We divide 644872 by 6
Let's see how many times 6 fits into 644872.

Let's proceed to step 1:
6 can be fit into 6 1 times, resulting in a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 6 from 6 and we're left with 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 6

Step 2:
The number 6 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 10.0
The remainder is 4 after subtracting 0 from 4.
Append the next digit (4) from the dividend to 4 and continue with: 44 / 6

Going ahead to step 3:
When dividing 44 by 6, we get 7 with a remainder of 2.
Record the quotient 7 as the next digit in the result. 
Result so far: 107.0
Subtracting 42 from 44 leaves us with 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 6

Advancing to step 4:
28 divided by 6 is 4 with a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 1074.0
Subtract 24 from 28 to get 4.
Grab the next digit (7) from the dividend, add it to 4, then carry on: 47 / 6

Going ahead to step 5:
When dividing 47 by 6, we get 7 with a remainder of 5.
The next digit of our result is 7. 
Result so far: 10747.0
Subtracting 42 from 47 leaves us with 5.
Bring next digit (2) of the dividend behind the 5 and repeat the process: 52 / 6

Let's proceed to step 6:
6 goes into 52 8 times with a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 107478.0
The remainder is 4 after subtracting 48 from 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 7:
When dividing 40 by 6, we get 6 with a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 107478.6
If we subtract 36 from 40, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 8:
If we divide 40 by 6, we get 6 and a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 107478.66
Deduct 36 from 40 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Our division results in 107478.66 with a remaining 0.004.
