We divide 81805932 by 225
We want to figure out the number of times 81805932 can be divided by 225.

Step 1:
225 can be fit into 8 0 times, resulting in a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 225

On to step 2:
81 divided by 225 is 0 with a remainder of 81.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 81, we end up with 81.
Take the next digit (8) from the dividend and append it to 81, then repeat: 818 / 225

Going ahead to step 3:
225 can be fit into 818 3 times, resulting in a remainder of 143.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtract 675 from 818 to get 143.
Bring next digit (0) of the dividend behind the 143 and repeat the process: 1430 / 225

Going ahead to step 4:
The number 225 fits into 1430 6 times, leaving a remainder of 80.
The number 6 becomes the next digit in our result. 
Result so far: 36.0
If we take 1350 away from 1430, we end up with 80.
Include the next digit (5) from the dividend after 80, then repeat: 805 / 225

Advancing to step 5:
If we divide 805 by 225, we get 3 and a remainder of 130.
Write down 3 as next digit of the result. 
Result so far: 363.0
Deduct 675 from 805 and we're left with 130.
Include the next digit (9) from the dividend after 130, then repeat: 1309 / 225

Let's proceed to step 6:
When dividing 1309 by 225, we get 5 with a remainder of 184.
The number 5 becomes the next digit in our result. 
Result so far: 3635.0
If we take 1125 away from 1309, we end up with 184.
Fetch the next digit (3) from the dividend, attach it to 184 and continue: 1843 / 225

Let's proceed to step 7:
The number 225 fits into 1843 8 times, leaving a remainder of 43.
Record the quotient 8 as the next digit in the result. 
Result so far: 36358.0
Subtract 1800 from 1843 to get 43.
Grab the next digit (2) from the dividend, add it to 43, then carry on: 432 / 225

Going ahead to step 8:
When dividing 432 by 225, we get 1 with a remainder of 207.
The next digit of our result is 1. 
Result so far: 363581.0
The remainder is 207 after subtracting 225 from 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

Advancing to step 9:
The number 225 fits into 2070 9 times, leaving a remainder of 45.
Record the quotient 9 as the next digit in the result. 
Result so far: 363581.9
Deduct 2025 from 2070 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 10:
When dividing 450 by 225, we get 2 with a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 363581.92
If we subtract 450 from 450, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 11:
225 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 363581.92
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 12:
If we divide 0 by 225, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 363581.92
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 363581.92, and the remainder is 0.0.
