We're dividing 20345138 by 452 
Let's see how many times 452 fits into 20345138.

Moving on to step 1:
The number 452 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 452

Going ahead to step 2:
452 goes into 20 0 times with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 20 leaves us with 20.
Bring next digit (3) of the dividend behind the 20 and repeat the process: 203 / 452

Advancing to step 3:
When dividing 203 by 452, we get 0 with a remainder of 203.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 203 to get 203.
Fetch the next digit (4) from the dividend, attach it to 203 and continue: 2034 / 452

On to step 4:
The number 452 fits into 2034 4 times, leaving a remainder of 226.
The next digit of our result is 4. 
Result so far: 4.0
If we subtract 1808 from 2034, we get 226.
Fetch the next digit (5) from the dividend, attach it to 226 and continue: 2265 / 452

Advancing to step 5:
When dividing 2265 by 452, we get 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 45.0
If we subtract 2260 from 2265, we get 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 452

Let's proceed to step 6:
452 can be fit into 51 0 times, resulting in a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 450.0
Subtract 0 from 51 to get 51.
Take the next digit (3) from the dividend and append it to 51, then repeat: 513 / 452

Advancing to step 7:
The number 452 fits into 513 1 times, leaving a remainder of 61.
Record the quotient 1 as the next digit in the result. 
Result so far: 4501.0
Deduct 452 from 513 and we're left with 61.
Append the next digit (8) from the dividend to 61 and continue with: 618 / 452

Let's proceed to step 8:
452 goes into 618 1 times with a remainder of 166.
Record the quotient 1 as the next digit in the result. 
Result so far: 45011.0
Subtracting 452 from 618 leaves us with 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Going ahead to step 9:
1660 divided by 452 is 3 with a remainder of 304.
The next digit of our result is 3. 
Result so far: 45011.3
Subtract 1356 from 1660 to get 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Step 10:
If we divide 3040 by 452, we get 6 and a remainder of 328.
Put 6 as the next digit of the answer. 
Result so far: 45011.36
If we subtract 2712 from 3040, we get 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

On to step 11:
3280 divided by 452 is 7 with a remainder of 116.
The next digit of our result is 7. 
Result so far: 45011.367
If we subtract 3164 from 3280, we get 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Moving on to step 12:
The number 452 fits into 1160 2 times, leaving a remainder of 256.
Use 2 as the next digit of our solution. 
Result so far: 45011.3672
The remainder is 256 after subtracting 904 from 1160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Step 13:
452 can be fit into 2560 5 times, resulting in a remainder of 300.
The number 5 becomes the next digit in our result. 
Result so far: 45011.36725
Deduct 2260 from 2560 and we're left with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Moving on to step 14:
If we divide 3000 by 452, we get 6 and a remainder of 288.
Use 6 as the next digit of our solution. 
Result so far: 45011.367256
The remainder is 288 after subtracting 2712 from 3000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

On to step 15:
When dividing 2880 by 452, we get 6 with a remainder of 168.
Use 6 as the next digit of our solution. 
Result so far: 45011.3672566
Deduct 2712 from 2880 and we're left with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

In conclusion, the division gives 45011.3672566 with a balance of 1.68e-06.
