We're dividing 15663123 by 586 
Let's see how many times 586 fits into 15663123.

Moving on to step 1:
If we divide 1 by 586, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 586

On to step 2:
586 can be fit into 15 0 times, resulting in a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 15 to get 15.
Append the next digit (6) from the dividend to 15 and continue with: 156 / 586

Advancing to step 3:
If we divide 156 by 586, we get 0 and a remainder of 156.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 156, we end up with 156.
Take the next digit (6) from the dividend and append it to 156, then repeat: 1566 / 586

Moving on to step 4:
If we divide 1566 by 586, we get 2 and a remainder of 394.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 1172 away from 1566, we end up with 394.
Fetch the next digit (3) from the dividend, attach it to 394 and continue: 3943 / 586

On to step 5:
When dividing 3943 by 586, we get 6 with a remainder of 427.
Write down 6 as next digit of the result. 
Result so far: 26.0
Subtracting 3516 from 3943 leaves us with 427.
Bring next digit (1) of the dividend behind the 427 and repeat the process: 4271 / 586

Let's proceed to step 6:
586 goes into 4271 7 times with a remainder of 169.
Record the quotient 7 as the next digit in the result. 
Result so far: 267.0
If we take 4102 away from 4271, we end up with 169.
Include the next digit (2) from the dividend after 169, then repeat: 1692 / 586

Advancing to step 7:
If we divide 1692 by 586, we get 2 and a remainder of 520.
The number 2 becomes the next digit in our result. 
Result so far: 2672.0
The remainder is 520 after subtracting 1172 from 1692.
Take the next digit (3) from the dividend and append it to 520, then repeat: 5203 / 586

Moving on to step 8:
5203 divided by 586 is 8 with a remainder of 515.
Record the quotient 8 as the next digit in the result. 
Result so far: 26728.0
If we subtract 4688 from 5203, we get 515.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5150, and continue the process.

Going ahead to step 9:
5150 divided by 586 is 8 with a remainder of 462.
The next digit of our result is 8. 
Result so far: 26728.8
Subtract 4688 from 5150 to get 462.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4620, and continue the process.

Advancing to step 10:
586 can be fit into 4620 7 times, resulting in a remainder of 518.
Record the quotient 7 as the next digit in the result. 
Result so far: 26728.87
Deduct 4102 from 4620 and we're left with 518.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5180, and continue the process.

Going ahead to step 11:
If we divide 5180 by 586, we get 8 and a remainder of 492.
The number 8 becomes the next digit in our result. 
Result so far: 26728.878
Subtracting 4688 from 5180 leaves us with 492.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4920, and continue the process.

Step 12:
The number 586 fits into 4920 8 times, leaving a remainder of 232.
Write down 8 as next digit of the result. 
Result so far: 26728.8788
Subtracting 4688 from 4920 leaves us with 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Our division results in 26728.8788 with a remaining 0.00232.
