644664 divided by 93 
We want to figure out the number of times 644664 can be divided by 93.

Moving on to step 1:
The number 93 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 93

Step 2:
When dividing 64 by 93, we get 0 with a remainder of 64.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 64 to get 64.
Take the next digit (4) from the dividend and append it to 64, then repeat: 644 / 93

Step 3:
When dividing 644 by 93, we get 6 with a remainder of 86.
Write down 6 as next digit of the result. 
Result so far: 6.0
Subtracting 558 from 644 leaves us with 86.
Bring next digit (6) of the dividend behind the 86 and repeat the process: 866 / 93

Let's proceed to step 4:
866 divided by 93 is 9 with a remainder of 29.
Write down 9 as next digit of the result. 
Result so far: 69.0
Deduct 837 from 866 and we're left with 29.
Fetch the next digit (6) from the dividend, attach it to 29 and continue: 296 / 93

Let's proceed to step 5:
93 goes into 296 3 times with a remainder of 17.
Record the quotient 3 as the next digit in the result. 
Result so far: 693.0
Deduct 279 from 296 and we're left with 17.
Include the next digit (4) from the dividend after 17, then repeat: 174 / 93

Step 6:
93 goes into 174 1 times with a remainder of 81.
The next digit of our result is 1. 
Result so far: 6931.0
If we subtract 93 from 174, we get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Let's proceed to step 7:
93 goes into 810 8 times with a remainder of 66.
Write down 8 as next digit of the result. 
Result so far: 6931.8
If we take 744 away from 810, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Let's proceed to step 8:
If we divide 660 by 93, we get 7 and a remainder of 9.
Put 7 as the next digit of the answer. 
Result so far: 6931.87
Deduct 651 from 660 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 9:
93 can be fit into 90 0 times, resulting in a remainder of 90.
Put 0 as the next digit of the answer. 
Result so far: 6931.87
Deduct 0 from 90 and we're left with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Step 10:
If we divide 900 by 93, we get 9 and a remainder of 63.
The next digit of our result is 9. 
Result so far: 6931.8709
If we take 837 away from 900, we end up with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Step 11:
When dividing 630 by 93, we get 6 with a remainder of 72.
Put 6 as the next digit of the answer. 
Result so far: 6931.87096
If we take 558 away from 630, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 12:
The number 93 fits into 720 7 times, leaving a remainder of 69.
Write down 7 as next digit of the result. 
Result so far: 6931.870967
Deduct 651 from 720 and we're left with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

On to step 13:
When dividing 690 by 93, we get 7 with a remainder of 39.
The number 7 becomes the next digit in our result. 
Result so far: 6931.8709677
If we subtract 651 from 690, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

After the division, we end up with 6931.8709677 and a remainder of 3.9e-07.
