We divide 916821 by 42
We want to divide 916821 by 42.

Moving on to step 1:
42 goes into 9 0 times with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 42

Let's proceed to step 2:
91 divided by 42 is 2 with a remainder of 7.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 7 after subtracting 84 from 91.
Append the next digit (6) from the dividend to 7 and continue with: 76 / 42

Advancing to step 3:
When dividing 76 by 42, we get 1 with a remainder of 34.
Write down 1 as next digit of the result. 
Result so far: 21.0
Subtract 42 from 76 to get 34.
Take the next digit (8) from the dividend and append it to 34, then repeat: 348 / 42

Going ahead to step 4:
348 divided by 42 is 8 with a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 218.0
If we subtract 336 from 348, we get 12.
Bring next digit (2) of the dividend behind the 12 and repeat the process: 122 / 42

Advancing to step 5:
The number 42 fits into 122 2 times, leaving a remainder of 38.
Write down 2 as next digit of the result. 
Result so far: 2182.0
Subtract 84 from 122 to get 38.
Bring next digit (1) of the dividend behind the 38 and repeat the process: 381 / 42

Step 6:
When dividing 381 by 42, we get 9 with a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 21829.0
If we subtract 378 from 381, we 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.

Let's proceed to step 7:
When dividing 30 by 42, we get 0 with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 21829.0
Deduct 0 from 30 and we're left 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.

Moving on to step 8:
300 divided by 42 is 7 with a remainder of 6.
The number 7 becomes the next digit in our result. 
Result so far: 21829.07
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.

On to step 9:
If we divide 60 by 42, we get 1 and a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 21829.071
If we subtract 42 from 60, we 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:
42 can be fit into 180 4 times, resulting in a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 21829.0714
Subtracting 168 from 180 leaves us 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:
42 can be fit into 120 2 times, resulting in a remainder of 36.
The number 2 becomes the next digit in our result. 
Result so far: 21829.07142
The remainder is 36 after subtracting 84 from 120.
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:
42 goes into 360 8 times with a remainder of 24.
The number 8 becomes the next digit in our result. 
Result so far: 21829.071428
Subtracting 336 from 360 leaves us 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.

Let's proceed to step 13:
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: 21829.0714285
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.

Step 14:
42 goes into 300 7 times with a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 21829.07142857
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.

The final result is 21829.07142857 with a remainder of 6e-09.
