We divide 779583 by 42
We want to figure out the number of times 779583 can be divided by 42.

Advancing to step 1:
The number 42 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 42

On to step 2:
The number 42 fits into 77 1 times, leaving a remainder of 35.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 42 from 77 to get 35.
Fetch the next digit (9) from the dividend, attach it to 35 and continue: 359 / 42

Advancing to step 3:
42 can be fit into 359 8 times, resulting in a remainder of 23.
Put 8 as the next digit of the answer. 
Result so far: 18.0
Deduct 336 from 359 and we're left with 23.
Fetch the next digit (5) from the dividend, attach it to 23 and continue: 235 / 42

Advancing to step 4:
If we divide 235 by 42, we get 5 and a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 185.0
Subtract 210 from 235 to get 25.
Append the next digit (8) from the dividend to 25 and continue with: 258 / 42

Advancing to step 5:
42 goes into 258 6 times with a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 1856.0
Subtract 252 from 258 to get 6.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 42

On to step 6:
42 can be fit into 63 1 times, resulting in a remainder of 21.
Write down 1 as next digit of the result. 
Result so far: 18561.0
If we take 42 away from 63, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 7:
210 divided by 42 is 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 18561.5
If we take 210 away from 210, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 8:
When dividing 0 by 42, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 18561.5
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 9:
42 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 18561.5
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 18561.5 and a remainder of 0.0.
