Let's divide 15390083 by 756
Our goal is to divide 15390083 by 756.

Let's proceed to step 1:
If we divide 1 by 756, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 756

Going ahead to step 2:
15 divided by 756 is 0 with a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Fetch the next digit (3) from the dividend, attach it to 15 and continue: 153 / 756

On to step 3:
153 divided by 756 is 0 with a remainder of 153.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 153, we get 153.
Take the next digit (9) from the dividend and append it to 153, then repeat: 1539 / 756

Moving on to step 4:
756 goes into 1539 2 times with a remainder of 27.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 1512 from 1539 to get 27.
Take the next digit (0) from the dividend and append it to 27, then repeat: 270 / 756

Moving on to step 5:
756 can be fit into 270 0 times, resulting in a remainder of 270.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
Subtract 0 from 270 to get 270.
Take the next digit (0) from the dividend and append it to 270, then repeat: 2700 / 756

Going ahead to step 6:
When dividing 2700 by 756, we get 3 with a remainder of 432.
The number 3 becomes the next digit in our result. 
Result so far: 203.0
If we subtract 2268 from 2700, we get 432.
Append the next digit (8) from the dividend to 432 and continue with: 4328 / 756

Going ahead to step 7:
4328 divided by 756 is 5 with a remainder of 548.
The next digit of our result is 5. 
Result so far: 2035.0
Deduct 3780 from 4328 and we're left with 548.
Take the next digit (3) from the dividend and append it to 548, then repeat: 5483 / 756

Going ahead to step 8:
5483 divided by 756 is 7 with a remainder of 191.
Write down 7 as next digit of the result. 
Result so far: 20357.0
Deduct 5292 from 5483 and we're left with 191.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1910, and continue the process.

On to step 9:
If we divide 1910 by 756, we get 2 and a remainder of 398.
Write down 2 as next digit of the result. 
Result so far: 20357.2
If we subtract 1512 from 1910, we get 398.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3980, and continue the process.

Let's proceed to step 10:
When dividing 3980 by 756, we get 5 with a remainder of 200.
The number 5 becomes the next digit in our result. 
Result so far: 20357.25
Subtracting 3780 from 3980 leaves us with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Advancing to step 11:
The number 756 fits into 2000 2 times, leaving a remainder of 488.
The next digit of our result is 2. 
Result so far: 20357.252
If we take 1512 away from 2000, we end up with 488.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

Moving on to step 12:
756 goes into 4880 6 times with a remainder of 344.
Use 6 as the next digit of our solution. 
Result so far: 20357.2526
Subtracting 4536 from 4880 leaves us with 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Let's proceed to step 13:
If we divide 3440 by 756, we get 4 and a remainder of 416.
Use 4 as the next digit of our solution. 
Result so far: 20357.25264
Deduct 3024 from 3440 and we're left with 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Advancing to step 14:
756 goes into 4160 5 times with a remainder of 380.
The next digit of our result is 5. 
Result so far: 20357.252645
Subtract 3780 from 4160 to get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Advancing to step 15:
756 goes into 3800 5 times with a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 20357.2526455
Deduct 3780 from 3800 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final outcome is 20357.2526455, with a leftover of 2e-07.
