We look at the division of 65848412 by 644 
We want to figure out the number of times 65848412 can be divided by 644.

Step 1:
If we divide 6 by 644, 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 (5) from the dividend after 6, then repeat: 65 / 644

Step 2:
644 goes into 65 0 times with a remainder of 65.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 65, we get 65.
Fetch the next digit (8) from the dividend, attach it to 65 and continue: 658 / 644

Let's proceed to step 3:
644 can be fit into 658 1 times, resulting in a remainder of 14.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 644 from 658 and we're left with 14.
Fetch the next digit (4) from the dividend, attach it to 14 and continue: 144 / 644

Step 4:
The number 644 fits into 144 0 times, leaving a remainder of 144.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Deduct 0 from 144 and we're left with 144.
Take the next digit (8) from the dividend and append it to 144, then repeat: 1448 / 644

Going ahead to step 5:
If we divide 1448 by 644, we get 2 and a remainder of 160.
The number 2 becomes the next digit in our result. 
Result so far: 102.0
The remainder is 160 after subtracting 1288 from 1448.
Grab the next digit (4) from the dividend, add it to 160, then carry on: 1604 / 644

Advancing to step 6:
644 goes into 1604 2 times with a remainder of 316.
Use 2 as the next digit of our solution. 
Result so far: 1022.0
The remainder is 316 after subtracting 1288 from 1604.
Fetch the next digit (1) from the dividend, attach it to 316 and continue: 3161 / 644

Advancing to step 7:
3161 divided by 644 is 4 with a remainder of 585.
Put 4 as the next digit of the answer. 
Result so far: 10224.0
Subtract 2576 from 3161 to get 585.
Append the next digit (2) from the dividend to 585 and continue with: 5852 / 644

Advancing to step 8:
644 can be fit into 5852 9 times, resulting in a remainder of 56.
Put 9 as the next digit of the answer. 
Result so far: 102249.0
The remainder is 56 after subtracting 5796 from 5852.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 9:
The number 644 fits into 560 0 times, leaving a remainder of 560.
The number 0 becomes the next digit in our result. 
Result so far: 102249.0
If we take 0 away from 560, we end up with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Moving on to step 10:
The number 644 fits into 5600 8 times, leaving a remainder of 448.
Put 8 as the next digit of the answer. 
Result so far: 102249.08
If we subtract 5152 from 5600, we get 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Step 11:
When dividing 4480 by 644, we get 6 with a remainder of 616.
Put 6 as the next digit of the answer. 
Result so far: 102249.086
Subtract 3864 from 4480 to get 616.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6160, and continue the process.

Moving on to step 12:
If we divide 6160 by 644, we get 9 and a remainder of 364.
Put 9 as the next digit of the answer. 
Result so far: 102249.0869
If we take 5796 away from 6160, we end up with 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Advancing to step 13:
When dividing 3640 by 644, we get 5 with a remainder of 420.
The next digit of our result is 5. 
Result so far: 102249.08695
Subtract 3220 from 3640 to get 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Advancing to step 14:
When dividing 4200 by 644, we get 6 with a remainder of 336.
Write down 6 as next digit of the result. 
Result so far: 102249.086956
If we take 3864 away from 4200, we end up with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Let's proceed to step 15:
The number 644 fits into 3360 5 times, leaving a remainder of 140.
Record the quotient 5 as the next digit in the result. 
Result so far: 102249.0869565
Subtracting 3220 from 3360 leaves us with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Going ahead to step 16:
The number 644 fits into 1400 2 times, leaving a remainder of 112.
The next digit of our result is 2. 
Result so far: 102249.08695652
Subtract 1288 from 1400 to get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

The quotient of the division is 102249.08695652, and the remainder is 1.12e-07.
