We look at the division of 66299662 by 644 
We want to figure out the number of times 66299662 can be divided by 644.

Step 1:
6 divided by 644 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 644

Going ahead to step 2:
66 divided by 644 is 0 with a remainder of 66.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 66 and we're left with 66.
Take the next digit (2) from the dividend and append it to 66, then repeat: 662 / 644

Step 3:
644 goes into 662 1 times with a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 644 from 662 and we're left with 18.
Include the next digit (9) from the dividend after 18, then repeat: 189 / 644

Moving on to step 4:
189 divided by 644 is 0 with a remainder of 189.
The next digit of our result is 0. 
Result so far: 10.0
Subtract 0 from 189 to get 189.
Include the next digit (9) from the dividend after 189, then repeat: 1899 / 644

Let's proceed to step 5:
When dividing 1899 by 644, we get 2 with a remainder of 611.
Record the quotient 2 as the next digit in the result. 
Result so far: 102.0
Deduct 1288 from 1899 and we're left with 611.
Include the next digit (6) from the dividend after 611, then repeat: 6116 / 644

On to step 6:
If we divide 6116 by 644, we get 9 and a remainder of 320.
Write down 9 as next digit of the result. 
Result so far: 1029.0
Subtract 5796 from 6116 to get 320.
Grab the next digit (6) from the dividend, add it to 320, then carry on: 3206 / 644

Step 7:
The number 644 fits into 3206 4 times, leaving a remainder of 630.
Use 4 as the next digit of our solution. 
Result so far: 10294.0
If we subtract 2576 from 3206, we get 630.
Include the next digit (2) from the dividend after 630, then repeat: 6302 / 644

On to step 8:
644 can be fit into 6302 9 times, resulting in a remainder of 506.
Use 9 as the next digit of our solution. 
Result so far: 102949.0
The remainder is 506 after subtracting 5796 from 6302.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5060, and continue the process.

On to step 9:
If we divide 5060 by 644, we get 7 and a remainder of 552.
Use 7 as the next digit of our solution. 
Result so far: 102949.7
Subtract 4508 from 5060 to get 552.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5520, and continue the process.

Let's proceed to step 10:
The number 644 fits into 5520 8 times, leaving a remainder of 368.
The number 8 becomes the next digit in our result. 
Result so far: 102949.78
If we subtract 5152 from 5520, we get 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Moving on to step 11:
When dividing 3680 by 644, we get 5 with a remainder of 460.
Write down 5 as next digit of the result. 
Result so far: 102949.785
Subtract 3220 from 3680 to get 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Step 12:
644 can be fit into 4600 7 times, resulting in a remainder of 92.
Use 7 as the next digit of our solution. 
Result so far: 102949.7857
Deduct 4508 from 4600 and we're left with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Let's proceed to step 13:
If we divide 920 by 644, we get 1 and a remainder of 276.
Record the quotient 1 as the next digit in the result. 
Result so far: 102949.78571
Deduct 644 from 920 and we're left with 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Advancing to step 14:
644 can be fit into 2760 4 times, resulting in a remainder of 184.
The number 4 becomes the next digit in our result. 
Result so far: 102949.785714
Subtracting 2576 from 2760 leaves us with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Let's proceed to step 15:
The number 644 fits into 1840 2 times, leaving a remainder of 552.
Record the quotient 2 as the next digit in the result. 
Result so far: 102949.7857142
Subtract 1288 from 1840 to get 552.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5520, and continue the process.

Let's proceed to step 16:
644 can be fit into 5520 8 times, resulting in a remainder of 368.
Put 8 as the next digit of the answer. 
Result so far: 102949.78571428
Subtracting 5152 from 5520 leaves us with 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

After the division, we end up with 102949.78571428 and a remainder of 3.68e-07.
