We're dividing 354147 by 42 
We want to figure out the number of times 354147 can be divided by 42.

Step 1:
3 divided by 42 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (5) from the dividend, add it to 3, then carry on: 35 / 42

Moving on to step 2:
42 can be fit into 35 0 times, resulting in a remainder of 35.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 35 and we're left with 35.
Take the next digit (4) from the dividend and append it to 35, then repeat: 354 / 42

On to step 3:
When dividing 354 by 42, we get 8 with a remainder of 18.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we subtract 336 from 354, we get 18.
Bring next digit (1) of the dividend behind the 18 and repeat the process: 181 / 42

Going ahead to step 4:
When dividing 181 by 42, we get 4 with a remainder of 13.
Use 4 as the next digit of our solution. 
Result so far: 84.0
The remainder is 13 after subtracting 168 from 181.
Fetch the next digit (4) from the dividend, attach it to 13 and continue: 134 / 42

On to step 5:
134 divided by 42 is 3 with a remainder of 8.
Put 3 as the next digit of the answer. 
Result so far: 843.0
The remainder is 8 after subtracting 126 from 134.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 42

Step 6:
42 can be fit into 87 2 times, resulting in a remainder of 3.
Write down 2 as next digit of the result. 
Result so far: 8432.0
Deduct 84 from 87 and we're left 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.

Let's proceed to step 7:
42 can be fit into 30 0 times, resulting in a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 8432.0
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.

On to step 8:
42 can be fit into 300 7 times, resulting in a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 8432.07
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.

Going ahead to step 9:
60 divided by 42 is 1 with a remainder of 18.
Write down 1 as next digit of the result. 
Result so far: 8432.071
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 can be fit into 180 4 times, resulting in a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 8432.0714
Subtract 168 from 180 to 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 11:
120 divided by 42 is 2 with a remainder of 36.
Write down 2 as next digit of the result. 
Result so far: 8432.07142
Deduct 84 from 120 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 12:
360 divided by 42 is 8 with a remainder of 24.
The next digit of our result is 8. 
Result so far: 8432.071428
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.

Moving on to step 13:
42 can be fit into 240 5 times, resulting in a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 8432.0714285
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.

Step 14:
The number 42 fits into 300 7 times, leaving a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 8432.07142857
If we subtract 294 from 300, we 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 result is 8432.07142857 with a remainder of 6e-09.
