We look at the division of 15887399 by 684 
We're looking to find how many times 684 goes into 15887399.

Going ahead to step 1:
684 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 684

Moving on to step 2:
The number 684 fits into 15 0 times, leaving a remainder of 15.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 15 to get 15.
Take the next digit (8) from the dividend and append it to 15, then repeat: 158 / 684

Step 3:
When dividing 158 by 684, we get 0 with a remainder of 158.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 158, we get 158.
Fetch the next digit (8) from the dividend, attach it to 158 and continue: 1588 / 684

Moving on to step 4:
The number 684 fits into 1588 2 times, leaving a remainder of 220.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 1368 away from 1588, we end up with 220.
Take the next digit (7) from the dividend and append it to 220, then repeat: 2207 / 684

Step 5:
If we divide 2207 by 684, we get 3 and a remainder of 155.
Write down 3 as next digit of the result. 
Result so far: 23.0
If we subtract 2052 from 2207, we get 155.
Fetch the next digit (3) from the dividend, attach it to 155 and continue: 1553 / 684

Step 6:
684 goes into 1553 2 times with a remainder of 185.
The number 2 becomes the next digit in our result. 
Result so far: 232.0
Deduct 1368 from 1553 and we're left with 185.
Include the next digit (9) from the dividend after 185, then repeat: 1859 / 684

Let's proceed to step 7:
If we divide 1859 by 684, we get 2 and a remainder of 491.
Use 2 as the next digit of our solution. 
Result so far: 2322.0
Subtracting 1368 from 1859 leaves us with 491.
Take the next digit (9) from the dividend and append it to 491, then repeat: 4919 / 684

Step 8:
When dividing 4919 by 684, we get 7 with a remainder of 131.
The number 7 becomes the next digit in our result. 
Result so far: 23227.0
If we subtract 4788 from 4919, we get 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

On to step 9:
The number 684 fits into 1310 1 times, leaving a remainder of 626.
Write down 1 as next digit of the result. 
Result so far: 23227.1
The remainder is 626 after subtracting 684 from 1310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6260, and continue the process.

Going ahead to step 10:
The number 684 fits into 6260 9 times, leaving a remainder of 104.
The next digit of our result is 9. 
Result so far: 23227.19
Subtracting 6156 from 6260 leaves us with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

On to step 11:
When dividing 1040 by 684, we get 1 with a remainder of 356.
Put 1 as the next digit of the answer. 
Result so far: 23227.191
Subtract 684 from 1040 to get 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Advancing to step 12:
If we divide 3560 by 684, we get 5 and a remainder of 140.
Write down 5 as next digit of the result. 
Result so far: 23227.1915
The remainder is 140 after subtracting 3420 from 3560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Advancing to step 13:
The number 684 fits into 1400 2 times, leaving a remainder of 32.
The number 2 becomes the next digit in our result. 
Result so far: 23227.19152
If we subtract 1368 from 1400, we 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.

Let's proceed to step 14:
684 goes into 320 0 times with a remainder of 320.
Record the quotient 0 as the next digit in the result. 
Result so far: 23227.19152
If we take 0 away from 320, we end up with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Moving on to step 15:
If we divide 3200 by 684, we get 4 and a remainder of 464.
Record the quotient 4 as the next digit in the result. 
Result so far: 23227.1915204
The remainder is 464 after subtracting 2736 from 3200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

Step 16:
The number 684 fits into 4640 6 times, leaving a remainder of 536.
Record the quotient 6 as the next digit in the result. 
Result so far: 23227.19152046
If we subtract 4104 from 4640, we get 536.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5360, and continue the process.

The final result is 23227.19152046 with a remainder of 5.36e-07.
