Let's divide 859761 by 42
We want to divide 859761 by 42.

Moving on to step 1:
42 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
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

Step 2:
When dividing 85 by 42, we get 2 with a remainder of 1.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 1 after subtracting 84 from 85.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 42

Going ahead to step 3:
If we divide 19 by 42, we get 0 and a remainder of 19.
Put 0 as the next digit of the answer. 
Result so far: 20.0
Subtract 0 from 19 to get 19.
Append the next digit (7) from the dividend to 19 and continue with: 197 / 42

Going ahead to step 4:
197 divided by 42 is 4 with a remainder of 29.
Record the quotient 4 as the next digit in the result. 
Result so far: 204.0
If we subtract 168 from 197, we get 29.
Take the next digit (6) from the dividend and append it to 29, then repeat: 296 / 42

Moving on to step 5:
The number 42 fits into 296 7 times, leaving a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 2047.0
If we subtract 294 from 296, we get 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 42

Moving on to step 6:
If we divide 21 by 42, we get 0 and a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 20470.0
If we take 0 away from 21, 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.

Moving on to step 7:
42 goes into 210 5 times with a remainder of 0.
The next digit of our result is 5. 
Result so far: 20470.5
Deduct 210 from 210 and we're left 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:
0 divided by 42 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 20470.5
Subtract 0 from 0 to 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.

Going ahead to step 9:
The number 42 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 20470.5
Subtract 0 from 0 to 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.

The final outcome is 20470.5, with a leftover of 0.0.
