97399215 ÷ 561 
Let's see how many times 561 fits into 97399215.

Step 1:
9 divided by 561 is 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Append the next digit (7) from the dividend to 9 and continue with: 97 / 561

Let's proceed to step 2:
97 divided by 561 is 0 with a remainder of 97.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 97, we get 97.
Fetch the next digit (3) from the dividend, attach it to 97 and continue: 973 / 561

Let's proceed to step 3:
561 goes into 973 1 times with a remainder of 412.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 561 from 973 and we're left with 412.
Take the next digit (9) from the dividend and append it to 412, then repeat: 4129 / 561

Let's proceed to step 4:
When dividing 4129 by 561, we get 7 with a remainder of 202.
The next digit of our result is 7. 
Result so far: 17.0
If we subtract 3927 from 4129, we get 202.
Bring next digit (9) of the dividend behind the 202 and repeat the process: 2029 / 561

On to step 5:
When dividing 2029 by 561, we get 3 with a remainder of 346.
The number 3 becomes the next digit in our result. 
Result so far: 173.0
If we subtract 1683 from 2029, we get 346.
Fetch the next digit (2) from the dividend, attach it to 346 and continue: 3462 / 561

Advancing to step 6:
561 can be fit into 3462 6 times, resulting in a remainder of 96.
The next digit of our result is 6. 
Result so far: 1736.0
If we subtract 3366 from 3462, we get 96.
Bring next digit (1) of the dividend behind the 96 and repeat the process: 961 / 561

Step 7:
561 goes into 961 1 times with a remainder of 400.
Record the quotient 1 as the next digit in the result. 
Result so far: 17361.0
The remainder is 400 after subtracting 561 from 961.
Take the next digit (5) from the dividend and append it to 400, then repeat: 4005 / 561

On to step 8:
If we divide 4005 by 561, we get 7 and a remainder of 78.
The number 7 becomes the next digit in our result. 
Result so far: 173617.0
Deduct 3927 from 4005 and we're left with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Moving on to step 9:
The number 561 fits into 780 1 times, leaving a remainder of 219.
Write down 1 as next digit of the result. 
Result so far: 173617.1
Deduct 561 from 780 and we're left with 219.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2190, and continue the process.

On to step 10:
561 goes into 2190 3 times with a remainder of 507.
The number 3 becomes the next digit in our result. 
Result so far: 173617.13
Subtract 1683 from 2190 to get 507.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5070, and continue the process.

Going ahead to step 11:
561 can be fit into 5070 9 times, resulting in a remainder of 21.
Use 9 as the next digit of our solution. 
Result so far: 173617.139
Subtracting 5049 from 5070 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 12:
561 can be fit into 210 0 times, resulting in a remainder of 210.
The next digit of our result is 0. 
Result so far: 173617.139
If we subtract 0 from 210, we get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Going ahead to step 13:
The number 561 fits into 2100 3 times, leaving a remainder of 417.
The next digit of our result is 3. 
Result so far: 173617.13903
If we subtract 1683 from 2100, we get 417.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4170, and continue the process.

Advancing to step 14:
If we divide 4170 by 561, we get 7 and a remainder of 243.
The next digit of our result is 7. 
Result so far: 173617.139037
Subtract 3927 from 4170 to get 243.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2430, and continue the process.

Let's proceed to step 15:
If we divide 2430 by 561, we get 4 and a remainder of 186.
Put 4 as the next digit of the answer. 
Result so far: 173617.1390374
The remainder is 186 after subtracting 2244 from 2430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Step 16:
If we divide 1860 by 561, we get 3 and a remainder of 177.
The number 3 becomes the next digit in our result. 
Result so far: 173617.13903743
Subtract 1683 from 1860 to get 177.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1770, and continue the process.

The final result is 173617.13903743 with a remainder of 1.77e-07.
