850063 ÷ 42 
Let's see how many times 42 fits into 850063.

Advancing to step 1:
42 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 42

On to step 2:
85 divided by 42 is 2 with a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 84 away from 85, we end up with 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 42

Advancing to step 3:
10 divided by 42 is 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 20.0
If we take 0 away from 10, we end up with 10.
Grab the next digit (0) from the dividend, add it to 10, then carry on: 100 / 42

Going ahead to step 4:
When dividing 100 by 42, we get 2 with a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 202.0
Subtract 84 from 100 to get 16.
Take the next digit (6) from the dividend and append it to 16, then repeat: 166 / 42

Going ahead to step 5:
42 can be fit into 166 3 times, resulting in a remainder of 40.
The number 3 becomes the next digit in our result. 
Result so far: 2023.0
If we subtract 126 from 166, we get 40.
Include the next digit (3) from the dividend after 40, then repeat: 403 / 42

Moving on to step 6:
When dividing 403 by 42, we get 9 with a remainder of 25.
The next digit of our result is 9. 
Result so far: 20239.0
The remainder is 25 after subtracting 378 from 403.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 7:
250 divided by 42 is 5 with a remainder of 40.
The next digit of our result is 5. 
Result so far: 20239.5
Subtract 210 from 250 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 8:
42 can be fit into 400 9 times, resulting in a remainder of 22.
Record the quotient 9 as the next digit in the result. 
Result so far: 20239.59
The remainder is 22 after subtracting 378 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 9:
220 divided by 42 is 5 with a remainder of 10.
The next digit of our result is 5. 
Result so far: 20239.595
Subtracting 210 from 220 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 10:
The number 42 fits into 100 2 times, leaving a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 20239.5952
If we subtract 84 from 100, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 11:
If we divide 160 by 42, we get 3 and a remainder of 34.
Record the quotient 3 as the next digit in the result. 
Result so far: 20239.59523
The remainder is 34 after subtracting 126 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 12:
42 goes into 340 8 times with a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 20239.595238
Subtract 336 from 340 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 13:
42 goes into 40 0 times with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 20239.595238
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 14:
400 divided by 42 is 9 with a remainder of 22.
Write down 9 as next digit of the result. 
Result so far: 20239.59523809
Subtract 378 from 400 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

The final outcome is 20239.59523809, with a leftover of 2.2e-08.
