Let's divide 378320 by 42
Our goal is to divide 378320 by 42.

Advancing 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
Deduct 0 from 3 and we're left with 3.
Bring next digit (7) of the dividend behind the 3 and repeat the process: 37 / 42

Step 2:
The number 42 fits into 37 0 times, leaving a remainder of 37.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 37 leaves us with 37.
Bring next digit (8) of the dividend behind the 37 and repeat the process: 378 / 42

Step 3:
42 goes into 378 9 times with a remainder of 0.
The next digit of our result is 9. 
Result so far: 9.0
If we take 378 away from 378, we end up with 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 42

Going ahead to step 4:
42 goes into 3 0 times with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 90.0
If we subtract 0 from 3, we get 3.
Append the next digit (2) from the dividend to 3 and continue with: 32 / 42

Going ahead to step 5:
42 can be fit into 32 0 times, resulting in a remainder of 32.
Put 0 as the next digit of the answer. 
Result so far: 900.0
Deduct 0 from 32 and we're left with 32.
Take the next digit (0) from the dividend and append it to 32, then repeat: 320 / 42

Going ahead to step 6:
If we divide 320 by 42, we get 7 and a remainder of 26.
Put 7 as the next digit of the answer. 
Result so far: 9007.0
If we subtract 294 from 320, we get 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 7:
42 can be fit into 260 6 times, resulting in a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 9007.6
Deduct 252 from 260 and we're left 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.

Step 8:
80 divided by 42 is 1 with a remainder of 38.
Record the quotient 1 as the next digit in the result. 
Result so far: 9007.61
If we take 42 away from 80, we end up 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.

Let's proceed to step 9:
If we divide 380 by 42, we get 9 and a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 9007.619
Subtracting 378 from 380 leaves us 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.

Let's proceed to step 10:
42 can be fit into 20 0 times, resulting in a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 9007.619
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 11:
When dividing 200 by 42, we get 4 with a remainder of 32.
Put 4 as the next digit of the answer. 
Result so far: 9007.61904
Subtracting 168 from 200 leaves us with 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 12:
If we divide 320 by 42, we get 7 and a remainder of 26.
Write down 7 as next digit of the result. 
Result so far: 9007.619047
The remainder is 26 after subtracting 294 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 13:
260 divided by 42 is 6 with a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 9007.6190476
If we take 252 away from 260, we end up 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.

On to step 14:
When dividing 80 by 42, we get 1 with a remainder of 38.
Use 1 as the next digit of our solution. 
Result so far: 9007.61904761
If we subtract 42 from 80, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

The quotient of the division is 9007.61904761, and the remainder is 3.8e-08.
