Let's divide 12587813 by 87
We want to divide 12587813 by 87.

Let's proceed to step 1:
1 divided by 87 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 87

Let's proceed to step 2:
12 divided by 87 is 0 with a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Grab the next digit (5) from the dividend, add it to 12, then carry on: 125 / 87

Going ahead to step 3:
If we divide 125 by 87, we get 1 and a remainder of 38.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 87 from 125 leaves us with 38.
Take the next digit (8) from the dividend and append it to 38, then repeat: 388 / 87

Going ahead to step 4:
388 divided by 87 is 4 with a remainder of 40.
Put 4 as the next digit of the answer. 
Result so far: 14.0
Subtract 348 from 388 to get 40.
Grab the next digit (7) from the dividend, add it to 40, then carry on: 407 / 87

Going ahead to step 5:
87 can be fit into 407 4 times, resulting in a remainder of 59.
Use 4 as the next digit of our solution. 
Result so far: 144.0
If we take 348 away from 407, we end up with 59.
Append the next digit (8) from the dividend to 59 and continue with: 598 / 87

Moving on to step 6:
598 divided by 87 is 6 with a remainder of 76.
Use 6 as the next digit of our solution. 
Result so far: 1446.0
If we take 522 away from 598, we end up with 76.
Grab the next digit (1) from the dividend, add it to 76, then carry on: 761 / 87

Going ahead to step 7:
When dividing 761 by 87, we get 8 with a remainder of 65.
The next digit of our result is 8. 
Result so far: 14468.0
Subtract 696 from 761 to get 65.
Grab the next digit (3) from the dividend, add it to 65, then carry on: 653 / 87

On to step 8:
87 can be fit into 653 7 times, resulting in a remainder of 44.
Record the quotient 7 as the next digit in the result. 
Result so far: 144687.0
If we take 609 away from 653, we end up with 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 9:
When dividing 440 by 87, we get 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 144687.5
Subtract 435 from 440 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 10:
50 divided by 87 is 0 with a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 144687.5
Subtract 0 from 50 to 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.

Going ahead to step 11:
If we divide 500 by 87, we get 5 and a remainder of 65.
Record the quotient 5 as the next digit in the result. 
Result so far: 144687.505
The remainder is 65 after subtracting 435 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Moving on to step 12:
If we divide 650 by 87, we get 7 and a remainder of 41.
Put 7 as the next digit of the answer. 
Result so far: 144687.5057
The remainder is 41 after subtracting 609 from 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

On to step 13:
If we divide 410 by 87, we get 4 and a remainder of 62.
Record the quotient 4 as the next digit in the result. 
Result so far: 144687.50574
Subtract 348 from 410 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Moving on to step 14:
87 goes into 620 7 times with a remainder of 11.
The number 7 becomes the next digit in our result. 
Result so far: 144687.505747
Subtracting 609 from 620 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 15:
87 goes into 110 1 times with a remainder of 23.
Put 1 as the next digit of the answer. 
Result so far: 144687.5057471
Subtracting 87 from 110 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 16:
230 divided by 87 is 2 with a remainder of 56.
Record the quotient 2 as the next digit in the result. 
Result so far: 144687.50574712
If we take 174 away from 230, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

The final result is 144687.50574712 with a remainder of 5.6e-08.
