Let's divide 396673 by 42
We want to figure out the number of times 396673 can be divided by 42.

Advancing to step 1:
If we divide 3 by 42, we get 0 and a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 42

On to step 2:
If we divide 39 by 42, we get 0 and a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 39, we get 39.
Bring next digit (6) of the dividend behind the 39 and repeat the process: 396 / 42

Going ahead to step 3:
42 goes into 396 9 times with a remainder of 18.
The next digit of our result is 9. 
Result so far: 9.0
Deduct 378 from 396 and we're left with 18.
Grab the next digit (6) from the dividend, add it to 18, then carry on: 186 / 42

On to step 4:
186 divided by 42 is 4 with a remainder of 18.
Write down 4 as next digit of the result. 
Result so far: 94.0
The remainder is 18 after subtracting 168 from 186.
Include the next digit (7) from the dividend after 18, then repeat: 187 / 42

Moving on to step 5:
187 divided by 42 is 4 with a remainder of 19.
The number 4 becomes the next digit in our result. 
Result so far: 944.0
If we take 168 away from 187, we end up with 19.
Bring next digit (3) of the dividend behind the 19 and repeat the process: 193 / 42

Going ahead to step 6:
42 goes into 193 4 times with a remainder of 25.
Use 4 as the next digit of our solution. 
Result so far: 9444.0
Deduct 168 from 193 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 7:
The number 42 fits into 250 5 times, leaving a remainder of 40.
The next digit of our result is 5. 
Result so far: 9444.5
If we take 210 away from 250, we end up 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.

Going ahead to step 8:
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: 9444.59
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.

On to step 9:
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: 9444.595
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.

Step 10:
100 divided by 42 is 2 with a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 9444.5952
Deduct 84 from 100 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 11:
The number 42 fits into 160 3 times, leaving a remainder of 34.
The number 3 becomes the next digit in our result. 
Result so far: 9444.59523
If we take 126 away from 160, we end up with 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 12:
When dividing 340 by 42, we get 8 with a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 9444.595238
Subtracting 336 from 340 leaves us 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.

Let's proceed to step 13:
42 goes into 40 0 times with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 9444.595238
Subtract 0 from 40 to 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.

Moving on to step 14:
The number 42 fits into 400 9 times, leaving a remainder of 22.
Put 9 as the next digit of the answer. 
Result so far: 9444.59523809
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.

Our division results in 9444.59523809 with a remaining 2.2e-08.
