334899 ÷ 42 
We want to figure out the number of times 334899 can be divided by 42.

On to step 1:
42 can be fit into 3 0 times, resulting in a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (3) from the dividend, add it to 3, then carry on: 33 / 42

Moving on to step 2:
The number 42 fits into 33 0 times, leaving a remainder of 33.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 33 to get 33.
Include the next digit (4) from the dividend after 33, then repeat: 334 / 42

On to step 3:
42 goes into 334 7 times with a remainder of 40.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Deduct 294 from 334 and we're left with 40.
Bring next digit (8) of the dividend behind the 40 and repeat the process: 408 / 42

On to step 4:
42 goes into 408 9 times with a remainder of 30.
Put 9 as the next digit of the answer. 
Result so far: 79.0
If we take 378 away from 408, we end up with 30.
Append the next digit (9) from the dividend to 30 and continue with: 309 / 42

Step 5:
When dividing 309 by 42, we get 7 with a remainder of 15.
Put 7 as the next digit of the answer. 
Result so far: 797.0
Subtracting 294 from 309 leaves us with 15.
Bring next digit (9) of the dividend behind the 15 and repeat the process: 159 / 42

On to step 6:
159 divided by 42 is 3 with a remainder of 33.
Write down 3 as next digit of the result. 
Result so far: 7973.0
Subtracting 126 from 159 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Advancing to step 7:
The number 42 fits into 330 7 times, leaving a remainder of 36.
Put 7 as the next digit of the answer. 
Result so far: 7973.7
Subtract 294 from 330 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 8:
42 can be fit into 360 8 times, resulting in a remainder of 24.
The next digit of our result is 8. 
Result so far: 7973.78
If we subtract 336 from 360, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 9:
42 can be fit into 240 5 times, resulting in a remainder of 30.
The next digit of our result is 5. 
Result so far: 7973.785
Deduct 210 from 240 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 10:
42 goes into 300 7 times with a remainder of 6.
The next digit of our result is 7. 
Result so far: 7973.7857
If we take 294 away from 300, we end up 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.

Advancing to step 11:
The number 42 fits into 60 1 times, leaving a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 7973.78571
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.

Moving on to step 12:
42 goes into 180 4 times with a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 7973.785714
Deduct 168 from 180 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 13:
120 divided by 42 is 2 with a remainder of 36.
The next digit of our result is 2. 
Result so far: 7973.7857142
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 14:
When dividing 360 by 42, we get 8 with a remainder of 24.
Write down 8 as next digit of the result. 
Result so far: 7973.78571428
Deduct 336 from 360 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final outcome is 7973.78571428, with a leftover of 2.4e-08.
