91066969 ÷ 266 
Our goal is to divide 91066969 by 266.

On to step 1:
The number 266 fits into 9 0 times, leaving a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 266

On to step 2:
266 can be fit into 91 0 times, resulting in a remainder of 91.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 91, we get 91.
Fetch the next digit (0) from the dividend, attach it to 91 and continue: 910 / 266

Going ahead to step 3:
266 can be fit into 910 3 times, resulting in a remainder of 112.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
The remainder is 112 after subtracting 798 from 910.
Bring next digit (6) of the dividend behind the 112 and repeat the process: 1126 / 266

Moving on to step 4:
When dividing 1126 by 266, we get 4 with a remainder of 62.
Record the quotient 4 as the next digit in the result. 
Result so far: 34.0
Subtracting 1064 from 1126 leaves us with 62.
Include the next digit (6) from the dividend after 62, then repeat: 626 / 266

Let's proceed to step 5:
626 divided by 266 is 2 with a remainder of 94.
The next digit of our result is 2. 
Result so far: 342.0
Deduct 532 from 626 and we're left with 94.
Include the next digit (9) from the dividend after 94, then repeat: 949 / 266

Moving on to step 6:
949 divided by 266 is 3 with a remainder of 151.
Put 3 as the next digit of the answer. 
Result so far: 3423.0
The remainder is 151 after subtracting 798 from 949.
Include the next digit (6) from the dividend after 151, then repeat: 1516 / 266

Advancing to step 7:
266 goes into 1516 5 times with a remainder of 186.
Write down 5 as next digit of the result. 
Result so far: 34235.0
Deduct 1330 from 1516 and we're left with 186.
Include the next digit (9) from the dividend after 186, then repeat: 1869 / 266

Moving on to step 8:
If we divide 1869 by 266, we get 7 and a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 342357.0
The remainder is 7 after subtracting 1862 from 1869.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 9:
If we divide 70 by 266, we get 0 and a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 342357.0
Subtract 0 from 70 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 10:
The number 266 fits into 700 2 times, leaving a remainder of 168.
Use 2 as the next digit of our solution. 
Result so far: 342357.02
The remainder is 168 after subtracting 532 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Advancing to step 11:
The number 266 fits into 1680 6 times, leaving a remainder of 84.
Put 6 as the next digit of the answer. 
Result so far: 342357.026
The remainder is 84 after subtracting 1596 from 1680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Going ahead to step 12:
840 divided by 266 is 3 with a remainder of 42.
Write down 3 as next digit of the result. 
Result so far: 342357.0263
Deduct 798 from 840 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 13:
266 can be fit into 420 1 times, resulting in a remainder of 154.
Put 1 as the next digit of the answer. 
Result so far: 342357.02631
Subtract 266 from 420 to 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.

On to step 14:
The number 266 fits into 1540 5 times, leaving a remainder of 210.
The number 5 becomes the next digit in our result. 
Result so far: 342357.026315
Deduct 1330 from 1540 and we're left 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.

Moving on to step 15:
The number 266 fits into 2100 7 times, leaving a remainder of 238.
The next digit of our result is 7. 
Result so far: 342357.0263157
If we take 1862 away from 2100, we end up with 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Step 16:
The number 266 fits into 2380 8 times, leaving a remainder of 252.
Write down 8 as next digit of the result. 
Result so far: 342357.02631578
Subtract 2128 from 2380 to get 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

After the division, we end up with 342357.02631578 and a remainder of 2.52e-07.
