45012939 ÷ 452 
Our goal is to divide 45012939 by 452.

Advancing to step 1:
452 goes into 4 0 times with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 452

Let's proceed to step 2:
When dividing 45 by 452, we get 0 with a remainder of 45.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 45 leaves us with 45.
Append the next digit (0) from the dividend to 45 and continue with: 450 / 452

On to step 3:
If we divide 450 by 452, we get 0 and a remainder of 450.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 450 after subtracting 0 from 450.
Grab the next digit (1) from the dividend, add it to 450, then carry on: 4501 / 452

On to step 4:
452 goes into 4501 9 times with a remainder of 433.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtracting 4068 from 4501 leaves us with 433.
Append the next digit (2) from the dividend to 433 and continue with: 4332 / 452

Let's proceed to step 5:
If we divide 4332 by 452, we get 9 and a remainder of 264.
Use 9 as the next digit of our solution. 
Result so far: 99.0
Deduct 4068 from 4332 and we're left with 264.
Bring next digit (9) of the dividend behind the 264 and repeat the process: 2649 / 452

Step 6:
When dividing 2649 by 452, we get 5 with a remainder of 389.
Write down 5 as next digit of the result. 
Result so far: 995.0
If we take 2260 away from 2649, we end up with 389.
Grab the next digit (3) from the dividend, add it to 389, then carry on: 3893 / 452

Advancing to step 7:
452 goes into 3893 8 times with a remainder of 277.
The next digit of our result is 8. 
Result so far: 9958.0
Deduct 3616 from 3893 and we're left with 277.
Fetch the next digit (9) from the dividend, attach it to 277 and continue: 2779 / 452

Moving on to step 8:
452 goes into 2779 6 times with a remainder of 67.
The next digit of our result is 6. 
Result so far: 99586.0
The remainder is 67 after subtracting 2712 from 2779.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Advancing to step 9:
When dividing 670 by 452, we get 1 with a remainder of 218.
Use 1 as the next digit of our solution. 
Result so far: 99586.1
If we subtract 452 from 670, we get 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Let's proceed to step 10:
452 can be fit into 2180 4 times, resulting in a remainder of 372.
The number 4 becomes the next digit in our result. 
Result so far: 99586.14
Deduct 1808 from 2180 and we're left with 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

On to step 11:
452 can be fit into 3720 8 times, resulting in a remainder of 104.
Record the quotient 8 as the next digit in the result. 
Result so far: 99586.148
If we take 3616 away from 3720, we end up with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Advancing to step 12:
The number 452 fits into 1040 2 times, leaving a remainder of 136.
Put 2 as the next digit of the answer. 
Result so far: 99586.1482
Subtract 904 from 1040 to get 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Moving on to step 13:
The number 452 fits into 1360 3 times, leaving a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 99586.14823
If we subtract 1356 from 1360, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 14:
452 goes into 40 0 times with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 99586.14823
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 15:
The number 452 fits into 400 0 times, leaving a remainder of 400.
Use 0 as the next digit of our solution. 
Result so far: 99586.14823
If we take 0 away from 400, we end up with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

The final result is 99586.14823 with a remainder of 4e-06.
