We're dividing 811707 by 42 
Let's see how many times 42 fits into 811707.

Advancing to step 1:
The number 42 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 42

On to step 2:
42 goes into 81 1 times with a remainder of 39.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 42 away from 81, we end up with 39.
Take the next digit (1) from the dividend and append it to 39, then repeat: 391 / 42

Going ahead to step 3:
When dividing 391 by 42, we get 9 with a remainder of 13.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
Deduct 378 from 391 and we're left with 13.
Bring next digit (7) of the dividend behind the 13 and repeat the process: 137 / 42

Advancing to step 4:
42 goes into 137 3 times with a remainder of 11.
Put 3 as the next digit of the answer. 
Result so far: 193.0
If we take 126 away from 137, we end up with 11.
Append the next digit (0) from the dividend to 11 and continue with: 110 / 42

Going ahead to step 5:
42 can be fit into 110 2 times, resulting in a remainder of 26.
The number 2 becomes the next digit in our result. 
Result so far: 1932.0
Subtract 84 from 110 to get 26.
Append the next digit (7) from the dividend to 26 and continue with: 267 / 42

Step 6:
42 can be fit into 267 6 times, resulting in a remainder of 15.
The number 6 becomes the next digit in our result. 
Result so far: 19326.0
Subtracting 252 from 267 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 7:
When dividing 150 by 42, we get 3 with a remainder of 24.
Record the quotient 3 as the next digit in the result. 
Result so far: 19326.3
The remainder is 24 after subtracting 126 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 8:
240 divided by 42 is 5 with a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 19326.35
If we take 210 away from 240, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 9:
300 divided by 42 is 7 with a remainder of 6.
The next digit of our result is 7. 
Result so far: 19326.357
The remainder is 6 after subtracting 294 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 10:
42 can be fit into 60 1 times, resulting in a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 19326.3571
Subtract 42 from 60 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 11:
42 goes into 180 4 times with a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 19326.35714
If we take 168 away from 180, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 12:
42 can be fit into 120 2 times, resulting in a remainder of 36.
The number 2 becomes the next digit in our result. 
Result so far: 19326.357142
Subtract 84 from 120 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 13:
When dividing 360 by 42, we get 8 with a remainder of 24.
The number 8 becomes the next digit in our result. 
Result so far: 19326.3571428
Subtracting 336 from 360 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 14:
240 divided by 42 is 5 with a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 19326.35714285
Subtract 210 from 240 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

In conclusion, the division gives 19326.35714285 with a balance of 3e-08.
