98635450 divided by 649 
Our goal is to divide 98635450 by 649.

Moving on to step 1:
When dividing 9 by 649, we get 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Append the next digit (8) from the dividend to 9 and continue with: 98 / 649

On to step 2:
When dividing 98 by 649, we get 0 with a remainder of 98.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 98 and we're left with 98.
Fetch the next digit (6) from the dividend, attach it to 98 and continue: 986 / 649

Advancing to step 3:
649 can be fit into 986 1 times, resulting in a remainder of 337.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 649 from 986 to get 337.
Append the next digit (3) from the dividend to 337 and continue with: 3373 / 649

Step 4:
The number 649 fits into 3373 5 times, leaving a remainder of 128.
The next digit of our result is 5. 
Result so far: 15.0
The remainder is 128 after subtracting 3245 from 3373.
Fetch the next digit (5) from the dividend, attach it to 128 and continue: 1285 / 649

Going ahead to step 5:
649 can be fit into 1285 1 times, resulting in a remainder of 636.
Put 1 as the next digit of the answer. 
Result so far: 151.0
If we take 649 away from 1285, we end up with 636.
Fetch the next digit (4) from the dividend, attach it to 636 and continue: 6364 / 649

Let's proceed to step 6:
6364 divided by 649 is 9 with a remainder of 523.
Write down 9 as next digit of the result. 
Result so far: 1519.0
The remainder is 523 after subtracting 5841 from 6364.
Grab the next digit (5) from the dividend, add it to 523, then carry on: 5235 / 649

Advancing to step 7:
649 goes into 5235 8 times with a remainder of 43.
Write down 8 as next digit of the result. 
Result so far: 15198.0
Deduct 5192 from 5235 and we're left with 43.
Append the next digit (0) from the dividend to 43 and continue with: 430 / 649

Let's proceed to step 8:
430 divided by 649 is 0 with a remainder of 430.
Put 0 as the next digit of the answer. 
Result so far: 151980.0
Deduct 0 from 430 and we're left with 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Step 9:
When dividing 4300 by 649, we get 6 with a remainder of 406.
Record the quotient 6 as the next digit in the result. 
Result so far: 151980.6
The remainder is 406 after subtracting 3894 from 4300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

Advancing to step 10:
The number 649 fits into 4060 6 times, leaving a remainder of 166.
The next digit of our result is 6. 
Result so far: 151980.66
If we take 3894 away from 4060, we end up with 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

The final result is 151980.66 with a remainder of 0.166.
