Let's divide 15862978 by 756
We're looking to find how many times 756 goes into 15862978.

Let's proceed to step 1:
756 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 756

Step 2:
If we divide 15 by 756, we get 0 and a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 15, we get 15.
Fetch the next digit (8) from the dividend, attach it to 15 and continue: 158 / 756

Let's proceed to step 3:
When dividing 158 by 756, we get 0 with a remainder of 158.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 158 after subtracting 0 from 158.
Take the next digit (6) from the dividend and append it to 158, then repeat: 1586 / 756

Moving on to step 4:
If we divide 1586 by 756, we get 2 and a remainder of 74.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 1512 from 1586 and we're left with 74.
Bring next digit (2) of the dividend behind the 74 and repeat the process: 742 / 756

Let's proceed to step 5:
742 divided by 756 is 0 with a remainder of 742.
Write down 0 as next digit of the result. 
Result so far: 20.0
If we take 0 away from 742, we end up with 742.
Append the next digit (9) from the dividend to 742 and continue with: 7429 / 756

Advancing to step 6:
If we divide 7429 by 756, we get 9 and a remainder of 625.
Put 9 as the next digit of the answer. 
Result so far: 209.0
The remainder is 625 after subtracting 6804 from 7429.
Append the next digit (7) from the dividend to 625 and continue with: 6257 / 756

Advancing to step 7:
The number 756 fits into 6257 8 times, leaving a remainder of 209.
Put 8 as the next digit of the answer. 
Result so far: 2098.0
Deduct 6048 from 6257 and we're left with 209.
Take the next digit (8) from the dividend and append it to 209, then repeat: 2098 / 756

Advancing to step 8:
The number 756 fits into 2098 2 times, leaving a remainder of 586.
The number 2 becomes the next digit in our result. 
Result so far: 20982.0
Subtract 1512 from 2098 to get 586.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5860, and continue the process.

Going ahead to step 9:
5860 divided by 756 is 7 with a remainder of 568.
Record the quotient 7 as the next digit in the result. 
Result so far: 20982.7
Subtract 5292 from 5860 to get 568.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5680, and continue the process.

Step 10:
When dividing 5680 by 756, we get 7 with a remainder of 388.
The next digit of our result is 7. 
Result so far: 20982.77
Deduct 5292 from 5680 and we're left with 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

The final result is 20982.77 with a remainder of 0.388.
