Let's divide 215431 by 74
We want to divide 215431 by 74.

Going ahead to step 1:
2 divided by 74 is 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 74

On to step 2:
74 can be fit into 21 0 times, resulting in a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Bring next digit (5) of the dividend behind the 21 and repeat the process: 215 / 74

Moving on to step 3:
74 can be fit into 215 2 times, resulting in a remainder of 67.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 148 from 215 to get 67.
Append the next digit (4) from the dividend to 67 and continue with: 674 / 74

Advancing to step 4:
When dividing 674 by 74, we get 9 with a remainder of 8.
Record the quotient 9 as the next digit in the result. 
Result so far: 29.0
Subtracting 666 from 674 leaves us with 8.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 74

Advancing to step 5:
74 goes into 83 1 times with a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 291.0
If we take 74 away from 83, we end up with 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 74

Moving on to step 6:
91 divided by 74 is 1 with a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 2911.0
If we subtract 74 from 91, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 7:
74 goes into 170 2 times with a remainder of 22.
The next digit of our result is 2. 
Result so far: 2911.2
Subtract 148 from 170 to 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.

Let's proceed to step 8:
74 goes into 220 2 times with a remainder of 72.
Write down 2 as next digit of the result. 
Result so far: 2911.22
Deduct 148 from 220 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

The quotient of the division is 2911.22, and the remainder is 0.072.
