788719 divided by 42 
We want to figure out the number of times 788719 can be divided by 42.

Step 1:
42 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 42

Going ahead to step 2:
42 goes into 78 1 times with a remainder of 36.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 42 from 78 to get 36.
Take the next digit (8) from the dividend and append it to 36, then repeat: 368 / 42

Advancing to step 3:
When dividing 368 by 42, we get 8 with a remainder of 32.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
Subtract 336 from 368 to get 32.
Bring next digit (7) of the dividend behind the 32 and repeat the process: 327 / 42

Advancing to step 4:
42 goes into 327 7 times with a remainder of 33.
Use 7 as the next digit of our solution. 
Result so far: 187.0
Subtracting 294 from 327 leaves us with 33.
Fetch the next digit (1) from the dividend, attach it to 33 and continue: 331 / 42

Advancing to step 5:
The number 42 fits into 331 7 times, leaving a remainder of 37.
Use 7 as the next digit of our solution. 
Result so far: 1877.0
Subtracting 294 from 331 leaves us with 37.
Include the next digit (9) from the dividend after 37, then repeat: 379 / 42

On to step 6:
The number 42 fits into 379 9 times, leaving a remainder of 1.
The next digit of our result is 9. 
Result so far: 18779.0
If we take 378 away from 379, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 7:
10 divided by 42 is 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 18779.0
If we take 0 away from 10, 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 8:
The number 42 fits into 100 2 times, leaving a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 18779.02
Subtracting 84 from 100 leaves us 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.

Going ahead to step 9:
42 can be fit into 160 3 times, resulting in a remainder of 34.
Use 3 as the next digit of our solution. 
Result so far: 18779.023
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.

Going ahead to step 10:
If we divide 340 by 42, we get 8 and a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 18779.0238
Deduct 336 from 340 and we're left 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.

Step 11:
42 can be fit into 40 0 times, resulting in a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 18779.0238
Subtracting 0 from 40 leaves us 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.

Advancing to step 12:
When dividing 400 by 42, we get 9 with a remainder of 22.
Use 9 as the next digit of our solution. 
Result so far: 18779.023809
The remainder is 22 after subtracting 378 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 13:
220 divided by 42 is 5 with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 18779.0238095
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.

Step 14:
42 goes into 100 2 times with a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 18779.02380952
If we subtract 84 from 100, we 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.

The final outcome is 18779.02380952, with a leftover of 1.6e-08.
