Let's divide 638189 by 48
We're looking to find how many times 48 goes into 638189.

On 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.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 48

Going ahead to step 2:
When dividing 63 by 48, we get 1 with a remainder of 15.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 48 from 63, we get 15.
Take the next digit (8) from the dividend and append it to 15, then repeat: 158 / 48

Advancing to step 3:
When dividing 158 by 48, we get 3 with a remainder of 14.
Put 3 as the next digit of the answer. 
Result so far: 13.0
Deduct 144 from 158 and we're left with 14.
Append the next digit (1) from the dividend to 14 and continue with: 141 / 48

Let's proceed to step 4:
48 goes into 141 2 times with a remainder of 45.
Use 2 as the next digit of our solution. 
Result so far: 132.0
Subtract 96 from 141 to get 45.
Include the next digit (8) from the dividend after 45, then repeat: 458 / 48

Let's proceed to step 5:
The number 48 fits into 458 9 times, leaving a remainder of 26.
Record the quotient 9 as the next digit in the result. 
Result so far: 1329.0
Deduct 432 from 458 and we're left with 26.
Take the next digit (9) from the dividend and append it to 26, then repeat: 269 / 48

Let's proceed to step 6:
48 can be fit into 269 5 times, resulting in a remainder of 29.
The next digit of our result is 5. 
Result so far: 13295.0
Subtracting 240 from 269 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 7:
48 goes into 290 6 times with a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 13295.6
If we take 288 away from 290, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 8:
48 goes into 20 0 times with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 13295.6
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 9:
If we divide 200 by 48, we get 4 and a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 13295.604
If we take 192 away from 200, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 10:
80 divided by 48 is 1 with a remainder of 32.
Write down 1 as next digit of the result. 
Result so far: 13295.6041
Subtracting 48 from 80 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 11:
48 goes into 320 6 times with a remainder of 32.
Use 6 as the next digit of our solution. 
Result so far: 13295.60416
If we subtract 288 from 320, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 12:
320 divided by 48 is 6 with a remainder of 32.
Put 6 as the next digit of the answer. 
Result so far: 13295.604166
Deduct 288 from 320 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

After the division, we end up with 13295.604166 and a remainder of 3.2e-06.
