We divide 140187 by 87
We're looking to find how many times 87 goes into 140187.

On to step 1:
The number 87 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 87

Advancing to step 2:
The number 87 fits into 14 0 times, leaving a remainder of 14.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 14 after subtracting 0 from 14.
Append the next digit (0) from the dividend to 14 and continue with: 140 / 87

Going ahead to step 3:
The number 87 fits into 140 1 times, leaving a remainder of 53.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 87 from 140 and we're left with 53.
Grab the next digit (1) from the dividend, add it to 53, then carry on: 531 / 87

Going ahead to step 4:
The number 87 fits into 531 6 times, leaving a remainder of 9.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
If we take 522 away from 531, we end up with 9.
Take the next digit (8) from the dividend and append it to 9, then repeat: 98 / 87

Going ahead to step 5:
98 divided by 87 is 1 with a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 161.0
The remainder is 11 after subtracting 87 from 98.
Include the next digit (7) from the dividend after 11, then repeat: 117 / 87

On to step 6:
117 divided by 87 is 1 with a remainder of 30.
Use 1 as the next digit of our solution. 
Result so far: 1611.0
Deduct 87 from 117 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 7:
If we divide 300 by 87, we get 3 and a remainder of 39.
Put 3 as the next digit of the answer. 
Result so far: 1611.3
If we subtract 261 from 300, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 8:
The number 87 fits into 390 4 times, leaving a remainder of 42.
Put 4 as the next digit of the answer. 
Result so far: 1611.34
If we take 348 away from 390, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 9:
87 goes into 420 4 times with a remainder of 72.
Put 4 as the next digit of the answer. 
Result so far: 1611.344
Subtract 348 from 420 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

The final outcome is 1611.344, with a leftover of 0.0072.
