We're dividing 378921 by 32 
We want to divide 378921 by 32.

Let's proceed to step 1:
The number 32 fits into 3 0 times, leaving 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.
Append the next digit (7) from the dividend to 3 and continue with: 37 / 32

Step 2:
37 divided by 32 is 1 with a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 32 from 37 leaves us with 5.
Grab the next digit (8) from the dividend, add it to 5, then carry on: 58 / 32

Going ahead to step 3:
The number 32 fits into 58 1 times, leaving a remainder of 26.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Subtract 32 from 58 to get 26.
Include the next digit (9) from the dividend after 26, then repeat: 269 / 32

Advancing to step 4:
32 can be fit into 269 8 times, resulting in a remainder of 13.
Put 8 as the next digit of the answer. 
Result so far: 118.0
Subtract 256 from 269 to get 13.
Take the next digit (2) from the dividend and append it to 13, then repeat: 132 / 32

Moving on to step 5:
When dividing 132 by 32, we get 4 with a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 1184.0
If we subtract 128 from 132, we get 4.
Bring next digit (1) of the dividend behind the 4 and repeat the process: 41 / 32

Moving on to step 6:
41 divided by 32 is 1 with a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 11841.0
If we subtract 32 from 41, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 7:
32 can be fit into 90 2 times, resulting in a remainder of 26.
The next digit of our result is 2. 
Result so far: 11841.2
If we subtract 64 from 90, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 8:
32 can be fit into 260 8 times, resulting in a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 11841.28
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.

On to step 9:
32 can be fit into 40 1 times, resulting in a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 11841.281
The remainder is 8 after subtracting 32 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 10:
The number 32 fits into 80 2 times, leaving a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 11841.2812
Subtract 64 from 80 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 11:
160 divided by 32 is 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 11841.28125
Deduct 160 from 160 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.

Advancing to step 12:
0 divided by 32 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 11841.28125
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 13:
If we divide 0 by 32, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 11841.28125
The remainder is 0 after subtracting 0 from 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 11841.28125, with a leftover of 0.0.
