819844 divided by 42 
We want to divide 819844 by 42.

On 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
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 42

Going ahead to step 2:
81 divided by 42 is 1 with a remainder of 39.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 42 from 81, we get 39.
Take the next digit (9) from the dividend and append it to 39, then repeat: 399 / 42

Going ahead to step 3:
42 can be fit into 399 9 times, resulting in a remainder of 21.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
If we take 378 away from 399, we end up with 21.
Grab the next digit (8) from the dividend, add it to 21, then carry on: 218 / 42

Going ahead to step 4:
42 can be fit into 218 5 times, resulting in a remainder of 8.
Put 5 as the next digit of the answer. 
Result so far: 195.0
If we take 210 away from 218, we end up with 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 42

Moving on to step 5:
If we divide 84 by 42, we get 2 and a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 1952.0
Deduct 84 from 84 and we're left with 0.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 42

Let's proceed to step 6:
The number 42 fits into 4 0 times, leaving a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 19520.0
Deduct 0 from 4 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.

Let's proceed to step 7:
40 divided by 42 is 0 with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 19520.0
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 8:
The number 42 fits into 400 9 times, leaving a remainder of 22.
Record the quotient 9 as the next digit in the result. 
Result so far: 19520.09
If we take 378 away from 400, we end up 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.

Advancing to step 9:
The number 42 fits into 220 5 times, leaving a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 19520.095
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.

Going ahead to step 10:
If we divide 100 by 42, we get 2 and a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 19520.0952
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.

On to step 11:
The number 42 fits into 160 3 times, leaving a remainder of 34.
Record the quotient 3 as the next digit in the result. 
Result so far: 19520.09523
Deduct 126 from 160 and we're left 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.

Going ahead to step 12:
When dividing 340 by 42, we get 8 with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 19520.095238
The remainder is 4 after subtracting 336 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 13:
40 divided by 42 is 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 19520.095238
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.

On to step 14:
The number 42 fits into 400 9 times, leaving a remainder of 22.
Put 9 as the next digit of the answer. 
Result so far: 19520.09523809
If we subtract 378 from 400, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Our division results in 19520.09523809 with a remaining 2.2e-08.
