81402836 divided by 225 
We're looking to find how many times 225 goes into 81402836.

Advancing to step 1:
225 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 225

Advancing to step 2:
When dividing 81 by 225, we get 0 with a remainder of 81.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 81 and we're left with 81.
Grab the next digit (4) from the dividend, add it to 81, then carry on: 814 / 225

Advancing to step 3:
225 can be fit into 814 3 times, resulting in a remainder of 139.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we subtract 675 from 814, we get 139.
Fetch the next digit (0) from the dividend, attach it to 139 and continue: 1390 / 225

Step 4:
225 goes into 1390 6 times with a remainder of 40.
Record the quotient 6 as the next digit in the result. 
Result so far: 36.0
Subtracting 1350 from 1390 leaves us with 40.
Take the next digit (2) from the dividend and append it to 40, then repeat: 402 / 225

Going ahead to step 5:
402 divided by 225 is 1 with a remainder of 177.
The number 1 becomes the next digit in our result. 
Result so far: 361.0
Deduct 225 from 402 and we're left with 177.
Bring next digit (8) of the dividend behind the 177 and repeat the process: 1778 / 225

Advancing to step 6:
1778 divided by 225 is 7 with a remainder of 203.
Write down 7 as next digit of the result. 
Result so far: 3617.0
Deduct 1575 from 1778 and we're left with 203.
Grab the next digit (3) from the dividend, add it to 203, then carry on: 2033 / 225

On to step 7:
225 can be fit into 2033 9 times, resulting in a remainder of 8.
The number 9 becomes the next digit in our result. 
Result so far: 36179.0
Subtracting 2025 from 2033 leaves us with 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 225

Let's proceed to step 8:
The number 225 fits into 86 0 times, leaving a remainder of 86.
The next digit of our result is 0. 
Result so far: 361790.0
If we subtract 0 from 86, we get 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Step 9:
When dividing 860 by 225, we get 3 with a remainder of 185.
Put 3 as the next digit of the answer. 
Result so far: 361790.3
Subtract 675 from 860 to get 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Step 10:
225 can be fit into 1850 8 times, resulting in a remainder of 50.
Record the quotient 8 as the next digit in the result. 
Result so far: 361790.38
Subtracting 1800 from 1850 leaves us 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.

Advancing to step 11:
The number 225 fits into 500 2 times, leaving a remainder of 50.
The next digit of our result is 2. 
Result so far: 361790.382
If we subtract 450 from 500, we 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.

Let's proceed to step 12:
225 goes into 500 2 times with a remainder of 50.
The next digit of our result is 2. 
Result so far: 361790.3822
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.

After the division, we end up with 361790.3822 and a remainder of 0.0005.
