We look at the division of 98706690 by 257 
We're looking to find how many times 257 goes into 98706690.

Going ahead to step 1:
9 divided by 257 is 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Bring next digit (8) of the dividend behind the 9 and repeat the process: 98 / 257

Step 2:
98 divided by 257 is 0 with a remainder of 98.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 98 leaves us with 98.
Fetch the next digit (7) from the dividend, attach it to 98 and continue: 987 / 257

Step 3:
257 can be fit into 987 3 times, resulting in a remainder of 216.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Deduct 771 from 987 and we're left with 216.
Include the next digit (0) from the dividend after 216, then repeat: 2160 / 257

Going ahead to step 4:
The number 257 fits into 2160 8 times, leaving a remainder of 104.
The next digit of our result is 8. 
Result so far: 38.0
Subtract 2056 from 2160 to get 104.
Bring next digit (6) of the dividend behind the 104 and repeat the process: 1046 / 257

Advancing to step 5:
When dividing 1046 by 257, we get 4 with a remainder of 18.
The next digit of our result is 4. 
Result so far: 384.0
The remainder is 18 after subtracting 1028 from 1046.
Append the next digit (6) from the dividend to 18 and continue with: 186 / 257

On to step 6:
257 can be fit into 186 0 times, resulting in a remainder of 186.
Write down 0 as next digit of the result. 
Result so far: 3840.0
If we subtract 0 from 186, we get 186.
Fetch the next digit (9) from the dividend, attach it to 186 and continue: 1869 / 257

On to step 7:
257 can be fit into 1869 7 times, resulting in a remainder of 70.
The next digit of our result is 7. 
Result so far: 38407.0
Subtract 1799 from 1869 to get 70.
Grab the next digit (0) from the dividend, add it to 70, then carry on: 700 / 257

Moving on to step 8:
When dividing 700 by 257, we get 2 with a remainder of 186.
Put 2 as the next digit of the answer. 
Result so far: 384072.0
Subtract 514 from 700 to get 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Moving on to step 9:
The number 257 fits into 1860 7 times, leaving a remainder of 61.
Write down 7 as next digit of the result. 
Result so far: 384072.7
If we take 1799 away from 1860, we end up with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Step 10:
610 divided by 257 is 2 with a remainder of 96.
The number 2 becomes the next digit in our result. 
Result so far: 384072.72
Deduct 514 from 610 and we're left with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Advancing to step 11:
The number 257 fits into 960 3 times, leaving a remainder of 189.
The next digit of our result is 3. 
Result so far: 384072.723
Subtracting 771 from 960 leaves us with 189.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1890, and continue the process.

Advancing to step 12:
257 can be fit into 1890 7 times, resulting in a remainder of 91.
Put 7 as the next digit of the answer. 
Result so far: 384072.7237
If we take 1799 away from 1890, we end up with 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Going ahead to step 13:
When dividing 910 by 257, we get 3 with a remainder of 139.
The number 3 becomes the next digit in our result. 
Result so far: 384072.72373
The remainder is 139 after subtracting 771 from 910.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

Advancing to step 14:
1390 divided by 257 is 5 with a remainder of 105.
Write down 5 as next digit of the result. 
Result so far: 384072.723735
The remainder is 105 after subtracting 1285 from 1390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Going ahead to step 15:
257 can be fit into 1050 4 times, resulting in a remainder of 22.
Record the quotient 4 as the next digit in the result. 
Result so far: 384072.7237354
Deduct 1028 from 1050 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 16:
When dividing 220 by 257, we get 0 with a remainder of 220.
Write down 0 as next digit of the result. 
Result so far: 384072.7237354
Deduct 0 from 220 and we're left with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

After the division, we end up with 384072.7237354 and a remainder of 2.2e-07.
