819740 divided by 42 
Our goal is to divide 819740 by 42.

Advancing to step 1:
If we divide 8 by 42, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 42

Step 2:
When dividing 81 by 42, we get 1 with a remainder of 39.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 42 from 81, we get 39.
Fetch the next digit (9) from the dividend, attach it to 39 and continue: 399 / 42

On to step 3:
42 can be fit into 399 9 times, resulting in a remainder of 21.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
Subtracting 378 from 399 leaves us with 21.
Bring next digit (7) of the dividend behind the 21 and repeat the process: 217 / 42

Going ahead to step 4:
The number 42 fits into 217 5 times, leaving a remainder of 7.
The number 5 becomes the next digit in our result. 
Result so far: 195.0
If we subtract 210 from 217, we get 7.
Append the next digit (4) from the dividend to 7 and continue with: 74 / 42

On to step 5:
42 can be fit into 74 1 times, resulting in a remainder of 32.
Record the quotient 1 as the next digit in the result. 
Result so far: 1951.0
Subtracting 42 from 74 leaves us with 32.
Fetch the next digit (0) from the dividend, attach it to 32 and continue: 320 / 42

On to step 6:
42 can be fit into 320 7 times, resulting in a remainder of 26.
Use 7 as the next digit of our solution. 
Result so far: 19517.0
If we subtract 294 from 320, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 7:
When dividing 260 by 42, we get 6 with a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 19517.6
If we take 252 away from 260, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 8:
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: 19517.61
Subtract 42 from 80 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 9:
When dividing 380 by 42, we get 9 with a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 19517.619
Subtracting 378 from 380 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 10:
20 divided by 42 is 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 19517.619
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 11:
The number 42 fits into 200 4 times, leaving a remainder of 32.
Record the quotient 4 as the next digit in the result. 
Result so far: 19517.61904
The remainder is 32 after subtracting 168 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 12:
The number 42 fits into 320 7 times, leaving a remainder of 26.
Record the quotient 7 as the next digit in the result. 
Result so far: 19517.619047
Subtracting 294 from 320 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 13:
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: 19517.6190476
The remainder is 8 after subtracting 252 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 14:
When dividing 80 by 42, we get 1 with a remainder of 38.
Use 1 as the next digit of our solution. 
Result so far: 19517.61904761
If we subtract 42 from 80, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Our division results in 19517.61904761 with a remaining 3.8e-08.
