1720 divided by 838 is 2 with a remainder of 44.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 44 after subtracting 1676 from 1720.
Append the next digit (1) from the dividend to 44 and continue with: 441 / 838

Advancing to step 5:
441 divided by 838 is 0 with a remainder of 441.
Use 0 as the next digit of our solution. 
Result so far: 20.0
Subtract 0 from 441 to get 441.
Grab the next digit (5) from the dividend, add it to 441, then carry on: 4415 / 838

Moving on to step 6:
4415 divided by 838 is 5 with a remainder of 225.
Use 5 as the next digit of our solution. 
Result so far: 205.0
Subtracting 4190 from 4415 leaves us with 225.
Grab the next digit (1) from the dividend, add it to 225, then carry on: 2251 / 838

Moving on to step 7:
2251 divided by 838 is 2 with a remainder of 575.
Write down 2 as next digit of the result. 
Result so far: 2052.0
If we subtract 1676 from 2251, we get 575.
Append the next digit (6) from the dividend to 575 and continue with: 5756 / 838

Step 8:
If we divide 5756 by 838, we get 6 and a remainder of 728.
Write down 6 as next digit of the result. 
Result so far: 20526.0
Subtract 5028 from 5756 to get 728.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7280, and continue the process.

Advancing to step 9:
If we divide 7280 by 838, we get 8 and a remainder of 576.
Put 8 as the next digit of the answer. 
Result so far: 20526.8
Deduct 6704 from 7280 and we're left with 576.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

Going ahead to step 10:
The number 838 fits into 5760 6 times, leaving a remainder of 732.
Use 6 as the next digit of our solution. 
Result so far: 20526.86
If we take 5028 away from 5760, we end up with 732.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7320, and continue the process.

Advancing to step 11:
7320 divided by 838 is 8 with a remainder of 616.
The number 8 becomes the next digit in our result. 
Result so far: 20526.868
The remainder is 616 after subtracting 6704 from 7320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6160, and continue the process.

Moving on to step 12:
838 can be fit into 6160 7 times, resulting in a remainder of 294.
Write down 7 as next digit of the result. 
Result so far: 20526.8687
The remainder is 294 after subtracting 5866 from 6160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

Going ahead to step 13:
2940 divided by 838 is 3 with a remainder of 426.
Put 3 as the next digit of the answer. 
Result so far: 20526.86873
Subtracting 2514 from 2940 leaves us with 426.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4260, and continue the process.

Going ahead to step 14:
When dividing 4260 by 838, we get 5 with a remainder of 70.
Use 5 as the next digit of our solution. 
Result so far: 20526.868735
Subtracting 4190 from 4260 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 15:
838 goes into 700 0 times with a remainder of 700.
The next digit of our result is 0. 
Result so far: 20526.868735
If we subtract 0 from 700, we get 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Going ahead to step 16:
838 goes into 7000 8 times with a remainder of 296.
The number 8 becomes the next digit in our result. 
Result so far: 20526.86873508
Subtracting 6704 from 7000 leaves us with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

The final result is 20526.86873508 with a remainder of 2.96e-07.
