Let's divide 142116 by 86
Let's see how many times 86 fits into 142116.

Advancing to step 1:
If we divide 1 by 86, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 86

On to step 2:
86 can be fit into 14 0 times, resulting in a remainder of 14.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 14, we get 14.
Bring next digit (2) of the dividend behind the 14 and repeat the process: 142 / 86

Advancing to step 3:
142 divided by 86 is 1 with a remainder of 56.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 56 after subtracting 86 from 142.
Grab the next digit (1) from the dividend, add it to 56, then carry on: 561 / 86

On to step 4:
86 can be fit into 561 6 times, resulting in a remainder of 45.
Put 6 as the next digit of the answer. 
Result so far: 16.0
If we subtract 516 from 561, we get 45.
Fetch the next digit (1) from the dividend, attach it to 45 and continue: 451 / 86

Going ahead to step 5:
If we divide 451 by 86, we get 5 and a remainder of 21.
The number 5 becomes the next digit in our result. 
Result so far: 165.0
Subtract 430 from 451 to get 21.
Append the next digit (6) from the dividend to 21 and continue with: 216 / 86

Advancing to step 6:
86 can be fit into 216 2 times, resulting in a remainder of 44.
Use 2 as the next digit of our solution. 
Result so far: 1652.0
Subtract 172 from 216 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 7:
86 can be fit into 440 5 times, resulting in a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 1652.5
Deduct 430 from 440 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
When dividing 100 by 86, we get 1 with a remainder of 14.
Use 1 as the next digit of our solution. 
Result so far: 1652.51
The remainder is 14 after subtracting 86 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 9:
86 can be fit into 140 1 times, resulting in a remainder of 54.
Write down 1 as next digit of the result. 
Result so far: 1652.511
Deduct 86 from 140 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

After the division, we end up with 1652.511 and a remainder of 0.0054.
