We're dividing 208438 by 48 
Let's see how many times 48 fits into 208438.

Step 1:
If we divide 2 by 48, we get 0 and a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 48

Let's proceed to step 2:
The number 48 fits into 20 0 times, leaving a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 20 to get 20.
Bring next digit (8) of the dividend behind the 20 and repeat the process: 208 / 48

Step 3:
When dividing 208 by 48, we get 4 with a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 192 away from 208, we end up with 16.
Bring next digit (4) of the dividend behind the 16 and repeat the process: 164 / 48

Advancing to step 4:
48 goes into 164 3 times with a remainder of 20.
Put 3 as the next digit of the answer. 
Result so far: 43.0
The remainder is 20 after subtracting 144 from 164.
Bring next digit (3) of the dividend behind the 20 and repeat the process: 203 / 48

On to step 5:
The number 48 fits into 203 4 times, leaving a remainder of 11.
Write down 4 as next digit of the result. 
Result so far: 434.0
Deduct 192 from 203 and we're left with 11.
Take the next digit (8) from the dividend and append it to 11, then repeat: 118 / 48

Let's proceed to step 6:
When dividing 118 by 48, we get 2 with a remainder of 22.
Write down 2 as next digit of the result. 
Result so far: 4342.0
If we take 96 away from 118, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 7:
The number 48 fits into 220 4 times, leaving a remainder of 28.
Record the quotient 4 as the next digit in the result. 
Result so far: 4342.4
Deduct 192 from 220 and we're left 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.

Advancing to step 8:
If we divide 280 by 48, we get 5 and a remainder of 40.
Use 5 as the next digit of our solution. 
Result so far: 4342.45
Deduct 240 from 280 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.

Step 9:
When dividing 400 by 48, we get 8 with a remainder of 16.
The next digit of our result is 8. 
Result so far: 4342.458
If we take 384 away from 400, we end up 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.

On to step 10:
When dividing 160 by 48, we get 3 with a remainder of 16.
The number 3 becomes the next digit in our result. 
Result so far: 4342.4583
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.

On to step 11:
48 can be fit into 160 3 times, resulting in a remainder of 16.
Record the quotient 3 as the next digit in the result. 
Result so far: 4342.45833
If we take 144 away from 160, we end up 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.

The final result is 4342.45833 with a remainder of 1.6e-05.
