We're dividing 48973773 by 638 
We're looking to find how many times 638 goes into 48973773.

Step 1:
When dividing 4 by 638, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Grab the next digit (8) from the dividend, add it to 4, then carry on: 48 / 638

On to step 2:
If we divide 48 by 638, we get 0 and a remainder of 48.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 48, we get 48.
Fetch the next digit (9) from the dividend, attach it to 48 and continue: 489 / 638

Step 3:
489 divided by 638 is 0 with a remainder of 489.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 489 leaves us with 489.
Append the next digit (7) from the dividend to 489 and continue with: 4897 / 638

On to step 4:
If we divide 4897 by 638, we get 7 and a remainder of 431.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we subtract 4466 from 4897, we get 431.
Include the next digit (3) from the dividend after 431, then repeat: 4313 / 638

Let's proceed to step 5:
When dividing 4313 by 638, we get 6 with a remainder of 485.
Use 6 as the next digit of our solution. 
Result so far: 76.0
Subtract 3828 from 4313 to get 485.
Grab the next digit (7) from the dividend, add it to 485, then carry on: 4857 / 638

Let's proceed to step 6:
When dividing 4857 by 638, we get 7 with a remainder of 391.
Put 7 as the next digit of the answer. 
Result so far: 767.0
Subtract 4466 from 4857 to get 391.
Append the next digit (7) from the dividend to 391 and continue with: 3917 / 638

On to step 7:
3917 divided by 638 is 6 with a remainder of 89.
Put 6 as the next digit of the answer. 
Result so far: 7676.0
The remainder is 89 after subtracting 3828 from 3917.
Take the next digit (3) from the dividend and append it to 89, then repeat: 893 / 638

Advancing to step 8:
893 divided by 638 is 1 with a remainder of 255.
Write down 1 as next digit of the result. 
Result so far: 76761.0
The remainder is 255 after subtracting 638 from 893.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

On to step 9:
638 can be fit into 2550 3 times, resulting in a remainder of 636.
The number 3 becomes the next digit in our result. 
Result so far: 76761.3
The remainder is 636 after subtracting 1914 from 2550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6360, and continue the process.

Let's proceed to step 10:
638 can be fit into 6360 9 times, resulting in a remainder of 618.
The next digit of our result is 9. 
Result so far: 76761.39
Deduct 5742 from 6360 and we're left with 618.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6180, and continue the process.

Moving on to step 11:
6180 divided by 638 is 9 with a remainder of 438.
Use 9 as the next digit of our solution. 
Result so far: 76761.399
The remainder is 438 after subtracting 5742 from 6180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4380, and continue the process.

The quotient of the division is 76761.399, and the remainder is 0.0438.
