1225276 divided by 289 
Our goal is to divide 1225276 by 289.

Step 1:
1 divided by 289 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 289

Going ahead to step 2:
If we divide 12 by 289, we get 0 and a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Fetch the next digit (2) from the dividend, attach it to 12 and continue: 122 / 289

Moving on to step 3:
The number 289 fits into 122 0 times, leaving a remainder of 122.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 122 and we're left with 122.
Fetch the next digit (5) from the dividend, attach it to 122 and continue: 1225 / 289

On to step 4:
289 can be fit into 1225 4 times, resulting in a remainder of 69.
The next digit of our result is 4. 
Result so far: 4.0
Deduct 1156 from 1225 and we're left with 69.
Append the next digit (2) from the dividend to 69 and continue with: 692 / 289

Advancing to step 5:
692 divided by 289 is 2 with a remainder of 114.
The number 2 becomes the next digit in our result. 
Result so far: 42.0
Deduct 578 from 692 and we're left with 114.
Include the next digit (7) from the dividend after 114, then repeat: 1147 / 289

Advancing to step 6:
289 goes into 1147 3 times with a remainder of 280.
The number 3 becomes the next digit in our result. 
Result so far: 423.0
If we take 867 away from 1147, we end up with 280.
Include the next digit (6) from the dividend after 280, then repeat: 2806 / 289

Advancing to step 7:
289 can be fit into 2806 9 times, resulting in a remainder of 205.
Put 9 as the next digit of the answer. 
Result so far: 4239.0
If we take 2601 away from 2806, we end up with 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Let's proceed to step 8:
If we divide 2050 by 289, we get 7 and a remainder of 27.
Use 7 as the next digit of our solution. 
Result so far: 4239.7
If we take 2023 away from 2050, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 9:
289 can be fit into 270 0 times, resulting in a remainder of 270.
Use 0 as the next digit of our solution. 
Result so far: 4239.7
Subtract 0 from 270 to get 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Step 10:
If we divide 2700 by 289, we get 9 and a remainder of 99.
Write down 9 as next digit of the result. 
Result so far: 4239.709
Subtract 2601 from 2700 to get 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

On to step 11:
If we divide 990 by 289, we get 3 and a remainder of 123.
Put 3 as the next digit of the answer. 
Result so far: 4239.7093
Subtract 867 from 990 to get 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

On to step 12:
1230 divided by 289 is 4 with a remainder of 74.
Use 4 as the next digit of our solution. 
Result so far: 4239.70934
The remainder is 74 after subtracting 1156 from 1230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Step 13:
The number 289 fits into 740 2 times, leaving a remainder of 162.
The next digit of our result is 2. 
Result so far: 4239.709342
If we take 578 away from 740, we end up with 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

On to step 14:
When dividing 1620 by 289, we get 5 with a remainder of 175.
The number 5 becomes the next digit in our result. 
Result so far: 4239.7093425
Deduct 1445 from 1620 and we're left with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

On to step 15:
The number 289 fits into 1750 6 times, leaving a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 4239.70934256
The remainder is 16 after subtracting 1734 from 1750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Our division results in 4239.70934256 with a remaining 1.6e-08.
