644540 divided by 60 
We want to divide 644540 by 60.

Moving on to step 1:
When dividing 6 by 60, we get 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.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 60

Going ahead to step 2:
When dividing 64 by 60, we get 1 with a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 60 from 64 leaves us with 4.
Append the next digit (4) from the dividend to 4 and continue with: 44 / 60

Let's proceed to step 3:
The number 60 fits into 44 0 times, leaving a remainder of 44.
Write down 0 as next digit of the result. 
Result so far: 10.0
Deduct 0 from 44 and we're left with 44.
Grab the next digit (5) from the dividend, add it to 44, then carry on: 445 / 60

Moving on to step 4:
60 can be fit into 445 7 times, resulting in a remainder of 25.
Put 7 as the next digit of the answer. 
Result so far: 107.0
The remainder is 25 after subtracting 420 from 445.
Include the next digit (4) from the dividend after 25, then repeat: 254 / 60

Let's proceed to step 5:
The number 60 fits into 254 4 times, leaving a remainder of 14.
Use 4 as the next digit of our solution. 
Result so far: 1074.0
Deduct 240 from 254 and we're left with 14.
Bring next digit (0) of the dividend behind the 14 and repeat the process: 140 / 60

On to step 6:
If we divide 140 by 60, we get 2 and a remainder of 20.
Put 2 as the next digit of the answer. 
Result so far: 10742.0
The remainder is 20 after subtracting 120 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 7:
60 can be fit into 200 3 times, resulting in a remainder of 20.
Write down 3 as next digit of the result. 
Result so far: 10742.3
If we subtract 180 from 200, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 8:
60 goes into 200 3 times with a remainder of 20.
The next digit of our result is 3. 
Result so far: 10742.33
Deduct 180 from 200 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The quotient of the division is 10742.33, and the remainder is 0.02.
