512144 divided by 87 
We want to divide 512144 by 87.

Going ahead to step 1:
When dividing 5 by 87, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 87

Advancing to step 2:
The number 87 fits into 51 0 times, leaving a remainder of 51.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 51 leaves us with 51.
Bring next digit (2) of the dividend behind the 51 and repeat the process: 512 / 87

Advancing to step 3:
87 can be fit into 512 5 times, resulting in a remainder of 77.
Write down 5 as next digit of the result. 
Result so far: 5.0
Deduct 435 from 512 and we're left with 77.
Take the next digit (1) from the dividend and append it to 77, then repeat: 771 / 87

On to step 4:
When dividing 771 by 87, we get 8 with a remainder of 75.
Put 8 as the next digit of the answer. 
Result so far: 58.0
Subtracting 696 from 771 leaves us with 75.
Bring next digit (4) of the dividend behind the 75 and repeat the process: 754 / 87

Advancing to step 5:
The number 87 fits into 754 8 times, leaving a remainder of 58.
The number 8 becomes the next digit in our result. 
Result so far: 588.0
The remainder is 58 after subtracting 696 from 754.
Take the next digit (4) from the dividend and append it to 58, then repeat: 584 / 87

Going ahead to step 6:
When dividing 584 by 87, we get 6 with a remainder of 62.
Use 6 as the next digit of our solution. 
Result so far: 5886.0
The remainder is 62 after subtracting 522 from 584.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 7:
87 can be fit into 620 7 times, resulting in a remainder of 11.
Record the quotient 7 as the next digit in the result. 
Result so far: 5886.7
If we take 609 away from 620, we end up 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 8:
When dividing 110 by 87, we get 1 with a remainder of 23.
The next digit of our result is 1. 
Result so far: 5886.71
The remainder is 23 after subtracting 87 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 9:
230 divided by 87 is 2 with a remainder of 56.
The number 2 becomes the next digit in our result. 
Result so far: 5886.712
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.

Let's proceed to step 10:
87 goes into 560 6 times with a remainder of 38.
The number 6 becomes the next digit in our result. 
Result so far: 5886.7126
Deduct 522 from 560 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 11:
If we divide 380 by 87, we get 4 and a remainder of 32.
The number 4 becomes the next digit in our result. 
Result so far: 5886.71264
Subtract 348 from 380 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 12:
If we divide 320 by 87, we get 3 and a remainder of 59.
Use 3 as the next digit of our solution. 
Result so far: 5886.712643
If we subtract 261 from 320, we get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Step 13:
590 divided by 87 is 6 with a remainder of 68.
The number 6 becomes the next digit in our result. 
Result so far: 5886.7126436
If we take 522 away from 590, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 14:
680 divided by 87 is 7 with a remainder of 71.
Put 7 as the next digit of the answer. 
Result so far: 5886.71264367
If we take 609 away from 680, we end up with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Our division results in 5886.71264367 with a remaining 7.1e-08.
