We're dividing 49257457 by 312 
Our goal is to divide 49257457 by 312.

On to step 1:
312 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Grab the next digit (9) from the dividend, add it to 4, then carry on: 49 / 312

On to step 2:
If we divide 49 by 312, we get 0 and a remainder of 49.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 49 to get 49.
Include the next digit (2) from the dividend after 49, then repeat: 492 / 312

Let's proceed to step 3:
The number 312 fits into 492 1 times, leaving a remainder of 180.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 312 from 492, we get 180.
Append the next digit (5) from the dividend to 180 and continue with: 1805 / 312

Advancing to step 4:
When dividing 1805 by 312, we get 5 with a remainder of 245.
The next digit of our result is 5. 
Result so far: 15.0
Subtract 1560 from 1805 to get 245.
Append the next digit (7) from the dividend to 245 and continue with: 2457 / 312

Let's proceed to step 5:
If we divide 2457 by 312, we get 7 and a remainder of 273.
Put 7 as the next digit of the answer. 
Result so far: 157.0
If we subtract 2184 from 2457, we get 273.
Include the next digit (4) from the dividend after 273, then repeat: 2734 / 312

On to step 6:
The number 312 fits into 2734 8 times, leaving a remainder of 238.
Use 8 as the next digit of our solution. 
Result so far: 1578.0
If we take 2496 away from 2734, we end up with 238.
Append the next digit (5) from the dividend to 238 and continue with: 2385 / 312

Moving on to step 7:
312 goes into 2385 7 times with a remainder of 201.
Put 7 as the next digit of the answer. 
Result so far: 15787.0
Subtracting 2184 from 2385 leaves us with 201.
Grab the next digit (7) from the dividend, add it to 201, then carry on: 2017 / 312

Let's proceed to step 8:
312 goes into 2017 6 times with a remainder of 145.
Record the quotient 6 as the next digit in the result. 
Result so far: 157876.0
Subtracting 1872 from 2017 leaves us with 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Going ahead to step 9:
When dividing 1450 by 312, we get 4 with a remainder of 202.
Use 4 as the next digit of our solution. 
Result so far: 157876.4
Deduct 1248 from 1450 and we're left with 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Step 10:
2020 divided by 312 is 6 with a remainder of 148.
Put 6 as the next digit of the answer. 
Result so far: 157876.46
If we take 1872 away from 2020, we end up with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Advancing to step 11:
If we divide 1480 by 312, we get 4 and a remainder of 232.
Write down 4 as next digit of the result. 
Result so far: 157876.464
If we take 1248 away from 1480, 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 12:
If we divide 2320 by 312, we get 7 and a remainder of 136.
Write down 7 as next digit of the result. 
Result so far: 157876.4647
The remainder is 136 after subtracting 2184 from 2320.
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 13:
312 can be fit into 1360 4 times, resulting in a remainder of 112.
The next digit of our result is 4. 
Result so far: 157876.46474
The remainder is 112 after subtracting 1248 from 1360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Step 14:
If we divide 1120 by 312, we get 3 and a remainder of 184.
Use 3 as the next digit of our solution. 
Result so far: 157876.464743
If we subtract 936 from 1120, we get 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Going ahead to step 15:
312 goes into 1840 5 times with a remainder of 280.
The next digit of our result is 5. 
Result so far: 157876.4647435
If we take 1560 away from 1840, we end up 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.

On to step 16:
312 can be fit into 2800 8 times, resulting in a remainder of 304.
The next digit of our result is 8. 
Result so far: 157876.46474358
If we take 2496 away from 2800, we end up with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

The final result is 157876.46474358 with a remainder of 3.04e-07.
