Let's divide 40557454 by 42
We want to figure out the number of times 40557454 can be divided by 42.

Moving on to step 1:
When dividing 4 by 42, we get 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 42

Moving on to step 2:
When dividing 40 by 42, we get 0 with a remainder of 40.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 40 and we're left with 40.
Include the next digit (5) from the dividend after 40, then repeat: 405 / 42

Advancing to step 3:
If we divide 405 by 42, we get 9 and a remainder of 27.
The next digit of our result is 9. 
Result so far: 9.0
If we take 378 away from 405, we end up with 27.
Include the next digit (5) from the dividend after 27, then repeat: 275 / 42

Step 4:
42 can be fit into 275 6 times, resulting in a remainder of 23.
The next digit of our result is 6. 
Result so far: 96.0
If we subtract 252 from 275, we get 23.
Grab the next digit (7) from the dividend, add it to 23, then carry on: 237 / 42

Moving on to step 5:
When dividing 237 by 42, we get 5 with a remainder of 27.
Record the quotient 5 as the next digit in the result. 
Result so far: 965.0
The remainder is 27 after subtracting 210 from 237.
Append the next digit (4) from the dividend to 27 and continue with: 274 / 42

Advancing to step 6:
42 can be fit into 274 6 times, resulting in a remainder of 22.
Write down 6 as next digit of the result. 
Result so far: 9656.0
If we take 252 away from 274, we end up with 22.
Append the next digit (5) from the dividend to 22 and continue with: 225 / 42

Let's proceed to step 7:
When dividing 225 by 42, we get 5 with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 96565.0
If we take 210 away from 225, we end up with 15.
Fetch the next digit (4) from the dividend, attach it to 15 and continue: 154 / 42

Advancing to step 8:
The number 42 fits into 154 3 times, leaving a remainder of 28.
Write down 3 as next digit of the result. 
Result so far: 965653.0
Subtracting 126 from 154 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 9:
If we divide 280 by 42, we get 6 and a remainder of 28.
The next digit of our result is 6. 
Result so far: 965653.6
Subtract 252 from 280 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 10:
280 divided by 42 is 6 with a remainder of 28.
Use 6 as the next digit of our solution. 
Result so far: 965653.66
If we take 252 away from 280, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

After the division, we end up with 965653.66 and a remainder of 0.028.
