We divide 21629646 by 660
We're looking to find how many times 660 goes into 21629646.

Advancing to step 1:
When dividing 2 by 660, we get 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 660

On to step 2:
When dividing 21 by 660, we get 0 with a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Take the next digit (6) from the dividend and append it to 21, then repeat: 216 / 660

Moving on to step 3:
If we divide 216 by 660, we get 0 and a remainder of 216.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 216 and we're left with 216.
Bring next digit (2) of the dividend behind the 216 and repeat the process: 2162 / 660

On to step 4:
If we divide 2162 by 660, we get 3 and a remainder of 182.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 1980 from 2162 and we're left with 182.
Include the next digit (9) from the dividend after 182, then repeat: 1829 / 660

Step 5:
660 goes into 1829 2 times with a remainder of 509.
Put 2 as the next digit of the answer. 
Result so far: 32.0
If we subtract 1320 from 1829, we get 509.
Include the next digit (6) from the dividend after 509, then repeat: 5096 / 660

Going ahead to step 6:
The number 660 fits into 5096 7 times, leaving a remainder of 476.
Put 7 as the next digit of the answer. 
Result so far: 327.0
If we subtract 4620 from 5096, we get 476.
Bring next digit (4) of the dividend behind the 476 and repeat the process: 4764 / 660

Step 7:
The number 660 fits into 4764 7 times, leaving a remainder of 144.
Write down 7 as next digit of the result. 
Result so far: 3277.0
The remainder is 144 after subtracting 4620 from 4764.
Append the next digit (6) from the dividend to 144 and continue with: 1446 / 660

Step 8:
660 goes into 1446 2 times with a remainder of 126.
The next digit of our result is 2. 
Result so far: 32772.0
If we subtract 1320 from 1446, we get 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Moving on to step 9:
1260 divided by 660 is 1 with a remainder of 600.
The next digit of our result is 1. 
Result so far: 32772.1
The remainder is 600 after subtracting 660 from 1260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Moving on to step 10:
When dividing 6000 by 660, we get 9 with a remainder of 60.
Put 9 as the next digit of the answer. 
Result so far: 32772.19
The remainder is 60 after subtracting 5940 from 6000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 11:
The number 660 fits into 600 0 times, leaving a remainder of 600.
The number 0 becomes the next digit in our result. 
Result so far: 32772.19
Subtracting 0 from 600 leaves us with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Step 12:
If we divide 6000 by 660, we get 9 and a remainder of 60.
Put 9 as the next digit of the answer. 
Result so far: 32772.1909
Subtracting 5940 from 6000 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 13:
600 divided by 660 is 0 with a remainder of 600.
The next digit of our result is 0. 
Result so far: 32772.1909
Subtracting 0 from 600 leaves us with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Moving on to step 14:
The number 660 fits into 6000 9 times, leaving a remainder of 60.
The number 9 becomes the next digit in our result. 
Result so far: 32772.190909
Subtract 5940 from 6000 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 15:
When dividing 600 by 660, we get 0 with a remainder of 600.
The number 0 becomes the next digit in our result. 
Result so far: 32772.190909
If we take 0 away from 600, we end up with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Going ahead to step 16:
660 goes into 6000 9 times with a remainder of 60.
Put 9 as the next digit of the answer. 
Result so far: 32772.19090909
If we take 5940 away from 6000, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

The final outcome is 32772.19090909, with a leftover of 6e-08.
