We look at the division of 11999233 by 780 
We want to figure out the number of times 11999233 can be divided by 780.

On to step 1:
When dividing 1 by 780, we get 0 with 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.
Bring next digit (1) of the dividend behind the 1 and repeat the process: 11 / 780

Going ahead to step 2:
780 can be fit into 11 0 times, resulting in a remainder of 11.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 11, we get 11.
Take the next digit (9) from the dividend and append it to 11, then repeat: 119 / 780

On to step 3:
If we divide 119 by 780, we get 0 and a remainder of 119.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 119, we get 119.
Bring next digit (9) of the dividend behind the 119 and repeat the process: 1199 / 780

Step 4:
780 goes into 1199 1 times with a remainder of 419.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 780 from 1199 to get 419.
Bring next digit (9) of the dividend behind the 419 and repeat the process: 4199 / 780

Let's proceed to step 5:
780 goes into 4199 5 times with a remainder of 299.
Write down 5 as next digit of the result. 
Result so far: 15.0
If we take 3900 away from 4199, we end up with 299.
Grab the next digit (2) from the dividend, add it to 299, then carry on: 2992 / 780

Let's proceed to step 6:
780 goes into 2992 3 times with a remainder of 652.
Record the quotient 3 as the next digit in the result. 
Result so far: 153.0
Subtracting 2340 from 2992 leaves us with 652.
Take the next digit (3) from the dividend and append it to 652, then repeat: 6523 / 780

On to step 7:
When dividing 6523 by 780, we get 8 with a remainder of 283.
The number 8 becomes the next digit in our result. 
Result so far: 1538.0
If we take 6240 away from 6523, we end up with 283.
Take the next digit (3) from the dividend and append it to 283, then repeat: 2833 / 780

Let's proceed to step 8:
780 goes into 2833 3 times with a remainder of 493.
Use 3 as the next digit of our solution. 
Result so far: 15383.0
The remainder is 493 after subtracting 2340 from 2833.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4930, and continue the process.

Advancing to step 9:
4930 divided by 780 is 6 with a remainder of 250.
Write down 6 as next digit of the result. 
Result so far: 15383.6
Subtracting 4680 from 4930 leaves us with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Let's proceed to step 10:
780 can be fit into 2500 3 times, resulting in a remainder of 160.
Write down 3 as next digit of the result. 
Result so far: 15383.63
If we take 2340 away from 2500, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Step 11:
1600 divided by 780 is 2 with a remainder of 40.
Record the quotient 2 as the next digit in the result. 
Result so far: 15383.632
Deduct 1560 from 1600 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 12:
When dividing 400 by 780, we get 0 with a remainder of 400.
Write down 0 as next digit of the result. 
Result so far: 15383.632
Subtract 0 from 400 to get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Moving on to step 13:
780 can be fit into 4000 5 times, resulting in a remainder of 100.
Use 5 as the next digit of our solution. 
Result so far: 15383.63205
The remainder is 100 after subtracting 3900 from 4000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Step 14:
When dividing 1000 by 780, we get 1 with a remainder of 220.
Write down 1 as next digit of the result. 
Result so far: 15383.632051
Subtract 780 from 1000 to get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Advancing to step 15:
If we divide 2200 by 780, we get 2 and a remainder of 640.
Write down 2 as next digit of the result. 
Result so far: 15383.6320512
Subtracting 1560 from 2200 leaves us with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Advancing to step 16:
When dividing 6400 by 780, we get 8 with a remainder of 160.
Write down 8 as next digit of the result. 
Result so far: 15383.63205128
The remainder is 160 after subtracting 6240 from 6400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

The final outcome is 15383.63205128, with a leftover of 1.6e-07.
