5125456 divided by 266 
Our goal is to divide 5125456 by 266.

Moving on to step 1:
266 can be fit into 5 0 times, resulting in a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 266

Moving on to step 2:
51 divided by 266 is 0 with a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 51, we get 51.
Append the next digit (2) from the dividend to 51 and continue with: 512 / 266

Going ahead to step 3:
When dividing 512 by 266, we get 1 with a remainder of 246.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 266 from 512, we get 246.
Fetch the next digit (5) from the dividend, attach it to 246 and continue: 2465 / 266

Step 4:
If we divide 2465 by 266, we get 9 and a remainder of 71.
Use 9 as the next digit of our solution. 
Result so far: 19.0
Subtract 2394 from 2465 to get 71.
Bring next digit (4) of the dividend behind the 71 and repeat the process: 714 / 266

On to step 5:
266 can be fit into 714 2 times, resulting in a remainder of 182.
The next digit of our result is 2. 
Result so far: 192.0
If we take 532 away from 714, we end up with 182.
Bring next digit (5) of the dividend behind the 182 and repeat the process: 1825 / 266

Moving on to step 6:
If we divide 1825 by 266, we get 6 and a remainder of 229.
Put 6 as the next digit of the answer. 
Result so far: 1926.0
If we subtract 1596 from 1825, we get 229.
Include the next digit (6) from the dividend after 229, then repeat: 2296 / 266

On to step 7:
When dividing 2296 by 266, we get 8 with a remainder of 168.
Put 8 as the next digit of the answer. 
Result so far: 19268.0
Deduct 2128 from 2296 and we're left with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

On to step 8:
1680 divided by 266 is 6 with a remainder of 84.
Use 6 as the next digit of our solution. 
Result so far: 19268.6
Deduct 1596 from 1680 and we're left with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Moving on to step 9:
If we divide 840 by 266, we get 3 and a remainder of 42.
Put 3 as the next digit of the answer. 
Result so far: 19268.63
If we subtract 798 from 840, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 10:
420 divided by 266 is 1 with a remainder of 154.
Record the quotient 1 as the next digit in the result. 
Result so far: 19268.631
If we subtract 266 from 420, we get 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Step 11:
If we divide 1540 by 266, we get 5 and a remainder of 210.
Put 5 as the next digit of the answer. 
Result so far: 19268.6315
If we take 1330 away from 1540, we end up with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Advancing to step 12:
266 can be fit into 2100 7 times, resulting in a remainder of 238.
Put 7 as the next digit of the answer. 
Result so far: 19268.63157
The remainder is 238 after subtracting 1862 from 2100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Advancing to step 13:
2380 divided by 266 is 8 with a remainder of 252.
Put 8 as the next digit of the answer. 
Result so far: 19268.631578
Deduct 2128 from 2380 and we're left with 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Going ahead to step 14:
The number 266 fits into 2520 9 times, leaving a remainder of 126.
The number 9 becomes the next digit in our result. 
Result so far: 19268.6315789
The remainder is 126 after subtracting 2394 from 2520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Let's proceed to step 15:
266 goes into 1260 4 times with a remainder of 196.
The number 4 becomes the next digit in our result. 
Result so far: 19268.63157894
If we subtract 1064 from 1260, we get 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Our division results in 19268.63157894 with a remaining 1.96e-07.
