45578216 divided by 266 
We want to divide 45578216 by 266.

Step 1:
The number 266 fits into 4 0 times, leaving a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 266

On to step 2:
When dividing 45 by 266, we get 0 with a remainder of 45.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 45 to get 45.
Append the next digit (5) from the dividend to 45 and continue with: 455 / 266

On to step 3:
266 goes into 455 1 times with a remainder of 189.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 189 after subtracting 266 from 455.
Include the next digit (7) from the dividend after 189, then repeat: 1897 / 266

Step 4:
If we divide 1897 by 266, we get 7 and a remainder of 35.
Write down 7 as next digit of the result. 
Result so far: 17.0
Subtract 1862 from 1897 to get 35.
Include the next digit (8) from the dividend after 35, then repeat: 358 / 266

Advancing to step 5:
266 can be fit into 358 1 times, resulting in a remainder of 92.
Use 1 as the next digit of our solution. 
Result so far: 171.0
Deduct 266 from 358 and we're left with 92.
Grab the next digit (2) from the dividend, add it to 92, then carry on: 922 / 266

Moving on to step 6:
When dividing 922 by 266, we get 3 with a remainder of 124.
The number 3 becomes the next digit in our result. 
Result so far: 1713.0
Subtract 798 from 922 to get 124.
Grab the next digit (1) from the dividend, add it to 124, then carry on: 1241 / 266

On to step 7:
When dividing 1241 by 266, we get 4 with a remainder of 177.
Use 4 as the next digit of our solution. 
Result so far: 17134.0
If we subtract 1064 from 1241, we get 177.
Append the next digit (6) from the dividend to 177 and continue with: 1776 / 266

Going ahead to step 8:
If we divide 1776 by 266, we get 6 and a remainder of 180.
The number 6 becomes the next digit in our result. 
Result so far: 171346.0
If we subtract 1596 from 1776, we get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

On to step 9:
When dividing 1800 by 266, we get 6 with a remainder of 204.
Record the quotient 6 as the next digit in the result. 
Result so far: 171346.6
Deduct 1596 from 1800 and we're left with 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Advancing to step 10:
The number 266 fits into 2040 7 times, leaving a remainder of 178.
Put 7 as the next digit of the answer. 
Result so far: 171346.67
Subtract 1862 from 2040 to get 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

Step 11:
If we divide 1780 by 266, we get 6 and a remainder of 184.
Record the quotient 6 as the next digit in the result. 
Result so far: 171346.676
Subtract 1596 from 1780 to get 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

On to step 12:
1840 divided by 266 is 6 with a remainder of 244.
Record the quotient 6 as the next digit in the result. 
Result so far: 171346.6766
If we subtract 1596 from 1840, we get 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

The quotient of the division is 171346.6766, and the remainder is 0.00244.
