Let's divide 19962418 by 639
We're looking to find how many times 639 goes into 19962418.

Moving on to step 1:
If we divide 1 by 639, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 639

Moving on to step 2:
639 can be fit into 19 0 times, resulting in a remainder of 19.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 19 after subtracting 0 from 19.
Grab the next digit (9) from the dividend, add it to 19, then carry on: 199 / 639

Going ahead to step 3:
If we divide 199 by 639, we get 0 and a remainder of 199.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 199 to get 199.
Include the next digit (6) from the dividend after 199, then repeat: 1996 / 639

Step 4:
639 goes into 1996 3 times with a remainder of 79.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 1917 from 1996 leaves us with 79.
Grab the next digit (2) from the dividend, add it to 79, then carry on: 792 / 639

Advancing to step 5:
639 goes into 792 1 times with a remainder of 153.
The number 1 becomes the next digit in our result. 
Result so far: 31.0
Subtract 639 from 792 to get 153.
Include the next digit (4) from the dividend after 153, then repeat: 1534 / 639

Step 6:
If we divide 1534 by 639, we get 2 and a remainder of 256.
The next digit of our result is 2. 
Result so far: 312.0
If we subtract 1278 from 1534, we get 256.
Fetch the next digit (1) from the dividend, attach it to 256 and continue: 2561 / 639

Let's proceed to step 7:
When dividing 2561 by 639, we get 4 with a remainder of 5.
Write down 4 as next digit of the result. 
Result so far: 3124.0
Subtract 2556 from 2561 to get 5.
Fetch the next digit (8) from the dividend, attach it to 5 and continue: 58 / 639

Going ahead to step 8:
When dividing 58 by 639, we get 0 with a remainder of 58.
Put 0 as the next digit of the answer. 
Result so far: 31240.0
Deduct 0 from 58 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Going ahead to step 9:
When dividing 580 by 639, we get 0 with a remainder of 580.
Write down 0 as next digit of the result. 
Result so far: 31240.0
Subtracting 0 from 580 leaves us with 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Going ahead to step 10:
The number 639 fits into 5800 9 times, leaving a remainder of 49.
Put 9 as the next digit of the answer. 
Result so far: 31240.09
If we subtract 5751 from 5800, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Advancing to step 11:
The number 639 fits into 490 0 times, leaving a remainder of 490.
The next digit of our result is 0. 
Result so far: 31240.09
If we subtract 0 from 490, we get 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Let's proceed to step 12:
639 goes into 4900 7 times with a remainder of 427.
Write down 7 as next digit of the result. 
Result so far: 31240.0907
The remainder is 427 after subtracting 4473 from 4900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4270, and continue the process.

Advancing to step 13:
639 goes into 4270 6 times with a remainder of 436.
The number 6 becomes the next digit in our result. 
Result so far: 31240.09076
Subtract 3834 from 4270 to get 436.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4360, and continue the process.

Let's proceed to step 14:
If we divide 4360 by 639, we get 6 and a remainder of 526.
The number 6 becomes the next digit in our result. 
Result so far: 31240.090766
Deduct 3834 from 4360 and we're left with 526.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5260, and continue the process.

Our division results in 31240.090766 with a remaining 5.26e-05.
