Let's divide 640353 by 60
Our goal is to divide 640353 by 60.

Moving on to step 1:
When dividing 6 by 60, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 60

Moving on to step 2:
When dividing 64 by 60, we get 1 with a remainder of 4.
The next digit of our result is 1. 
Result so far: 1.0
If we take 60 away from 64, we end up with 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 60

Step 3:
If we divide 40 by 60, we get 0 and a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Subtract 0 from 40 to get 40.
Grab the next digit (3) from the dividend, add it to 40, then carry on: 403 / 60

Step 4:
403 divided by 60 is 6 with a remainder of 43.
Put 6 as the next digit of the answer. 
Result so far: 106.0
Subtract 360 from 403 to get 43.
Fetch the next digit (5) from the dividend, attach it to 43 and continue: 435 / 60

Advancing to step 5:
60 can be fit into 435 7 times, resulting in a remainder of 15.
The next digit of our result is 7. 
Result so far: 1067.0
Deduct 420 from 435 and we're left with 15.
Bring next digit (3) of the dividend behind the 15 and repeat the process: 153 / 60

Advancing to step 6:
When dividing 153 by 60, we get 2 with a remainder of 33.
The number 2 becomes the next digit in our result. 
Result so far: 10672.0
The remainder is 33 after subtracting 120 from 153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Let's proceed to step 7:
The number 60 fits into 330 5 times, leaving a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 10672.5
Subtracting 300 from 330 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 8:
60 goes into 300 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 10672.55
Subtracting 300 from 300 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 10672.55 with a remainder of 0.0.
