Result so far: 28.0
If we subtract 6704 from 7137, we get 433.
Append the next digit (6) from the dividend to 433 and continue with: 4336 / 838

On to step 6:
838 goes into 4336 5 times with a remainder of 146.
Put 5 as the next digit of the answer. 
Result so far: 285.0
If we take 4190 away from 4336, we end up with 146.
Grab the next digit (5) from the dividend, add it to 146, then carry on: 1465 / 838

Moving on to step 7:
838 can be fit into 1465 1 times, resulting in a remainder of 627.
Write down 1 as next digit of the result. 
Result so far: 2851.0
Subtracting 838 from 1465 leaves us with 627.
Append the next digit (4) from the dividend to 627 and continue with: 6274 / 838

On to step 8:
838 goes into 6274 7 times with a remainder of 408.
Use 7 as the next digit of our solution. 
Result so far: 28517.0
Subtracting 5866 from 6274 leaves us with 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Going ahead to step 9:
838 can be fit into 4080 4 times, resulting in a remainder of 728.
Record the quotient 4 as the next digit in the result. 
Result so far: 28517.4
The remainder is 728 after subtracting 3352 from 4080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7280, and continue the process.

Step 10:
The number 838 fits into 7280 8 times, leaving a remainder of 576.
Use 8 as the next digit of our solution. 
Result so far: 28517.48
The remainder is 576 after subtracting 6704 from 7280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

Advancing to step 11:
838 can be fit into 5760 6 times, resulting in a remainder of 732.
Use 6 as the next digit of our solution. 
Result so far: 28517.486
Subtracting 5028 from 5760 leaves us 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.

Let's proceed to step 12:
The number 838 fits into 7320 8 times, leaving a remainder of 616.
Record the quotient 8 as the next digit in the result. 
Result so far: 28517.4868
Subtracting 6704 from 7320 leaves us with 616.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6160, and continue the process.

Let's proceed to step 13:
The number 838 fits into 6160 7 times, leaving a remainder of 294.
The next digit of our result is 7. 
Result so far: 28517.48687
If we subtract 5866 from 6160, we get 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

On to step 14:
When dividing 2940 by 838, we get 3 with a remainder of 426.
Put 3 as the next digit of the answer. 
Result so far: 28517.486873
Deduct 2514 from 2940 and we're left 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.

Moving on to step 15:
838 goes into 4260 5 times with a remainder of 70.
Use 5 as the next digit of our solution. 
Result so far: 28517.4868735
The remainder is 70 after subtracting 4190 from 4260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 16:
838 goes into 700 0 times with a remainder of 700.
Put 0 as the next digit of the answer. 
Result so far: 28517.4868735
The remainder is 700 after subtracting 0 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

The quotient of the division is 28517.4868735, and the remainder is 7e-07.
