If we divide 8 by 838, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 838

Going ahead to step 2:
When dividing 81 by 838, we get 0 with a remainder of 81.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 81 and we're left with 81.
Append the next digit (1) from the dividend to 81 and continue with: 811 / 838

Moving on to step 3:
If we divide 811 by 838, we get 0 and a remainder of 811.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 811, we get 811.
Fetch the next digit (4) from the dividend, attach it to 811 and continue: 8114 / 838

Moving on to step 4:
8114 divided by 838 is 9 with a remainder of 572.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtracting 7542 from 8114 leaves us with 572.
Append the next digit (7) from the dividend to 572 and continue with: 5727 / 838

Advancing to step 5:
When dividing 5727 by 838, we get 6 with a remainder of 699.
Write down 6 as next digit of the result. 
Result so far: 96.0
Subtracting 5028 from 5727 leaves us with 699.
Append the next digit (4) from the dividend to 699 and continue with: 6994 / 838

Let's proceed to step 6:
6994 divided by 838 is 8 with a remainder of 290.
Write down 8 as next digit of the result. 
Result so far: 968.0
Subtract 6704 from 6994 to get 290.
Grab the next digit (0) from the dividend, add it to 290, then carry on: 2900 / 838

Moving on to step 7:
When dividing 2900 by 838, we get 3 with a remainder of 386.
Record the quotient 3 as the next digit in the result. 
Result so far: 9683.0
Subtract 2514 from 2900 to get 386.
Include the next digit (1) from the dividend after 386, then repeat: 3861 / 838

Step 8:
If we divide 3861 by 838, we get 4 and a remainder of 509.
Write down 4 as next digit of the result. 
Result so far: 96834.0
Deduct 3352 from 3861 and we're left with 509.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5090, and continue the process.

Moving on to step 9:
838 can be fit into 5090 6 times, resulting in a remainder of 62.
The next digit of our result is 6. 
Result so far: 96834.6
If we subtract 5028 from 5090, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Step 10:
When dividing 620 by 838, we get 0 with a remainder of 620.
Use 0 as the next digit of our solution. 
Result so far: 96834.6
If we subtract 0 from 620, we get 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Advancing to step 11:
The number 838 fits into 6200 7 times, leaving a remainder of 334.
Put 7 as the next digit of the answer. 
Result so far: 96834.607
If we take 5866 away from 6200, we end up with 334.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

Let's proceed to step 12:
838 can be fit into 3340 3 times, resulting in a remainder of 826.
Put 3 as the next digit of the answer. 
Result so far: 96834.6073
Subtracting 2514 from 3340 leaves us with 826.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8260, and continue the process.

Going ahead to step 13:
The number 838 fits into 8260 9 times, leaving a remainder of 718.
The number 9 becomes the next digit in our result. 
Result so far: 96834.60739
Deduct 7542 from 8260 and we're left with 718.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7180, and continue the process.

Step 14:
If we divide 7180 by 838, we get 8 and a remainder of 476.
Write down 8 as next digit of the result. 
Result so far: 96834.607398
Deduct 6704 from 7180 and we're left with 476.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

Let's proceed to step 15:
4760 divided by 838 is 5 with a remainder of 570.
Use 5 as the next digit of our solution. 
Result so far: 96834.6073985
Subtract 4190 from 4760 to get 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5700, and continue the process.

Advancing to step 16:
The number 838 fits into 5700 6 times, leaving a remainder of 672.
Write down 6 as next digit of the result. 
Result so far: 96834.60739856
Subtract 5028 from 5700 to get 672.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6720, and continue the process.

The final outcome is 96834.60739856, with a leftover of 6.72e-07.
