Let's divide 640343 by 60
We want to figure out the number of times 640343 can be divided by 60.

Going ahead to step 1:
When dividing 6 by 60, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 60

Advancing to step 2:
60 can be fit into 64 1 times, resulting in a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 60 from 64, we get 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 60

On to step 3:
40 divided by 60 is 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Deduct 0 from 40 and we're left with 40.
Grab the next digit (3) from the dividend, add it to 40, then carry on: 403 / 60

Step 4:
When dividing 403 by 60, we get 6 with a remainder of 43.
Write down 6 as next digit of the result. 
Result so far: 106.0
The remainder is 43 after subtracting 360 from 403.
Grab the next digit (4) from the dividend, add it to 43, then carry on: 434 / 60

Step 5:
The number 60 fits into 434 7 times, leaving a remainder of 14.
Write down 7 as next digit of the result. 
Result so far: 1067.0
If we subtract 420 from 434, we get 14.
Grab the next digit (3) from the dividend, add it to 14, then carry on: 143 / 60

Let's proceed to step 6:
60 goes into 143 2 times with a remainder of 23.
Use 2 as the next digit of our solution. 
Result so far: 10672.0
If we take 120 away from 143, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 7:
If we divide 230 by 60, we get 3 and a remainder of 50.
Use 3 as the next digit of our solution. 
Result so far: 10672.3
Deduct 180 from 230 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 8:
The number 60 fits into 500 8 times, leaving a remainder of 20.
Use 8 as the next digit of our solution. 
Result so far: 10672.38
Subtract 480 from 500 to 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.

Let's proceed to step 9:
60 can be fit into 200 3 times, resulting in a remainder of 20.
Put 3 as the next digit of the answer. 
Result so far: 10672.383
If we take 180 away from 200, we end up 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.

On to step 10:
The number 60 fits into 200 3 times, leaving a remainder of 20.
The next digit of our result is 3. 
Result so far: 10672.3833
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 final result is 10672.3833 with a remainder of 0.0002.
