We look at the division of 43857120 by 497 
We're looking to find how many times 497 goes into 43857120.

Advancing to step 1:
497 can be fit into 4 0 times, resulting in a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 497

Moving on to step 2:
497 goes into 43 0 times with a remainder of 43.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 43 leaves us with 43.
Take the next digit (8) from the dividend and append it to 43, then repeat: 438 / 497

Let's proceed to step 3:
497 can be fit into 438 0 times, resulting in a remainder of 438.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 438 and we're left with 438.
Append the next digit (5) from the dividend to 438 and continue with: 4385 / 497

On to step 4:
4385 divided by 497 is 8 with a remainder of 409.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we subtract 3976 from 4385, we get 409.
Grab the next digit (7) from the dividend, add it to 409, then carry on: 4097 / 497

Going ahead to step 5:
497 goes into 4097 8 times with a remainder of 121.
Record the quotient 8 as the next digit in the result. 
Result so far: 88.0
If we take 3976 away from 4097, we end up with 121.
Bring next digit (1) of the dividend behind the 121 and repeat the process: 1211 / 497

Step 6:
1211 divided by 497 is 2 with a remainder of 217.
Put 2 as the next digit of the answer. 
Result so far: 882.0
If we take 994 away from 1211, we end up with 217.
Grab the next digit (2) from the dividend, add it to 217, then carry on: 2172 / 497

Let's proceed to step 7:
If we divide 2172 by 497, we get 4 and a remainder of 184.
Use 4 as the next digit of our solution. 
Result so far: 8824.0
Subtracting 1988 from 2172 leaves us with 184.
Grab the next digit (0) from the dividend, add it to 184, then carry on: 1840 / 497

Let's proceed to step 8:
If we divide 1840 by 497, we get 3 and a remainder of 349.
Put 3 as the next digit of the answer. 
Result so far: 88243.0
Subtract 1491 from 1840 to get 349.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3490, and continue the process.

Step 9:
The number 497 fits into 3490 7 times, leaving a remainder of 11.
The next digit of our result is 7. 
Result so far: 88243.7
The remainder is 11 after subtracting 3479 from 3490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 10:
110 divided by 497 is 0 with a remainder of 110.
Record the quotient 0 as the next digit in the result. 
Result so far: 88243.7
Deduct 0 from 110 and we're left with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Going ahead to step 11:
497 can be fit into 1100 2 times, resulting in a remainder of 106.
Record the quotient 2 as the next digit in the result. 
Result so far: 88243.702
If we subtract 994 from 1100, we get 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Moving on to step 12:
497 can be fit into 1060 2 times, resulting in a remainder of 66.
Use 2 as the next digit of our solution. 
Result so far: 88243.7022
The remainder is 66 after subtracting 994 from 1060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

The final outcome is 88243.7022, with a leftover of 0.00066.
