We look at the division of 843468 by 42 
We want to divide 843468 by 42.

Advancing to step 1:
42 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 42

Let's proceed to step 2:
The number 42 fits into 84 2 times, leaving a remainder of 0.
The next digit of our result is 2. 
Result so far: 2.0
If we take 84 away from 84, we end up with 0.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 42

Going ahead to step 3:
The number 42 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (4) from the dividend, attach it to 3 and continue: 34 / 42

Let's proceed to step 4:
When dividing 34 by 42, we get 0 with a remainder of 34.
Write down 0 as next digit of the result. 
Result so far: 200.0
If we take 0 away from 34, we end up with 34.
Fetch the next digit (6) from the dividend, attach it to 34 and continue: 346 / 42

Moving on to step 5:
42 goes into 346 8 times with a remainder of 10.
Put 8 as the next digit of the answer. 
Result so far: 2008.0
Subtract 336 from 346 to get 10.
Take the next digit (8) from the dividend and append it to 10, then repeat: 108 / 42

On to step 6:
When dividing 108 by 42, we get 2 with a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 20082.0
Deduct 84 from 108 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.

On to step 7:
If we divide 240 by 42, we get 5 and a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 20082.5
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.

On to step 8:
If we divide 300 by 42, we get 7 and a remainder of 6.
Put 7 as the next digit of the answer. 
Result so far: 20082.57
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.

Advancing to step 9:
42 can be fit into 60 1 times, resulting in a remainder of 18.
Use 1 as the next digit of our solution. 
Result so far: 20082.571
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.

Advancing to step 10:
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: 20082.5714
Deduct 168 from 180 and we're left 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.

Let's proceed to step 11:
If we divide 120 by 42, we get 2 and a remainder of 36.
Record the quotient 2 as the next digit in the result. 
Result so far: 20082.57142
Deduct 84 from 120 and we're left 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 12:
When dividing 360 by 42, we get 8 with a remainder of 24.
Put 8 as the next digit of the answer. 
Result so far: 20082.571428
If we take 336 away from 360, we end up 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.

On to step 13:
When dividing 240 by 42, we get 5 with a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 20082.5714285
The remainder is 30 after subtracting 210 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 14:
42 goes into 300 7 times with a remainder of 6.
Use 7 as the next digit of our solution. 
Result so far: 20082.57142857
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.

After the division, we end up with 20082.57142857 and a remainder of 6e-09.
