We divide 821439 by 42
Our goal is to divide 821439 by 42.

Step 1:
42 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (2) from the dividend after 8, then repeat: 82 / 42

On to step 2:
42 can be fit into 82 1 times, resulting in a remainder of 40.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 42 from 82, we get 40.
Bring next digit (1) of the dividend behind the 40 and repeat the process: 401 / 42

Let's proceed to step 3:
42 can be fit into 401 9 times, resulting in a remainder of 23.
Put 9 as the next digit of the answer. 
Result so far: 19.0
If we take 378 away from 401, we end up with 23.
Append the next digit (4) from the dividend to 23 and continue with: 234 / 42

Advancing to step 4:
234 divided by 42 is 5 with a remainder of 24.
The next digit of our result is 5. 
Result so far: 195.0
If we subtract 210 from 234, we get 24.
Include the next digit (3) from the dividend after 24, then repeat: 243 / 42

Advancing to step 5:
243 divided by 42 is 5 with a remainder of 33.
Use 5 as the next digit of our solution. 
Result so far: 1955.0
Deduct 210 from 243 and we're left with 33.
Grab the next digit (9) from the dividend, add it to 33, then carry on: 339 / 42

Let's proceed to step 6:
42 can be fit into 339 8 times, resulting in a remainder of 3.
The next digit of our result is 8. 
Result so far: 19558.0
Subtract 336 from 339 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 7:
30 divided by 42 is 0 with a remainder of 30.
The next digit of our result is 0. 
Result so far: 19558.0
If we take 0 away from 30, 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 8:
42 can be fit into 300 7 times, resulting in a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 19558.07
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.

Let's proceed to step 9:
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: 19558.071
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 10:
If we divide 180 by 42, we get 4 and a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 19558.0714
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.

Advancing to step 11:
The number 42 fits into 120 2 times, leaving a remainder of 36.
Put 2 as the next digit of the answer. 
Result so far: 19558.07142
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.

Advancing to step 12:
360 divided by 42 is 8 with a remainder of 24.
Put 8 as the next digit of the answer. 
Result so far: 19558.071428
If we subtract 336 from 360, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 13:
If we divide 240 by 42, we get 5 and a remainder of 30.
The next digit of our result is 5. 
Result so far: 19558.0714285
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 14:
300 divided by 42 is 7 with a remainder of 6.
Use 7 as the next digit of our solution. 
Result so far: 19558.07142857
If we subtract 294 from 300, we 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.

Our division results in 19558.07142857 with a remaining 6e-09.
