We divide 86732536 by 243
The aim is to understand the frequency of 243 in 86732536.

Let's proceed to step 1:
When dividing 8 by 243, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 243

Let's proceed to step 2:
243 can be fit into 86 0 times, resulting in a remainder of 86.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 86 after subtracting 0 from 86.
Include the next digit (7) from the dividend after 86, then repeat: 867 / 243

On to step 3:
The number 243 fits into 867 3 times, leaving a remainder of 138.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we take 729 away from 867, we end up with 138.
Fetch the next digit (3) from the dividend, attach it to 138 and continue: 1383 / 243

Step 4:
If we divide 1383 by 243, we get 5 and a remainder of 168.
The next digit of our result is 5. 
Result so far: 35.0
If we subtract 1215 from 1383, we get 168.
Fetch the next digit (2) from the dividend, attach it to 168 and continue: 1682 / 243

Going ahead to step 5:
243 can be fit into 1682 6 times, resulting in a remainder of 224.
The number 6 becomes the next digit in our result. 
Result so far: 356.0
If we take 1458 away from 1682, we end up with 224.
Append the next digit (5) from the dividend to 224 and continue with: 2245 / 243

Going ahead to step 6:
If we divide 2245 by 243, we get 9 and a remainder of 58.
Write down 9 as next digit of the result. 
Result so far: 3569.0
If we take 2187 away from 2245, we end up with 58.
Append the next digit (3) from the dividend to 58 and continue with: 583 / 243

Step 7:
When dividing 583 by 243, we get 2 with a remainder of 97.
Record the quotient 2 as the next digit in the result. 
Result so far: 35692.0
If we subtract 486 from 583, we get 97.
Take the next digit (6) from the dividend and append it to 97, then repeat: 976 / 243

Going ahead to step 8:
If we divide 976 by 243, we get 4 and a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 356924.0
The remainder is 4 after subtracting 972 from 976.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 9:
If we divide 40 by 243, we get 0 and a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 356924.0
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 10:
243 goes into 400 1 times with a remainder of 157.
Put 1 as the next digit of the answer. 
Result so far: 356924.01
Deduct 243 from 400 and we're left with 157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

Going ahead to step 11:
243 can be fit into 1570 6 times, resulting in a remainder of 112.
Use 6 as the next digit of our solution. 
Result so far: 356924.016
If we subtract 1458 from 1570, we get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Step 12:
If we divide 1120 by 243, we get 4 and a remainder of 148.
Use 4 as the next digit of our solution. 
Result so far: 356924.0164
Deduct 972 from 1120 and we're left with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Let's proceed to step 13:
When dividing 1480 by 243, we get 6 with a remainder of 22.
Put 6 as the next digit of the answer. 
Result so far: 356924.01646
If we take 1458 away from 1480, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 14:
The number 243 fits into 220 0 times, leaving a remainder of 220.
The number 0 becomes the next digit in our result. 
Result so far: 356924.01646
The remainder is 220 after subtracting 0 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Moving on to step 15:
If we divide 2200 by 243, we get 9 and a remainder of 13.
The number 9 becomes the next digit in our result. 
Result so far: 356924.0164609
If we take 2187 away from 2200, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 16:
243 can be fit into 130 0 times, resulting in a remainder of 130.
Record the quotient 0 as the next digit in the result. 
Result so far: 356924.0164609
Deduct 0 from 130 and we're left with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

After the division, we end up with 356924.0164609 and a remainder of 1.3e-07.
