57508517 ÷ 743 
We want to figure out the number of times 57508517 can be divided by 743.

Going ahead to step 1:
743 goes into 5 0 times with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Fetch the next digit (7) from the dividend, attach it to 5 and continue: 57 / 743

Step 2:
When dividing 57 by 743, we get 0 with a remainder of 57.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 57 and we're left with 57.
Grab the next digit (5) from the dividend, add it to 57, then carry on: 575 / 743

Moving on to step 3:
743 can be fit into 575 0 times, resulting in a remainder of 575.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 575 and we're left with 575.
Append the next digit (0) from the dividend to 575 and continue with: 5750 / 743

Step 4:
The number 743 fits into 5750 7 times, leaving a remainder of 549.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Deduct 5201 from 5750 and we're left with 549.
Bring next digit (8) of the dividend behind the 549 and repeat the process: 5498 / 743

Going ahead to step 5:
5498 divided by 743 is 7 with a remainder of 297.
Put 7 as the next digit of the answer. 
Result so far: 77.0
Deduct 5201 from 5498 and we're left with 297.
Include the next digit (5) from the dividend after 297, then repeat: 2975 / 743

Going ahead to step 6:
743 goes into 2975 4 times with a remainder of 3.
The next digit of our result is 4. 
Result so far: 774.0
If we take 2972 away from 2975, we end up with 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 743

Going ahead to step 7:
If we divide 31 by 743, we get 0 and a remainder of 31.
The next digit of our result is 0. 
Result so far: 7740.0
Subtract 0 from 31 to get 31.
Take the next digit (7) from the dividend and append it to 31, then repeat: 317 / 743

On to step 8:
743 can be fit into 317 0 times, resulting in a remainder of 317.
Use 0 as the next digit of our solution. 
Result so far: 77400.0
If we take 0 away from 317, we end up with 317.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3170, and continue the process.

Advancing to step 9:
743 can be fit into 3170 4 times, resulting in a remainder of 198.
Put 4 as the next digit of the answer. 
Result so far: 77400.4
The remainder is 198 after subtracting 2972 from 3170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Step 10:
743 can be fit into 1980 2 times, resulting in a remainder of 494.
Put 2 as the next digit of the answer. 
Result so far: 77400.42
Subtract 1486 from 1980 to get 494.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4940, and continue the process.

Step 11:
When dividing 4940 by 743, we get 6 with a remainder of 482.
Put 6 as the next digit of the answer. 
Result so far: 77400.426
Subtracting 4458 from 4940 leaves us with 482.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4820, and continue the process.

Going ahead to step 12:
743 goes into 4820 6 times with a remainder of 362.
The number 6 becomes the next digit in our result. 
Result so far: 77400.4266
If we take 4458 away from 4820, we end up with 362.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

The final result is 77400.4266 with a remainder of 0.00362.
