We look at the division of 561454 by 42 
Let's see how many times 42 fits into 561454.

Step 1:
If we divide 5 by 42, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Fetch the next digit (6) from the dividend, attach it to 5 and continue: 56 / 42

Let's proceed to step 2:
When dividing 56 by 42, we get 1 with a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 42 from 56 to get 14.
Append the next digit (1) from the dividend to 14 and continue with: 141 / 42

Moving on to step 3:
When dividing 141 by 42, we get 3 with a remainder of 15.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Subtracting 126 from 141 leaves us with 15.
Fetch the next digit (4) from the dividend, attach it to 15 and continue: 154 / 42

On to step 4:
42 can be fit into 154 3 times, resulting in a remainder of 28.
The next digit of our result is 3. 
Result so far: 133.0
Subtract 126 from 154 to get 28.
Grab the next digit (5) from the dividend, add it to 28, then carry on: 285 / 42

Advancing to step 5:
If we divide 285 by 42, we get 6 and a remainder of 33.
The number 6 becomes the next digit in our result. 
Result so far: 1336.0
Subtract 252 from 285 to get 33.
Fetch the next digit (4) from the dividend, attach it to 33 and continue: 334 / 42

Step 6:
If we divide 334 by 42, we get 7 and a remainder of 40.
The next digit of our result is 7. 
Result so far: 13367.0
If we subtract 294 from 334, we 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.

On to step 7:
42 can be fit into 400 9 times, resulting in a remainder of 22.
The number 9 becomes the next digit in our result. 
Result so far: 13367.9
Deduct 378 from 400 and we're left 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.

Going ahead to step 8:
The number 42 fits into 220 5 times, leaving a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 13367.95
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 9:
If we divide 100 by 42, we get 2 and a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 13367.952
If we subtract 84 from 100, we 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.

Step 10:
The number 42 fits into 160 3 times, leaving a remainder of 34.
Use 3 as the next digit of our solution. 
Result so far: 13367.9523
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 11:
42 goes into 340 8 times with a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 13367.95238
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 12:
40 divided by 42 is 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 13367.95238
Subtracting 0 from 40 leaves us 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.

On to step 13:
400 divided by 42 is 9 with a remainder of 22.
Write down 9 as next digit of the result. 
Result so far: 13367.9523809
If we take 378 away from 400, we end up 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 14:
220 divided by 42 is 5 with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 13367.95238095
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.

The final result is 13367.95238095 with a remainder of 1e-08.
