13990148 divided by 765 
We want to figure out the number of times 13990148 can be divided by 765.

Advancing to step 1:
765 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 765

Let's proceed to step 2:
If we divide 13 by 765, we get 0 and a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 13 and we're left with 13.
Bring next digit (9) of the dividend behind the 13 and repeat the process: 139 / 765

On to step 3:
765 can be fit into 139 0 times, resulting in a remainder of 139.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 139, we get 139.
Take the next digit (9) from the dividend and append it to 139, then repeat: 1399 / 765

Advancing to step 4:
1399 divided by 765 is 1 with a remainder of 634.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 765 from 1399 and we're left with 634.
Grab the next digit (0) from the dividend, add it to 634, then carry on: 6340 / 765

Step 5:
The number 765 fits into 6340 8 times, leaving a remainder of 220.
Put 8 as the next digit of the answer. 
Result so far: 18.0
Subtracting 6120 from 6340 leaves us with 220.
Append the next digit (1) from the dividend to 220 and continue with: 2201 / 765

Moving on to step 6:
If we divide 2201 by 765, we get 2 and a remainder of 671.
The number 2 becomes the next digit in our result. 
Result so far: 182.0
The remainder is 671 after subtracting 1530 from 2201.
Grab the next digit (4) from the dividend, add it to 671, then carry on: 6714 / 765

Let's proceed to step 7:
6714 divided by 765 is 8 with a remainder of 594.
Use 8 as the next digit of our solution. 
Result so far: 1828.0
If we subtract 6120 from 6714, we get 594.
Grab the next digit (8) from the dividend, add it to 594, then carry on: 5948 / 765

Advancing to step 8:
If we divide 5948 by 765, we get 7 and a remainder of 593.
Write down 7 as next digit of the result. 
Result so far: 18287.0
Subtract 5355 from 5948 to get 593.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5930, and continue the process.

Step 9:
When dividing 5930 by 765, we get 7 with a remainder of 575.
Put 7 as the next digit of the answer. 
Result so far: 18287.7
Subtracting 5355 from 5930 leaves us with 575.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5750, and continue the process.

Let's proceed to step 10:
765 can be fit into 5750 7 times, resulting in a remainder of 395.
Record the quotient 7 as the next digit in the result. 
Result so far: 18287.77
If we subtract 5355 from 5750, we get 395.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3950, and continue the process.

Our division results in 18287.77 with a remaining 0.395.
