We look at the division of 640676 by 93 
Let's see how many times 93 fits into 640676.

Let's proceed to step 1:
If we divide 6 by 93, we get 0 and a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 93

Let's proceed to step 2:
The number 93 fits into 64 0 times, leaving a remainder of 64.
The number 0 becomes the next digit in our 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 / 93

Going ahead to step 3:
The number 93 fits into 640 6 times, leaving a remainder of 82.
The next digit of our result is 6. 
Result so far: 6.0
Subtract 558 from 640 to get 82.
Append the next digit (6) from the dividend to 82 and continue with: 826 / 93

Advancing to step 4:
The number 93 fits into 826 8 times, leaving a remainder of 82.
The next digit of our result is 8. 
Result so far: 68.0
Deduct 744 from 826 and we're left with 82.
Bring next digit (7) of the dividend behind the 82 and repeat the process: 827 / 93

Moving on to step 5:
93 can be fit into 827 8 times, resulting in a remainder of 83.
Put 8 as the next digit of the answer. 
Result so far: 688.0
If we subtract 744 from 827, we get 83.
Append the next digit (6) from the dividend to 83 and continue with: 836 / 93

Let's proceed to step 6:
93 goes into 836 8 times with a remainder of 92.
The next digit of our result is 8. 
Result so far: 6888.0
The remainder is 92 after subtracting 744 from 836.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Step 7:
When dividing 920 by 93, we get 9 with a remainder of 83.
Write down 9 as next digit of the result. 
Result so far: 6888.9
Subtract 837 from 920 to get 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Advancing to step 8:
The number 93 fits into 830 8 times, leaving a remainder of 86.
Use 8 as the next digit of our solution. 
Result so far: 6888.98
Subtracting 744 from 830 leaves us with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Moving on to step 9:
860 divided by 93 is 9 with a remainder of 23.
Record the quotient 9 as the next digit in the result. 
Result so far: 6888.989
Subtract 837 from 860 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 10:
93 goes into 230 2 times with a remainder of 44.
The number 2 becomes the next digit in our result. 
Result so far: 6888.9892
Subtracting 186 from 230 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 11:
The number 93 fits into 440 4 times, leaving a remainder of 68.
The number 4 becomes the next digit in our result. 
Result so far: 6888.98924
Subtracting 372 from 440 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 12:
If we divide 680 by 93, we get 7 and a remainder of 29.
Record the quotient 7 as the next digit in the result. 
Result so far: 6888.989247
Subtract 651 from 680 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Step 13:
When dividing 290 by 93, we get 3 with a remainder of 11.
The next digit of our result is 3. 
Result so far: 6888.9892473
The remainder is 11 after subtracting 279 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 14:
93 goes into 110 1 times with a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 6888.98924731
If we take 93 away from 110, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

The final outcome is 6888.98924731, with a leftover of 1.7e-08.
