We divide 40012782 by 644
We want to figure out the number of times 40012782 can be divided by 644.

Advancing to step 1:
When dividing 4 by 644, we get 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 644

Advancing to step 2:
If we divide 40 by 644, we get 0 and a remainder of 40.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 40, we end up with 40.
Take the next digit (0) from the dividend and append it to 40, then repeat: 400 / 644

Advancing to step 3:
The number 644 fits into 400 0 times, leaving a remainder of 400.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 400 after subtracting 0 from 400.
Fetch the next digit (1) from the dividend, attach it to 400 and continue: 4001 / 644

Going ahead to step 4:
644 goes into 4001 6 times with a remainder of 137.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Deduct 3864 from 4001 and we're left with 137.
Bring next digit (2) of the dividend behind the 137 and repeat the process: 1372 / 644

Moving on to step 5:
The number 644 fits into 1372 2 times, leaving a remainder of 84.
Use 2 as the next digit of our solution. 
Result so far: 62.0
Deduct 1288 from 1372 and we're left with 84.
Take the next digit (7) from the dividend and append it to 84, then repeat: 847 / 644

Advancing to step 6:
644 goes into 847 1 times with a remainder of 203.
Record the quotient 1 as the next digit in the result. 
Result so far: 621.0
Subtract 644 from 847 to get 203.
Fetch the next digit (8) from the dividend, attach it to 203 and continue: 2038 / 644

On to step 7:
When dividing 2038 by 644, we get 3 with a remainder of 106.
The number 3 becomes the next digit in our result. 
Result so far: 6213.0
If we take 1932 away from 2038, we end up with 106.
Grab the next digit (2) from the dividend, add it to 106, then carry on: 1062 / 644

Moving on to step 8:
644 can be fit into 1062 1 times, resulting in a remainder of 418.
Use 1 as the next digit of our solution. 
Result so far: 62131.0
Subtract 644 from 1062 to get 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

Moving on to step 9:
4180 divided by 644 is 6 with a remainder of 316.
The number 6 becomes the next digit in our result. 
Result so far: 62131.6
The remainder is 316 after subtracting 3864 from 4180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

On to step 10:
When dividing 3160 by 644, we get 4 with a remainder of 584.
Use 4 as the next digit of our solution. 
Result so far: 62131.64
Subtract 2576 from 3160 to get 584.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5840, and continue the process.

Step 11:
If we divide 5840 by 644, we get 9 and a remainder of 44.
Record the quotient 9 as the next digit in the result. 
Result so far: 62131.649
Deduct 5796 from 5840 and we're left 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 12:
644 can be fit into 440 0 times, resulting in a remainder of 440.
The number 0 becomes the next digit in our result. 
Result so far: 62131.649
Deduct 0 from 440 and we're left with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

On to step 13:
644 goes into 4400 6 times with a remainder of 536.
Use 6 as the next digit of our solution. 
Result so far: 62131.64906
If we take 3864 away from 4400, we end up with 536.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5360, and continue the process.

On to step 14:
5360 divided by 644 is 8 with a remainder of 208.
Use 8 as the next digit of our solution. 
Result so far: 62131.649068
The remainder is 208 after subtracting 5152 from 5360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Let's proceed to step 15:
When dividing 2080 by 644, we get 3 with a remainder of 148.
The number 3 becomes the next digit in our result. 
Result so far: 62131.6490683
If we subtract 1932 from 2080, we get 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Step 16:
When dividing 1480 by 644, we get 2 with a remainder of 192.
The number 2 becomes the next digit in our result. 
Result so far: 62131.64906832
If we take 1288 away from 1480, we end up with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Our division results in 62131.64906832 with a remaining 1.92e-07.
