57146557 ÷ 43 
We want to figure out the number of times 57146557 can be divided by 43.

Moving on to step 1:
If we divide 5 by 43, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Fetch the next digit (7) from the dividend, attach it to 5 and continue: 57 / 43

Moving on to step 2:
The number 43 fits into 57 1 times, leaving a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 43 from 57 and we're left with 14.
Fetch the next digit (1) from the dividend, attach it to 14 and continue: 141 / 43

Going ahead to step 3:
If we divide 141 by 43, we get 3 and a remainder of 12.
Put 3 as the next digit of the answer. 
Result so far: 13.0
If we take 129 away from 141, we end up with 12.
Fetch the next digit (4) from the dividend, attach it to 12 and continue: 124 / 43

Going ahead to step 4:
The number 43 fits into 124 2 times, leaving a remainder of 38.
The next digit of our result is 2. 
Result so far: 132.0
Subtracting 86 from 124 leaves us with 38.
Take the next digit (6) from the dividend and append it to 38, then repeat: 386 / 43

Step 5:
43 can be fit into 386 8 times, resulting in a remainder of 42.
Put 8 as the next digit of the answer. 
Result so far: 1328.0
If we subtract 344 from 386, we get 42.
Bring next digit (5) of the dividend behind the 42 and repeat the process: 425 / 43

Step 6:
425 divided by 43 is 9 with a remainder of 38.
Write down 9 as next digit of the result. 
Result so far: 13289.0
If we subtract 387 from 425, we get 38.
Append the next digit (5) from the dividend to 38 and continue with: 385 / 43

Moving on to step 7:
When dividing 385 by 43, we get 8 with a remainder of 41.
The next digit of our result is 8. 
Result so far: 132898.0
Subtract 344 from 385 to get 41.
Append the next digit (7) from the dividend to 41 and continue with: 417 / 43

Moving on to step 8:
When dividing 417 by 43, we get 9 with a remainder of 30.
The number 9 becomes the next digit in our result. 
Result so far: 1328989.0
The remainder is 30 after subtracting 387 from 417.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 9:
If we divide 300 by 43, we get 6 and a remainder of 42.
The number 6 becomes the next digit in our result. 
Result so far: 1328989.6
Subtract 258 from 300 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 10:
43 can be fit into 420 9 times, resulting in a remainder of 33.
The next digit of our result is 9. 
Result so far: 1328989.69
Subtracting 387 from 420 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Let's proceed to step 11:
43 goes into 330 7 times with a remainder of 29.
The next digit of our result is 7. 
Result so far: 1328989.697
Subtract 301 from 330 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 12:
43 can be fit into 290 6 times, resulting in a remainder of 32.
Use 6 as the next digit of our solution. 
Result so far: 1328989.6976
Subtract 258 from 290 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 13:
43 can be fit into 320 7 times, resulting in a remainder of 19.
Record the quotient 7 as the next digit in the result. 
Result so far: 1328989.69767
If we take 301 away from 320, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 14:
The number 43 fits into 190 4 times, leaving a remainder of 18.
Put 4 as the next digit of the answer. 
Result so far: 1328989.697674
If we take 172 away from 190, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 15:
If we divide 180 by 43, we get 4 and a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 1328989.6976744
Deduct 172 from 180 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The quotient of the division is 1328989.6976744, and the remainder is 8e-08.
