We look at the division of 123157 by 87 
We're looking to find how many times 87 goes into 123157.

Advancing to step 1:
87 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 87

Step 2:
When dividing 12 by 87, we get 0 with a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Fetch the next digit (3) from the dividend, attach it to 12 and continue: 123 / 87

Step 3:
123 divided by 87 is 1 with a remainder of 36.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 87 from 123 to get 36.
Append the next digit (1) from the dividend to 36 and continue with: 361 / 87

Going ahead to step 4:
If we divide 361 by 87, we get 4 and a remainder of 13.
Use 4 as the next digit of our solution. 
Result so far: 14.0
Subtracting 348 from 361 leaves us with 13.
Include the next digit (5) from the dividend after 13, then repeat: 135 / 87

Going ahead to step 5:
The number 87 fits into 135 1 times, leaving a remainder of 48.
The number 1 becomes the next digit in our result. 
Result so far: 141.0
The remainder is 48 after subtracting 87 from 135.
Grab the next digit (7) from the dividend, add it to 48, then carry on: 487 / 87

Moving on to step 6:
The number 87 fits into 487 5 times, leaving a remainder of 52.
Use 5 as the next digit of our solution. 
Result so far: 1415.0
Subtracting 435 from 487 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 7:
520 divided by 87 is 5 with a remainder of 85.
The next digit of our result is 5. 
Result so far: 1415.5
If we take 435 away from 520, we end up with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Going ahead to step 8:
If we divide 850 by 87, we get 9 and a remainder of 67.
The next digit of our result is 9. 
Result so far: 1415.59
Subtracting 783 from 850 leaves us with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Going ahead to step 9:
670 divided by 87 is 7 with a remainder of 61.
Record the quotient 7 as the next digit in the result. 
Result so far: 1415.597
Subtract 609 from 670 to get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

On to step 10:
If we divide 610 by 87, we get 7 and a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 1415.5977
If we take 609 away from 610, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

In conclusion, the division gives 1415.5977 with a balance of 1e-05.
