98691258 ÷ 397 
Our goal is to divide 98691258 by 397.

Let's proceed to step 1:
The number 397 fits into 9 0 times, leaving a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Bring next digit (8) of the dividend behind the 9 and repeat the process: 98 / 397

Moving on to step 2:
If we divide 98 by 397, we get 0 and a remainder of 98.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 98 and we're left with 98.
Append the next digit (6) from the dividend to 98 and continue with: 986 / 397

On to step 3:
The number 397 fits into 986 2 times, leaving a remainder of 192.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 192 after subtracting 794 from 986.
Append the next digit (9) from the dividend to 192 and continue with: 1929 / 397

Step 4:
When dividing 1929 by 397, we get 4 with a remainder of 341.
The next digit of our result is 4. 
Result so far: 24.0
If we take 1588 away from 1929, we end up with 341.
Bring next digit (1) of the dividend behind the 341 and repeat the process: 3411 / 397

Step 5:
When dividing 3411 by 397, we get 8 with a remainder of 235.
The next digit of our result is 8. 
Result so far: 248.0
If we subtract 3176 from 3411, we get 235.
Append the next digit (2) from the dividend to 235 and continue with: 2352 / 397

On to step 6:
2352 divided by 397 is 5 with a remainder of 367.
The number 5 becomes the next digit in our result. 
Result so far: 2485.0
Deduct 1985 from 2352 and we're left with 367.
Take the next digit (5) from the dividend and append it to 367, then repeat: 3675 / 397

Step 7:
397 goes into 3675 9 times with a remainder of 102.
Write down 9 as next digit of the result. 
Result so far: 24859.0
The remainder is 102 after subtracting 3573 from 3675.
Bring next digit (8) of the dividend behind the 102 and repeat the process: 1028 / 397

On to step 8:
1028 divided by 397 is 2 with a remainder of 234.
Put 2 as the next digit of the answer. 
Result so far: 248592.0
If we subtract 794 from 1028, we get 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

Going ahead to step 9:
2340 divided by 397 is 5 with a remainder of 355.
Put 5 as the next digit of the answer. 
Result so far: 248592.5
If we subtract 1985 from 2340, we get 355.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3550, and continue the process.

Step 10:
The number 397 fits into 3550 8 times, leaving a remainder of 374.
Record the quotient 8 as the next digit in the result. 
Result so far: 248592.58
Subtracting 3176 from 3550 leaves us with 374.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3740, and continue the process.

Going ahead to step 11:
3740 divided by 397 is 9 with a remainder of 167.
The number 9 becomes the next digit in our result. 
Result so far: 248592.589
If we subtract 3573 from 3740, we get 167.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1670, and continue the process.

Going ahead to step 12:
1670 divided by 397 is 4 with a remainder of 82.
Record the quotient 4 as the next digit in the result. 
Result so far: 248592.5894
Deduct 1588 from 1670 and we're left with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Advancing to step 13:
The number 397 fits into 820 2 times, leaving a remainder of 26.
The next digit of our result is 2. 
Result so far: 248592.58942
Subtract 794 from 820 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 14:
When dividing 260 by 397, we get 0 with a remainder of 260.
The number 0 becomes the next digit in our result. 
Result so far: 248592.58942
Subtract 0 from 260 to get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Advancing to step 15:
2600 divided by 397 is 6 with a remainder of 218.
The number 6 becomes the next digit in our result. 
Result so far: 248592.5894206
If we subtract 2382 from 2600, we get 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Step 16:
2180 divided by 397 is 5 with a remainder of 195.
Put 5 as the next digit of the answer. 
Result so far: 248592.58942065
Subtracting 1985 from 2180 leaves us with 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

After the division, we end up with 248592.58942065 and a remainder of 1.95e-07.
