We're dividing 38516423 by 639 
Our goal is to divide 38516423 by 639.

Let's proceed to step 1:
If we divide 3 by 639, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 639

Let's proceed to step 2:
38 divided by 639 is 0 with a remainder of 38.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 38, we get 38.
Append the next digit (5) from the dividend to 38 and continue with: 385 / 639

On to step 3:
639 goes into 385 0 times with a remainder of 385.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 385, we get 385.
Bring next digit (1) of the dividend behind the 385 and repeat the process: 3851 / 639

Step 4:
639 can be fit into 3851 6 times, resulting in a remainder of 17.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Deduct 3834 from 3851 and we're left with 17.
Take the next digit (6) from the dividend and append it to 17, then repeat: 176 / 639

Step 5:
If we divide 176 by 639, we get 0 and a remainder of 176.
Put 0 as the next digit of the answer. 
Result so far: 60.0
Subtract 0 from 176 to get 176.
Bring next digit (4) of the dividend behind the 176 and repeat the process: 1764 / 639

Moving on to step 6:
1764 divided by 639 is 2 with a remainder of 486.
Record the quotient 2 as the next digit in the result. 
Result so far: 602.0
The remainder is 486 after subtracting 1278 from 1764.
Grab the next digit (2) from the dividend, add it to 486, then carry on: 4862 / 639

Going ahead to step 7:
4862 divided by 639 is 7 with a remainder of 389.
Use 7 as the next digit of our solution. 
Result so far: 6027.0
If we take 4473 away from 4862, we end up with 389.
Bring next digit (3) of the dividend behind the 389 and repeat the process: 3893 / 639

On to step 8:
The number 639 fits into 3893 6 times, leaving a remainder of 59.
The number 6 becomes the next digit in our result. 
Result so far: 60276.0
If we subtract 3834 from 3893, we get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Moving on to step 9:
590 divided by 639 is 0 with a remainder of 590.
Record the quotient 0 as the next digit in the result. 
Result so far: 60276.0
Deduct 0 from 590 and we're left with 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

Advancing to step 10:
639 goes into 5900 9 times with a remainder of 149.
Put 9 as the next digit of the answer. 
Result so far: 60276.09
The remainder is 149 after subtracting 5751 from 5900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

Going ahead to step 11:
When dividing 1490 by 639, we get 2 with a remainder of 212.
Use 2 as the next digit of our solution. 
Result so far: 60276.092
The remainder is 212 after subtracting 1278 from 1490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Advancing to step 12:
If we divide 2120 by 639, we get 3 and a remainder of 203.
Write down 3 as next digit of the result. 
Result so far: 60276.0923
Subtract 1917 from 2120 to get 203.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2030, and continue the process.

Moving on to step 13:
If we divide 2030 by 639, we get 3 and a remainder of 113.
The number 3 becomes the next digit in our result. 
Result so far: 60276.09233
Deduct 1917 from 2030 and we're left with 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

The final outcome is 60276.09233, with a leftover of 0.000113.
