We divide 12915889 by 266
Our goal is to divide 12915889 by 266.

Going ahead to step 1:
When dividing 1 by 266, we get 0 with 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.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 266

Step 2:
12 divided by 266 is 0 with a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Grab the next digit (9) from the dividend, add it to 12, then carry on: 129 / 266

Advancing to step 3:
129 divided by 266 is 0 with a remainder of 129.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 129 to get 129.
Bring next digit (1) of the dividend behind the 129 and repeat the process: 1291 / 266

Advancing to step 4:
1291 divided by 266 is 4 with a remainder of 227.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtract 1064 from 1291 to get 227.
Fetch the next digit (5) from the dividend, attach it to 227 and continue: 2275 / 266

Going ahead to step 5:
The number 266 fits into 2275 8 times, leaving a remainder of 147.
The next digit of our result is 8. 
Result so far: 48.0
The remainder is 147 after subtracting 2128 from 2275.
Append the next digit (8) from the dividend to 147 and continue with: 1478 / 266

Let's proceed to step 6:
266 can be fit into 1478 5 times, resulting in a remainder of 148.
Use 5 as the next digit of our solution. 
Result so far: 485.0
Subtracting 1330 from 1478 leaves us with 148.
Bring next digit (8) of the dividend behind the 148 and repeat the process: 1488 / 266

Let's proceed to step 7:
266 can be fit into 1488 5 times, resulting in a remainder of 158.
Put 5 as the next digit of the answer. 
Result so far: 4855.0
If we subtract 1330 from 1488, we get 158.
Grab the next digit (9) from the dividend, add it to 158, then carry on: 1589 / 266

Moving on to step 8:
266 can be fit into 1589 5 times, resulting in a remainder of 259.
The number 5 becomes the next digit in our result. 
Result so far: 48555.0
Deduct 1330 from 1589 and we're left with 259.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2590, and continue the process.

Advancing to step 9:
266 can be fit into 2590 9 times, resulting in a remainder of 196.
The next digit of our result is 9. 
Result so far: 48555.9
The remainder is 196 after subtracting 2394 from 2590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Let's proceed to step 10:
When dividing 1960 by 266, we get 7 with a remainder of 98.
The number 7 becomes the next digit in our result. 
Result so far: 48555.97
The remainder is 98 after subtracting 1862 from 1960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Step 11:
980 divided by 266 is 3 with a remainder of 182.
Write down 3 as next digit of the result. 
Result so far: 48555.973
Subtracting 798 from 980 leaves us with 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

Going ahead to step 12:
The number 266 fits into 1820 6 times, leaving a remainder of 224.
Use 6 as the next digit of our solution. 
Result so far: 48555.9736
The remainder is 224 after subtracting 1596 from 1820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

On to step 13:
266 can be fit into 2240 8 times, resulting in a remainder of 112.
Use 8 as the next digit of our solution. 
Result so far: 48555.97368
Subtract 2128 from 2240 to get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Advancing to step 14:
If we divide 1120 by 266, we get 4 and a remainder of 56.
Use 4 as the next digit of our solution. 
Result so far: 48555.973684
The remainder is 56 after subtracting 1064 from 1120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 15:
560 divided by 266 is 2 with a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 48555.9736842
The remainder is 28 after subtracting 532 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 16:
266 goes into 280 1 times with a remainder of 14.
Put 1 as the next digit of the answer. 
Result so far: 48555.97368421
Deduct 266 from 280 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

After the division, we end up with 48555.97368421 and a remainder of 1.4e-08.
