Let's divide 174491 by 42
We want to figure out the number of times 174491 can be divided by 42.

Going ahead to step 1:
The number 42 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 42

Let's proceed to step 2:
42 goes into 17 0 times with a remainder of 17.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 17, we get 17.
Append the next digit (4) from the dividend to 17 and continue with: 174 / 42

On to step 3:
When dividing 174 by 42, we get 4 with a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we subtract 168 from 174, we get 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 42

Let's proceed to step 4:
When dividing 64 by 42, we get 1 with a remainder of 22.
The number 1 becomes the next digit in our result. 
Result so far: 41.0
If we take 42 away from 64, we end up with 22.
Bring next digit (9) of the dividend behind the 22 and repeat the process: 229 / 42

On to step 5:
If we divide 229 by 42, we get 5 and a remainder of 19.
Use 5 as the next digit of our solution. 
Result so far: 415.0
If we take 210 away from 229, we end up with 19.
Fetch the next digit (1) from the dividend, attach it to 19 and continue: 191 / 42

On to step 6:
42 can be fit into 191 4 times, resulting in a remainder of 23.
The next digit of our result is 4. 
Result so far: 4154.0
The remainder is 23 after subtracting 168 from 191.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 7:
230 divided by 42 is 5 with a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 4154.5
Subtract 210 from 230 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 8:
When dividing 200 by 42, we get 4 with a remainder of 32.
Write down 4 as next digit of the result. 
Result so far: 4154.54
If we take 168 away from 200, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 9:
When dividing 320 by 42, we get 7 with a remainder of 26.
The next digit of our result is 7. 
Result so far: 4154.547
If we take 294 away from 320, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 10:
42 can be fit into 260 6 times, resulting in a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 4154.5476
The remainder is 8 after subtracting 252 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 11:
42 can be fit into 80 1 times, resulting in a remainder of 38.
The next digit of our result is 1. 
Result so far: 4154.54761
Subtracting 42 from 80 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 12:
The number 42 fits into 380 9 times, leaving a remainder of 2.
The next digit of our result is 9. 
Result so far: 4154.547619
The remainder is 2 after subtracting 378 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 13:
20 divided by 42 is 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 4154.547619
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 14:
If we divide 200 by 42, we get 4 and a remainder of 32.
Put 4 as the next digit of the answer. 
Result so far: 4154.54761904
Subtract 168 from 200 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final result is 4154.54761904 with a remainder of 3.2e-08.
