We look at the division of 86484001 by 243 
We want to figure out the number of times 86484001 can be divided by 243.

Going ahead to step 1:
243 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 243

Advancing to step 2:
If we divide 86 by 243, we get 0 and a remainder of 86.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 86 leaves us with 86.
Take the next digit (4) from the dividend and append it to 86, then repeat: 864 / 243

Moving on to step 3:
864 divided by 243 is 3 with a remainder of 135.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 729 from 864 leaves us with 135.
Bring next digit (8) of the dividend behind the 135 and repeat the process: 1358 / 243

Moving on to step 4:
243 goes into 1358 5 times with a remainder of 143.
The next digit of our result is 5. 
Result so far: 35.0
Deduct 1215 from 1358 and we're left with 143.
Append the next digit (4) from the dividend to 143 and continue with: 1434 / 243

Advancing to step 5:
If we divide 1434 by 243, we get 5 and a remainder of 219.
Use 5 as the next digit of our solution. 
Result so far: 355.0
Subtract 1215 from 1434 to get 219.
Take the next digit (0) from the dividend and append it to 219, then repeat: 2190 / 243

Let's proceed to step 6:
243 can be fit into 2190 9 times, resulting in a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 3559.0
Subtract 2187 from 2190 to get 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 243

Advancing to step 7:
When dividing 30 by 243, we get 0 with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 35590.0
If we take 0 away from 30, we end up with 30.
Append the next digit (1) from the dividend to 30 and continue with: 301 / 243

Going ahead to step 8:
The number 243 fits into 301 1 times, leaving a remainder of 58.
Write down 1 as next digit of the result. 
Result so far: 355901.0
Subtracting 243 from 301 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 9:
243 can be fit into 580 2 times, resulting in a remainder of 94.
The number 2 becomes the next digit in our result. 
Result so far: 355901.2
Subtracting 486 from 580 leaves us with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Going ahead to step 10:
940 divided by 243 is 3 with a remainder of 211.
Write down 3 as next digit of the result. 
Result so far: 355901.23
If we subtract 729 from 940, we get 211.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2110, and continue the process.

Moving on to step 11:
When dividing 2110 by 243, we get 8 with a remainder of 166.
Use 8 as the next digit of our solution. 
Result so far: 355901.238
Subtract 1944 from 2110 to get 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

On to step 12:
243 can be fit into 1660 6 times, resulting in a remainder of 202.
Use 6 as the next digit of our solution. 
Result so far: 355901.2386
Subtract 1458 from 1660 to get 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Let's proceed to step 13:
243 can be fit into 2020 8 times, resulting in a remainder of 76.
Record the quotient 8 as the next digit in the result. 
Result so far: 355901.23868
If we subtract 1944 from 2020, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Going ahead to step 14:
When dividing 760 by 243, we get 3 with a remainder of 31.
Put 3 as the next digit of the answer. 
Result so far: 355901.238683
Subtracting 729 from 760 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 15:
When dividing 310 by 243, we get 1 with a remainder of 67.
Record the quotient 1 as the next digit in the result. 
Result so far: 355901.2386831
Subtract 243 from 310 to get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Going ahead to step 16:
243 can be fit into 670 2 times, resulting in a remainder of 184.
Write down 2 as next digit of the result. 
Result so far: 355901.23868312
If we subtract 486 from 670, we get 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Our division results in 355901.23868312 with a remaining 1.84e-07.
