73902023 ÷ 237 
Our goal is to divide 73902023 by 237.

Going ahead to step 1:
237 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Include the next digit (3) from the dividend after 7, then repeat: 73 / 237

Advancing to step 2:
237 goes into 73 0 times with a remainder of 73.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 73 and we're left with 73.
Bring next digit (9) of the dividend behind the 73 and repeat the process: 739 / 237

Step 3:
237 goes into 739 3 times with a remainder of 28.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we subtract 711 from 739, we get 28.
Bring next digit (0) of the dividend behind the 28 and repeat the process: 280 / 237

Let's proceed to step 4:
237 goes into 280 1 times with a remainder of 43.
The number 1 becomes the next digit in our result. 
Result so far: 31.0
If we subtract 237 from 280, we get 43.
Fetch the next digit (2) from the dividend, attach it to 43 and continue: 432 / 237

Step 5:
237 can be fit into 432 1 times, resulting in a remainder of 195.
Use 1 as the next digit of our solution. 
Result so far: 311.0
Subtracting 237 from 432 leaves us with 195.
Append the next digit (0) from the dividend to 195 and continue with: 1950 / 237

Advancing to step 6:
237 can be fit into 1950 8 times, resulting in a remainder of 54.
The number 8 becomes the next digit in our result. 
Result so far: 3118.0
The remainder is 54 after subtracting 1896 from 1950.
Fetch the next digit (2) from the dividend, attach it to 54 and continue: 542 / 237

On to step 7:
When dividing 542 by 237, we get 2 with a remainder of 68.
The next digit of our result is 2. 
Result so far: 31182.0
Deduct 474 from 542 and we're left with 68.
Append the next digit (3) from the dividend to 68 and continue with: 683 / 237

Step 8:
When dividing 683 by 237, we get 2 with a remainder of 209.
Write down 2 as next digit of the result. 
Result so far: 311822.0
Deduct 474 from 683 and we're left with 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

Advancing to step 9:
When dividing 2090 by 237, we get 8 with a remainder of 194.
The number 8 becomes the next digit in our result. 
Result so far: 311822.8
The remainder is 194 after subtracting 1896 from 2090.
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:
The number 237 fits into 1940 8 times, leaving a remainder of 44.
Put 8 as the next digit of the answer. 
Result so far: 311822.88
If we take 1896 away from 1940, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

After the division, we end up with 311822.88 and a remainder of 0.044.
