We look at the division of 20178853 by 457 
We want to figure out the number of times 20178853 can be divided by 457.

Let's proceed to step 1:
457 can be fit into 2 0 times, resulting in a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 457

Going ahead to step 2:
The number 457 fits into 20 0 times, leaving a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 20, we get 20.
Bring next digit (1) of the dividend behind the 20 and repeat the process: 201 / 457

Moving on to step 3:
457 can be fit into 201 0 times, resulting in a remainder of 201.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 201 after subtracting 0 from 201.
Append the next digit (7) from the dividend to 201 and continue with: 2017 / 457

On to step 4:
457 goes into 2017 4 times with a remainder of 189.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtract 1828 from 2017 to get 189.
Bring next digit (8) of the dividend behind the 189 and repeat the process: 1898 / 457

On to step 5:
When dividing 1898 by 457, we get 4 with a remainder of 70.
Use 4 as the next digit of our solution. 
Result so far: 44.0
If we subtract 1828 from 1898, we get 70.
Take the next digit (8) from the dividend and append it to 70, then repeat: 708 / 457

Going ahead to step 6:
The number 457 fits into 708 1 times, leaving a remainder of 251.
Record the quotient 1 as the next digit in the result. 
Result so far: 441.0
Deduct 457 from 708 and we're left with 251.
Fetch the next digit (5) from the dividend, attach it to 251 and continue: 2515 / 457

Going ahead to step 7:
457 can be fit into 2515 5 times, resulting in a remainder of 230.
Record the quotient 5 as the next digit in the result. 
Result so far: 4415.0
Subtracting 2285 from 2515 leaves us with 230.
Fetch the next digit (3) from the dividend, attach it to 230 and continue: 2303 / 457

Advancing to step 8:
457 goes into 2303 5 times with a remainder of 18.
Write down 5 as next digit of the result. 
Result so far: 44155.0
Subtract 2285 from 2303 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 9:
When dividing 180 by 457, we get 0 with a remainder of 180.
Use 0 as the next digit of our solution. 
Result so far: 44155.0
Subtracting 0 from 180 leaves us with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Moving on to step 10:
457 can be fit into 1800 3 times, resulting in a remainder of 429.
The next digit of our result is 3. 
Result so far: 44155.03
Subtracting 1371 from 1800 leaves us with 429.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4290, and continue the process.

Advancing to step 11:
457 can be fit into 4290 9 times, resulting in a remainder of 177.
Use 9 as the next digit of our solution. 
Result so far: 44155.039
Subtract 4113 from 4290 to get 177.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1770, and continue the process.

Step 12:
The number 457 fits into 1770 3 times, leaving a remainder of 399.
The next digit of our result is 3. 
Result so far: 44155.0393
If we take 1371 away from 1770, we end up with 399.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3990, and continue the process.

Going ahead to step 13:
457 goes into 3990 8 times with a remainder of 334.
Write down 8 as next digit of the result. 
Result so far: 44155.03938
If we subtract 3656 from 3990, we get 334.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

Moving on to step 14:
When dividing 3340 by 457, we get 7 with a remainder of 141.
Write down 7 as next digit of the result. 
Result so far: 44155.039387
Deduct 3199 from 3340 and we're left with 141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

Moving on to step 15:
457 can be fit into 1410 3 times, resulting in a remainder of 39.
The next digit of our result is 3. 
Result so far: 44155.0393873
The remainder is 39 after subtracting 1371 from 1410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 16:
457 goes into 390 0 times with a remainder of 390.
Put 0 as the next digit of the answer. 
Result so far: 44155.0393873
Subtracting 0 from 390 leaves us with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

The final result is 44155.0393873 with a remainder of 3.9e-07.
