645146 divided by 32 
Let's see how many times 32 fits into 645146.

Let's proceed to step 1:
6 divided by 32 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 32

Moving on to step 2:
32 goes into 64 2 times with a remainder of 0.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 64 from 64 and we're left with 0.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 32

Advancing to step 3:
32 can be fit into 5 0 times, resulting in a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
If we subtract 0 from 5, we get 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 32

Let's proceed to step 4:
When dividing 51 by 32, we get 1 with a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 201.0
If we subtract 32 from 51, we get 19.
Grab the next digit (4) from the dividend, add it to 19, then carry on: 194 / 32

Let's proceed to step 5:
32 can be fit into 194 6 times, resulting in a remainder of 2.
The next digit of our result is 6. 
Result so far: 2016.0
If we take 192 away from 194, we end up with 2.
Append the next digit (6) from the dividend to 2 and continue with: 26 / 32

Step 6:
32 can be fit into 26 0 times, resulting in a remainder of 26.
The number 0 becomes the next digit in our result. 
Result so far: 20160.0
Deduct 0 from 26 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 7:
If we divide 260 by 32, we get 8 and a remainder of 4.
The next digit of our result is 8. 
Result so far: 20160.8
Deduct 256 from 260 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 8:
40 divided by 32 is 1 with a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 20160.81
Subtracting 32 from 40 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 9:
32 goes into 80 2 times with a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 20160.812
Subtracting 64 from 80 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.

Advancing to step 10:
If we divide 160 by 32, we get 5 and a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 20160.8125
Subtract 160 from 160 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 11:
When dividing 0 by 32, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 20160.8125
If we subtract 0 from 0, we 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.

Step 12:
32 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 20160.8125
Deduct 0 from 0 and we're left 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 final outcome is 20160.8125, with a leftover of 0.0.
