We look at the division of 80686508 by 398 
We're looking to find how many times 398 goes into 80686508.

Moving on to step 1:
When dividing 8 by 398, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 398

On to step 2:
If we divide 80 by 398, we get 0 and a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 80 and we're left with 80.
Grab the next digit (6) from the dividend, add it to 80, then carry on: 806 / 398

Advancing to step 3:
806 divided by 398 is 2 with a remainder of 10.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 796 from 806 leaves us with 10.
Bring next digit (8) of the dividend behind the 10 and repeat the process: 108 / 398

Advancing to step 4:
The number 398 fits into 108 0 times, leaving a remainder of 108.
Put 0 as the next digit of the answer. 
Result so far: 20.0
The remainder is 108 after subtracting 0 from 108.
Bring next digit (6) of the dividend behind the 108 and repeat the process: 1086 / 398

Advancing to step 5:
The number 398 fits into 1086 2 times, leaving a remainder of 290.
Write down 2 as next digit of the result. 
Result so far: 202.0
If we take 796 away from 1086, we end up with 290.
Bring next digit (5) of the dividend behind the 290 and repeat the process: 2905 / 398

On to step 6:
The number 398 fits into 2905 7 times, leaving a remainder of 119.
The number 7 becomes the next digit in our result. 
Result so far: 2027.0
If we subtract 2786 from 2905, we get 119.
Append the next digit (0) from the dividend to 119 and continue with: 1190 / 398

Going ahead to step 7:
398 can be fit into 1190 2 times, resulting in a remainder of 394.
Write down 2 as next digit of the result. 
Result so far: 20272.0
Subtract 796 from 1190 to get 394.
Bring next digit (8) of the dividend behind the 394 and repeat the process: 3948 / 398

Going ahead to step 8:
3948 divided by 398 is 9 with a remainder of 366.
Write down 9 as next digit of the result. 
Result so far: 202729.0
The remainder is 366 after subtracting 3582 from 3948.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

Moving on to step 9:
3660 divided by 398 is 9 with a remainder of 78.
Put 9 as the next digit of the answer. 
Result so far: 202729.9
Subtracting 3582 from 3660 leaves us with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

On to step 10:
When dividing 780 by 398, we get 1 with a remainder of 382.
Use 1 as the next digit of our solution. 
Result so far: 202729.91
Subtracting 398 from 780 leaves us with 382.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3820, and continue the process.

Moving on to step 11:
When dividing 3820 by 398, we get 9 with a remainder of 238.
Record the quotient 9 as the next digit in the result. 
Result so far: 202729.919
Deduct 3582 from 3820 and we're left with 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Step 12:
398 can be fit into 2380 5 times, resulting in a remainder of 390.
Use 5 as the next digit of our solution. 
Result so far: 202729.9195
Subtracting 1990 from 2380 leaves us with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Moving on to step 13:
The number 398 fits into 3900 9 times, leaving a remainder of 318.
The next digit of our result is 9. 
Result so far: 202729.91959
Subtract 3582 from 3900 to get 318.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

Advancing to step 14:
398 can be fit into 3180 7 times, resulting in a remainder of 394.
Write down 7 as next digit of the result. 
Result so far: 202729.919597
The remainder is 394 after subtracting 2786 from 3180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

Let's proceed to step 15:
The number 398 fits into 3940 9 times, leaving a remainder of 358.
The number 9 becomes the next digit in our result. 
Result so far: 202729.9195979
The remainder is 358 after subtracting 3582 from 3940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

Moving on to step 16:
3580 divided by 398 is 8 with a remainder of 396.
The number 8 becomes the next digit in our result. 
Result so far: 202729.91959798
If we subtract 3184 from 3580, we get 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

In conclusion, the division gives 202729.91959798 with a balance of 3.96e-07.
