We divide 821691 by 42
We're looking to find how many times 42 goes into 821691.

Advancing to step 1:
8 divided by 42 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (2) of the dividend behind the 8 and repeat the process: 82 / 42

Step 2:
If we divide 82 by 42, we get 1 and a remainder of 40.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 42 from 82 leaves us with 40.
Bring next digit (1) of the dividend behind the 40 and repeat the process: 401 / 42

Step 3:
When dividing 401 by 42, we get 9 with a remainder of 23.
Write down 9 as next digit of the result. 
Result so far: 19.0
Deduct 378 from 401 and we're left with 23.
Take the next digit (6) from the dividend and append it to 23, then repeat: 236 / 42

Advancing to step 4:
42 can be fit into 236 5 times, resulting in a remainder of 26.
The number 5 becomes the next digit in our result. 
Result so far: 195.0
Deduct 210 from 236 and we're left with 26.
Take the next digit (9) from the dividend and append it to 26, then repeat: 269 / 42

Let's proceed to step 5:
The number 42 fits into 269 6 times, leaving a remainder of 17.
Put 6 as the next digit of the answer. 
Result so far: 1956.0
Subtracting 252 from 269 leaves us with 17.
Take the next digit (1) from the dividend and append it to 17, then repeat: 171 / 42

On to step 6:
42 goes into 171 4 times with a remainder of 3.
The next digit of our result is 4. 
Result so far: 19564.0
Subtract 168 from 171 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.

Advancing to step 7:
42 goes into 30 0 times with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 19564.0
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.

Advancing to step 8:
When dividing 300 by 42, we get 7 with a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 19564.07
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.

Advancing to step 9:
If we divide 60 by 42, we get 1 and a remainder of 18.
The number 1 becomes the next digit in our result. 
Result so far: 19564.071
The remainder is 18 after subtracting 42 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 10:
42 can be fit into 180 4 times, resulting in a remainder of 12.
The next digit of our result is 4. 
Result so far: 19564.0714
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:
When dividing 120 by 42, we get 2 with a remainder of 36.
Use 2 as the next digit of our solution. 
Result so far: 19564.07142
If we take 84 away from 120, we end up 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.
Record the quotient 8 as the next digit in the result. 
Result so far: 19564.071428
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.

Advancing 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: 19564.0714285
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.

Step 14:
42 goes into 300 7 times with a remainder of 6.
The number 7 becomes the next digit in our result. 
Result so far: 19564.07142857
If we take 294 away from 300, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The quotient of the division is 19564.07142857, and the remainder is 6e-09.
