We divide 42157065 by 522
We're looking to find how many times 522 goes into 42157065.

On to step 1:
The number 522 fits into 4 0 times, leaving a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 522

Going ahead to step 2:
The number 522 fits into 42 0 times, leaving a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Take the next digit (1) from the dividend and append it to 42, then repeat: 421 / 522

Moving on to step 3:
If we divide 421 by 522, we get 0 and a remainder of 421.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 421 and we're left with 421.
Grab the next digit (5) from the dividend, add it to 421, then carry on: 4215 / 522

Moving on to step 4:
522 can be fit into 4215 8 times, resulting in a remainder of 39.
The next digit of our result is 8. 
Result so far: 8.0
Subtract 4176 from 4215 to get 39.
Bring next digit (7) of the dividend behind the 39 and repeat the process: 397 / 522

Going ahead to step 5:
If we divide 397 by 522, we get 0 and a remainder of 397.
Write down 0 as next digit of the result. 
Result so far: 80.0
If we subtract 0 from 397, we get 397.
Take the next digit (0) from the dividend and append it to 397, then repeat: 3970 / 522

Moving on to step 6:
3970 divided by 522 is 7 with a remainder of 316.
Put 7 as the next digit of the answer. 
Result so far: 807.0
Subtract 3654 from 3970 to get 316.
Fetch the next digit (6) from the dividend, attach it to 316 and continue: 3166 / 522

On to step 7:
522 can be fit into 3166 6 times, resulting in a remainder of 34.
Put 6 as the next digit of the answer. 
Result so far: 8076.0
Subtracting 3132 from 3166 leaves us with 34.
Bring next digit (5) of the dividend behind the 34 and repeat the process: 345 / 522

Step 8:
345 divided by 522 is 0 with a remainder of 345.
Put 0 as the next digit of the answer. 
Result so far: 80760.0
Subtracting 0 from 345 leaves us with 345.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3450, and continue the process.

Step 9:
3450 divided by 522 is 6 with a remainder of 318.
Use 6 as the next digit of our solution. 
Result so far: 80760.6
Subtracting 3132 from 3450 leaves us with 318.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

Advancing to step 10:
The number 522 fits into 3180 6 times, leaving a remainder of 48.
Record the quotient 6 as the next digit in the result. 
Result so far: 80760.66
The remainder is 48 after subtracting 3132 from 3180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

In conclusion, the division gives 80760.66 with a balance of 0.048.
