98668636 ÷ 561 
We want to figure out the number of times 98668636 can be divided by 561.

Step 1:
The number 561 fits into 9 0 times, leaving a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Include the next digit (8) from the dividend after 9, then repeat: 98 / 561

Moving on to step 2:
When dividing 98 by 561, we get 0 with a remainder of 98.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 98, we get 98.
Grab the next digit (6) from the dividend, add it to 98, then carry on: 986 / 561

Moving on to step 3:
561 goes into 986 1 times with a remainder of 425.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 561 away from 986, we end up with 425.
Grab the next digit (6) from the dividend, add it to 425, then carry on: 4256 / 561

Step 4:
561 can be fit into 4256 7 times, resulting in a remainder of 329.
Put 7 as the next digit of the answer. 
Result so far: 17.0
If we take 3927 away from 4256, we end up with 329.
Include the next digit (8) from the dividend after 329, then repeat: 3298 / 561

Going ahead to step 5:
If we divide 3298 by 561, we get 5 and a remainder of 493.
Write down 5 as next digit of the result. 
Result so far: 175.0
If we take 2805 away from 3298, we end up with 493.
Append the next digit (6) from the dividend to 493 and continue with: 4936 / 561

Let's proceed to step 6:
When dividing 4936 by 561, we get 8 with a remainder of 448.
Record the quotient 8 as the next digit in the result. 
Result so far: 1758.0
If we take 4488 away from 4936, we end up with 448.
Include the next digit (3) from the dividend after 448, then repeat: 4483 / 561

Let's proceed to step 7:
561 goes into 4483 7 times with a remainder of 556.
The number 7 becomes the next digit in our result. 
Result so far: 17587.0
The remainder is 556 after subtracting 3927 from 4483.
Take the next digit (6) from the dividend and append it to 556, then repeat: 5566 / 561

Step 8:
If we divide 5566 by 561, we get 9 and a remainder of 517.
Write down 9 as next digit of the result. 
Result so far: 175879.0
If we subtract 5049 from 5566, we get 517.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5170, and continue the process.

Going ahead to step 9:
When dividing 5170 by 561, we get 9 with a remainder of 121.
Put 9 as the next digit of the answer. 
Result so far: 175879.9
Subtract 5049 from 5170 to get 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

On to step 10:
When dividing 1210 by 561, we get 2 with a remainder of 88.
Record the quotient 2 as the next digit in the result. 
Result so far: 175879.92
Subtract 1122 from 1210 to get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Moving on to step 11:
561 goes into 880 1 times with a remainder of 319.
Write down 1 as next digit of the result. 
Result so far: 175879.921
Subtracting 561 from 880 leaves us with 319.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3190, and continue the process.

Going ahead to step 12:
When dividing 3190 by 561, we get 5 with a remainder of 385.
Put 5 as the next digit of the answer. 
Result so far: 175879.9215
If we subtract 2805 from 3190, we get 385.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3850, and continue the process.

On to step 13:
561 can be fit into 3850 6 times, resulting in a remainder of 484.
Write down 6 as next digit of the result. 
Result so far: 175879.92156
Subtract 3366 from 3850 to get 484.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4840, and continue the process.

On to step 14:
4840 divided by 561 is 8 with a remainder of 352.
Record the quotient 8 as the next digit in the result. 
Result so far: 175879.921568
Subtract 4488 from 4840 to get 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Moving on to step 15:
If we divide 3520 by 561, we get 6 and a remainder of 154.
Put 6 as the next digit of the answer. 
Result so far: 175879.9215686
Subtract 3366 from 3520 to get 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Moving on to step 16:
561 can be fit into 1540 2 times, resulting in a remainder of 418.
Record the quotient 2 as the next digit in the result. 
Result so far: 175879.92156862
If we subtract 1122 from 1540, we get 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

The final result is 175879.92156862 with a remainder of 4.18e-07.
