We're dividing 801786 by 42 
Our goal is to divide 801786 by 42.

Going ahead to step 1:
When dividing 8 by 42, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 42

On to step 2:
42 can be fit into 80 1 times, resulting in a remainder of 38.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 42 away from 80, we end up with 38.
Grab the next digit (1) from the dividend, add it to 38, then carry on: 381 / 42

Let's proceed to step 3:
381 divided by 42 is 9 with a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 19.0
Subtract 378 from 381 to get 3.
Include the next digit (7) from the dividend after 3, then repeat: 37 / 42

Moving on to step 4:
37 divided by 42 is 0 with a remainder of 37.
The next digit of our result is 0. 
Result so far: 190.0
Subtract 0 from 37 to get 37.
Include the next digit (8) from the dividend after 37, then repeat: 378 / 42

Advancing to step 5:
378 divided by 42 is 9 with a remainder of 0.
Use 9 as the next digit of our solution. 
Result so far: 1909.0
If we subtract 378 from 378, we get 0.
Append the next digit (6) from the dividend to 0 and continue with: 6 / 42

Let's proceed to step 6:
The number 42 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 19090.0
The remainder is 6 after subtracting 0 from 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 7:
If we divide 60 by 42, we get 1 and a remainder of 18.
The number 1 becomes the next digit in our result. 
Result so far: 19090.1
Subtracting 42 from 60 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 8:
180 divided by 42 is 4 with a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 19090.14
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.

Going ahead to step 9:
If we divide 120 by 42, we get 2 and a remainder of 36.
Put 2 as the next digit of the answer. 
Result so far: 19090.142
If we take 84 away from 120, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 10:
The number 42 fits into 360 8 times, leaving a remainder of 24.
Write down 8 as next digit of the result. 
Result so far: 19090.1428
Deduct 336 from 360 and we're left 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.

Advancing to step 11:
The number 42 fits into 240 5 times, leaving a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 19090.14285
If we subtract 210 from 240, we 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.

On to step 12:
300 divided by 42 is 7 with a remainder of 6.
Use 7 as the next digit of our solution. 
Result so far: 19090.142857
Subtract 294 from 300 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 13:
60 divided by 42 is 1 with a remainder of 18.
The next digit of our result is 1. 
Result so far: 19090.1428571
If we take 42 away from 60, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 14:
When dividing 180 by 42, we get 4 with a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 19090.14285714
The remainder is 12 after subtracting 168 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final result is 19090.14285714 with a remainder of 1.2e-08.
