We're dividing 644329 by 48 
We want to divide 644329 by 48.

Let's proceed to step 1:
48 can be fit into 6 0 times, resulting in a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 48

Let's proceed to step 2:
The number 48 fits into 64 1 times, leaving a remainder of 16.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 48 from 64, we get 16.
Append the next digit (4) from the dividend to 16 and continue with: 164 / 48

Going ahead to step 3:
164 divided by 48 is 3 with a remainder of 20.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
If we take 144 away from 164, we end up with 20.
Grab the next digit (3) from the dividend, add it to 20, then carry on: 203 / 48

Let's proceed to step 4:
If we divide 203 by 48, we get 4 and a remainder of 11.
Put 4 as the next digit of the answer. 
Result so far: 134.0
Deduct 192 from 203 and we're left with 11.
Include the next digit (2) from the dividend after 11, then repeat: 112 / 48

Advancing to step 5:
If we divide 112 by 48, we get 2 and a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 1342.0
Subtract 96 from 112 to get 16.
Grab the next digit (9) from the dividend, add it to 16, then carry on: 169 / 48

Step 6:
169 divided by 48 is 3 with a remainder of 25.
The next digit of our result is 3. 
Result so far: 13423.0
If we take 144 away from 169, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 7:
If we divide 250 by 48, we get 5 and a remainder of 10.
The next digit of our result is 5. 
Result so far: 13423.5
Subtract 240 from 250 to 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 8:
48 goes into 100 2 times with a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 13423.52
Subtract 96 from 100 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 9:
When dividing 40 by 48, we get 0 with a remainder of 40.
The next digit of our result is 0. 
Result so far: 13423.52
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 10:
48 goes into 400 8 times with a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 13423.5208
Subtract 384 from 400 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.

Let's proceed to step 11:
The number 48 fits into 160 3 times, leaving a remainder of 16.
The number 3 becomes the next digit in our result. 
Result so far: 13423.52083
The remainder is 16 after subtracting 144 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 12:
When dividing 160 by 48, we get 3 with a remainder of 16.
Write down 3 as next digit of the result. 
Result so far: 13423.520833
The remainder is 16 after subtracting 144 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The quotient of the division is 13423.520833, and the remainder is 1.6e-06.
