We're dividing 38124580 by 343 
We want to figure out the number of times 38124580 can be divided by 343.

Advancing to step 1:
The number 343 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Take the next digit (8) from the dividend and append it to 3, then repeat: 38 / 343

Let's proceed to step 2:
343 goes into 38 0 times with a remainder of 38.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 38 after subtracting 0 from 38.
Grab the next digit (1) from the dividend, add it to 38, then carry on: 381 / 343

Step 3:
381 divided by 343 is 1 with a remainder of 38.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 343 from 381, we get 38.
Take the next digit (2) from the dividend and append it to 38, then repeat: 382 / 343

Advancing to step 4:
The number 343 fits into 382 1 times, leaving a remainder of 39.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Subtracting 343 from 382 leaves us with 39.
Take the next digit (4) from the dividend and append it to 39, then repeat: 394 / 343

Step 5:
343 can be fit into 394 1 times, resulting in a remainder of 51.
The number 1 becomes the next digit in our result. 
Result so far: 111.0
Subtract 343 from 394 to get 51.
Fetch the next digit (5) from the dividend, attach it to 51 and continue: 515 / 343

Going ahead to step 6:
515 divided by 343 is 1 with a remainder of 172.
Put 1 as the next digit of the answer. 
Result so far: 1111.0
Deduct 343 from 515 and we're left with 172.
Bring next digit (8) of the dividend behind the 172 and repeat the process: 1728 / 343

On to step 7:
If we divide 1728 by 343, we get 5 and a remainder of 13.
The number 5 becomes the next digit in our result. 
Result so far: 11115.0
The remainder is 13 after subtracting 1715 from 1728.
Grab the next digit (0) from the dividend, add it to 13, then carry on: 130 / 343

On to step 8:
130 divided by 343 is 0 with a remainder of 130.
The next digit of our result is 0. 
Result so far: 111150.0
If we subtract 0 from 130, we get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Going ahead to step 9:
The number 343 fits into 1300 3 times, leaving a remainder of 271.
The number 3 becomes the next digit in our result. 
Result so far: 111150.3
If we take 1029 away from 1300, we end up with 271.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2710, and continue the process.

On to step 10:
When dividing 2710 by 343, we get 7 with a remainder of 309.
The number 7 becomes the next digit in our result. 
Result so far: 111150.37
Subtract 2401 from 2710 to get 309.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3090, and continue the process.

Let's proceed to step 11:
If we divide 3090 by 343, we get 9 and a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 111150.379
Subtract 3087 from 3090 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 12:
When dividing 30 by 343, we get 0 with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 111150.379
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 13:
343 can be fit into 300 0 times, resulting in a remainder of 300.
The number 0 becomes the next digit in our result. 
Result so far: 111150.379
Subtracting 0 from 300 leaves us with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

After the division, we end up with 111150.379 and a remainder of 0.0003.
