We look at the division of 321880 by 42 
We're looking to find how many times 42 goes into 321880.

On to step 1:
42 goes into 3 0 times with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Take the next digit (2) from the dividend and append it to 3, then repeat: 32 / 42

Let's proceed 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
If we subtract 0 from 32, we get 32.
Fetch the next digit (1) from the dividend, attach it to 32 and continue: 321 / 42

Moving on to step 3:
321 divided by 42 is 7 with a remainder of 27.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we take 294 away from 321, we end up with 27.
Bring next digit (8) of the dividend behind the 27 and repeat the process: 278 / 42

Let's proceed to step 4:
42 goes into 278 6 times with a remainder of 26.
Use 6 as the next digit of our solution. 
Result so far: 76.0
Subtracting 252 from 278 leaves us with 26.
Fetch the next digit (8) from the dividend, attach it to 26 and continue: 268 / 42

Let's proceed to step 5:
If we divide 268 by 42, we get 6 and a remainder of 16.
Record the quotient 6 as the next digit in the result. 
Result so far: 766.0
If we take 252 away from 268, we end up with 16.
Append the next digit (0) from the dividend to 16 and continue with: 160 / 42

Going ahead to step 6:
When dividing 160 by 42, we get 3 with a remainder of 34.
Put 3 as the next digit of the answer. 
Result so far: 7663.0
Subtract 126 from 160 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 7:
When dividing 340 by 42, we get 8 with a remainder of 4.
The next digit of our result is 8. 
Result so far: 7663.8
Subtract 336 from 340 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 8:
42 goes into 40 0 times with a remainder of 40.
The next digit of our result is 0. 
Result so far: 7663.8
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 9:
When dividing 400 by 42, we get 9 with a remainder of 22.
Put 9 as the next digit of the answer. 
Result so far: 7663.809
Subtracting 378 from 400 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 10:
220 divided by 42 is 5 with a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 7663.8095
Subtracting 210 from 220 leaves us with 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 11:
The number 42 fits into 100 2 times, leaving a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 7663.80952
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.

Advancing to step 12:
When dividing 160 by 42, we get 3 with a remainder of 34.
Put 3 as the next digit of the answer. 
Result so far: 7663.809523
The remainder is 34 after subtracting 126 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 13:
If we divide 340 by 42, we get 8 and a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 7663.8095238
If we take 336 away from 340, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 14:
42 goes into 40 0 times with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 7663.8095238
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Our division results in 7663.8095238 with a remaining 4e-08.
