We're dividing 123400 by 86 
We're looking to find how many times 86 goes into 123400.

On to step 1:
1 divided by 86 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 86

Let's proceed to step 2:
The number 86 fits into 12 0 times, leaving a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Include the next digit (3) from the dividend after 12, then repeat: 123 / 86

Advancing to step 3:
86 goes into 123 1 times with a remainder of 37.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 86 from 123 leaves us with 37.
Append the next digit (4) from the dividend to 37 and continue with: 374 / 86

On to step 4:
374 divided by 86 is 4 with a remainder of 30.
Write down 4 as next digit of the result. 
Result so far: 14.0
Subtracting 344 from 374 leaves us with 30.
Bring next digit (0) of the dividend behind the 30 and repeat the process: 300 / 86

On to step 5:
When dividing 300 by 86, we get 3 with a remainder of 42.
The number 3 becomes the next digit in our result. 
Result so far: 143.0
If we subtract 258 from 300, we get 42.
Take the next digit (0) from the dividend and append it to 42, then repeat: 420 / 86

Advancing to step 6:
If we divide 420 by 86, we get 4 and a remainder of 76.
Write down 4 as next digit of the result. 
Result so far: 1434.0
If we subtract 344 from 420, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Moving on to step 7:
When dividing 760 by 86, we get 8 with a remainder of 72.
Write down 8 as next digit of the result. 
Result so far: 1434.8
Deduct 688 from 760 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 8:
The number 86 fits into 720 8 times, leaving a remainder of 32.
Use 8 as the next digit of our solution. 
Result so far: 1434.88
If we subtract 688 from 720, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

In conclusion, the division gives 1434.88 with a balance of 0.032.
