We look at the division of 66543428 by 671 
Our goal is to divide 66543428 by 671.

Going ahead to step 1:
6 divided by 671 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 671

Moving on to step 2:
The number 671 fits into 66 0 times, leaving a remainder of 66.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 66 after subtracting 0 from 66.
Take the next digit (5) from the dividend and append it to 66, then repeat: 665 / 671

Going ahead to step 3:
If we divide 665 by 671, we get 0 and a remainder of 665.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 665 and we're left with 665.
Take the next digit (4) from the dividend and append it to 665, then repeat: 6654 / 671

On to step 4:
671 goes into 6654 9 times with a remainder of 615.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
The remainder is 615 after subtracting 6039 from 6654.
Grab the next digit (3) from the dividend, add it to 615, then carry on: 6153 / 671

Going ahead to step 5:
671 goes into 6153 9 times with a remainder of 114.
Use 9 as the next digit of our solution. 
Result so far: 99.0
If we take 6039 away from 6153, we end up with 114.
Append the next digit (4) from the dividend to 114 and continue with: 1144 / 671

Going ahead to step 6:
671 can be fit into 1144 1 times, resulting in a remainder of 473.
Write down 1 as next digit of the result. 
Result so far: 991.0
If we subtract 671 from 1144, we get 473.
Grab the next digit (2) from the dividend, add it to 473, then carry on: 4732 / 671

Moving on to step 7:
If we divide 4732 by 671, we get 7 and a remainder of 35.
The next digit of our result is 7. 
Result so far: 9917.0
Deduct 4697 from 4732 and we're left with 35.
Grab the next digit (8) from the dividend, add it to 35, then carry on: 358 / 671

Advancing to step 8:
If we divide 358 by 671, we get 0 and a remainder of 358.
Write down 0 as next digit of the result. 
Result so far: 99170.0
Subtract 0 from 358 to get 358.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

Let's proceed to step 9:
When dividing 3580 by 671, we get 5 with a remainder of 225.
Put 5 as the next digit of the answer. 
Result so far: 99170.5
If we take 3355 away from 3580, we end up with 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Going ahead to step 10:
671 can be fit into 2250 3 times, resulting in a remainder of 237.
Put 3 as the next digit of the answer. 
Result so far: 99170.53
If we take 2013 away from 2250, we end up with 237.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2370, and continue the process.

Advancing to step 11:
If we divide 2370 by 671, we get 3 and a remainder of 357.
The number 3 becomes the next digit in our result. 
Result so far: 99170.533
Deduct 2013 from 2370 and we're left with 357.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3570, and continue the process.

The final outcome is 99170.533, with a leftover of 0.0357.
