We're dividing 20981962 by 666 
We want to figure out the number of times 20981962 can be divided by 666.

On to step 1:
The number 666 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 666

Advancing to step 2:
666 goes into 20 0 times with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 20 and we're left with 20.
Bring next digit (9) of the dividend behind the 20 and repeat the process: 209 / 666

Step 3:
If we divide 209 by 666, we get 0 and a remainder of 209.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 209, we get 209.
Take the next digit (8) from the dividend and append it to 209, then repeat: 2098 / 666

Moving on to step 4:
If we divide 2098 by 666, we get 3 and a remainder of 100.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Deduct 1998 from 2098 and we're left with 100.
Take the next digit (1) from the dividend and append it to 100, then repeat: 1001 / 666

On to step 5:
1001 divided by 666 is 1 with a remainder of 335.
The number 1 becomes the next digit in our result. 
Result so far: 31.0
The remainder is 335 after subtracting 666 from 1001.
Take the next digit (9) from the dividend and append it to 335, then repeat: 3359 / 666

Going ahead to step 6:
The number 666 fits into 3359 5 times, leaving a remainder of 29.
The next digit of our result is 5. 
Result so far: 315.0
If we take 3330 away from 3359, we end up with 29.
Grab the next digit (6) from the dividend, add it to 29, then carry on: 296 / 666

Step 7:
666 goes into 296 0 times with a remainder of 296.
The next digit of our result is 0. 
Result so far: 3150.0
Deduct 0 from 296 and we're left with 296.
Fetch the next digit (2) from the dividend, attach it to 296 and continue: 2962 / 666

Advancing to step 8:
The number 666 fits into 2962 4 times, leaving a remainder of 298.
Write down 4 as next digit of the result. 
Result so far: 31504.0
Deduct 2664 from 2962 and we're left with 298.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

Advancing to step 9:
666 can be fit into 2980 4 times, resulting in a remainder of 316.
Use 4 as the next digit of our solution. 
Result so far: 31504.4
If we take 2664 away from 2980, we end up with 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

Let's proceed to step 10:
3160 divided by 666 is 4 with a remainder of 496.
Record the quotient 4 as the next digit in the result. 
Result so far: 31504.44
If we take 2664 away from 3160, we end up with 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

After the division, we end up with 31504.44 and a remainder of 0.496.
