We're dividing 644432 by 60 
We want to divide 644432 by 60.

On to step 1:
60 can be fit into 6 0 times, resulting in a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 60

Advancing to step 2:
The number 60 fits into 64 1 times, leaving a remainder of 4.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 60 from 64 and we're left with 4.
Bring next digit (4) of the dividend behind the 4 and repeat the process: 44 / 60

Step 3:
When dividing 44 by 60, we get 0 with a remainder of 44.
The next digit of our result is 0. 
Result so far: 10.0
Deduct 0 from 44 and we're left with 44.
Take the next digit (4) from the dividend and append it to 44, then repeat: 444 / 60

Advancing to step 4:
60 goes into 444 7 times with a remainder of 24.
Put 7 as the next digit of the answer. 
Result so far: 107.0
If we subtract 420 from 444, we get 24.
Fetch the next digit (3) from the dividend, attach it to 24 and continue: 243 / 60

On to step 5:
243 divided by 60 is 4 with a remainder of 3.
Record the quotient 4 as the next digit in the result. 
Result so far: 1074.0
If we subtract 240 from 243, we get 3.
Append the next digit (2) from the dividend to 3 and continue with: 32 / 60

Moving on to step 6:
60 goes into 32 0 times with a remainder of 32.
Put 0 as the next digit of the answer. 
Result so far: 10740.0
If we subtract 0 from 32, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 7:
The number 60 fits into 320 5 times, leaving a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 10740.5
Deduct 300 from 320 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.

Going ahead to step 8:
When dividing 200 by 60, we get 3 with a remainder of 20.
Use 3 as the next digit of our solution. 
Result so far: 10740.53
The remainder is 20 after subtracting 180 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 9:
If we divide 200 by 60, we get 3 and a remainder of 20.
Record the quotient 3 as the next digit in the result. 
Result so far: 10740.533
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.

After the division, we end up with 10740.533 and a remainder of 0.002.
