20447720 ÷ 452 
We want to divide 20447720 by 452.

Step 1:
452 can be fit into 2 0 times, resulting in a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 452

Going ahead to step 2:
If we divide 20 by 452, we get 0 and a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 20, we end up with 20.
Take the next digit (4) from the dividend and append it to 20, then repeat: 204 / 452

Moving on to step 3:
The number 452 fits into 204 0 times, leaving a remainder of 204.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 204, we get 204.
Bring next digit (4) of the dividend behind the 204 and repeat the process: 2044 / 452

Let's proceed to step 4:
The number 452 fits into 2044 4 times, leaving a remainder of 236.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtract 1808 from 2044 to get 236.
Bring next digit (7) of the dividend behind the 236 and repeat the process: 2367 / 452

On to step 5:
The number 452 fits into 2367 5 times, leaving a remainder of 107.
Put 5 as the next digit of the answer. 
Result so far: 45.0
If we subtract 2260 from 2367, we get 107.
Take the next digit (7) from the dividend and append it to 107, then repeat: 1077 / 452

Going ahead to step 6:
1077 divided by 452 is 2 with a remainder of 173.
Record the quotient 2 as the next digit in the result. 
Result so far: 452.0
Subtract 904 from 1077 to get 173.
Bring next digit (2) of the dividend behind the 173 and repeat the process: 1732 / 452

Moving on to step 7:
The number 452 fits into 1732 3 times, leaving a remainder of 376.
The number 3 becomes the next digit in our result. 
Result so far: 4523.0
The remainder is 376 after subtracting 1356 from 1732.
Include the next digit (0) from the dividend after 376, then repeat: 3760 / 452

Going ahead to step 8:
When dividing 3760 by 452, we get 8 with a remainder of 144.
Use 8 as the next digit of our solution. 
Result so far: 45238.0
If we take 3616 away from 3760, we end up with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Let's proceed to step 9:
The number 452 fits into 1440 3 times, leaving a remainder of 84.
The next digit of our result is 3. 
Result so far: 45238.3
If we subtract 1356 from 1440, we get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Step 10:
When dividing 840 by 452, we get 1 with a remainder of 388.
Write down 1 as next digit of the result. 
Result so far: 45238.31
Deduct 452 from 840 and we're left with 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Moving on to step 11:
The number 452 fits into 3880 8 times, leaving a remainder of 264.
The number 8 becomes the next digit in our result. 
Result so far: 45238.318
The remainder is 264 after subtracting 3616 from 3880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Let's proceed to step 12:
452 can be fit into 2640 5 times, resulting in a remainder of 380.
The number 5 becomes the next digit in our result. 
Result so far: 45238.3185
If we subtract 2260 from 2640, we get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Advancing to step 13:
452 can be fit into 3800 8 times, resulting in a remainder of 184.
The number 8 becomes the next digit in our result. 
Result so far: 45238.31858
Subtract 3616 from 3800 to get 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Step 14:
452 can be fit into 1840 4 times, resulting in a remainder of 32.
Record the quotient 4 as the next digit in the result. 
Result so far: 45238.318584
The remainder is 32 after subtracting 1808 from 1840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 15:
320 divided by 452 is 0 with a remainder of 320.
Put 0 as the next digit of the answer. 
Result so far: 45238.318584
Subtracting 0 from 320 leaves us with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Going ahead to step 16:
3200 divided by 452 is 7 with a remainder of 36.
The next digit of our result is 7. 
Result so far: 45238.31858407
Deduct 3164 from 3200 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

The quotient of the division is 45238.31858407, and the remainder is 3.6e-08.
