12570343 ÷ 744 
We're looking to find how many times 744 goes into 12570343.

Let's proceed to step 1:
744 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 744

On to step 2:
When dividing 12 by 744, we get 0 with a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Grab the next digit (5) from the dividend, add it to 12, then carry on: 125 / 744

Let's proceed to step 3:
If we divide 125 by 744, we get 0 and a remainder of 125.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 125 after subtracting 0 from 125.
Take the next digit (7) from the dividend and append it to 125, then repeat: 1257 / 744

Advancing to step 4:
If we divide 1257 by 744, we get 1 and a remainder of 513.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 513 after subtracting 744 from 1257.
Bring next digit (0) of the dividend behind the 513 and repeat the process: 5130 / 744

On to step 5:
When dividing 5130 by 744, we get 6 with a remainder of 666.
Write down 6 as next digit of the result. 
Result so far: 16.0
Deduct 4464 from 5130 and we're left with 666.
Include the next digit (3) from the dividend after 666, then repeat: 6663 / 744

Let's proceed to step 6:
The number 744 fits into 6663 8 times, leaving a remainder of 711.
The next digit of our result is 8. 
Result so far: 168.0
The remainder is 711 after subtracting 5952 from 6663.
Grab the next digit (4) from the dividend, add it to 711, then carry on: 7114 / 744

Step 7:
If we divide 7114 by 744, we get 9 and a remainder of 418.
Use 9 as the next digit of our solution. 
Result so far: 1689.0
Deduct 6696 from 7114 and we're left with 418.
Fetch the next digit (3) from the dividend, attach it to 418 and continue: 4183 / 744

On to step 8:
744 can be fit into 4183 5 times, resulting in a remainder of 463.
The number 5 becomes the next digit in our result. 
Result so far: 16895.0
If we subtract 3720 from 4183, we get 463.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4630, and continue the process.

Step 9:
744 goes into 4630 6 times with a remainder of 166.
The number 6 becomes the next digit in our result. 
Result so far: 16895.6
If we take 4464 away from 4630, we end up with 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Let's proceed to step 10:
744 goes into 1660 2 times with a remainder of 172.
Use 2 as the next digit of our solution. 
Result so far: 16895.62
Subtract 1488 from 1660 to get 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Moving on to step 11:
744 can be fit into 1720 2 times, resulting in a remainder of 232.
Use 2 as the next digit of our solution. 
Result so far: 16895.622
The remainder is 232 after subtracting 1488 from 1720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

After the division, we end up with 16895.622 and a remainder of 0.0232.
