We're dividing 42985 by 522 
We want to divide 42985 by 522.

Step 1:
When dividing 4 by 522, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 522

Moving on to step 2:
The number 522 fits into 42 0 times, leaving a remainder of 42.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 42 and we're left with 42.
Grab the next digit (9) from the dividend, add it to 42, then carry on: 429 / 522

Step 3:
522 goes into 429 0 times with a remainder of 429.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 429 leaves us with 429.
Bring next digit (8) of the dividend behind the 429 and repeat the process: 4298 / 522

Step 4:
4298 divided by 522 is 8 with a remainder of 122.
Write down 8 as next digit of the result. 
Result so far: 8.0
The remainder is 122 after subtracting 4176 from 4298.
Grab the next digit (5) from the dividend, add it to 122, then carry on: 1225 / 522

Advancing to step 5:
522 goes into 1225 2 times with a remainder of 181.
Record the quotient 2 as the next digit in the result. 
Result so far: 82.0
Deduct 1044 from 1225 and we're left with 181.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

On to step 6:
1810 divided by 522 is 3 with a remainder of 244.
The next digit of our result is 3. 
Result so far: 82.3
If we take 1566 away from 1810, we end up with 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

On to step 7:
522 goes into 2440 4 times with a remainder of 352.
Record the quotient 4 as the next digit in the result. 
Result so far: 82.34
Deduct 2088 from 2440 and we're left with 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Going ahead to step 8:
522 goes into 3520 6 times with a remainder of 388.
The number 6 becomes the next digit in our result. 
Result so far: 82.346
Deduct 3132 from 3520 and we're left with 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Let's proceed to step 9:
3880 divided by 522 is 7 with a remainder of 226.
The number 7 becomes the next digit in our result. 
Result so far: 82.3467
Subtract 3654 from 3880 to get 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Let's proceed to step 10:
The number 522 fits into 2260 4 times, leaving a remainder of 172.
Write down 4 as next digit of the result. 
Result so far: 82.34674
If we take 2088 away from 2260, we end up with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

On to step 11:
The number 522 fits into 1720 3 times, leaving a remainder of 154.
The number 3 becomes the next digit in our result. 
Result so far: 82.346743
Subtracting 1566 from 1720 leaves us with 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Advancing to step 12:
1540 divided by 522 is 2 with a remainder of 496.
The number 2 becomes the next digit in our result. 
Result so far: 82.3467432
If we take 1044 away from 1540, we end up with 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

Advancing to step 13:
4960 divided by 522 is 9 with a remainder of 262.
The next digit of our result is 9. 
Result so far: 82.34674329
If we take 4698 away from 4960, we end up with 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

The final outcome is 82.34674329, with a leftover of 2.62e-07.
