71222241 divided by 45 
Let's see how many times 45 fits into 71222241.

On to step 1:
If we divide 7 by 45, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (1) from the dividend, attach it to 7 and continue: 71 / 45

Moving on to step 2:
45 can be fit into 71 1 times, resulting in a remainder of 26.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 45 from 71 leaves us with 26.
Fetch the next digit (2) from the dividend, attach it to 26 and continue: 262 / 45

On to step 3:
If we divide 262 by 45, we get 5 and a remainder of 37.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
If we take 225 away from 262, we end up with 37.
Take the next digit (2) from the dividend and append it to 37, then repeat: 372 / 45

Advancing to step 4:
When dividing 372 by 45, we get 8 with a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 158.0
If we take 360 away from 372, we end up with 12.
Take the next digit (2) from the dividend and append it to 12, then repeat: 122 / 45

Let's proceed to step 5:
45 can be fit into 122 2 times, resulting in a remainder of 32.
The next digit of our result is 2. 
Result so far: 1582.0
If we subtract 90 from 122, we get 32.
Take the next digit (2) from the dividend and append it to 32, then repeat: 322 / 45

Let's proceed to step 6:
45 can be fit into 322 7 times, resulting in a remainder of 7.
The number 7 becomes the next digit in our result. 
Result so far: 15827.0
Subtracting 315 from 322 leaves us with 7.
Bring next digit (4) of the dividend behind the 7 and repeat the process: 74 / 45

On to step 7:
If we divide 74 by 45, we get 1 and a remainder of 29.
Write down 1 as next digit of the result. 
Result so far: 158271.0
Deduct 45 from 74 and we're left with 29.
Grab the next digit (1) from the dividend, add it to 29, then carry on: 291 / 45

Step 8:
45 can be fit into 291 6 times, resulting in a remainder of 21.
Put 6 as the next digit of the answer. 
Result so far: 1582716.0
Deduct 270 from 291 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 9:
If we divide 210 by 45, we get 4 and a remainder of 30.
The number 4 becomes the next digit in our result. 
Result so far: 1582716.4
If we subtract 180 from 210, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 10:
If we divide 300 by 45, we get 6 and a remainder of 30.
The number 6 becomes the next digit in our result. 
Result so far: 1582716.46
Deduct 270 from 300 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 11:
When dividing 300 by 45, we get 6 with a remainder of 30.
Put 6 as the next digit of the answer. 
Result so far: 1582716.466
Subtract 270 from 300 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The final result is 1582716.466 with a remainder of 0.003.
