321646 ÷ 42 
Let's see how many times 42 fits into 321646.

Moving on to step 1:
If we divide 3 by 42, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Include the next digit (2) from the dividend after 3, then repeat: 32 / 42

On to step 2:
42 goes into 32 0 times with a remainder of 32.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 32 and we're left with 32.
Take the next digit (1) from the dividend and append it to 32, then repeat: 321 / 42

Step 3:
When dividing 321 by 42, we get 7 with a remainder of 27.
Write down 7 as next digit of the result. 
Result so far: 7.0
The remainder is 27 after subtracting 294 from 321.
Bring next digit (6) of the dividend behind the 27 and repeat the process: 276 / 42

On to step 4:
42 can be fit into 276 6 times, resulting in a remainder of 24.
Record the quotient 6 as the next digit in the result. 
Result so far: 76.0
Subtracting 252 from 276 leaves us with 24.
Fetch the next digit (4) from the dividend, attach it to 24 and continue: 244 / 42

Moving on to step 5:
When dividing 244 by 42, we get 5 with a remainder of 34.
The next digit of our result is 5. 
Result so far: 765.0
The remainder is 34 after subtracting 210 from 244.
Take the next digit (6) from the dividend and append it to 34, then repeat: 346 / 42

Advancing to step 6:
The number 42 fits into 346 8 times, leaving a remainder of 10.
Use 8 as the next digit of our solution. 
Result so far: 7658.0
Subtract 336 from 346 to get 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 7:
42 goes into 100 2 times with a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 7658.2
Subtract 84 from 100 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 8:
When dividing 160 by 42, we get 3 with a remainder of 34.
The number 3 becomes the next digit in our result. 
Result so far: 7658.23
If we take 126 away from 160, we end up 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.

Step 9:
42 goes into 340 8 times with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 7658.238
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.

Going ahead to step 10:
42 can be fit into 40 0 times, resulting in a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 7658.238
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 11:
42 can be fit into 400 9 times, resulting in a remainder of 22.
The next digit of our result is 9. 
Result so far: 7658.23809
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.

On to step 12:
The number 42 fits into 220 5 times, leaving a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 7658.238095
If we subtract 210 from 220, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 13:
100 divided by 42 is 2 with a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 7658.2380952
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.

Step 14:
42 goes into 160 3 times with a remainder of 34.
Record the quotient 3 as the next digit in the result. 
Result so far: 7658.23809523
Subtracting 126 from 160 leaves us 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.

Our division results in 7658.23809523 with a remaining 3.4e-08.
