We're dividing 72426517 by 243 
We want to figure out the number of times 72426517 can be divided by 243.

On to step 1:
7 divided by 243 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 243

Step 2:
243 goes into 72 0 times with a remainder of 72.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 72 leaves us with 72.
Take the next digit (4) from the dividend and append it to 72, then repeat: 724 / 243

On to step 3:
When dividing 724 by 243, we get 2 with a remainder of 238.
The next digit of our result is 2. 
Result so far: 2.0
If we take 486 away from 724, we end up with 238.
Bring next digit (2) of the dividend behind the 238 and repeat the process: 2382 / 243

Let's proceed to step 4:
243 goes into 2382 9 times with a remainder of 195.
Write down 9 as next digit of the result. 
Result so far: 29.0
Subtracting 2187 from 2382 leaves us with 195.
Fetch the next digit (6) from the dividend, attach it to 195 and continue: 1956 / 243

Let's proceed to step 5:
When dividing 1956 by 243, we get 8 with a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 298.0
If we subtract 1944 from 1956, we get 12.
Append the next digit (5) from the dividend to 12 and continue with: 125 / 243

Moving on to step 6:
If we divide 125 by 243, we get 0 and a remainder of 125.
Use 0 as the next digit of our solution. 
Result so far: 2980.0
Deduct 0 from 125 and we're left with 125.
Append the next digit (1) from the dividend to 125 and continue with: 1251 / 243

Step 7:
1251 divided by 243 is 5 with a remainder of 36.
Use 5 as the next digit of our solution. 
Result so far: 29805.0
If we subtract 1215 from 1251, we get 36.
Append the next digit (7) from the dividend to 36 and continue with: 367 / 243

Let's proceed to step 8:
243 goes into 367 1 times with a remainder of 124.
Use 1 as the next digit of our solution. 
Result so far: 298051.0
Subtract 243 from 367 to get 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

On to step 9:
If we divide 1240 by 243, we get 5 and a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 298051.5
Subtracting 1215 from 1240 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 10:
If we divide 250 by 243, we get 1 and a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 298051.51
If we take 243 away from 250, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 11:
243 can be fit into 70 0 times, resulting in a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 298051.51
Deduct 0 from 70 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 12:
The number 243 fits into 700 2 times, leaving a remainder of 214.
Record the quotient 2 as the next digit in the result. 
Result so far: 298051.5102
The remainder is 214 after subtracting 486 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Step 13:
When dividing 2140 by 243, we get 8 with a remainder of 196.
Use 8 as the next digit of our solution. 
Result so far: 298051.51028
If we subtract 1944 from 2140, we get 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Going ahead to step 14:
If we divide 1960 by 243, we get 8 and a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 298051.510288
Subtract 1944 from 1960 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Our division results in 298051.510288 with a remaining 1.6e-06.
