202139 ÷ 48 
Our goal is to divide 202139 by 48.

Let's proceed to step 1:
2 divided by 48 is 0 with 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

Advancing to step 2:
If we divide 20 by 48, we get 0 and a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 20 and we're left with 20.
Append the next digit (2) from the dividend to 20 and continue with: 202 / 48

On to step 3:
The number 48 fits into 202 4 times, leaving a remainder of 10.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we subtract 192 from 202, we get 10.
Include the next digit (1) from the dividend after 10, then repeat: 101 / 48

Moving on to step 4:
48 goes into 101 2 times with a remainder of 5.
The next digit of our result is 2. 
Result so far: 42.0
Deduct 96 from 101 and we're left with 5.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 48

On to step 5:
48 goes into 53 1 times with a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 421.0
If we take 48 away from 53, we end up with 5.
Grab the next digit (9) from the dividend, add it to 5, then carry on: 59 / 48

Step 6:
48 goes into 59 1 times with a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 4211.0
Subtracting 48 from 59 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 7:
When dividing 110 by 48, we get 2 with a remainder of 14.
Put 2 as the next digit of the answer. 
Result so far: 4211.2
If we take 96 away from 110, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 8:
When dividing 140 by 48, we get 2 with a remainder of 44.
The number 2 becomes the next digit in our result. 
Result so far: 4211.22
If we subtract 96 from 140, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Our division results in 4211.22 with a remaining 0.044.
