We divide 15578610 by 312
We want to divide 15578610 by 312.

Advancing to step 1:
When dividing 1 by 312, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 312

Moving on to step 2:
When dividing 15 by 312, we get 0 with a remainder of 15.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 15 after subtracting 0 from 15.
Take the next digit (5) from the dividend and append it to 15, then repeat: 155 / 312

Advancing to step 3:
155 divided by 312 is 0 with a remainder of 155.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 155 leaves us with 155.
Take the next digit (7) from the dividend and append it to 155, then repeat: 1557 / 312

Advancing to step 4:
When dividing 1557 by 312, we get 4 with a remainder of 309.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Deduct 1248 from 1557 and we're left with 309.
Grab the next digit (8) from the dividend, add it to 309, then carry on: 3098 / 312

Advancing to step 5:
312 can be fit into 3098 9 times, resulting in a remainder of 290.
Write down 9 as next digit of the result. 
Result so far: 49.0
The remainder is 290 after subtracting 2808 from 3098.
Grab the next digit (6) from the dividend, add it to 290, then carry on: 2906 / 312

Step 6:
The number 312 fits into 2906 9 times, leaving a remainder of 98.
Record the quotient 9 as the next digit in the result. 
Result so far: 499.0
The remainder is 98 after subtracting 2808 from 2906.
Fetch the next digit (1) from the dividend, attach it to 98 and continue: 981 / 312

Let's proceed to step 7:
312 goes into 981 3 times with a remainder of 45.
Put 3 as the next digit of the answer. 
Result so far: 4993.0
Subtract 936 from 981 to get 45.
Bring next digit (0) of the dividend behind the 45 and repeat the process: 450 / 312

Moving on to step 8:
312 goes into 450 1 times with a remainder of 138.
Write down 1 as next digit of the result. 
Result so far: 49931.0
Subtract 312 from 450 to get 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Going ahead to step 9:
The number 312 fits into 1380 4 times, leaving a remainder of 132.
The next digit of our result is 4. 
Result so far: 49931.4
Subtract 1248 from 1380 to get 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Moving on to step 10:
312 can be fit into 1320 4 times, resulting in a remainder of 72.
Put 4 as the next digit of the answer. 
Result so far: 49931.44
If we take 1248 away from 1320, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

The quotient of the division is 49931.44, and the remainder is 0.072.
