We divide 640715 by 68
We're looking to find how many times 68 goes into 640715.

On to step 1:
68 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 68

Let's proceed to step 2:
The number 68 fits into 64 0 times, leaving a remainder of 64.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 64 after subtracting 0 from 64.
Take the next digit (0) from the dividend and append it to 64, then repeat: 640 / 68

Going ahead to step 3:
If we divide 640 by 68, we get 9 and a remainder of 28.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we take 612 away from 640, we end up with 28.
Bring next digit (7) of the dividend behind the 28 and repeat the process: 287 / 68

Moving on to step 4:
If we divide 287 by 68, we get 4 and a remainder of 15.
The number 4 becomes the next digit in our result. 
Result so far: 94.0
Subtracting 272 from 287 leaves us with 15.
Fetch the next digit (1) from the dividend, attach it to 15 and continue: 151 / 68

Going ahead to step 5:
151 divided by 68 is 2 with a remainder of 15.
The number 2 becomes the next digit in our result. 
Result so far: 942.0
Subtracting 136 from 151 leaves us with 15.
Bring next digit (5) of the dividend behind the 15 and repeat the process: 155 / 68

Advancing to step 6:
68 goes into 155 2 times with a remainder of 19.
The number 2 becomes the next digit in our result. 
Result so far: 9422.0
If we subtract 136 from 155, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 7:
When dividing 190 by 68, we get 2 with a remainder of 54.
Write down 2 as next digit of the result. 
Result so far: 9422.2
If we take 136 away from 190, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 8:
The number 68 fits into 540 7 times, leaving a remainder of 64.
The next digit of our result is 7. 
Result so far: 9422.27
Deduct 476 from 540 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 9:
The number 68 fits into 640 9 times, leaving a remainder of 28.
Record the quotient 9 as the next digit in the result. 
Result so far: 9422.279
Subtract 612 from 640 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 10:
280 divided by 68 is 4 with a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 9422.2794
Subtract 272 from 280 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 11:
If we divide 80 by 68, we get 1 and a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 9422.27941
Deduct 68 from 80 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 12:
When dividing 120 by 68, we get 1 with a remainder of 52.
The next digit of our result is 1. 
Result so far: 9422.279411
Subtracting 68 from 120 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

After the division, we end up with 9422.279411 and a remainder of 5.2e-06.
