We look at the division of 839189 by 87 
Let's see how many times 87 fits into 839189.

Step 1:
8 divided by 87 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (3) from the dividend, attach it to 8 and continue: 83 / 87

On to step 2:
87 goes into 83 0 times with a remainder of 83.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 83 and we're left with 83.
Bring next digit (9) of the dividend behind the 83 and repeat the process: 839 / 87

Let's proceed to step 3:
87 can be fit into 839 9 times, resulting in a remainder of 56.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtracting 783 from 839 leaves us with 56.
Append the next digit (1) from the dividend to 56 and continue with: 561 / 87

On to step 4:
When dividing 561 by 87, we get 6 with a remainder of 39.
Record the quotient 6 as the next digit in the result. 
Result so far: 96.0
Subtract 522 from 561 to get 39.
Take the next digit (8) from the dividend and append it to 39, then repeat: 398 / 87

On to step 5:
87 goes into 398 4 times with a remainder of 50.
Use 4 as the next digit of our solution. 
Result so far: 964.0
If we subtract 348 from 398, we get 50.
Include the next digit (9) from the dividend after 50, then repeat: 509 / 87

On to step 6:
If we divide 509 by 87, we get 5 and a remainder of 74.
Record the quotient 5 as the next digit in the result. 
Result so far: 9645.0
Subtracting 435 from 509 leaves us with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

On to step 7:
87 goes into 740 8 times with a remainder of 44.
Write down 8 as next digit of the result. 
Result so far: 9645.8
The remainder is 44 after subtracting 696 from 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 8:
87 goes into 440 5 times with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 9645.85
If we subtract 435 from 440, we 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.

Moving on to step 9:
87 can be fit into 50 0 times, resulting in a remainder of 50.
The next digit of our result is 0. 
Result so far: 9645.85
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.

Advancing to step 10:
500 divided by 87 is 5 with a remainder of 65.
The next digit of our result is 5. 
Result so far: 9645.8505
If we subtract 435 from 500, we get 65.
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 11:
If we divide 650 by 87, we get 7 and a remainder of 41.
Record the quotient 7 as the next digit in the result. 
Result so far: 9645.85057
Deduct 609 from 650 and we're left with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Advancing to step 12:
The number 87 fits into 410 4 times, leaving a remainder of 62.
The number 4 becomes the next digit in our result. 
Result so far: 9645.850574
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.

Going ahead to step 13:
When dividing 620 by 87, we get 7 with a remainder of 11.
Record the quotient 7 as the next digit in the result. 
Result so far: 9645.8505747
Deduct 609 from 620 and we're left 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.

On to step 14:
The number 87 fits into 110 1 times, leaving a remainder of 23.
Use 1 as the next digit of our solution. 
Result so far: 9645.85057471
If we subtract 87 from 110, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

The quotient of the division is 9645.85057471, and the remainder is 2.3e-08.
