We're dividing 20177290 by 658 
We want to figure out the number of times 20177290 can be divided by 658.

On to step 1:
When dividing 2 by 658, we get 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 658

Let's proceed to step 2:
658 goes into 20 0 times with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 20 to get 20.
Bring next digit (1) of the dividend behind the 20 and repeat the process: 201 / 658

Moving on to step 3:
The number 658 fits into 201 0 times, leaving a remainder of 201.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 201, we get 201.
Append the next digit (7) from the dividend to 201 and continue with: 2017 / 658

Moving on to step 4:
658 goes into 2017 3 times with a remainder of 43.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 1974 away from 2017, we end up with 43.
Grab the next digit (7) from the dividend, add it to 43, then carry on: 437 / 658

Going ahead to step 5:
437 divided by 658 is 0 with a remainder of 437.
Write down 0 as next digit of the result. 
Result so far: 30.0
If we take 0 away from 437, we end up with 437.
Take the next digit (2) from the dividend and append it to 437, then repeat: 4372 / 658

Advancing to step 6:
The number 658 fits into 4372 6 times, leaving a remainder of 424.
The number 6 becomes the next digit in our result. 
Result so far: 306.0
Subtracting 3948 from 4372 leaves us with 424.
Include the next digit (9) from the dividend after 424, then repeat: 4249 / 658

Going ahead to step 7:
658 can be fit into 4249 6 times, resulting in a remainder of 301.
Put 6 as the next digit of the answer. 
Result so far: 3066.0
Subtracting 3948 from 4249 leaves us with 301.
Append the next digit (0) from the dividend to 301 and continue with: 3010 / 658

On to step 8:
3010 divided by 658 is 4 with a remainder of 378.
Put 4 as the next digit of the answer. 
Result so far: 30664.0
Deduct 2632 from 3010 and we're left with 378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

Advancing to step 9:
If we divide 3780 by 658, we get 5 and a remainder of 490.
The number 5 becomes the next digit in our result. 
Result so far: 30664.5
The remainder is 490 after subtracting 3290 from 3780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Let's proceed to step 10:
If we divide 4900 by 658, we get 7 and a remainder of 294.
Use 7 as the next digit of our solution. 
Result so far: 30664.57
Subtracting 4606 from 4900 leaves us with 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

Step 11:
658 goes into 2940 4 times with a remainder of 308.
The number 4 becomes the next digit in our result. 
Result so far: 30664.574
If we subtract 2632 from 2940, we get 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Let's proceed to step 12:
658 goes into 3080 4 times with a remainder of 448.
The next digit of our result is 4. 
Result so far: 30664.5744
Subtracting 2632 from 3080 leaves us with 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

After the division, we end up with 30664.5744 and a remainder of 0.00448.
