We look at the division of 644375 by 32 
We want to figure out the number of times 644375 can be divided by 32.

Moving on to step 1:
6 divided by 32 is 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 32

Let's proceed to step 2:
32 goes into 64 2 times with a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 64 from 64, we get 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 32

Advancing to step 3:
32 goes into 4 0 times with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 20.0
Subtracting 0 from 4 leaves us with 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 32

Let's proceed to step 4:
The number 32 fits into 43 1 times, leaving a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 201.0
Subtracting 32 from 43 leaves us with 11.
Bring next digit (7) of the dividend behind the 11 and repeat the process: 117 / 32

On to step 5:
32 can be fit into 117 3 times, resulting in a remainder of 21.
Put 3 as the next digit of the answer. 
Result so far: 2013.0
The remainder is 21 after subtracting 96 from 117.
Append the next digit (5) from the dividend to 21 and continue with: 215 / 32

Advancing to step 6:
If we divide 215 by 32, we get 6 and a remainder of 23.
The next digit of our result is 6. 
Result so far: 20136.0
Subtract 192 from 215 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 7:
The number 32 fits into 230 7 times, leaving a remainder of 6.
The number 7 becomes the next digit in our result. 
Result so far: 20136.7
Deduct 224 from 230 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 8:
32 goes into 60 1 times with a remainder of 28.
Record the quotient 1 as the next digit in the result. 
Result so far: 20136.71
If we take 32 away from 60, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 9:
32 goes into 280 8 times with a remainder of 24.
Write down 8 as next digit of the result. 
Result so far: 20136.718
If we subtract 256 from 280, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 10:
32 goes into 240 7 times with a remainder of 16.
The number 7 becomes the next digit in our result. 
Result so far: 20136.7187
Subtracting 224 from 240 leaves us 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.

Let's proceed to step 11:
32 goes into 160 5 times with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 20136.71875
The remainder is 0 after subtracting 160 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 12:
When dividing 0 by 32, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 20136.71875
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 13:
32 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 20136.71875
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 20136.71875, and the remainder is 0.0.
