We divide 315189 by 23
We want to divide 315189 by 23.

Going ahead to step 1:
The number 23 fits into 3 0 times, leaving a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 23

Advancing to step 2:
23 goes into 31 1 times with a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 23 away from 31, we end up with 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 23

Advancing to step 3:
The number 23 fits into 85 3 times, leaving a remainder of 16.
Use 3 as the next digit of our solution. 
Result so far: 13.0
If we take 69 away from 85, we end up with 16.
Include the next digit (1) from the dividend after 16, then repeat: 161 / 23

Going ahead to step 4:
23 goes into 161 7 times with a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 137.0
If we take 161 away from 161, we end up with 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 23

Advancing to step 5:
23 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 1370.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (9) from the dividend after 8, then repeat: 89 / 23

Going ahead to step 6:
The number 23 fits into 89 3 times, leaving a remainder of 20.
Put 3 as the next digit of the answer. 
Result so far: 13703.0
The remainder is 20 after subtracting 69 from 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 7:
23 can be fit into 200 8 times, resulting in a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 13703.8
If we subtract 184 from 200, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 8:
The number 23 fits into 160 6 times, leaving a remainder of 22.
Write down 6 as next digit of the result. 
Result so far: 13703.86
The remainder is 22 after subtracting 138 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 9:
220 divided by 23 is 9 with a remainder of 13.
Use 9 as the next digit of our solution. 
Result so far: 13703.869
Subtract 207 from 220 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 10:
The number 23 fits into 130 5 times, leaving a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 13703.8695
The remainder is 15 after subtracting 115 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 11:
When dividing 150 by 23, we get 6 with a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 13703.86956
The remainder is 12 after subtracting 138 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 12:
23 can be fit into 120 5 times, resulting in a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 13703.869565
The remainder is 5 after subtracting 115 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 13:
When dividing 50 by 23, we get 2 with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 13703.8695652
If we take 46 away from 50, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 14:
23 can be fit into 40 1 times, resulting in a remainder of 17.
Use 1 as the next digit of our solution. 
Result so far: 13703.86956521
If we subtract 23 from 40, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

The quotient of the division is 13703.86956521, and the remainder is 1.7e-08.
