71813521 ÷ 227 
We're looking to find how many times 227 goes into 71813521.

Going ahead to step 1:
If we divide 7 by 227, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Take the next digit (1) from the dividend and append it to 7, then repeat: 71 / 227

Let's proceed to step 2:
227 goes into 71 0 times with a remainder of 71.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 71 after subtracting 0 from 71.
Grab the next digit (8) from the dividend, add it to 71, then carry on: 718 / 227

Going ahead to step 3:
When dividing 718 by 227, we get 3 with a remainder of 37.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 681 from 718 and we're left with 37.
Grab the next digit (1) from the dividend, add it to 37, then carry on: 371 / 227

On to step 4:
227 can be fit into 371 1 times, resulting in a remainder of 144.
Use 1 as the next digit of our solution. 
Result so far: 31.0
Subtract 227 from 371 to get 144.
Bring next digit (3) of the dividend behind the 144 and repeat the process: 1443 / 227

On to step 5:
227 can be fit into 1443 6 times, resulting in a remainder of 81.
The next digit of our result is 6. 
Result so far: 316.0
If we subtract 1362 from 1443, we get 81.
Include the next digit (5) from the dividend after 81, then repeat: 815 / 227

Step 6:
When dividing 815 by 227, we get 3 with a remainder of 134.
The number 3 becomes the next digit in our result. 
Result so far: 3163.0
If we subtract 681 from 815, we get 134.
Grab the next digit (2) from the dividend, add it to 134, then carry on: 1342 / 227

Advancing to step 7:
The number 227 fits into 1342 5 times, leaving a remainder of 207.
Use 5 as the next digit of our solution. 
Result so far: 31635.0
Subtracting 1135 from 1342 leaves us with 207.
Grab the next digit (1) from the dividend, add it to 207, then carry on: 2071 / 227

Going ahead to step 8:
2071 divided by 227 is 9 with a remainder of 28.
The number 9 becomes the next digit in our result. 
Result so far: 316359.0
Subtracting 2043 from 2071 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 9:
If we divide 280 by 227, we get 1 and a remainder of 53.
Record the quotient 1 as the next digit in the result. 
Result so far: 316359.1
The remainder is 53 after subtracting 227 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Moving on to step 10:
530 divided by 227 is 2 with a remainder of 76.
Record the quotient 2 as the next digit in the result. 
Result so far: 316359.12
Deduct 454 from 530 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Let's proceed to step 11:
227 can be fit into 760 3 times, resulting in a remainder of 79.
The number 3 becomes the next digit in our result. 
Result so far: 316359.123
Deduct 681 from 760 and we're left with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Advancing to step 12:
If we divide 790 by 227, we get 3 and a remainder of 109.
Record the quotient 3 as the next digit in the result. 
Result so far: 316359.1233
If we take 681 away from 790, we end up with 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

After the division, we end up with 316359.1233 and a remainder of 0.00109.
