We're dividing 15315278 by 754 
Let's see how many times 754 fits into 15315278.

Advancing to step 1:
754 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 754

Moving on to step 2:
When dividing 15 by 754, we get 0 with a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 15 to get 15.
Append the next digit (3) from the dividend to 15 and continue with: 153 / 754

Moving on to step 3:
If we divide 153 by 754, we get 0 and a remainder of 153.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 153, we end up with 153.
Include the next digit (1) from the dividend after 153, then repeat: 1531 / 754

Going ahead to step 4:
If we divide 1531 by 754, we get 2 and a remainder of 23.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 1508 from 1531 leaves us with 23.
Bring next digit (5) of the dividend behind the 23 and repeat the process: 235 / 754

Going ahead to step 5:
754 goes into 235 0 times with a remainder of 235.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
The remainder is 235 after subtracting 0 from 235.
Include the next digit (2) from the dividend after 235, then repeat: 2352 / 754

Going ahead to step 6:
2352 divided by 754 is 3 with a remainder of 90.
Record the quotient 3 as the next digit in the result. 
Result so far: 203.0
Subtract 2262 from 2352 to get 90.
Grab the next digit (7) from the dividend, add it to 90, then carry on: 907 / 754

Moving on to step 7:
The number 754 fits into 907 1 times, leaving a remainder of 153.
The number 1 becomes the next digit in our result. 
Result so far: 2031.0
Deduct 754 from 907 and we're left with 153.
Grab the next digit (8) from the dividend, add it to 153, then carry on: 1538 / 754

Going ahead to step 8:
1538 divided by 754 is 2 with a remainder of 30.
The number 2 becomes the next digit in our result. 
Result so far: 20312.0
If we take 1508 away from 1538, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 9:
The number 754 fits into 300 0 times, leaving a remainder of 300.
Record the quotient 0 as the next digit in the result. 
Result so far: 20312.0
If we take 0 away from 300, we end up 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.

Let's proceed to step 10:
When dividing 3000 by 754, we get 3 with a remainder of 738.
Record the quotient 3 as the next digit in the result. 
Result so far: 20312.03
The remainder is 738 after subtracting 2262 from 3000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7380, and continue the process.

On to step 11:
If we divide 7380 by 754, we get 9 and a remainder of 594.
Put 9 as the next digit of the answer. 
Result so far: 20312.039
If we take 6786 away from 7380, we end up with 594.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5940, and continue the process.

Let's proceed to step 12:
754 can be fit into 5940 7 times, resulting in a remainder of 662.
Put 7 as the next digit of the answer. 
Result so far: 20312.0397
The remainder is 662 after subtracting 5278 from 5940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6620, and continue the process.

Step 13:
754 can be fit into 6620 8 times, resulting in a remainder of 588.
The next digit of our result is 8. 
Result so far: 20312.03978
The remainder is 588 after subtracting 6032 from 6620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5880, and continue the process.

Step 14:
754 goes into 5880 7 times with a remainder of 602.
The number 7 becomes the next digit in our result. 
Result so far: 20312.039787
The remainder is 602 after subtracting 5278 from 5880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6020, and continue the process.

Step 15:
6020 divided by 754 is 7 with a remainder of 742.
Put 7 as the next digit of the answer. 
Result so far: 20312.0397877
If we take 5278 away from 6020, we end up with 742.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7420, and continue the process.

After the division, we end up with 20312.0397877 and a remainder of 7.42e-06.
