79389195 divided by 243 
We want to figure out the number of times 79389195 can be divided by 243.

Advancing to step 1:
If we divide 7 by 243, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Grab the next digit (9) from the dividend, add it to 7, then carry on: 79 / 243

Advancing to step 2:
When dividing 79 by 243, we get 0 with a remainder of 79.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 79, we end up with 79.
Append the next digit (3) from the dividend to 79 and continue with: 793 / 243

Step 3:
The number 243 fits into 793 3 times, leaving a remainder of 64.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we subtract 729 from 793, we get 64.
Fetch the next digit (8) from the dividend, attach it to 64 and continue: 648 / 243

Step 4:
243 goes into 648 2 times with a remainder of 162.
The next digit of our result is 2. 
Result so far: 32.0
The remainder is 162 after subtracting 486 from 648.
Include the next digit (9) from the dividend after 162, then repeat: 1629 / 243

Step 5:
243 can be fit into 1629 6 times, resulting in a remainder of 171.
Put 6 as the next digit of the answer. 
Result so far: 326.0
If we subtract 1458 from 1629, we get 171.
Bring next digit (1) of the dividend behind the 171 and repeat the process: 1711 / 243

Advancing to step 6:
When dividing 1711 by 243, we get 7 with a remainder of 10.
Record the quotient 7 as the next digit in the result. 
Result so far: 3267.0
The remainder is 10 after subtracting 1701 from 1711.
Take the next digit (9) from the dividend and append it to 10, then repeat: 109 / 243

Moving on to step 7:
243 goes into 109 0 times with a remainder of 109.
Record the quotient 0 as the next digit in the result. 
Result so far: 32670.0
Subtract 0 from 109 to get 109.
Grab the next digit (5) from the dividend, add it to 109, then carry on: 1095 / 243

Going ahead to step 8:
When dividing 1095 by 243, we get 4 with a remainder of 123.
The next digit of our result is 4. 
Result so far: 326704.0
If we take 972 away from 1095, we end up with 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

Advancing to step 9:
243 goes into 1230 5 times with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 326704.5
The remainder is 15 after subtracting 1215 from 1230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 10:
The number 243 fits into 150 0 times, leaving a remainder of 150.
The number 0 becomes the next digit in our result. 
Result so far: 326704.5
Subtracting 0 from 150 leaves us with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Advancing to step 11:
When dividing 1500 by 243, we get 6 with a remainder of 42.
The next digit of our result is 6. 
Result so far: 326704.506
Subtracting 1458 from 1500 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 12:
If we divide 420 by 243, we get 1 and a remainder of 177.
Use 1 as the next digit of our solution. 
Result so far: 326704.5061
If we subtract 243 from 420, we 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.

Moving on to step 13:
243 goes into 1770 7 times with a remainder of 69.
The number 7 becomes the next digit in our result. 
Result so far: 326704.50617
If we take 1701 away from 1770, we end up with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Advancing to step 14:
The number 243 fits into 690 2 times, leaving a remainder of 204.
Put 2 as the next digit of the answer. 
Result so far: 326704.506172
The remainder is 204 after subtracting 486 from 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Let's proceed to step 15:
If we divide 2040 by 243, we get 8 and a remainder of 96.
Write down 8 as next digit of the result. 
Result so far: 326704.5061728
Deduct 1944 from 2040 and we're left with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Moving on to step 16:
If we divide 960 by 243, we get 3 and a remainder of 231.
Use 3 as the next digit of our solution. 
Result so far: 326704.50617283
Subtracting 729 from 960 leaves us with 231.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2310, and continue the process.

The final outcome is 326704.50617283, with a leftover of 2.31e-07.
