Let's divide 174403 by 42
We're looking to find how many times 42 goes into 174403.

Going ahead to step 1:
42 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 42

Let's proceed to step 2:
When dividing 17 by 42, we get 0 with a remainder of 17.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 17 and we're left with 17.
Take the next digit (4) from the dividend and append it to 17, then repeat: 174 / 42

Advancing to step 3:
42 can be fit into 174 4 times, resulting in a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtract 168 from 174 to get 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 42

On to step 4:
64 divided by 42 is 1 with a remainder of 22.
Record the quotient 1 as the next digit in the result. 
Result so far: 41.0
If we subtract 42 from 64, we get 22.
Grab the next digit (0) from the dividend, add it to 22, then carry on: 220 / 42

Let's proceed to step 5:
42 goes into 220 5 times with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 415.0
If we subtract 210 from 220, we get 10.
Grab the next digit (3) from the dividend, add it to 10, then carry on: 103 / 42

Moving on to step 6:
When dividing 103 by 42, we get 2 with a remainder of 19.
The number 2 becomes the next digit in our result. 
Result so far: 4152.0
Deduct 84 from 103 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 7:
190 divided by 42 is 4 with a remainder of 22.
Use 4 as the next digit of our solution. 
Result so far: 4152.4
If we take 168 away from 190, 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.

Moving on to step 8:
42 can be fit into 220 5 times, resulting in a remainder of 10.
The next digit of our result is 5. 
Result so far: 4152.45
Subtract 210 from 220 to 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.

Let's proceed to step 9:
When dividing 100 by 42, we get 2 with a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 4152.452
The remainder is 16 after subtracting 84 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 10:
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: 4152.4523
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.

On to step 11:
42 can be fit into 340 8 times, resulting in a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 4152.45238
Deduct 336 from 340 and we're left 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.

Moving on to step 12:
If we divide 40 by 42, we get 0 and a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 4152.45238
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:
42 goes into 400 9 times with a remainder of 22.
Record the quotient 9 as the next digit in the result. 
Result so far: 4152.4523809
The remainder is 22 after subtracting 378 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 14:
The number 42 fits into 220 5 times, leaving a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 4152.45238095
If we take 210 away from 220, we end up 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.

After the division, we end up with 4152.45238095 and a remainder of 1e-08.
