We look at the division of 315690 by 43 
We're looking to find how many times 43 goes into 315690.

Advancing to step 1:
3 divided by 43 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 43

Let's proceed to step 2:
When dividing 31 by 43, we get 0 with a remainder of 31.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 31 to get 31.
Grab the next digit (5) from the dividend, add it to 31, then carry on: 315 / 43

Let's proceed to step 3:
The number 43 fits into 315 7 times, leaving a remainder of 14.
The next digit of our result is 7. 
Result so far: 7.0
Subtract 301 from 315 to get 14.
Include the next digit (6) from the dividend after 14, then repeat: 146 / 43

Let's proceed to step 4:
When dividing 146 by 43, we get 3 with a remainder of 17.
The next digit of our result is 3. 
Result so far: 73.0
If we take 129 away from 146, we end up with 17.
Fetch the next digit (9) from the dividend, attach it to 17 and continue: 179 / 43

Let's proceed to step 5:
If we divide 179 by 43, we get 4 and a remainder of 7.
Use 4 as the next digit of our solution. 
Result so far: 734.0
If we subtract 172 from 179, we get 7.
Include the next digit (0) from the dividend after 7, then repeat: 70 / 43

Let's proceed to step 6:
70 divided by 43 is 1 with a remainder of 27.
The next digit of our result is 1. 
Result so far: 7341.0
If we subtract 43 from 70, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 7:
When dividing 270 by 43, we get 6 with a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 7341.6
If we take 258 away from 270, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 8:
The number 43 fits into 120 2 times, leaving a remainder of 34.
Record the quotient 2 as the next digit in the result. 
Result so far: 7341.62
The remainder is 34 after subtracting 86 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 9:
When dividing 340 by 43, we get 7 with a remainder of 39.
Put 7 as the next digit of the answer. 
Result so far: 7341.627
Subtracting 301 from 340 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 10:
390 divided by 43 is 9 with a remainder of 3.
The next digit of our result is 9. 
Result so far: 7341.6279
If we take 387 away from 390, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 11:
43 can be fit into 30 0 times, resulting in a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 7341.6279
Subtracting 0 from 30 leaves us 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.

Moving on to step 12:
When dividing 300 by 43, we get 6 with a remainder of 42.
Use 6 as the next digit of our solution. 
Result so far: 7341.627906
Deduct 258 from 300 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 13:
43 can be fit into 420 9 times, resulting in a remainder of 33.
Put 9 as the next digit of the answer. 
Result so far: 7341.6279069
If we take 387 away from 420, we end up with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Moving on to step 14:
If we divide 330 by 43, we get 7 and a remainder of 29.
Put 7 as the next digit of the answer. 
Result so far: 7341.62790697
Deduct 301 from 330 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Our division results in 7341.62790697 with a remaining 2.9e-08.
