778199 ÷ 42 
Our goal is to divide 778199 by 42.

On to step 1:
7 divided by 42 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 42

Step 2:
42 can be fit into 77 1 times, resulting in a remainder of 35.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 35 after subtracting 42 from 77.
Fetch the next digit (8) from the dividend, attach it to 35 and continue: 358 / 42

On to step 3:
If we divide 358 by 42, we get 8 and a remainder of 22.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
The remainder is 22 after subtracting 336 from 358.
Include the next digit (1) from the dividend after 22, then repeat: 221 / 42

On to step 4:
When dividing 221 by 42, we get 5 with a remainder of 11.
Write down 5 as next digit of the result. 
Result so far: 185.0
Deduct 210 from 221 and we're left with 11.
Bring next digit (9) of the dividend behind the 11 and repeat the process: 119 / 42

Step 5:
42 can be fit into 119 2 times, resulting in a remainder of 35.
Record the quotient 2 as the next digit in the result. 
Result so far: 1852.0
If we take 84 away from 119, we end up with 35.
Append the next digit (9) from the dividend to 35 and continue with: 359 / 42

Advancing to step 6:
42 can be fit into 359 8 times, resulting in a remainder of 23.
Use 8 as the next digit of our solution. 
Result so far: 18528.0
If we subtract 336 from 359, we get 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 number 5 becomes the next digit in our result. 
Result so far: 18528.5
Deduct 210 from 230 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 8:
If we divide 200 by 42, we get 4 and a remainder of 32.
Use 4 as the next digit of our solution. 
Result so far: 18528.54
Subtract 168 from 200 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 9:
42 can be fit into 320 7 times, resulting in a remainder of 26.
The next digit of our result is 7. 
Result so far: 18528.547
Deduct 294 from 320 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 10:
42 can be fit into 260 6 times, resulting in a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 18528.5476
If we subtract 252 from 260, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 11:
If we divide 80 by 42, we get 1 and a remainder of 38.
The number 1 becomes the next digit in our result. 
Result so far: 18528.54761
Deduct 42 from 80 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 12:
380 divided by 42 is 9 with a remainder of 2.
Put 9 as the next digit of the answer. 
Result so far: 18528.547619
If we take 378 away from 380, we end up 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.

Let's proceed to step 13:
20 divided by 42 is 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 18528.547619
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 14:
42 can be fit into 200 4 times, resulting in a remainder of 32.
Use 4 as the next digit of our solution. 
Result so far: 18528.54761904
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.

The final outcome is 18528.54761904, with a leftover of 3.2e-08.
