78314008 ÷ 42 
Let's see how many times 42 fits into 78314008.

Advancing to step 1:
7 divided by 42 is 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 42

On to step 2:
42 goes into 78 1 times with a remainder of 36.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 42 from 78 leaves us with 36.
Append the next digit (3) from the dividend to 36 and continue with: 363 / 42

Moving on to step 3:
If we divide 363 by 42, we get 8 and a remainder of 27.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
If we subtract 336 from 363, we get 27.
Fetch the next digit (1) from the dividend, attach it to 27 and continue: 271 / 42

Moving on to step 4:
The number 42 fits into 271 6 times, leaving a remainder of 19.
The number 6 becomes the next digit in our result. 
Result so far: 186.0
The remainder is 19 after subtracting 252 from 271.
Fetch the next digit (4) from the dividend, attach it to 19 and continue: 194 / 42

Let's proceed to step 5:
42 goes into 194 4 times with a remainder of 26.
The number 4 becomes the next digit in our result. 
Result so far: 1864.0
The remainder is 26 after subtracting 168 from 194.
Include the next digit (0) from the dividend after 26, then repeat: 260 / 42

Going ahead to step 6:
If we divide 260 by 42, we get 6 and a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 18646.0
If we subtract 252 from 260, we get 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 42

Advancing to step 7:
When dividing 80 by 42, we get 1 with a remainder of 38.
Write down 1 as next digit of the result. 
Result so far: 186461.0
Subtract 42 from 80 to get 38.
Grab the next digit (8) from the dividend, add it to 38, then carry on: 388 / 42

Moving on to step 8:
When dividing 388 by 42, we get 9 with a remainder of 10.
Put 9 as the next digit of the answer. 
Result so far: 1864619.0
Subtract 378 from 388 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 9:
100 divided by 42 is 2 with a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 1864619.2
Subtract 84 from 100 to 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.

Let's proceed to step 10:
42 goes into 160 3 times with a remainder of 34.
The next digit of our result is 3. 
Result so far: 1864619.23
If we subtract 126 from 160, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 11:
340 divided by 42 is 8 with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 1864619.238
If we take 336 away from 340, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 12:
42 can be fit into 40 0 times, resulting in a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 1864619.238
Deduct 0 from 40 and we're left 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.

Step 13:
When dividing 400 by 42, we get 9 with a remainder of 22.
The number 9 becomes the next digit in our result. 
Result so far: 1864619.23809
Deduct 378 from 400 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 14:
The number 42 fits into 220 5 times, leaving a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 1864619.238095
If we take 210 away from 220, we end up 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.

On to step 15:
42 can be fit into 100 2 times, resulting in a remainder of 16.
The next digit of our result is 2. 
Result so far: 1864619.2380952
If we take 84 away from 100, we end up with 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 16:
If we divide 160 by 42, we get 3 and a remainder of 34.
Write down 3 as next digit of the result. 
Result so far: 1864619.23809523
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.

The final outcome is 1864619.23809523, with a leftover of 3.4e-08.
