We're dividing 15194691 by 243 
We want to figure out the number of times 15194691 can be divided by 243.

On to step 1:
The number 243 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 243

On to step 2:
When dividing 15 by 243, we get 0 with a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 15, we get 15.
Grab the next digit (1) from the dividend, add it to 15, then carry on: 151 / 243

Advancing to step 3:
If we divide 151 by 243, we get 0 and a remainder of 151.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 151, we get 151.
Append the next digit (9) from the dividend to 151 and continue with: 1519 / 243

Let's proceed to step 4:
When dividing 1519 by 243, we get 6 with a remainder of 61.
Use 6 as the next digit of our solution. 
Result so far: 6.0
The remainder is 61 after subtracting 1458 from 1519.
Include the next digit (4) from the dividend after 61, then repeat: 614 / 243

Step 5:
614 divided by 243 is 2 with a remainder of 128.
Put 2 as the next digit of the answer. 
Result so far: 62.0
If we subtract 486 from 614, we get 128.
Append the next digit (6) from the dividend to 128 and continue with: 1286 / 243

Moving on to step 6:
If we divide 1286 by 243, we get 5 and a remainder of 71.
Write down 5 as next digit of the result. 
Result so far: 625.0
If we subtract 1215 from 1286, we get 71.
Fetch the next digit (9) from the dividend, attach it to 71 and continue: 719 / 243

On to step 7:
719 divided by 243 is 2 with a remainder of 233.
Write down 2 as next digit of the result. 
Result so far: 6252.0
Subtract 486 from 719 to get 233.
Fetch the next digit (1) from the dividend, attach it to 233 and continue: 2331 / 243

Let's proceed to step 8:
2331 divided by 243 is 9 with a remainder of 144.
The next digit of our result is 9. 
Result so far: 62529.0
Subtracting 2187 from 2331 leaves us with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Moving on to step 9:
243 can be fit into 1440 5 times, resulting in a remainder of 225.
Use 5 as the next digit of our solution. 
Result so far: 62529.5
If we subtract 1215 from 1440, we get 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Going ahead to step 10:
2250 divided by 243 is 9 with a remainder of 63.
The number 9 becomes the next digit in our result. 
Result so far: 62529.59
The remainder is 63 after subtracting 2187 from 2250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Moving on to step 11:
When dividing 630 by 243, we get 2 with a remainder of 144.
Write down 2 as next digit of the result. 
Result so far: 62529.592
The remainder is 144 after subtracting 486 from 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Step 12:
When dividing 1440 by 243, we get 5 with a remainder of 225.
Write down 5 as next digit of the result. 
Result so far: 62529.5925
The remainder is 225 after subtracting 1215 from 1440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Going ahead to step 13:
2250 divided by 243 is 9 with a remainder of 63.
The next digit of our result is 9. 
Result so far: 62529.59259
If we subtract 2187 from 2250, we get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Moving on to step 14:
243 can be fit into 630 2 times, resulting in a remainder of 144.
The next digit of our result is 2. 
Result so far: 62529.592592
Subtracting 486 from 630 leaves us with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

On to step 15:
243 can be fit into 1440 5 times, resulting in a remainder of 225.
Use 5 as the next digit of our solution. 
Result so far: 62529.5925925
Subtracting 1215 from 1440 leaves us with 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Let's proceed to step 16:
243 can be fit into 2250 9 times, resulting in a remainder of 63.
Use 9 as the next digit of our solution. 
Result so far: 62529.59259259
The remainder is 63 after subtracting 2187 from 2250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

The final outcome is 62529.59259259, with a leftover of 6.3e-08.
