We divide 65667005 by 644
Let's see how many times 644 fits into 65667005.

Step 1:
When dividing 6 by 644, we get 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (5) of the dividend behind the 6 and repeat the process: 65 / 644

Moving on to step 2:
644 goes into 65 0 times with a remainder of 65.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 65 and we're left with 65.
Include the next digit (6) from the dividend after 65, then repeat: 656 / 644

Moving on to step 3:
The number 644 fits into 656 1 times, leaving a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 644 from 656 leaves us with 12.
Append the next digit (6) from the dividend to 12 and continue with: 126 / 644

Moving on to step 4:
644 goes into 126 0 times with a remainder of 126.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we take 0 away from 126, we end up with 126.
Grab the next digit (7) from the dividend, add it to 126, then carry on: 1267 / 644

Advancing to step 5:
644 can be fit into 1267 1 times, resulting in a remainder of 623.
Put 1 as the next digit of the answer. 
Result so far: 101.0
Deduct 644 from 1267 and we're left with 623.
Grab the next digit (0) from the dividend, add it to 623, then carry on: 6230 / 644

Step 6:
The number 644 fits into 6230 9 times, leaving a remainder of 434.
Put 9 as the next digit of the answer. 
Result so far: 1019.0
If we take 5796 away from 6230, we end up with 434.
Include the next digit (0) from the dividend after 434, then repeat: 4340 / 644

Step 7:
If we divide 4340 by 644, we get 6 and a remainder of 476.
Put 6 as the next digit of the answer. 
Result so far: 10196.0
Subtracting 3864 from 4340 leaves us with 476.
Include the next digit (5) from the dividend after 476, then repeat: 4765 / 644

Let's proceed to step 8:
When dividing 4765 by 644, we get 7 with a remainder of 257.
The next digit of our result is 7. 
Result so far: 101967.0
If we subtract 4508 from 4765, we get 257.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2570, and continue the process.

Advancing to step 9:
644 goes into 2570 3 times with a remainder of 638.
Put 3 as the next digit of the answer. 
Result so far: 101967.3
Subtracting 1932 from 2570 leaves us with 638.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6380, and continue the process.

Going ahead to step 10:
When dividing 6380 by 644, we get 9 with a remainder of 584.
The next digit of our result is 9. 
Result so far: 101967.39
Subtracting 5796 from 6380 leaves us with 584.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5840, and continue the process.

On to step 11:
If we divide 5840 by 644, we get 9 and a remainder of 44.
Record the quotient 9 as the next digit in the result. 
Result so far: 101967.399
Subtract 5796 from 5840 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

The quotient of the division is 101967.399, and the remainder is 0.0044.
