Let's divide 37258764 by 644
We want to figure out the number of times 37258764 can be divided by 644.

Advancing to step 1:
3 divided by 644 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 644

On to step 2:
If we divide 37 by 644, we get 0 and a remainder of 37.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 37 after subtracting 0 from 37.
Include the next digit (2) from the dividend after 37, then repeat: 372 / 644

Let's proceed to step 3:
644 can be fit into 372 0 times, resulting in a remainder of 372.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 372 to get 372.
Fetch the next digit (5) from the dividend, attach it to 372 and continue: 3725 / 644

Step 4:
3725 divided by 644 is 5 with a remainder of 505.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we take 3220 away from 3725, we end up with 505.
Grab the next digit (8) from the dividend, add it to 505, then carry on: 5058 / 644

Let's proceed to step 5:
When dividing 5058 by 644, we get 7 with a remainder of 550.
The next digit of our result is 7. 
Result so far: 57.0
The remainder is 550 after subtracting 4508 from 5058.
Take the next digit (7) from the dividend and append it to 550, then repeat: 5507 / 644

Moving on to step 6:
5507 divided by 644 is 8 with a remainder of 355.
The number 8 becomes the next digit in our result. 
Result so far: 578.0
Deduct 5152 from 5507 and we're left with 355.
Bring next digit (6) of the dividend behind the 355 and repeat the process: 3556 / 644

Moving on to step 7:
When dividing 3556 by 644, we get 5 with a remainder of 336.
The next digit of our result is 5. 
Result so far: 5785.0
Deduct 3220 from 3556 and we're left with 336.
Take the next digit (4) from the dividend and append it to 336, then repeat: 3364 / 644

Step 8:
3364 divided by 644 is 5 with a remainder of 144.
Use 5 as the next digit of our solution. 
Result so far: 57855.0
Subtract 3220 from 3364 to get 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Going ahead to step 9:
If we divide 1440 by 644, we get 2 and a remainder of 152.
Record the quotient 2 as the next digit in the result. 
Result so far: 57855.2
Deduct 1288 from 1440 and we're left with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Moving on to step 10:
If we divide 1520 by 644, we get 2 and a remainder of 232.
Use 2 as the next digit of our solution. 
Result so far: 57855.22
Subtracting 1288 from 1520 leaves us with 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

The quotient of the division is 57855.22, and the remainder is 0.232.
