344157 ÷ 42 
Our goal is to divide 344157 by 42.

On to step 1:
If we divide 3 by 42, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (4) from the dividend and append it to 3, then repeat: 34 / 42

Let's proceed to step 2:
If we divide 34 by 42, we get 0 and a remainder of 34.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 34 leaves us with 34.
Take the next digit (4) from the dividend and append it to 34, then repeat: 344 / 42

Let's proceed to step 3:
If we divide 344 by 42, we get 8 and a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtracting 336 from 344 leaves us with 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 42

Advancing to step 4:
42 goes into 81 1 times with a remainder of 39.
The next digit of our result is 1. 
Result so far: 81.0
The remainder is 39 after subtracting 42 from 81.
Append the next digit (5) from the dividend to 39 and continue with: 395 / 42

Let's proceed to step 5:
If we divide 395 by 42, we get 9 and a remainder of 17.
Use 9 as the next digit of our solution. 
Result so far: 819.0
Subtract 378 from 395 to get 17.
Bring next digit (7) of the dividend behind the 17 and repeat the process: 177 / 42

Going ahead to step 6:
177 divided by 42 is 4 with a remainder of 9.
Put 4 as the next digit of the answer. 
Result so far: 8194.0
Subtracting 168 from 177 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 7:
42 can be fit into 90 2 times, resulting in a remainder of 6.
The next digit of our result is 2. 
Result so far: 8194.2
Subtracting 84 from 90 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 8:
42 goes into 60 1 times with a remainder of 18.
Write down 1 as next digit of the result. 
Result so far: 8194.21
Deduct 42 from 60 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 9:
42 can be fit into 180 4 times, resulting in a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 8194.214
If we subtract 168 from 180, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 10:
120 divided by 42 is 2 with a remainder of 36.
The next digit of our result is 2. 
Result so far: 8194.2142
Subtract 84 from 120 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 11:
360 divided by 42 is 8 with a remainder of 24.
Record the quotient 8 as the next digit in the result. 
Result so far: 8194.21428
The remainder is 24 after subtracting 336 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 12:
42 goes into 240 5 times with a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 8194.214285
Subtract 210 from 240 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 13:
When dividing 300 by 42, we get 7 with a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 8194.2142857
Subtract 294 from 300 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 14:
60 divided by 42 is 1 with a remainder of 18.
The number 1 becomes the next digit in our result. 
Result so far: 8194.21428571
If we take 42 away from 60, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

After the division, we end up with 8194.21428571 and a remainder of 1.8e-08.
