392199 divided by 42 
We want to figure out the number of times 392199 can be divided by 42.

Going ahead to step 1:
42 can be fit into 3 0 times, resulting in a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 42

Let's proceed to step 2:
42 goes into 39 0 times with a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 39 and we're left with 39.
Grab the next digit (2) from the dividend, add it to 39, then carry on: 392 / 42

Moving on to step 3:
When dividing 392 by 42, we get 9 with a remainder of 14.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we take 378 away from 392, we end up with 14.
Take the next digit (1) from the dividend and append it to 14, then repeat: 141 / 42

Step 4:
If we divide 141 by 42, we get 3 and a remainder of 15.
Use 3 as the next digit of our solution. 
Result so far: 93.0
If we take 126 away from 141, we end up with 15.
Grab the next digit (9) from the dividend, add it to 15, then carry on: 159 / 42

Moving on to step 5:
42 can be fit into 159 3 times, resulting in a remainder of 33.
The next digit of our result is 3. 
Result so far: 933.0
Subtracting 126 from 159 leaves us with 33.
Include the next digit (9) from the dividend after 33, then repeat: 339 / 42

Advancing to step 6:
When dividing 339 by 42, we get 8 with a remainder of 3.
Put 8 as the next digit of the answer. 
Result so far: 9338.0
Subtracting 336 from 339 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 7:
30 divided by 42 is 0 with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 9338.0
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 8:
300 divided by 42 is 7 with a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 9338.07
The remainder is 6 after subtracting 294 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 9:
The number 42 fits into 60 1 times, leaving a remainder of 18.
Use 1 as the next digit of our solution. 
Result so far: 9338.071
Subtracting 42 from 60 leaves us 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 10:
42 goes into 180 4 times with a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 9338.0714
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.

Going ahead to step 11:
120 divided by 42 is 2 with a remainder of 36.
The next digit of our result is 2. 
Result so far: 9338.07142
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 12:
The number 42 fits into 360 8 times, leaving a remainder of 24.
Record the quotient 8 as the next digit in the result. 
Result so far: 9338.071428
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.

Step 13:
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: 9338.0714285
Subtracting 210 from 240 leaves us 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 14:
The number 42 fits into 300 7 times, leaving a remainder of 6.
Use 7 as the next digit of our solution. 
Result so far: 9338.07142857
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.

The final outcome is 9338.07142857, with a leftover of 6e-09.
