the next digit (8) from the dividend, attach it to 447 and continue: 4478 / 821

Step 7:
821 goes into 4478 5 times with a remainder of 373.
Record the quotient 5 as the next digit in the result. 
Result so far: 2065.0
Subtracting 4105 from 4478 leaves us with 373.
Fetch the next digit (7) from the dividend, attach it to 373 and continue: 3737 / 821

On to step 8:
821 can be fit into 3737 4 times, resulting in a remainder of 453.
Record the quotient 4 as the next digit in the result. 
Result so far: 20654.0
Subtracting 3284 from 3737 leaves us with 453.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4530, and continue the process.

Moving on to step 9:
If we divide 4530 by 821, we get 5 and a remainder of 425.
The next digit of our result is 5. 
Result so far: 20654.5
If we take 4105 away from 4530, we end up with 425.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

Let's proceed to step 10:
The number 821 fits into 4250 5 times, leaving a remainder of 145.
Put 5 as the next digit of the answer. 
Result so far: 20654.55
If we take 4105 away from 4250, we end up with 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Our division results in 20654.55 with a remaining 0.145.
