Let's divide 644974 by 48
Let's see how many times 48 fits into 644974.

Advancing to step 1:
6 divided by 48 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 48

Let's proceed to step 2:
48 goes into 64 1 times with a remainder of 16.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 16 after subtracting 48 from 64.
Include the next digit (4) from the dividend after 16, then repeat: 164 / 48

Going ahead to step 3:
When dividing 164 by 48, we get 3 with a remainder of 20.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
The remainder is 20 after subtracting 144 from 164.
Grab the next digit (9) from the dividend, add it to 20, then carry on: 209 / 48

Step 4:
The number 48 fits into 209 4 times, leaving a remainder of 17.
The next digit of our result is 4. 
Result so far: 134.0
Deduct 192 from 209 and we're left with 17.
Append the next digit (7) from the dividend to 17 and continue with: 177 / 48

Going ahead to step 5:
When dividing 177 by 48, we get 3 with a remainder of 33.
Record the quotient 3 as the next digit in the result. 
Result so far: 1343.0
If we take 144 away from 177, we end up with 33.
Grab the next digit (4) from the dividend, add it to 33, then carry on: 334 / 48

Going ahead to step 6:
When dividing 334 by 48, we get 6 with a remainder of 46.
Use 6 as the next digit of our solution. 
Result so far: 13436.0
Deduct 288 from 334 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 7:
48 can be fit into 460 9 times, resulting in a remainder of 28.
Use 9 as the next digit of our solution. 
Result so far: 13436.9
The remainder is 28 after subtracting 432 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 8:
The number 48 fits into 280 5 times, leaving a remainder of 40.
Put 5 as the next digit of the answer. 
Result so far: 13436.95
If we take 240 away from 280, we end up 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.

Going ahead to step 9:
When dividing 400 by 48, we get 8 with a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 13436.958
If we subtract 384 from 400, we 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.

Advancing to step 10:
When dividing 160 by 48, we get 3 with a remainder of 16.
The next digit of our result is 3. 
Result so far: 13436.9583
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.

On to step 11:
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: 13436.95833
If we subtract 144 from 160, we 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.

Our division results in 13436.95833 with a remaining 1.6e-05.
