97816864 divided by 243 
Let's see how many times 243 fits into 97816864.

Let's proceed to step 1:
243 can be fit into 9 0 times, resulting in a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Fetch the next digit (7) from the dividend, attach it to 9 and continue: 97 / 243

Going ahead to step 2:
243 goes into 97 0 times with a remainder of 97.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 97 to get 97.
Grab the next digit (8) from the dividend, add it to 97, then carry on: 978 / 243

Going ahead to step 3:
978 divided by 243 is 4 with a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we subtract 972 from 978, we get 6.
Grab the next digit (1) from the dividend, add it to 6, then carry on: 61 / 243

Moving on to step 4:
61 divided by 243 is 0 with a remainder of 61.
The number 0 becomes the next digit in our result. 
Result so far: 40.0
The remainder is 61 after subtracting 0 from 61.
Include the next digit (6) from the dividend after 61, then repeat: 616 / 243

Moving on to step 5:
When dividing 616 by 243, we get 2 with a remainder of 130.
Write down 2 as next digit of the result. 
Result so far: 402.0
Deduct 486 from 616 and we're left with 130.
Fetch the next digit (8) from the dividend, attach it to 130 and continue: 1308 / 243

Moving on to step 6:
1308 divided by 243 is 5 with a remainder of 93.
Put 5 as the next digit of the answer. 
Result so far: 4025.0
If we take 1215 away from 1308, we end up with 93.
Take the next digit (6) from the dividend and append it to 93, then repeat: 936 / 243

Going ahead to step 7:
If we divide 936 by 243, we get 3 and a remainder of 207.
Record the quotient 3 as the next digit in the result. 
Result so far: 40253.0
If we take 729 away from 936, we end up with 207.
Fetch the next digit (4) from the dividend, attach it to 207 and continue: 2074 / 243

On to step 8:
243 can be fit into 2074 8 times, resulting in a remainder of 130.
Record the quotient 8 as the next digit in the result. 
Result so far: 402538.0
The remainder is 130 after subtracting 1944 from 2074.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

On to step 9:
If we divide 1300 by 243, we get 5 and a remainder of 85.
The next digit of our result is 5. 
Result so far: 402538.5
Subtract 1215 from 1300 to get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Let's proceed to step 10:
If we divide 850 by 243, we get 3 and a remainder of 121.
The number 3 becomes the next digit in our result. 
Result so far: 402538.53
If we take 729 away from 850, we end up with 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Moving on to step 11:
If we divide 1210 by 243, we get 4 and a remainder of 238.
Record the quotient 4 as the next digit in the result. 
Result so far: 402538.534
Deduct 972 from 1210 and we're left with 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Moving on to step 12:
The number 243 fits into 2380 9 times, leaving a remainder of 193.
Record the quotient 9 as the next digit in the result. 
Result so far: 402538.5349
Deduct 2187 from 2380 and we're left with 193.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1930, and continue the process.

On to step 13:
The number 243 fits into 1930 7 times, leaving a remainder of 229.
Put 7 as the next digit of the answer. 
Result so far: 402538.53497
Deduct 1701 from 1930 and we're left with 229.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2290, and continue the process.

Step 14:
The number 243 fits into 2290 9 times, leaving a remainder of 103.
Put 9 as the next digit of the answer. 
Result so far: 402538.534979
Subtract 2187 from 2290 to get 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

Let's proceed to step 15:
243 goes into 1030 4 times with a remainder of 58.
Put 4 as the next digit of the answer. 
Result so far: 402538.5349794
Subtracting 972 from 1030 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Going ahead to step 16:
If we divide 580 by 243, we get 2 and a remainder of 94.
Record the quotient 2 as the next digit in the result. 
Result so far: 402538.53497942
If we subtract 486 from 580, we get 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

The final result is 402538.53497942 with a remainder of 9.4e-08.
