Let's divide 15486424 by 312
We're looking to find how many times 312 goes into 15486424.

Going ahead to step 1:
If we divide 1 by 312, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 312

Let's proceed to step 2:
312 goes into 15 0 times with a remainder of 15.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 15 leaves us with 15.
Grab the next digit (4) from the dividend, add it to 15, then carry on: 154 / 312

On to step 3:
If we divide 154 by 312, we get 0 and a remainder of 154.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 154 and we're left with 154.
Fetch the next digit (8) from the dividend, attach it to 154 and continue: 1548 / 312

On to step 4:
312 goes into 1548 4 times with a remainder of 300.
The next digit of our result is 4. 
Result so far: 4.0
The remainder is 300 after subtracting 1248 from 1548.
Grab the next digit (6) from the dividend, add it to 300, then carry on: 3006 / 312

Let's proceed to step 5:
312 goes into 3006 9 times with a remainder of 198.
The next digit of our result is 9. 
Result so far: 49.0
Subtracting 2808 from 3006 leaves us with 198.
Include the next digit (4) from the dividend after 198, then repeat: 1984 / 312

Let's proceed to step 6:
312 goes into 1984 6 times with a remainder of 112.
Put 6 as the next digit of the answer. 
Result so far: 496.0
Subtract 1872 from 1984 to get 112.
Fetch the next digit (2) from the dividend, attach it to 112 and continue: 1122 / 312

Advancing to step 7:
1122 divided by 312 is 3 with a remainder of 186.
Put 3 as the next digit of the answer. 
Result so far: 4963.0
Subtracting 936 from 1122 leaves us with 186.
Take the next digit (4) from the dividend and append it to 186, then repeat: 1864 / 312

Let's proceed to step 8:
312 can be fit into 1864 5 times, resulting in a remainder of 304.
Put 5 as the next digit of the answer. 
Result so far: 49635.0
If we subtract 1560 from 1864, we get 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Going ahead to step 9:
3040 divided by 312 is 9 with a remainder of 232.
The next digit of our result is 9. 
Result so far: 49635.9
If we take 2808 away from 3040, we end up with 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Moving on to step 10:
312 can be fit into 2320 7 times, resulting in a remainder of 136.
Record the quotient 7 as the next digit in the result. 
Result so far: 49635.97
If we subtract 2184 from 2320, we get 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Moving on to step 11:
312 can be fit into 1360 4 times, resulting in a remainder of 112.
Record the quotient 4 as the next digit in the result. 
Result so far: 49635.974
Deduct 1248 from 1360 and we're left with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Let's proceed to step 12:
312 goes into 1120 3 times with a remainder of 184.
Write down 3 as next digit of the result. 
Result so far: 49635.9743
If we take 936 away from 1120, we end up with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Step 13:
312 can be fit into 1840 5 times, resulting in a remainder of 280.
Put 5 as the next digit of the answer. 
Result so far: 49635.97435
Deduct 1560 from 1840 and we're left with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Going ahead to step 14:
The number 312 fits into 2800 8 times, leaving a remainder of 304.
Record the quotient 8 as the next digit in the result. 
Result so far: 49635.974358
Subtract 2496 from 2800 to get 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

On to step 15:
3040 divided by 312 is 9 with a remainder of 232.
Record the quotient 9 as the next digit in the result. 
Result so far: 49635.9743589
The remainder is 232 after subtracting 2808 from 3040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Let's proceed to step 16:
When dividing 2320 by 312, we get 7 with a remainder of 136.
Use 7 as the next digit of our solution. 
Result so far: 49635.97435897
If we subtract 2184 from 2320, we get 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

The final result is 49635.97435897 with a remainder of 1.36e-07.
