We look at the division of 76421544 by 266 
We want to divide 76421544 by 266.

Advancing to step 1:
266 goes into 7 0 times with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (6) from the dividend, attach it to 7 and continue: 76 / 266

Advancing to step 2:
When dividing 76 by 266, we get 0 with a remainder of 76.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 76 to get 76.
Take the next digit (4) from the dividend and append it to 76, then repeat: 764 / 266

Let's proceed to step 3:
The number 266 fits into 764 2 times, leaving a remainder of 232.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 532 from 764 and we're left with 232.
Take the next digit (2) from the dividend and append it to 232, then repeat: 2322 / 266

On to step 4:
266 goes into 2322 8 times with a remainder of 194.
Put 8 as the next digit of the answer. 
Result so far: 28.0
The remainder is 194 after subtracting 2128 from 2322.
Take the next digit (1) from the dividend and append it to 194, then repeat: 1941 / 266

Going ahead to step 5:
When dividing 1941 by 266, we get 7 with a remainder of 79.
Write down 7 as next digit of the result. 
Result so far: 287.0
Deduct 1862 from 1941 and we're left with 79.
Bring next digit (5) of the dividend behind the 79 and repeat the process: 795 / 266

Let's proceed to step 6:
795 divided by 266 is 2 with a remainder of 263.
Write down 2 as next digit of the result. 
Result so far: 2872.0
Deduct 532 from 795 and we're left with 263.
Append the next digit (4) from the dividend to 263 and continue with: 2634 / 266

Going ahead to step 7:
When dividing 2634 by 266, we get 9 with a remainder of 240.
Put 9 as the next digit of the answer. 
Result so far: 28729.0
Subtract 2394 from 2634 to get 240.
Append the next digit (4) from the dividend to 240 and continue with: 2404 / 266

Going ahead to step 8:
If we divide 2404 by 266, we get 9 and a remainder of 10.
The number 9 becomes the next digit in our result. 
Result so far: 287299.0
Subtracting 2394 from 2404 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 9:
266 can be fit into 100 0 times, resulting in a remainder of 100.
Record the quotient 0 as the next digit in the result. 
Result so far: 287299.0
If we take 0 away from 100, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Step 10:
266 goes into 1000 3 times with a remainder of 202.
Record the quotient 3 as the next digit in the result. 
Result so far: 287299.03
If we take 798 away from 1000, we end up with 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Step 11:
266 goes into 2020 7 times with a remainder of 158.
The number 7 becomes the next digit in our result. 
Result so far: 287299.037
Subtract 1862 from 2020 to get 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Step 12:
The number 266 fits into 1580 5 times, leaving a remainder of 250.
The next digit of our result is 5. 
Result so far: 287299.0375
If we take 1330 away from 1580, we end up with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Going ahead to step 13:
If we divide 2500 by 266, we get 9 and a remainder of 106.
Record the quotient 9 as the next digit in the result. 
Result so far: 287299.03759
If we subtract 2394 from 2500, we get 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

On to step 14:
266 can be fit into 1060 3 times, resulting in a remainder of 262.
Put 3 as the next digit of the answer. 
Result so far: 287299.037593
Deduct 798 from 1060 and we're left with 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

Step 15:
266 can be fit into 2620 9 times, resulting in a remainder of 226.
The number 9 becomes the next digit in our result. 
Result so far: 287299.0375939
The remainder is 226 after subtracting 2394 from 2620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

On to step 16:
2260 divided by 266 is 8 with a remainder of 132.
Record the quotient 8 as the next digit in the result. 
Result so far: 287299.03759398
If we take 2128 away from 2260, we end up with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

The quotient of the division is 287299.03759398, and the remainder is 1.32e-07.
