Let's divide 90565317 by 561
We want to figure out the number of times 90565317 can be divided by 561.

Let's proceed to step 1:
561 can be fit into 9 0 times, resulting in a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Bring next digit (0) of the dividend behind the 9 and repeat the process: 90 / 561

Let's proceed to step 2:
561 goes into 90 0 times with a remainder of 90.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 90 to get 90.
Take the next digit (5) from the dividend and append it to 90, then repeat: 905 / 561

Advancing to step 3:
561 goes into 905 1 times with a remainder of 344.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 561 from 905 and we're left with 344.
Fetch the next digit (6) from the dividend, attach it to 344 and continue: 3446 / 561

Going ahead to step 4:
When dividing 3446 by 561, we get 6 with a remainder of 80.
Use 6 as the next digit of our solution. 
Result so far: 16.0
Subtracting 3366 from 3446 leaves us with 80.
Include the next digit (5) from the dividend after 80, then repeat: 805 / 561

Advancing to step 5:
561 goes into 805 1 times with a remainder of 244.
Write down 1 as next digit of the result. 
Result so far: 161.0
Subtracting 561 from 805 leaves us with 244.
Fetch the next digit (3) from the dividend, attach it to 244 and continue: 2443 / 561

On to step 6:
561 can be fit into 2443 4 times, resulting in a remainder of 199.
The number 4 becomes the next digit in our result. 
Result so far: 1614.0
Subtract 2244 from 2443 to get 199.
Include the next digit (1) from the dividend after 199, then repeat: 1991 / 561

Let's proceed to step 7:
The number 561 fits into 1991 3 times, leaving a remainder of 308.
Write down 3 as next digit of the result. 
Result so far: 16143.0
Deduct 1683 from 1991 and we're left with 308.
Include the next digit (7) from the dividend after 308, then repeat: 3087 / 561

Let's proceed to step 8:
If we divide 3087 by 561, we get 5 and a remainder of 282.
Write down 5 as next digit of the result. 
Result so far: 161435.0
If we subtract 2805 from 3087, we get 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Going ahead to step 9:
561 goes into 2820 5 times with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 161435.5
If we take 2805 away from 2820, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 10:
The number 561 fits into 150 0 times, leaving a remainder of 150.
The number 0 becomes the next digit in our result. 
Result so far: 161435.5
Subtracting 0 from 150 leaves us with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Advancing to step 11:
The number 561 fits into 1500 2 times, leaving a remainder of 378.
Write down 2 as next digit of the result. 
Result so far: 161435.502
If we subtract 1122 from 1500, we get 378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

Advancing to step 12:
The number 561 fits into 3780 6 times, leaving a remainder of 414.
Record the quotient 6 as the next digit in the result. 
Result so far: 161435.5026
If we take 3366 away from 3780, we end up with 414.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4140, and continue the process.

Moving on to step 13:
The number 561 fits into 4140 7 times, leaving a remainder of 213.
The next digit of our result is 7. 
Result so far: 161435.50267
The remainder is 213 after subtracting 3927 from 4140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2130, and continue the process.

Let's proceed to step 14:
When dividing 2130 by 561, we get 3 with a remainder of 447.
The next digit of our result is 3. 
Result so far: 161435.502673
If we take 1683 away from 2130, we end up with 447.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4470, and continue the process.

Advancing to step 15:
561 goes into 4470 7 times with a remainder of 543.
The next digit of our result is 7. 
Result so far: 161435.5026737
Subtract 3927 from 4470 to get 543.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5430, and continue the process.

Advancing to step 16:
561 goes into 5430 9 times with a remainder of 381.
Record the quotient 9 as the next digit in the result. 
Result so far: 161435.50267379
If we take 5049 away from 5430, we end up with 381.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3810, and continue the process.

The final result is 161435.50267379 with a remainder of 3.81e-07.
