142160 divided by 86 
Let's see how many times 86 fits into 142160.

Advancing to step 1:
The number 86 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 86

Going ahead to step 2:
86 goes into 14 0 times with a remainder of 14.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 14 after subtracting 0 from 14.
Include the next digit (2) from the dividend after 14, then repeat: 142 / 86

Going ahead to step 3:
When dividing 142 by 86, we get 1 with a remainder of 56.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 86 from 142, we get 56.
Bring next digit (1) of the dividend behind the 56 and repeat the process: 561 / 86

Step 4:
561 divided by 86 is 6 with a remainder of 45.
Write down 6 as next digit of the result. 
Result so far: 16.0
Subtracting 516 from 561 leaves us with 45.
Fetch the next digit (6) from the dividend, attach it to 45 and continue: 456 / 86

On to step 5:
When dividing 456 by 86, we get 5 with a remainder of 26.
Use 5 as the next digit of our solution. 
Result so far: 165.0
If we subtract 430 from 456, we get 26.
Fetch the next digit (0) from the dividend, attach it to 26 and continue: 260 / 86

Advancing to step 6:
86 can be fit into 260 3 times, resulting in a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 1653.0
The remainder is 2 after subtracting 258 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 7:
86 can be fit into 20 0 times, resulting in a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 1653.0
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 8:
The number 86 fits into 200 2 times, leaving a remainder of 28.
Use 2 as the next digit of our solution. 
Result so far: 1653.02
Subtracting 172 from 200 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 9:
280 divided by 86 is 3 with a remainder of 22.
Record the quotient 3 as the next digit in the result. 
Result so far: 1653.023
If we take 258 away from 280, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 10:
220 divided by 86 is 2 with a remainder of 48.
Record the quotient 2 as the next digit in the result. 
Result so far: 1653.0232
The remainder is 48 after subtracting 172 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 11:
When dividing 480 by 86, we get 5 with a remainder of 50.
The next digit of our result is 5. 
Result so far: 1653.02325
If we subtract 430 from 480, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 12:
When dividing 500 by 86, we get 5 with a remainder of 70.
Record the quotient 5 as the next digit in the result. 
Result so far: 1653.023255
Subtract 430 from 500 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

After the division, we end up with 1653.023255 and a remainder of 7e-06.
