15788196 divided by 402 
Let's see how many times 402 fits into 15788196.

Moving on to step 1:
The number 402 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 402

Advancing to step 2:
The number 402 fits into 15 0 times, leaving a remainder of 15.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 15 after subtracting 0 from 15.
Include the next digit (7) from the dividend after 15, then repeat: 157 / 402

On to step 3:
When dividing 157 by 402, we get 0 with a remainder of 157.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 157 to get 157.
Bring next digit (8) of the dividend behind the 157 and repeat the process: 1578 / 402

Advancing to step 4:
402 goes into 1578 3 times with a remainder of 372.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 1206 from 1578 to get 372.
Include the next digit (8) from the dividend after 372, then repeat: 3728 / 402

Let's proceed to step 5:
402 can be fit into 3728 9 times, resulting in a remainder of 110.
The number 9 becomes the next digit in our result. 
Result so far: 39.0
If we take 3618 away from 3728, we end up with 110.
Append the next digit (1) from the dividend to 110 and continue with: 1101 / 402

Step 6:
If we divide 1101 by 402, we get 2 and a remainder of 297.
Put 2 as the next digit of the answer. 
Result so far: 392.0
Deduct 804 from 1101 and we're left with 297.
Grab the next digit (9) from the dividend, add it to 297, then carry on: 2979 / 402

Step 7:
If we divide 2979 by 402, we get 7 and a remainder of 165.
The number 7 becomes the next digit in our result. 
Result so far: 3927.0
If we take 2814 away from 2979, we end up with 165.
Grab the next digit (6) from the dividend, add it to 165, then carry on: 1656 / 402

Let's proceed to step 8:
The number 402 fits into 1656 4 times, leaving a remainder of 48.
The next digit of our result is 4. 
Result so far: 39274.0
Subtracting 1608 from 1656 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 9:
402 can be fit into 480 1 times, resulting in a remainder of 78.
Use 1 as the next digit of our solution. 
Result so far: 39274.1
Subtracting 402 from 480 leaves us with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Going ahead to step 10:
If we divide 780 by 402, we get 1 and a remainder of 378.
Write down 1 as next digit of the result. 
Result so far: 39274.11
Deduct 402 from 780 and we're left with 378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

Our division results in 39274.11 with a remaining 0.378.
