Let's divide 16390640 by 757
Our goal is to divide 16390640 by 757.

On to step 1:
757 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 757

Step 2:
16 divided by 757 is 0 with a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 16 to get 16.
Include the next digit (3) from the dividend after 16, then repeat: 163 / 757

Moving on to step 3:
757 can be fit into 163 0 times, resulting in a remainder of 163.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 163 after subtracting 0 from 163.
Grab the next digit (9) from the dividend, add it to 163, then carry on: 1639 / 757

Step 4:
When dividing 1639 by 757, we get 2 with a remainder of 125.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 1514 from 1639 to get 125.
Take the next digit (0) from the dividend and append it to 125, then repeat: 1250 / 757

Step 5:
1250 divided by 757 is 1 with a remainder of 493.
The next digit of our result is 1. 
Result so far: 21.0
Deduct 757 from 1250 and we're left with 493.
Append the next digit (6) from the dividend to 493 and continue with: 4936 / 757

Going ahead to step 6:
When dividing 4936 by 757, we get 6 with a remainder of 394.
Write down 6 as next digit of the result. 
Result so far: 216.0
Subtract 4542 from 4936 to get 394.
Take the next digit (4) from the dividend and append it to 394, then repeat: 3944 / 757

Moving on to step 7:
When dividing 3944 by 757, we get 5 with a remainder of 159.
Put 5 as the next digit of the answer. 
Result so far: 2165.0
If we subtract 3785 from 3944, we get 159.
Include the next digit (0) from the dividend after 159, then repeat: 1590 / 757

Let's proceed to step 8:
757 goes into 1590 2 times with a remainder of 76.
The number 2 becomes the next digit in our result. 
Result so far: 21652.0
If we take 1514 away from 1590, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Let's proceed to step 9:
When dividing 760 by 757, we get 1 with a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 21652.1
The remainder is 3 after subtracting 757 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 10:
757 can be fit into 30 0 times, resulting in a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 21652.1
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 11:
757 can be fit into 300 0 times, resulting in a remainder of 300.
Record the quotient 0 as the next digit in the result. 
Result so far: 21652.1
If we subtract 0 from 300, we get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

The final result is 21652.1 with a remainder of 0.03.
