Let's divide 770387 by 42
We want to figure out the number of times 770387 can be divided by 42.

Going ahead to step 1:
When dividing 7 by 42, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 42

Advancing to step 2:
When dividing 77 by 42, we get 1 with a remainder of 35.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 42 away from 77, we end up with 35.
Fetch the next digit (0) from the dividend, attach it to 35 and continue: 350 / 42

Let's proceed to step 3:
42 goes into 350 8 times with a remainder of 14.
Write down 8 as next digit of the result. 
Result so far: 18.0
If we subtract 336 from 350, we get 14.
Take the next digit (3) from the dividend and append it to 14, then repeat: 143 / 42

Going ahead to step 4:
The number 42 fits into 143 3 times, leaving a remainder of 17.
Record the quotient 3 as the next digit in the result. 
Result so far: 183.0
Subtracting 126 from 143 leaves us with 17.
Append the next digit (8) from the dividend to 17 and continue with: 178 / 42

Moving on to step 5:
178 divided by 42 is 4 with a remainder of 10.
Record the quotient 4 as the next digit in the result. 
Result so far: 1834.0
If we subtract 168 from 178, we get 10.
Bring next digit (7) of the dividend behind the 10 and repeat the process: 107 / 42

Let's proceed to step 6:
If we divide 107 by 42, we get 2 and a remainder of 23.
The next digit of our result is 2. 
Result so far: 18342.0
If we take 84 away from 107, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 7:
The number 42 fits into 230 5 times, leaving a remainder of 20.
The next digit of our result is 5. 
Result so far: 18342.5
Subtract 210 from 230 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 8:
The number 42 fits into 200 4 times, leaving a remainder of 32.
Put 4 as the next digit of the answer. 
Result so far: 18342.54
Subtracting 168 from 200 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 9:
The number 42 fits into 320 7 times, leaving a remainder of 26.
The next digit of our result is 7. 
Result so far: 18342.547
If we subtract 294 from 320, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 10:
When dividing 260 by 42, we get 6 with a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 18342.5476
Deduct 252 from 260 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 11:
The number 42 fits into 80 1 times, leaving a remainder of 38.
Write down 1 as next digit of the result. 
Result so far: 18342.54761
The remainder is 38 after subtracting 42 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 12:
42 goes into 380 9 times with a remainder of 2.
The next digit of our result is 9. 
Result so far: 18342.547619
Deduct 378 from 380 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 13:
42 goes into 20 0 times with a remainder of 20.
The next digit of our result is 0. 
Result so far: 18342.547619
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 14:
When dividing 200 by 42, we get 4 with a remainder of 32.
Record the quotient 4 as the next digit in the result. 
Result so far: 18342.54761904
If we take 168 away from 200, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

After the division, we end up with 18342.54761904 and a remainder of 3.2e-08.
