We're dividing 36954781 by 644 
Our goal is to divide 36954781 by 644.

Moving on to step 1:
If we divide 3 by 644, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Take the next digit (6) from the dividend and append it to 3, then repeat: 36 / 644

Advancing to step 2:
36 divided by 644 is 0 with a remainder of 36.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 36 and we're left with 36.
Append the next digit (9) from the dividend to 36 and continue with: 369 / 644

Step 3:
369 divided by 644 is 0 with a remainder of 369.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 369, we get 369.
Include the next digit (5) from the dividend after 369, then repeat: 3695 / 644

Let's proceed to step 4:
The number 644 fits into 3695 5 times, leaving a remainder of 475.
Write down 5 as next digit of the result. 
Result so far: 5.0
The remainder is 475 after subtracting 3220 from 3695.
Bring next digit (4) of the dividend behind the 475 and repeat the process: 4754 / 644

On to step 5:
644 can be fit into 4754 7 times, resulting in a remainder of 246.
The next digit of our result is 7. 
Result so far: 57.0
Subtracting 4508 from 4754 leaves us with 246.
Grab the next digit (7) from the dividend, add it to 246, then carry on: 2467 / 644

Advancing to step 6:
644 can be fit into 2467 3 times, resulting in a remainder of 535.
Write down 3 as next digit of the result. 
Result so far: 573.0
If we subtract 1932 from 2467, we get 535.
Fetch the next digit (8) from the dividend, attach it to 535 and continue: 5358 / 644

On to step 7:
644 can be fit into 5358 8 times, resulting in a remainder of 206.
The number 8 becomes the next digit in our result. 
Result so far: 5738.0
Deduct 5152 from 5358 and we're left with 206.
Take the next digit (1) from the dividend and append it to 206, then repeat: 2061 / 644

Step 8:
2061 divided by 644 is 3 with a remainder of 129.
The next digit of our result is 3. 
Result so far: 57383.0
Subtracting 1932 from 2061 leaves us with 129.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

On to step 9:
644 can be fit into 1290 2 times, resulting in a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 57383.2
If we subtract 1288 from 1290, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 10:
The number 644 fits into 20 0 times, leaving a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 57383.2
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 11:
The number 644 fits into 200 0 times, leaving a remainder of 200.
The number 0 becomes the next digit in our result. 
Result so far: 57383.2
Subtract 0 from 200 to get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

The final result is 57383.2 with a remainder of 0.02.
