76523900 divided by 450 
Let's see how many times 450 fits into 76523900.

Let's proceed to step 1:
When dividing 7 by 450, we get 0 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.
Include the next digit (6) from the dividend after 7, then repeat: 76 / 450

Going ahead to step 2:
450 goes into 76 0 times with a remainder of 76.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 76 and we're left with 76.
Include the next digit (5) from the dividend after 76, then repeat: 765 / 450

Advancing to step 3:
If we divide 765 by 450, we get 1 and a remainder of 315.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 450 from 765 and we're left with 315.
Fetch the next digit (2) from the dividend, attach it to 315 and continue: 3152 / 450

Step 4:
When dividing 3152 by 450, we get 7 with a remainder of 2.
The next digit of our result is 7. 
Result so far: 17.0
Subtract 3150 from 3152 to get 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 450

Advancing to step 5:
450 can be fit into 23 0 times, resulting in a remainder of 23.
Use 0 as the next digit of our solution. 
Result so far: 170.0
Deduct 0 from 23 and we're left with 23.
Append the next digit (9) from the dividend to 23 and continue with: 239 / 450

Let's proceed to step 6:
239 divided by 450 is 0 with a remainder of 239.
The number 0 becomes the next digit in our result. 
Result so far: 1700.0
Subtract 0 from 239 to get 239.
Bring next digit (0) of the dividend behind the 239 and repeat the process: 2390 / 450

Step 7:
450 can be fit into 2390 5 times, resulting in a remainder of 140.
Record the quotient 5 as the next digit in the result. 
Result so far: 17005.0
If we take 2250 away from 2390, we end up with 140.
Bring next digit (0) of the dividend behind the 140 and repeat the process: 1400 / 450

Moving on to step 8:
If we divide 1400 by 450, we get 3 and a remainder of 50.
The number 3 becomes the next digit in our result. 
Result so far: 170053.0
If we take 1350 away from 1400, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 9:
When dividing 500 by 450, we get 1 with a remainder of 50.
Record the quotient 1 as the next digit in the result. 
Result so far: 170053.1
Subtract 450 from 500 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 10:
450 can be fit into 500 1 times, resulting in a remainder of 50.
Record the quotient 1 as the next digit in the result. 
Result so far: 170053.11
The remainder is 50 after subtracting 450 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

The final result is 170053.11 with a remainder of 0.05.
