We divide 640792 by 3
We want to figure out the number of times 640792 can be divided by 3.

Let's proceed to step 1:
When dividing 6 by 3, we get 2 with a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 6 from 6 leaves us with 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 3

Advancing to step 2:
When dividing 4 by 3, we get 1 with a remainder of 1.
The next digit of our result is 1. 
Result so far: 21.0
The remainder is 1 after subtracting 3 from 4.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 3

Going ahead to step 3:
If we divide 10 by 3, we get 3 and a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 213.0
Subtracting 9 from 10 leaves us with 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 3

On to step 4:
If we divide 17 by 3, we get 5 and a remainder of 2.
The number 5 becomes the next digit in our result. 
Result so far: 2135.0
The remainder is 2 after subtracting 15 from 17.
Bring next digit (9) of the dividend behind the 2 and repeat the process: 29 / 3

Let's proceed to step 5:
3 can be fit into 29 9 times, resulting in a remainder of 2.
Put 9 as the next digit of the answer. 
Result so far: 21359.0
The remainder is 2 after subtracting 27 from 29.
Grab the next digit (2) from the dividend, add it to 2, then carry on: 22 / 3

Going ahead to step 6:
3 goes into 22 7 times with a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 213597.0
Subtract 21 from 22 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 7:
3 goes into 10 3 times with a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 213597.3
Subtract 9 from 10 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 8:
When dividing 10 by 3, we get 3 with a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 213597.33
If we take 9 away from 10, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Our division results in 213597.33 with a remaining 0.001.
