40050430 ÷ 310 
We want to figure out the number of times 40050430 can be divided by 310.

Let's proceed to step 1:
310 can be fit into 4 0 times, resulting in a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 310

Moving on to step 2:
310 goes into 40 0 times with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 40 to get 40.
Include the next digit (0) from the dividend after 40, then repeat: 400 / 310

Going ahead to step 3:
When dividing 400 by 310, we get 1 with a remainder of 90.
The next digit of our result is 1. 
Result so far: 1.0
If we take 310 away from 400, we end up with 90.
Fetch the next digit (5) from the dividend, attach it to 90 and continue: 905 / 310

Going ahead to step 4:
The number 310 fits into 905 2 times, leaving a remainder of 285.
Put 2 as the next digit of the answer. 
Result so far: 12.0
If we subtract 620 from 905, we get 285.
Bring next digit (0) of the dividend behind the 285 and repeat the process: 2850 / 310

Step 5:
310 goes into 2850 9 times with a remainder of 60.
The number 9 becomes the next digit in our result. 
Result so far: 129.0
The remainder is 60 after subtracting 2790 from 2850.
Include the next digit (4) from the dividend after 60, then repeat: 604 / 310

Moving on to step 6:
310 can be fit into 604 1 times, resulting in a remainder of 294.
Record the quotient 1 as the next digit in the result. 
Result so far: 1291.0
Subtract 310 from 604 to get 294.
Grab the next digit (3) from the dividend, add it to 294, then carry on: 2943 / 310

On to step 7:
310 can be fit into 2943 9 times, resulting in a remainder of 153.
The number 9 becomes the next digit in our result. 
Result so far: 12919.0
If we subtract 2790 from 2943, we get 153.
Include the next digit (0) from the dividend after 153, then repeat: 1530 / 310

Advancing to step 8:
310 can be fit into 1530 4 times, resulting in a remainder of 290.
Write down 4 as next digit of the result. 
Result so far: 129194.0
If we subtract 1240 from 1530, we get 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Going ahead to step 9:
If we divide 2900 by 310, we get 9 and a remainder of 110.
The number 9 becomes the next digit in our result. 
Result so far: 129194.9
Subtract 2790 from 2900 to get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Let's proceed to step 10:
If we divide 1100 by 310, we get 3 and a remainder of 170.
The next digit of our result is 3. 
Result so far: 129194.93
Deduct 930 from 1100 and we're left with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Step 11:
If we divide 1700 by 310, we get 5 and a remainder of 150.
The next digit of our result is 5. 
Result so far: 129194.935
Subtracting 1550 from 1700 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.

Step 12:
310 goes into 1500 4 times with a remainder of 260.
Write down 4 as next digit of the result. 
Result so far: 129194.9354
The remainder is 260 after subtracting 1240 from 1500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Step 13:
If we divide 2600 by 310, we get 8 and a remainder of 120.
The next digit of our result is 8. 
Result so far: 129194.93548
Subtracting 2480 from 2600 leaves us with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Advancing to step 14:
1200 divided by 310 is 3 with a remainder of 270.
Record the quotient 3 as the next digit in the result. 
Result so far: 129194.935483
Subtract 930 from 1200 to get 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Moving on to step 15:
310 goes into 2700 8 times with a remainder of 220.
The number 8 becomes the next digit in our result. 
Result so far: 129194.9354838
If we subtract 2480 from 2700, we get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Step 16:
310 can be fit into 2200 7 times, resulting in a remainder of 30.
Write down 7 as next digit of the result. 
Result so far: 129194.93548387
Subtract 2170 from 2200 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Our division results in 129194.93548387 with a remaining 3e-08.
