37430593 ÷ 309 
Our goal is to divide 37430593 by 309.

On to step 1:
309 goes into 3 0 times with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 309

Let's proceed to step 2:
When dividing 37 by 309, we get 0 with a remainder of 37.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 37, we end up with 37.
Append the next digit (4) from the dividend to 37 and continue with: 374 / 309

Going ahead to step 3:
309 can be fit into 374 1 times, resulting in a remainder of 65.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 309 from 374 to get 65.
Bring next digit (3) of the dividend behind the 65 and repeat the process: 653 / 309

Let's proceed to step 4:
If we divide 653 by 309, we get 2 and a remainder of 35.
The next digit of our result is 2. 
Result so far: 12.0
Subtracting 618 from 653 leaves us with 35.
Fetch the next digit (0) from the dividend, attach it to 35 and continue: 350 / 309

Advancing to step 5:
309 can be fit into 350 1 times, resulting in a remainder of 41.
The next digit of our result is 1. 
Result so far: 121.0
Subtracting 309 from 350 leaves us with 41.
Fetch the next digit (5) from the dividend, attach it to 41 and continue: 415 / 309

Let's proceed to step 6:
When dividing 415 by 309, we get 1 with a remainder of 106.
Put 1 as the next digit of the answer. 
Result so far: 1211.0
Subtracting 309 from 415 leaves us with 106.
Take the next digit (9) from the dividend and append it to 106, then repeat: 1069 / 309

Let's proceed to step 7:
1069 divided by 309 is 3 with a remainder of 142.
The next digit of our result is 3. 
Result so far: 12113.0
Subtracting 927 from 1069 leaves us with 142.
Include the next digit (3) from the dividend after 142, then repeat: 1423 / 309

Advancing to step 8:
When dividing 1423 by 309, we get 4 with a remainder of 187.
The number 4 becomes the next digit in our result. 
Result so far: 121134.0
If we take 1236 away from 1423, we end up with 187.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

Advancing to step 9:
The number 309 fits into 1870 6 times, leaving a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 121134.6
Subtracting 1854 from 1870 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 10:
If we divide 160 by 309, we get 0 and a remainder of 160.
Write down 0 as next digit of the result. 
Result so far: 121134.6
If we subtract 0 from 160, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

On to step 11:
If we divide 1600 by 309, we get 5 and a remainder of 55.
Use 5 as the next digit of our solution. 
Result so far: 121134.605
The remainder is 55 after subtracting 1545 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

On to step 12:
309 goes into 550 1 times with a remainder of 241.
Use 1 as the next digit of our solution. 
Result so far: 121134.6051
Subtracting 309 from 550 leaves us with 241.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2410, and continue the process.

Step 13:
The number 309 fits into 2410 7 times, leaving a remainder of 247.
Put 7 as the next digit of the answer. 
Result so far: 121134.60517
Subtracting 2163 from 2410 leaves us with 247.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2470, and continue the process.

On to step 14:
309 can be fit into 2470 7 times, resulting in a remainder of 307.
The number 7 becomes the next digit in our result. 
Result so far: 121134.605177
If we take 2163 away from 2470, we end up with 307.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3070, and continue the process.

In conclusion, the division gives 121134.605177 with a balance of 3.07e-05.
