We're dividing 12236889 by 575 
We want to divide 12236889 by 575.

Let's proceed to step 1:
575 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 575

On to step 2:
The number 575 fits into 12 0 times, leaving 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.
Bring next digit (2) of the dividend behind the 12 and repeat the process: 122 / 575

On to step 3:
575 can be fit into 122 0 times, resulting in a remainder of 122.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 122, we end up with 122.
Include the next digit (3) from the dividend after 122, then repeat: 1223 / 575

Advancing to step 4:
If we divide 1223 by 575, we get 2 and a remainder of 73.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 1150 from 1223, we get 73.
Append the next digit (6) from the dividend to 73 and continue with: 736 / 575

Moving on to step 5:
736 divided by 575 is 1 with a remainder of 161.
Use 1 as the next digit of our solution. 
Result so far: 21.0
The remainder is 161 after subtracting 575 from 736.
Append the next digit (8) from the dividend to 161 and continue with: 1618 / 575

Step 6:
575 goes into 1618 2 times with a remainder of 468.
Use 2 as the next digit of our solution. 
Result so far: 212.0
Deduct 1150 from 1618 and we're left with 468.
Take the next digit (8) from the dividend and append it to 468, then repeat: 4688 / 575

Moving on to step 7:
575 goes into 4688 8 times with a remainder of 88.
Write down 8 as next digit of the result. 
Result so far: 2128.0
Deduct 4600 from 4688 and we're left with 88.
Fetch the next digit (9) from the dividend, attach it to 88 and continue: 889 / 575

Moving on to step 8:
575 can be fit into 889 1 times, resulting in a remainder of 314.
Write down 1 as next digit of the result. 
Result so far: 21281.0
If we take 575 away from 889, we end up with 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

Let's proceed to step 9:
The number 575 fits into 3140 5 times, leaving a remainder of 265.
The number 5 becomes the next digit in our result. 
Result so far: 21281.5
Subtracting 2875 from 3140 leaves us with 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

Moving on to step 10:
575 can be fit into 2650 4 times, resulting in a remainder of 350.
Put 4 as the next digit of the answer. 
Result so far: 21281.54
Deduct 2300 from 2650 and we're left with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Advancing to step 11:
The number 575 fits into 3500 6 times, leaving a remainder of 50.
The number 6 becomes the next digit in our result. 
Result so far: 21281.546
Deduct 3450 from 3500 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 12:
575 goes into 500 0 times with a remainder of 500.
The number 0 becomes the next digit in our result. 
Result so far: 21281.546
If we take 0 away from 500, we end up with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Moving on to step 13:
575 can be fit into 5000 8 times, resulting in a remainder of 400.
Use 8 as the next digit of our solution. 
Result so far: 21281.54608
If we take 4600 away from 5000, we end up with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

On to step 14:
575 can be fit into 4000 6 times, resulting in a remainder of 550.
The next digit of our result is 6. 
Result so far: 21281.546086
If we subtract 3450 from 4000, we get 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Going ahead to step 15:
If we divide 5500 by 575, we get 9 and a remainder of 325.
Put 9 as the next digit of the answer. 
Result so far: 21281.5460869
Subtracting 5175 from 5500 leaves us with 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

On to step 16:
If we divide 3250 by 575, we get 5 and a remainder of 375.
The number 5 becomes the next digit in our result. 
Result so far: 21281.54608695
The remainder is 375 after subtracting 2875 from 3250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

After the division, we end up with 21281.54608695 and a remainder of 3.75e-07.
