Let's divide 15322128 by 780
We want to divide 15322128 by 780.

Step 1:
780 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 780

Let's proceed to step 2:
780 can be fit into 15 0 times, resulting in a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Include the next digit (3) from the dividend after 15, then repeat: 153 / 780

Advancing to step 3:
If we divide 153 by 780, we get 0 and a remainder of 153.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 153, we end up with 153.
Fetch the next digit (2) from the dividend, attach it to 153 and continue: 1532 / 780

Let's proceed to step 4:
1532 divided by 780 is 1 with a remainder of 752.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 752 after subtracting 780 from 1532.
Fetch the next digit (2) from the dividend, attach it to 752 and continue: 7522 / 780

Step 5:
7522 divided by 780 is 9 with a remainder of 502.
Use 9 as the next digit of our solution. 
Result so far: 19.0
If we take 7020 away from 7522, we end up with 502.
Include the next digit (1) from the dividend after 502, then repeat: 5021 / 780

Let's proceed to step 6:
The number 780 fits into 5021 6 times, leaving a remainder of 341.
Record the quotient 6 as the next digit in the result. 
Result so far: 196.0
Subtracting 4680 from 5021 leaves us with 341.
Grab the next digit (2) from the dividend, add it to 341, then carry on: 3412 / 780

Advancing to step 7:
780 can be fit into 3412 4 times, resulting in a remainder of 292.
Record the quotient 4 as the next digit in the result. 
Result so far: 1964.0
Subtract 3120 from 3412 to get 292.
Fetch the next digit (8) from the dividend, attach it to 292 and continue: 2928 / 780

Advancing to step 8:
2928 divided by 780 is 3 with a remainder of 588.
Write down 3 as next digit of the result. 
Result so far: 19643.0
The remainder is 588 after subtracting 2340 from 2928.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5880, and continue the process.

Moving on to step 9:
5880 divided by 780 is 7 with a remainder of 420.
The number 7 becomes the next digit in our result. 
Result so far: 19643.7
Subtract 5460 from 5880 to get 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Let's proceed to step 10:
When dividing 4200 by 780, we get 5 with a remainder of 300.
Record the quotient 5 as the next digit in the result. 
Result so far: 19643.75
Deduct 3900 from 4200 and we're left with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Advancing to step 11:
3000 divided by 780 is 3 with a remainder of 660.
Put 3 as the next digit of the answer. 
Result so far: 19643.753
If we subtract 2340 from 3000, we get 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

Let's proceed to step 12:
The number 780 fits into 6600 8 times, leaving a remainder of 360.
The next digit of our result is 8. 
Result so far: 19643.7538
Subtracting 6240 from 6600 leaves us with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Step 13:
The number 780 fits into 3600 4 times, leaving a remainder of 480.
Record the quotient 4 as the next digit in the result. 
Result so far: 19643.75384
Subtracting 3120 from 3600 leaves us with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Step 14:
780 goes into 4800 6 times with a remainder of 120.
Write down 6 as next digit of the result. 
Result so far: 19643.753846
If we subtract 4680 from 4800, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Going ahead to step 15:
780 can be fit into 1200 1 times, resulting in a remainder of 420.
Put 1 as the next digit of the answer. 
Result so far: 19643.7538461
Deduct 780 from 1200 and we're left with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Let's proceed to step 16:
4200 divided by 780 is 5 with a remainder of 300.
Write down 5 as next digit of the result. 
Result so far: 19643.75384615
The remainder is 300 after subtracting 3900 from 4200.
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 outcome is 19643.75384615, with a leftover of 3e-07.
