Let's divide 43758487 by 315
Our goal is to divide 43758487 by 315.

Step 1:
4 divided by 315 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 315

Moving on to step 2:
If we divide 43 by 315, we get 0 and a remainder of 43.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 43 to get 43.
Append the next digit (7) from the dividend to 43 and continue with: 437 / 315

Going ahead to step 3:
The number 315 fits into 437 1 times, leaving a remainder of 122.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 315 from 437, we get 122.
Include the next digit (5) from the dividend after 122, then repeat: 1225 / 315

Advancing to step 4:
The number 315 fits into 1225 3 times, leaving a remainder of 280.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
If we take 945 away from 1225, we end up with 280.
Append the next digit (8) from the dividend to 280 and continue with: 2808 / 315

Moving on to step 5:
315 can be fit into 2808 8 times, resulting in a remainder of 288.
The number 8 becomes the next digit in our result. 
Result so far: 138.0
If we take 2520 away from 2808, we end up with 288.
Fetch the next digit (4) from the dividend, attach it to 288 and continue: 2884 / 315

Step 6:
When dividing 2884 by 315, we get 9 with a remainder of 49.
Write down 9 as next digit of the result. 
Result so far: 1389.0
The remainder is 49 after subtracting 2835 from 2884.
Include the next digit (8) from the dividend after 49, then repeat: 498 / 315

Step 7:
315 can be fit into 498 1 times, resulting in a remainder of 183.
Use 1 as the next digit of our solution. 
Result so far: 13891.0
Subtracting 315 from 498 leaves us with 183.
Fetch the next digit (7) from the dividend, attach it to 183 and continue: 1837 / 315

On to step 8:
When dividing 1837 by 315, we get 5 with a remainder of 262.
Use 5 as the next digit of our solution. 
Result so far: 138915.0
Subtracting 1575 from 1837 leaves us with 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

Let's proceed to step 9:
2620 divided by 315 is 8 with a remainder of 100.
Put 8 as the next digit of the answer. 
Result so far: 138915.8
If we take 2520 away from 2620, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Moving on to step 10:
The number 315 fits into 1000 3 times, leaving a remainder of 55.
Use 3 as the next digit of our solution. 
Result so far: 138915.83
Deduct 945 from 1000 and we're left with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Step 11:
550 divided by 315 is 1 with a remainder of 235.
The next digit of our result is 1. 
Result so far: 138915.831
Deduct 315 from 550 and we're left with 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

Let's proceed to step 12:
When dividing 2350 by 315, we get 7 with a remainder of 145.
Write down 7 as next digit of the result. 
Result so far: 138915.8317
The remainder is 145 after subtracting 2205 from 2350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Step 13:
315 goes into 1450 4 times with a remainder of 190.
The next digit of our result is 4. 
Result so far: 138915.83174
Subtracting 1260 from 1450 leaves us with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Step 14:
The number 315 fits into 1900 6 times, leaving a remainder of 10.
The number 6 becomes the next digit in our result. 
Result so far: 138915.831746
Subtract 1890 from 1900 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 15:
100 divided by 315 is 0 with a remainder of 100.
Put 0 as the next digit of the answer. 
Result so far: 138915.831746
Deduct 0 from 100 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Going ahead to step 16:
1000 divided by 315 is 3 with a remainder of 55.
Use 3 as the next digit of our solution. 
Result so far: 138915.83174603
If we subtract 945 from 1000, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Our division results in 138915.83174603 with a remaining 5.5e-08.
