We're dividing 45426731 by 243 
Our goal is to divide 45426731 by 243.

Let's proceed to step 1:
If we divide 4 by 243, we get 0 and a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 243

On to step 2:
If we divide 45 by 243, we get 0 and a remainder of 45.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 45 to get 45.
Take the next digit (4) from the dividend and append it to 45, then repeat: 454 / 243

Advancing to step 3:
454 divided by 243 is 1 with a remainder of 211.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 243 from 454 to get 211.
Bring next digit (2) of the dividend behind the 211 and repeat the process: 2112 / 243

Let's proceed to step 4:
If we divide 2112 by 243, we get 8 and a remainder of 168.
Use 8 as the next digit of our solution. 
Result so far: 18.0
If we take 1944 away from 2112, we end up with 168.
Append the next digit (6) from the dividend to 168 and continue with: 1686 / 243

Let's proceed to step 5:
1686 divided by 243 is 6 with a remainder of 228.
The number 6 becomes the next digit in our result. 
Result so far: 186.0
If we take 1458 away from 1686, we end up with 228.
Grab the next digit (7) from the dividend, add it to 228, then carry on: 2287 / 243

Step 6:
243 can be fit into 2287 9 times, resulting in a remainder of 100.
The number 9 becomes the next digit in our result. 
Result so far: 1869.0
The remainder is 100 after subtracting 2187 from 2287.
Grab the next digit (3) from the dividend, add it to 100, then carry on: 1003 / 243

Moving on to step 7:
1003 divided by 243 is 4 with a remainder of 31.
Use 4 as the next digit of our solution. 
Result so far: 18694.0
The remainder is 31 after subtracting 972 from 1003.
Take the next digit (1) from the dividend and append it to 31, then repeat: 311 / 243

Step 8:
If we divide 311 by 243, we get 1 and a remainder of 68.
Write down 1 as next digit of the result. 
Result so far: 186941.0
Subtracting 243 from 311 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 9:
If we divide 680 by 243, we get 2 and a remainder of 194.
Record the quotient 2 as the next digit in the result. 
Result so far: 186941.2
If we subtract 486 from 680, we get 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

Step 10:
243 can be fit into 1940 7 times, resulting in a remainder of 239.
Use 7 as the next digit of our solution. 
Result so far: 186941.27
Subtract 1701 from 1940 to get 239.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2390, and continue the process.

On to step 11:
243 can be fit into 2390 9 times, resulting in a remainder of 203.
The next digit of our result is 9. 
Result so far: 186941.279
If we subtract 2187 from 2390, we get 203.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2030, and continue the process.

Advancing to step 12:
When dividing 2030 by 243, we get 8 with a remainder of 86.
The number 8 becomes the next digit in our result. 
Result so far: 186941.2798
Deduct 1944 from 2030 and we're left with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

On to step 13:
243 goes into 860 3 times with a remainder of 131.
The next digit of our result is 3. 
Result so far: 186941.27983
If we take 729 away from 860, we end up with 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

Going ahead to step 14:
When dividing 1310 by 243, we get 5 with a remainder of 95.
The number 5 becomes the next digit in our result. 
Result so far: 186941.279835
Subtract 1215 from 1310 to get 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Going ahead to step 15:
If we divide 950 by 243, we get 3 and a remainder of 221.
Use 3 as the next digit of our solution. 
Result so far: 186941.2798353
The remainder is 221 after subtracting 729 from 950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2210, and continue the process.

On to step 16:
The number 243 fits into 2210 9 times, leaving a remainder of 23.
The number 9 becomes the next digit in our result. 
Result so far: 186941.27983539
Deduct 2187 from 2210 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

After the division, we end up with 186941.27983539 and a remainder of 2.3e-08.
