We're dividing 20100400 by 718 
We're looking to find how many times 718 goes into 20100400.

Step 1:
718 can be fit into 2 0 times, resulting in a remainder of 2.
The number 0 becomes the next digit in our 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 / 718

Let's proceed to step 2:
When dividing 20 by 718, we get 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 20 after subtracting 0 from 20.
Fetch the next digit (1) from the dividend, attach it to 20 and continue: 201 / 718

On to step 3:
When dividing 201 by 718, we get 0 with a remainder of 201.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 201 to get 201.
Bring next digit (0) of the dividend behind the 201 and repeat the process: 2010 / 718

Step 4:
718 can be fit into 2010 2 times, resulting in a remainder of 574.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 1436 from 2010 and we're left with 574.
Include the next digit (0) from the dividend after 574, then repeat: 5740 / 718

Moving on to step 5:
718 goes into 5740 7 times with a remainder of 714.
Write down 7 as next digit of the result. 
Result so far: 27.0
Subtracting 5026 from 5740 leaves us with 714.
Grab the next digit (4) from the dividend, add it to 714, then carry on: 7144 / 718

Advancing to step 6:
7144 divided by 718 is 9 with a remainder of 682.
Write down 9 as next digit of the result. 
Result so far: 279.0
The remainder is 682 after subtracting 6462 from 7144.
Grab the next digit (0) from the dividend, add it to 682, then carry on: 6820 / 718

Moving on to step 7:
The number 718 fits into 6820 9 times, leaving a remainder of 358.
The next digit of our result is 9. 
Result so far: 2799.0
The remainder is 358 after subtracting 6462 from 6820.
Bring next digit (0) of the dividend behind the 358 and repeat the process: 3580 / 718

On to step 8:
718 goes into 3580 4 times with a remainder of 708.
The next digit of our result is 4. 
Result so far: 27994.0
If we subtract 2872 from 3580, we get 708.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7080, and continue the process.

Going ahead to step 9:
718 goes into 7080 9 times with a remainder of 618.
Put 9 as the next digit of the answer. 
Result so far: 27994.9
If we subtract 6462 from 7080, we get 618.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6180, and continue the process.

Let's proceed to step 10:
718 goes into 6180 8 times with a remainder of 436.
The next digit of our result is 8. 
Result so far: 27994.98
Subtracting 5744 from 6180 leaves us with 436.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4360, and continue the process.

Advancing to step 11:
When dividing 4360 by 718, we get 6 with a remainder of 52.
Use 6 as the next digit of our solution. 
Result so far: 27994.986
If we take 4308 away from 4360, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 12:
718 can be fit into 520 0 times, resulting in a remainder of 520.
Put 0 as the next digit of the answer. 
Result so far: 27994.986
Subtracting 0 from 520 leaves us with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Moving on to step 13:
When dividing 5200 by 718, we get 7 with a remainder of 174.
Put 7 as the next digit of the answer. 
Result so far: 27994.98607
If we subtract 5026 from 5200, we get 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Advancing to step 14:
When dividing 1740 by 718, we get 2 with a remainder of 304.
Use 2 as the next digit of our solution. 
Result so far: 27994.986072
Subtracting 1436 from 1740 leaves us with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Let's proceed to step 15:
When dividing 3040 by 718, we get 4 with a remainder of 168.
The next digit of our result is 4. 
Result so far: 27994.9860724
If we subtract 2872 from 3040, we get 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Advancing to step 16:
718 goes into 1680 2 times with a remainder of 244.
The number 2 becomes the next digit in our result. 
Result so far: 27994.98607242
Deduct 1436 from 1680 and we're left with 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

The final outcome is 27994.98607242, with a leftover of 2.44e-07.
