50388723 divided by 638 
Our goal is to divide 50388723 by 638.

Step 1:
If we divide 5 by 638, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Bring next digit (0) of the dividend behind the 5 and repeat the process: 50 / 638

Moving on to step 2:
638 can be fit into 50 0 times, resulting in a remainder of 50.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 50, we get 50.
Grab the next digit (3) from the dividend, add it to 50, then carry on: 503 / 638

Step 3:
When dividing 503 by 638, we get 0 with a remainder of 503.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 503, we end up with 503.
Bring next digit (8) of the dividend behind the 503 and repeat the process: 5038 / 638

On to step 4:
638 goes into 5038 7 times with a remainder of 572.
The next digit of our result is 7. 
Result so far: 7.0
Deduct 4466 from 5038 and we're left with 572.
Include the next digit (8) from the dividend after 572, then repeat: 5728 / 638

Going ahead to step 5:
638 goes into 5728 8 times with a remainder of 624.
Record the quotient 8 as the next digit in the result. 
Result so far: 78.0
If we take 5104 away from 5728, we end up with 624.
Include the next digit (7) from the dividend after 624, then repeat: 6247 / 638

Going ahead to step 6:
6247 divided by 638 is 9 with a remainder of 505.
Record the quotient 9 as the next digit in the result. 
Result so far: 789.0
If we take 5742 away from 6247, we end up with 505.
Grab the next digit (2) from the dividend, add it to 505, then carry on: 5052 / 638

Advancing to step 7:
When dividing 5052 by 638, we get 7 with a remainder of 586.
Use 7 as the next digit of our solution. 
Result so far: 7897.0
If we subtract 4466 from 5052, we get 586.
Include the next digit (3) from the dividend after 586, then repeat: 5863 / 638

On to step 8:
When dividing 5863 by 638, we get 9 with a remainder of 121.
The next digit of our result is 9. 
Result so far: 78979.0
The remainder is 121 after subtracting 5742 from 5863.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Moving on to step 9:
1210 divided by 638 is 1 with a remainder of 572.
The next digit of our result is 1. 
Result so far: 78979.1
Subtracting 638 from 1210 leaves us with 572.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5720, and continue the process.

Let's proceed to step 10:
638 can be fit into 5720 8 times, resulting in a remainder of 616.
Write down 8 as next digit of the result. 
Result so far: 78979.18
Subtract 5104 from 5720 to get 616.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6160, and continue the process.

Step 11:
When dividing 6160 by 638, we get 9 with a remainder of 418.
Put 9 as the next digit of the answer. 
Result so far: 78979.189
If we subtract 5742 from 6160, we get 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

Step 12:
638 goes into 4180 6 times with a remainder of 352.
Put 6 as the next digit of the answer. 
Result so far: 78979.1896
Subtracting 3828 from 4180 leaves us with 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Moving on to step 13:
638 goes into 3520 5 times with a remainder of 330.
Use 5 as the next digit of our solution. 
Result so far: 78979.18965
If we take 3190 away from 3520, we end up with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Let's proceed to step 14:
3300 divided by 638 is 5 with a remainder of 110.
Record the quotient 5 as the next digit in the result. 
Result so far: 78979.189655
The remainder is 110 after subtracting 3190 from 3300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

The final outcome is 78979.189655, with a leftover of 1.1e-05.
