41254012 divided by 644 
Let's see how many times 644 fits into 41254012.

Going ahead to step 1:
When dividing 4 by 644, we get 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Take the next digit (1) from the dividend and append it to 4, then repeat: 41 / 644

On to step 2:
When dividing 41 by 644, we get 0 with a remainder of 41.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 41 to get 41.
Fetch the next digit (2) from the dividend, attach it to 41 and continue: 412 / 644

Going ahead to step 3:
When dividing 412 by 644, we get 0 with a remainder of 412.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 412 after subtracting 0 from 412.
Append the next digit (5) from the dividend to 412 and continue with: 4125 / 644

Step 4:
644 can be fit into 4125 6 times, resulting in a remainder of 261.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
The remainder is 261 after subtracting 3864 from 4125.
Grab the next digit (4) from the dividend, add it to 261, then carry on: 2614 / 644

On to step 5:
644 can be fit into 2614 4 times, resulting in a remainder of 38.
The number 4 becomes the next digit in our result. 
Result so far: 64.0
The remainder is 38 after subtracting 2576 from 2614.
Fetch the next digit (0) from the dividend, attach it to 38 and continue: 380 / 644

Going ahead to step 6:
380 divided by 644 is 0 with a remainder of 380.
The next digit of our result is 0. 
Result so far: 640.0
Deduct 0 from 380 and we're left with 380.
Append the next digit (1) from the dividend to 380 and continue with: 3801 / 644

Advancing to step 7:
When dividing 3801 by 644, we get 5 with a remainder of 581.
The next digit of our result is 5. 
Result so far: 6405.0
The remainder is 581 after subtracting 3220 from 3801.
Grab the next digit (2) from the dividend, add it to 581, then carry on: 5812 / 644

Step 8:
644 goes into 5812 9 times with a remainder of 16.
Put 9 as the next digit of the answer. 
Result so far: 64059.0
Deduct 5796 from 5812 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 9:
The number 644 fits into 160 0 times, leaving a remainder of 160.
Use 0 as the next digit of our solution. 
Result so far: 64059.0
Subtracting 0 from 160 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Going ahead to step 10:
If we divide 1600 by 644, we get 2 and a remainder of 312.
Put 2 as the next digit of the answer. 
Result so far: 64059.02
Deduct 1288 from 1600 and we're left with 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

On to step 11:
When dividing 3120 by 644, we get 4 with a remainder of 544.
Use 4 as the next digit of our solution. 
Result so far: 64059.024
Subtracting 2576 from 3120 leaves us with 544.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

Going ahead to step 12:
644 goes into 5440 8 times with a remainder of 288.
Record the quotient 8 as the next digit in the result. 
Result so far: 64059.0248
If we take 5152 away from 5440, we end up with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Moving on to step 13:
644 goes into 2880 4 times with a remainder of 304.
Record the quotient 4 as the next digit in the result. 
Result so far: 64059.02484
Deduct 2576 from 2880 and we're left with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Step 14:
When dividing 3040 by 644, we get 4 with a remainder of 464.
Put 4 as the next digit of the answer. 
Result so far: 64059.024844
Subtract 2576 from 3040 to get 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

The final outcome is 64059.024844, with a leftover of 4.64e-05.
