We divide 32686874 by 644
We want to divide 32686874 by 644.

Advancing to step 1:
When dividing 3 by 644, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (2) from the dividend after 3, then repeat: 32 / 644

Going ahead to step 2:
644 can be fit into 32 0 times, resulting in a remainder of 32.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 32, we end up with 32.
Take the next digit (6) from the dividend and append it to 32, then repeat: 326 / 644

Step 3:
If we divide 326 by 644, we get 0 and a remainder of 326.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 326, we get 326.
Include the next digit (8) from the dividend after 326, then repeat: 3268 / 644

On to step 4:
644 can be fit into 3268 5 times, resulting in a remainder of 48.
The next digit of our result is 5. 
Result so far: 5.0
The remainder is 48 after subtracting 3220 from 3268.
Append the next digit (6) from the dividend to 48 and continue with: 486 / 644

On to step 5:
When dividing 486 by 644, we get 0 with a remainder of 486.
The next digit of our result is 0. 
Result so far: 50.0
Subtracting 0 from 486 leaves us with 486.
Append the next digit (8) from the dividend to 486 and continue with: 4868 / 644

Let's proceed to step 6:
644 goes into 4868 7 times with a remainder of 360.
Write down 7 as next digit of the result. 
Result so far: 507.0
The remainder is 360 after subtracting 4508 from 4868.
Grab the next digit (7) from the dividend, add it to 360, then carry on: 3607 / 644

Let's proceed to step 7:
3607 divided by 644 is 5 with a remainder of 387.
Use 5 as the next digit of our solution. 
Result so far: 5075.0
Subtracting 3220 from 3607 leaves us with 387.
Fetch the next digit (4) from the dividend, attach it to 387 and continue: 3874 / 644

Going ahead to step 8:
The number 644 fits into 3874 6 times, leaving a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 50756.0
If we subtract 3864 from 3874, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 9:
The number 644 fits into 100 0 times, leaving a remainder of 100.
The number 0 becomes the next digit in our result. 
Result so far: 50756.0
Subtracting 0 from 100 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Step 10:
1000 divided by 644 is 1 with a remainder of 356.
Write down 1 as next digit of the result. 
Result so far: 50756.01
If we take 644 away from 1000, we end up with 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Advancing to step 11:
The number 644 fits into 3560 5 times, leaving a remainder of 340.
The next digit of our result is 5. 
Result so far: 50756.015
If we take 3220 away from 3560, we end up with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Step 12:
644 can be fit into 3400 5 times, resulting in a remainder of 180.
The next digit of our result is 5. 
Result so far: 50756.0155
The remainder is 180 after subtracting 3220 from 3400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

The final result is 50756.0155 with a remainder of 0.0018.
