We look at the division of 17877387 by 838 
We're looking to find how many times 838 goes into 17877387.

Going ahead to step 1:
838 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 838

Step 2:
If we divide 17 by 838, we get 0 and a remainder of 17.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 17 after subtracting 0 from 17.
Fetch the next digit (8) from the dividend, attach it to 17 and continue: 178 / 838

Advancing to step 3:
If we divide 178 by 838, we get 0 and a remainder of 178.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 178 to get 178.
Grab the next digit (7) from the dividend, add it to 178, then carry on: 1787 / 838

On to step 4:
1787 divided by 838 is 2 with a remainder of 111.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 1676 from 1787 to get 111.
Take the next digit (7) from the dividend and append it to 111, then repeat: 1117 / 838

Going ahead to step 5:
1117 divided by 838 is 1 with a remainder of 279.
Write down 1 as next digit of the result. 
Result so far: 21.0
If we subtract 838 from 1117, we get 279.
Fetch the next digit (3) from the dividend, attach it to 279 and continue: 2793 / 838

Advancing to step 6:
The number 838 fits into 2793 3 times, leaving a remainder of 279.
The next digit of our result is 3. 
Result so far: 213.0
The remainder is 279 after subtracting 2514 from 2793.
Bring next digit (8) of the dividend behind the 279 and repeat the process: 2798 / 838

Moving on to step 7:
When dividing 2798 by 838, we get 3 with a remainder of 284.
Use 3 as the next digit of our solution. 
Result so far: 2133.0
Subtract 2514 from 2798 to get 284.
Include the next digit (7) from the dividend after 284, then repeat: 2847 / 838

Let's proceed to step 8:
If we divide 2847 by 838, we get 3 and a remainder of 333.
Record the quotient 3 as the next digit in the result. 
Result so far: 21333.0
If we take 2514 away from 2847, we end up with 333.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3330, and continue the process.

Moving on to step 9:
3330 divided by 838 is 3 with a remainder of 816.
Use 3 as the next digit of our solution. 
Result so far: 21333.3
Deduct 2514 from 3330 and we're left with 816.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8160, and continue the process.

Let's proceed to step 10:
838 goes into 8160 9 times with a remainder of 618.
Write down 9 as next digit of the result. 
Result so far: 21333.39
If we take 7542 away from 8160, we end up with 618.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6180, and continue the process.

Moving on to step 11:
6180 divided by 838 is 7 with a remainder of 314.
The next digit of our result is 7. 
Result so far: 21333.397
If we take 5866 away from 6180, we end up with 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

On to step 12:
838 can be fit into 3140 3 times, resulting in a remainder of 626.
Put 3 as the next digit of the answer. 
Result so far: 21333.3973
If we subtract 2514 from 3140, we get 626.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6260, and continue the process.

On to step 13:
When dividing 6260 by 838, we get 7 with a remainder of 394.
Put 7 as the next digit of the answer. 
Result so far: 21333.39737
Subtracting 5866 from 6260 leaves us with 394.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

Step 14:
3940 divided by 838 is 4 with a remainder of 588.
Use 4 as the next digit of our solution. 
Result so far: 21333.397374
Deduct 3352 from 3940 and we're left with 588.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5880, and continue the process.

Let's proceed to step 15:
If we divide 5880 by 838, we get 7 and a remainder of 14.
Write down 7 as next digit of the result. 
Result so far: 21333.3973747
If we take 5866 away from 5880, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 16:
If we divide 140 by 838, we get 0 and a remainder of 140.
Write down 0 as next digit of the result. 
Result so far: 21333.3973747
Deduct 0 from 140 and we're left with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

After the division, we end up with 21333.3973747 and a remainder of 1.4e-07.
