We're dividing 9146 by 42 
We're looking to find how many times 42 goes into 9146.

Going ahead to step 1:
The number 42 fits into 9 0 times, leaving a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 42

Going ahead to step 2:
42 goes into 91 2 times with a remainder of 7.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 84 from 91 leaves us with 7.
Bring next digit (4) of the dividend behind the 7 and repeat the process: 74 / 42

Advancing to step 3:
74 divided by 42 is 1 with a remainder of 32.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
Subtract 42 from 74 to get 32.
Append the next digit (6) from the dividend to 32 and continue with: 326 / 42

Moving on to step 4:
The number 42 fits into 326 7 times, leaving a remainder of 32.
Put 7 as the next digit of the answer. 
Result so far: 217.0
If we subtract 294 from 326, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 5:
When dividing 320 by 42, we get 7 with a remainder of 26.
The number 7 becomes the next digit in our result. 
Result so far: 217.7
Subtracting 294 from 320 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 6:
If we divide 260 by 42, we get 6 and a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 217.76
Subtracting 252 from 260 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 7:
42 goes into 80 1 times with a remainder of 38.
Write down 1 as next digit of the result. 
Result so far: 217.761
Subtracting 42 from 80 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 8:
When dividing 380 by 42, we get 9 with a remainder of 2.
Put 9 as the next digit of the answer. 
Result so far: 217.7619
Deduct 378 from 380 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 9:
42 goes into 20 0 times with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 217.7619
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 10:
42 can be fit into 200 4 times, resulting in a remainder of 32.
Record the quotient 4 as the next digit in the result. 
Result so far: 217.761904
The remainder is 32 after subtracting 168 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 11:
320 divided by 42 is 7 with a remainder of 26.
Put 7 as the next digit of the answer. 
Result so far: 217.7619047
If we take 294 away from 320, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 12:
260 divided by 42 is 6 with a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 217.76190476
Subtracting 252 from 260 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final outcome is 217.76190476, with a leftover of 8e-09.
