23097943 divided by 639 
We want to figure out the number of times 23097943 can be divided by 639.

Step 1:
2 divided by 639 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 639

Step 2:
If we divide 23 by 639, we get 0 and a remainder of 23.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 23 and we're left with 23.
Take the next digit (0) from the dividend and append it to 23, then repeat: 230 / 639

Going ahead to step 3:
639 can be fit into 230 0 times, resulting in a remainder of 230.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 230 leaves us with 230.
Bring next digit (9) of the dividend behind the 230 and repeat the process: 2309 / 639

Step 4:
639 goes into 2309 3 times with a remainder of 392.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 1917 from 2309 and we're left with 392.
Append the next digit (7) from the dividend to 392 and continue with: 3927 / 639

Going ahead to step 5:
639 goes into 3927 6 times with a remainder of 93.
The next digit of our result is 6. 
Result so far: 36.0
The remainder is 93 after subtracting 3834 from 3927.
Take the next digit (9) from the dividend and append it to 93, then repeat: 939 / 639

Step 6:
When dividing 939 by 639, we get 1 with a remainder of 300.
Put 1 as the next digit of the answer. 
Result so far: 361.0
Subtract 639 from 939 to get 300.
Bring next digit (4) of the dividend behind the 300 and repeat the process: 3004 / 639

Moving on to step 7:
The number 639 fits into 3004 4 times, leaving a remainder of 448.
The number 4 becomes the next digit in our result. 
Result so far: 3614.0
Subtracting 2556 from 3004 leaves us with 448.
Fetch the next digit (3) from the dividend, attach it to 448 and continue: 4483 / 639

Going ahead to step 8:
639 goes into 4483 7 times with a remainder of 10.
Write down 7 as next digit of the result. 
Result so far: 36147.0
Subtracting 4473 from 4483 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 9:
If we divide 100 by 639, we get 0 and a remainder of 100.
The number 0 becomes the next digit in our result. 
Result so far: 36147.0
If we subtract 0 from 100, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Moving on to step 10:
1000 divided by 639 is 1 with a remainder of 361.
Put 1 as the next digit of the answer. 
Result so far: 36147.01
If we take 639 away from 1000, we end up with 361.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3610, and continue the process.

Advancing to step 11:
639 goes into 3610 5 times with a remainder of 415.
Record the quotient 5 as the next digit in the result. 
Result so far: 36147.015
Subtract 3195 from 3610 to get 415.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4150, and continue the process.

Moving on to step 12:
When dividing 4150 by 639, we get 6 with a remainder of 316.
Record the quotient 6 as the next digit in the result. 
Result so far: 36147.0156
Subtract 3834 from 4150 to get 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

Going ahead to step 13:
639 goes into 3160 4 times with a remainder of 604.
The next digit of our result is 4. 
Result so far: 36147.01564
Subtract 2556 from 3160 to get 604.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6040, and continue the process.

Moving on to step 14:
The number 639 fits into 6040 9 times, leaving a remainder of 289.
Record the quotient 9 as the next digit in the result. 
Result so far: 36147.015649
The remainder is 289 after subtracting 5751 from 6040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2890, and continue the process.

Let's proceed to step 15:
639 goes into 2890 4 times with a remainder of 334.
Write down 4 as next digit of the result. 
Result so far: 36147.0156494
Deduct 2556 from 2890 and we're left with 334.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

On to step 16:
639 can be fit into 3340 5 times, resulting in a remainder of 145.
Put 5 as the next digit of the answer. 
Result so far: 36147.01564945
If we subtract 3195 from 3340, we get 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

The final result is 36147.01564945 with a remainder of 1.45e-07.
