12239051 ÷ 585 
Let's see how many times 585 fits into 12239051.

On to step 1:
If we divide 1 by 585, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 585

Advancing to step 2:
585 can be fit into 12 0 times, resulting in a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Take the next digit (2) from the dividend and append it to 12, then repeat: 122 / 585

Let's proceed to step 3:
122 divided by 585 is 0 with a remainder of 122.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 122 to get 122.
Bring next digit (3) of the dividend behind the 122 and repeat the process: 1223 / 585

Step 4:
When dividing 1223 by 585, we get 2 with a remainder of 53.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 1170 from 1223, we get 53.
Include the next digit (9) from the dividend after 53, then repeat: 539 / 585

Going ahead to step 5:
If we divide 539 by 585, we get 0 and a remainder of 539.
Write down 0 as next digit of the result. 
Result so far: 20.0
Subtract 0 from 539 to get 539.
Grab the next digit (0) from the dividend, add it to 539, then carry on: 5390 / 585

Advancing to step 6:
585 goes into 5390 9 times with a remainder of 125.
The next digit of our result is 9. 
Result so far: 209.0
Subtract 5265 from 5390 to get 125.
Append the next digit (5) from the dividend to 125 and continue with: 1255 / 585

Step 7:
585 goes into 1255 2 times with a remainder of 85.
Put 2 as the next digit of the answer. 
Result so far: 2092.0
The remainder is 85 after subtracting 1170 from 1255.
Bring next digit (1) of the dividend behind the 85 and repeat the process: 851 / 585

On to step 8:
When dividing 851 by 585, we get 1 with a remainder of 266.
The number 1 becomes the next digit in our result. 
Result so far: 20921.0
Subtract 585 from 851 to get 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

Step 9:
585 goes into 2660 4 times with a remainder of 320.
Use 4 as the next digit of our solution. 
Result so far: 20921.4
Subtract 2340 from 2660 to get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Let's proceed to step 10:
585 goes into 3200 5 times with a remainder of 275.
Record the quotient 5 as the next digit in the result. 
Result so far: 20921.45
The remainder is 275 after subtracting 2925 from 3200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Moving on to step 11:
585 goes into 2750 4 times with a remainder of 410.
The next digit of our result is 4. 
Result so far: 20921.454
Subtract 2340 from 2750 to get 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Going ahead to step 12:
The number 585 fits into 4100 7 times, leaving a remainder of 5.
Put 7 as the next digit of the answer. 
Result so far: 20921.4547
If we take 4095 away from 4100, we end up with 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 13:
If we divide 50 by 585, we get 0 and a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 20921.4547
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 14:
The number 585 fits into 500 0 times, leaving a remainder of 500.
The next digit of our result is 0. 
Result so far: 20921.4547
If we subtract 0 from 500, we get 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

The quotient of the division is 20921.4547, and the remainder is 5e-05.
