We look at the division of 15914128 by 766 
We're looking to find how many times 766 goes into 15914128.

Going ahead to step 1:
1 divided by 766 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 766

Advancing to step 2:
When dividing 15 by 766, we get 0 with a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Fetch the next digit (9) from the dividend, attach it to 15 and continue: 159 / 766

Let's proceed to step 3:
When dividing 159 by 766, we get 0 with a remainder of 159.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 159 leaves us with 159.
Fetch the next digit (1) from the dividend, attach it to 159 and continue: 1591 / 766

Advancing to step 4:
When dividing 1591 by 766, we get 2 with a remainder of 59.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 1532 away from 1591, we end up with 59.
Bring next digit (4) of the dividend behind the 59 and repeat the process: 594 / 766

Advancing to step 5:
If we divide 594 by 766, we get 0 and a remainder of 594.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
Deduct 0 from 594 and we're left with 594.
Append the next digit (1) from the dividend to 594 and continue with: 5941 / 766

Going ahead to step 6:
The number 766 fits into 5941 7 times, leaving a remainder of 579.
Record the quotient 7 as the next digit in the result. 
Result so far: 207.0
If we take 5362 away from 5941, we end up with 579.
Append the next digit (2) from the dividend to 579 and continue with: 5792 / 766

On to step 7:
If we divide 5792 by 766, we get 7 and a remainder of 430.
Put 7 as the next digit of the answer. 
Result so far: 2077.0
If we subtract 5362 from 5792, we get 430.
Fetch the next digit (8) from the dividend, attach it to 430 and continue: 4308 / 766

Advancing to step 8:
766 goes into 4308 5 times with a remainder of 478.
Put 5 as the next digit of the answer. 
Result so far: 20775.0
Deduct 3830 from 4308 and we're left with 478.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4780, and continue the process.

Step 9:
When dividing 4780 by 766, we get 6 with a remainder of 184.
Put 6 as the next digit of the answer. 
Result so far: 20775.6
If we subtract 4596 from 4780, we get 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

On to step 10:
If we divide 1840 by 766, we get 2 and a remainder of 308.
The number 2 becomes the next digit in our result. 
Result so far: 20775.62
Deduct 1532 from 1840 and we're left with 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

On to step 11:
766 goes into 3080 4 times with a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 20775.624
The remainder is 16 after subtracting 3064 from 3080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 12:
766 goes into 160 0 times with a remainder of 160.
The next digit of our result is 0. 
Result so far: 20775.624
The remainder is 160 after subtracting 0 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Going ahead to step 13:
The number 766 fits into 1600 2 times, leaving a remainder of 68.
Use 2 as the next digit of our solution. 
Result so far: 20775.62402
Subtract 1532 from 1600 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 14:
766 goes into 680 0 times with a remainder of 680.
The number 0 becomes the next digit in our result. 
Result so far: 20775.62402
If we take 0 away from 680, we end up with 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

Step 15:
766 goes into 6800 8 times with a remainder of 672.
The number 8 becomes the next digit in our result. 
Result so far: 20775.6240208
If we take 6128 away from 6800, we end up with 672.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6720, and continue the process.

On to step 16:
The number 766 fits into 6720 8 times, leaving a remainder of 592.
The number 8 becomes the next digit in our result. 
Result so far: 20775.62402088
Subtracting 6128 from 6720 leaves us with 592.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5920, and continue the process.

The final outcome is 20775.62402088, with a leftover of 5.92e-07.
