Let's divide 42945394 by 497
We're looking to find how many times 497 goes into 42945394.

Advancing to step 1:
4 divided by 497 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 497

Step 2:
If we divide 42 by 497, we get 0 and a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 42 to get 42.
Append the next digit (9) from the dividend to 42 and continue with: 429 / 497

Advancing to step 3:
429 divided by 497 is 0 with a remainder of 429.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 429 to get 429.
Append the next digit (4) from the dividend to 429 and continue with: 4294 / 497

On to step 4:
The number 497 fits into 4294 8 times, leaving a remainder of 318.
The next digit of our result is 8. 
Result so far: 8.0
Subtracting 3976 from 4294 leaves us with 318.
Grab the next digit (5) from the dividend, add it to 318, then carry on: 3185 / 497

Advancing to step 5:
3185 divided by 497 is 6 with a remainder of 203.
Record the quotient 6 as the next digit in the result. 
Result so far: 86.0
If we take 2982 away from 3185, we end up with 203.
Grab the next digit (3) from the dividend, add it to 203, then carry on: 2033 / 497

On to step 6:
497 can be fit into 2033 4 times, resulting in a remainder of 45.
The number 4 becomes the next digit in our result. 
Result so far: 864.0
The remainder is 45 after subtracting 1988 from 2033.
Include the next digit (9) from the dividend after 45, then repeat: 459 / 497

Step 7:
When dividing 459 by 497, we get 0 with a remainder of 459.
Record the quotient 0 as the next digit in the result. 
Result so far: 8640.0
Deduct 0 from 459 and we're left with 459.
Take the next digit (4) from the dividend and append it to 459, then repeat: 4594 / 497

On to step 8:
497 can be fit into 4594 9 times, resulting in a remainder of 121.
Put 9 as the next digit of the answer. 
Result so far: 86409.0
If we take 4473 away from 4594, we end up with 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Step 9:
The number 497 fits into 1210 2 times, leaving a remainder of 216.
Put 2 as the next digit of the answer. 
Result so far: 86409.2
Subtracting 994 from 1210 leaves us with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Let's proceed to step 10:
497 goes into 2160 4 times with a remainder of 172.
Record the quotient 4 as the next digit in the result. 
Result so far: 86409.24
The remainder is 172 after subtracting 1988 from 2160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Going ahead to step 11:
If we divide 1720 by 497, we get 3 and a remainder of 229.
Put 3 as the next digit of the answer. 
Result so far: 86409.243
The remainder is 229 after subtracting 1491 from 1720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2290, and continue the process.

Going ahead to step 12:
2290 divided by 497 is 4 with a remainder of 302.
Record the quotient 4 as the next digit in the result. 
Result so far: 86409.2434
If we subtract 1988 from 2290, we get 302.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

Step 13:
When dividing 3020 by 497, we get 6 with a remainder of 38.
Use 6 as the next digit of our solution. 
Result so far: 86409.24346
Subtract 2982 from 3020 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 14:
If we divide 380 by 497, we get 0 and a remainder of 380.
The next digit of our result is 0. 
Result so far: 86409.24346
Subtract 0 from 380 to get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

On to step 15:
497 goes into 3800 7 times with a remainder of 321.
The next digit of our result is 7. 
Result so far: 86409.2434607
The remainder is 321 after subtracting 3479 from 3800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3210, and continue the process.

Moving on to step 16:
If we divide 3210 by 497, we get 6 and a remainder of 228.
The number 6 becomes the next digit in our result. 
Result so far: 86409.24346076
If we take 2982 away from 3210, we end up with 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

The final result is 86409.24346076 with a remainder of 2.28e-07.
