We look at the division of 123992 by 86 
Let's see how many times 86 fits into 123992.

Let's proceed to step 1:
1 divided by 86 is 0 with 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 / 86

On to step 2:
If we divide 12 by 86, we get 0 and a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Append the next digit (3) from the dividend to 12 and continue with: 123 / 86

Step 3:
86 goes into 123 1 times with a remainder of 37.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 86 from 123 to get 37.
Fetch the next digit (9) from the dividend, attach it to 37 and continue: 379 / 86

On to step 4:
86 goes into 379 4 times with a remainder of 35.
Use 4 as the next digit of our solution. 
Result so far: 14.0
If we subtract 344 from 379, we get 35.
Fetch the next digit (9) from the dividend, attach it to 35 and continue: 359 / 86

Going ahead to step 5:
If we divide 359 by 86, we get 4 and a remainder of 15.
Write down 4 as next digit of the result. 
Result so far: 144.0
The remainder is 15 after subtracting 344 from 359.
Take the next digit (2) from the dividend and append it to 15, then repeat: 152 / 86

On to step 6:
If we divide 152 by 86, we get 1 and a remainder of 66.
Put 1 as the next digit of the answer. 
Result so far: 1441.0
Deduct 86 from 152 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 7:
86 goes into 660 7 times with a remainder of 58.
The next digit of our result is 7. 
Result so far: 1441.7
If we take 602 away from 660, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 8:
If we divide 580 by 86, we get 6 and a remainder of 64.
Put 6 as the next digit of the answer. 
Result so far: 1441.76
Subtract 516 from 580 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 9:
The number 86 fits into 640 7 times, leaving a remainder of 38.
Record the quotient 7 as the next digit in the result. 
Result so far: 1441.767
If we subtract 602 from 640, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 10:
The number 86 fits into 380 4 times, leaving a remainder of 36.
Write down 4 as next digit of the result. 
Result so far: 1441.7674
Deduct 344 from 380 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 11:
360 divided by 86 is 4 with a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 1441.76744
The remainder is 16 after subtracting 344 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The quotient of the division is 1441.76744, and the remainder is 1.6e-05.
