Let's divide 16139754 by 757
We're looking to find how many times 757 goes into 16139754.

Advancing to step 1:
757 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 757

Step 2:
757 can be fit into 16 0 times, resulting in a remainder of 16.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 16 after subtracting 0 from 16.
Fetch the next digit (1) from the dividend, attach it to 16 and continue: 161 / 757

Moving on to step 3:
If we divide 161 by 757, we get 0 and a remainder of 161.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 161 and we're left with 161.
Fetch the next digit (3) from the dividend, attach it to 161 and continue: 1613 / 757

Going ahead to step 4:
The number 757 fits into 1613 2 times, leaving a remainder of 99.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 1514 from 1613 leaves us with 99.
Bring next digit (9) of the dividend behind the 99 and repeat the process: 999 / 757

Going ahead to step 5:
757 goes into 999 1 times with a remainder of 242.
The next digit of our result is 1. 
Result so far: 21.0
Deduct 757 from 999 and we're left with 242.
Append the next digit (7) from the dividend to 242 and continue with: 2427 / 757

Advancing to step 6:
The number 757 fits into 2427 3 times, leaving a remainder of 156.
Use 3 as the next digit of our solution. 
Result so far: 213.0
Subtracting 2271 from 2427 leaves us with 156.
Include the next digit (5) from the dividend after 156, then repeat: 1565 / 757

Moving on to step 7:
The number 757 fits into 1565 2 times, leaving a remainder of 51.
The next digit of our result is 2. 
Result so far: 2132.0
Deduct 1514 from 1565 and we're left with 51.
Grab the next digit (4) from the dividend, add it to 51, then carry on: 514 / 757

On to step 8:
The number 757 fits into 514 0 times, leaving a remainder of 514.
Put 0 as the next digit of the answer. 
Result so far: 21320.0
Subtract 0 from 514 to get 514.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5140, and continue the process.

Advancing to step 9:
When dividing 5140 by 757, we get 6 with a remainder of 598.
Write down 6 as next digit of the result. 
Result so far: 21320.6
If we subtract 4542 from 5140, we get 598.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5980, and continue the process.

Moving on to step 10:
When dividing 5980 by 757, we get 7 with a remainder of 681.
The number 7 becomes the next digit in our result. 
Result so far: 21320.67
If we subtract 5299 from 5980, we get 681.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6810, and continue the process.

Let's proceed to step 11:
The number 757 fits into 6810 8 times, leaving a remainder of 754.
The next digit of our result is 8. 
Result so far: 21320.678
The remainder is 754 after subtracting 6056 from 6810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7540, and continue the process.

On to step 12:
757 can be fit into 7540 9 times, resulting in a remainder of 727.
The next digit of our result is 9. 
Result so far: 21320.6789
If we subtract 6813 from 7540, we get 727.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7270, and continue the process.

Advancing to step 13:
The number 757 fits into 7270 9 times, leaving a remainder of 457.
The number 9 becomes the next digit in our result. 
Result so far: 21320.67899
The remainder is 457 after subtracting 6813 from 7270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4570, and continue the process.

The final outcome is 21320.67899, with a leftover of 0.000457.
