We look at the division of 23727303 by 645 
We want to divide 23727303 by 645.

Going ahead to step 1:
2 divided by 645 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 645

Let's proceed to step 2:
If we divide 23 by 645, we get 0 and a remainder of 23.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 23 and we're left with 23.
Append the next digit (7) from the dividend to 23 and continue with: 237 / 645

Step 3:
645 can be fit into 237 0 times, resulting in a remainder of 237.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 237, we end up with 237.
Take the next digit (2) from the dividend and append it to 237, then repeat: 2372 / 645

On to step 4:
2372 divided by 645 is 3 with a remainder of 437.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtract 1935 from 2372 to get 437.
Append the next digit (7) from the dividend to 437 and continue with: 4377 / 645

On to step 5:
When dividing 4377 by 645, we get 6 with a remainder of 507.
Write down 6 as next digit of the result. 
Result so far: 36.0
If we take 3870 away from 4377, we end up with 507.
Include the next digit (3) from the dividend after 507, then repeat: 5073 / 645

On to step 6:
645 can be fit into 5073 7 times, resulting in a remainder of 558.
The next digit of our result is 7. 
Result so far: 367.0
Subtracting 4515 from 5073 leaves us with 558.
Fetch the next digit (0) from the dividend, attach it to 558 and continue: 5580 / 645

On to step 7:
When dividing 5580 by 645, we get 8 with a remainder of 420.
Put 8 as the next digit of the answer. 
Result so far: 3678.0
Deduct 5160 from 5580 and we're left with 420.
Fetch the next digit (3) from the dividend, attach it to 420 and continue: 4203 / 645

Advancing to step 8:
645 can be fit into 4203 6 times, resulting in a remainder of 333.
Record the quotient 6 as the next digit in the result. 
Result so far: 36786.0
If we take 3870 away from 4203, we end up with 333.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3330, and continue the process.

Advancing to step 9:
If we divide 3330 by 645, we get 5 and a remainder of 105.
Write down 5 as next digit of the result. 
Result so far: 36786.5
The remainder is 105 after subtracting 3225 from 3330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Advancing to step 10:
The number 645 fits into 1050 1 times, leaving a remainder of 405.
The number 1 becomes the next digit in our result. 
Result so far: 36786.51
Subtract 645 from 1050 to get 405.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4050, and continue the process.

Step 11:
645 can be fit into 4050 6 times, resulting in a remainder of 180.
The number 6 becomes the next digit in our result. 
Result so far: 36786.516
The remainder is 180 after subtracting 3870 from 4050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Advancing to step 12:
When dividing 1800 by 645, we get 2 with a remainder of 510.
Record the quotient 2 as the next digit in the result. 
Result so far: 36786.5162
If we take 1290 away from 1800, we end up with 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

Moving on to step 13:
When dividing 5100 by 645, we get 7 with a remainder of 585.
The next digit of our result is 7. 
Result so far: 36786.51627
The remainder is 585 after subtracting 4515 from 5100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5850, and continue the process.

Going ahead to step 14:
5850 divided by 645 is 9 with a remainder of 45.
The next digit of our result is 9. 
Result so far: 36786.516279
Subtracting 5805 from 5850 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 15:
645 goes into 450 0 times with a remainder of 450.
Use 0 as the next digit of our solution. 
Result so far: 36786.516279
The remainder is 450 after subtracting 0 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Moving on to step 16:
645 can be fit into 4500 6 times, resulting in a remainder of 630.
The number 6 becomes the next digit in our result. 
Result so far: 36786.51627906
Subtracting 3870 from 4500 leaves us with 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

The final outcome is 36786.51627906, with a leftover of 6.3e-07.
