We look at the division of 787819 by 42 
We want to figure out the number of times 787819 can be divided by 42.

Moving on to step 1:
42 goes into 7 0 times with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 42

Step 2:
If we divide 78 by 42, we get 1 and a remainder of 36.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 42 from 78 and we're left with 36.
Take the next digit (7) from the dividend and append it to 36, then repeat: 367 / 42

On to step 3:
42 can be fit into 367 8 times, resulting in a remainder of 31.
Put 8 as the next digit of the answer. 
Result so far: 18.0
If we subtract 336 from 367, we get 31.
Grab the next digit (8) from the dividend, add it to 31, then carry on: 318 / 42

Advancing to step 4:
The number 42 fits into 318 7 times, leaving a remainder of 24.
The number 7 becomes the next digit in our result. 
Result so far: 187.0
If we subtract 294 from 318, we get 24.
Include the next digit (1) from the dividend after 24, then repeat: 241 / 42

On to step 5:
42 can be fit into 241 5 times, resulting in a remainder of 31.
Put 5 as the next digit of the answer. 
Result so far: 1875.0
Deduct 210 from 241 and we're left with 31.
Append the next digit (9) from the dividend to 31 and continue with: 319 / 42

Let's proceed to step 6:
If we divide 319 by 42, we get 7 and a remainder of 25.
The next digit of our result is 7. 
Result so far: 18757.0
Deduct 294 from 319 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 7:
If we divide 250 by 42, we get 5 and a remainder of 40.
The number 5 becomes the next digit in our result. 
Result so far: 18757.5
The remainder is 40 after subtracting 210 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 8:
42 can be fit into 400 9 times, resulting in a remainder of 22.
The number 9 becomes the next digit in our result. 
Result so far: 18757.59
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.

Step 9:
42 goes into 220 5 times with a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 18757.595
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.

Advancing to step 10:
When dividing 100 by 42, we get 2 with a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 18757.5952
Deduct 84 from 100 and we're left 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.

On to step 11:
When dividing 160 by 42, we get 3 with a remainder of 34.
The number 3 becomes the next digit in our result. 
Result so far: 18757.59523
Subtracting 126 from 160 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 12:
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: 18757.595238
Subtract 336 from 340 to get 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 13:
42 can be fit into 40 0 times, resulting in a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 18757.595238
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.

Moving on to step 14:
The number 42 fits into 400 9 times, leaving a remainder of 22.
The number 9 becomes the next digit in our result. 
Result so far: 18757.59523809
Subtracting 378 from 400 leaves us 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.

In conclusion, the division gives 18757.59523809 with a balance of 2.2e-08.
