We're dividing 19819921 by 671 
We want to divide 19819921 by 671.

Step 1:
1 divided by 671 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 671

Step 2:
If we divide 19 by 671, we get 0 and a remainder of 19.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 19 to get 19.
Fetch the next digit (8) from the dividend, attach it to 19 and continue: 198 / 671

Moving on to step 3:
If we divide 198 by 671, we get 0 and a remainder of 198.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 198 leaves us with 198.
Grab the next digit (1) from the dividend, add it to 198, then carry on: 1981 / 671

Advancing to step 4:
When dividing 1981 by 671, we get 2 with a remainder of 639.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 1342 from 1981 and we're left with 639.
Take the next digit (9) from the dividend and append it to 639, then repeat: 6399 / 671

Step 5:
When dividing 6399 by 671, we get 9 with a remainder of 360.
Put 9 as the next digit of the answer. 
Result so far: 29.0
The remainder is 360 after subtracting 6039 from 6399.
Include the next digit (9) from the dividend after 360, then repeat: 3609 / 671

Moving on to step 6:
When dividing 3609 by 671, we get 5 with a remainder of 254.
Use 5 as the next digit of our solution. 
Result so far: 295.0
If we subtract 3355 from 3609, we get 254.
Fetch the next digit (2) from the dividend, attach it to 254 and continue: 2542 / 671

Advancing to step 7:
671 can be fit into 2542 3 times, resulting in a remainder of 529.
The number 3 becomes the next digit in our result. 
Result so far: 2953.0
Deduct 2013 from 2542 and we're left with 529.
Take the next digit (1) from the dividend and append it to 529, then repeat: 5291 / 671

On to step 8:
When dividing 5291 by 671, we get 7 with a remainder of 594.
Use 7 as the next digit of our solution. 
Result so far: 29537.0
Subtract 4697 from 5291 to get 594.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5940, and continue the process.

Let's proceed to step 9:
When dividing 5940 by 671, we get 8 with a remainder of 572.
Write down 8 as next digit of the result. 
Result so far: 29537.8
Subtracting 5368 from 5940 leaves us with 572.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5720, and continue the process.

On to step 10:
The number 671 fits into 5720 8 times, leaving a remainder of 352.
The next digit of our result is 8. 
Result so far: 29537.88
The remainder is 352 after subtracting 5368 from 5720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Our division results in 29537.88 with a remaining 0.352.
