Let's divide 80151131 by 45
Let's see how many times 45 fits into 80151131.

Moving on to step 1:
When dividing 8 by 45, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 45

Going ahead to step 2:
45 goes into 80 1 times with a remainder of 35.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 45 from 80 leaves us with 35.
Include the next digit (1) from the dividend after 35, then repeat: 351 / 45

Step 3:
The number 45 fits into 351 7 times, leaving a remainder of 36.
Write down 7 as next digit of the result. 
Result so far: 17.0
Subtracting 315 from 351 leaves us with 36.
Append the next digit (5) from the dividend to 36 and continue with: 365 / 45

Going ahead to step 4:
The number 45 fits into 365 8 times, leaving a remainder of 5.
Use 8 as the next digit of our solution. 
Result so far: 178.0
Subtracting 360 from 365 leaves us with 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 45

Let's proceed to step 5:
51 divided by 45 is 1 with a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 1781.0
Subtracting 45 from 51 leaves us with 6.
Take the next digit (1) from the dividend and append it to 6, then repeat: 61 / 45

On to step 6:
If we divide 61 by 45, we get 1 and a remainder of 16.
Use 1 as the next digit of our solution. 
Result so far: 17811.0
If we take 45 away from 61, we end up with 16.
Bring next digit (3) of the dividend behind the 16 and repeat the process: 163 / 45

Step 7:
45 can be fit into 163 3 times, resulting in a remainder of 28.
Record the quotient 3 as the next digit in the result. 
Result so far: 178113.0
Subtracting 135 from 163 leaves us with 28.
Take the next digit (1) from the dividend and append it to 28, then repeat: 281 / 45

On to step 8:
The number 45 fits into 281 6 times, leaving a remainder of 11.
Use 6 as the next digit of our solution. 
Result so far: 1781136.0
If we take 270 away from 281, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 9:
If we divide 110 by 45, we get 2 and a remainder of 20.
Put 2 as the next digit of the answer. 
Result so far: 1781136.2
Deduct 90 from 110 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 10:
200 divided by 45 is 4 with a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 1781136.24
Subtract 180 from 200 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 11:
When dividing 200 by 45, we get 4 with a remainder of 20.
Record the quotient 4 as the next digit in the result. 
Result so far: 1781136.244
Deduct 180 from 200 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The quotient of the division is 1781136.244, and the remainder is 0.002.
