We're dividing 378986 by 9 
Our goal is to divide 378986 by 9.

Moving on to step 1:
The number 9 fits into 3 0 times, leaving a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Bring next digit (7) of the dividend behind the 3 and repeat the process: 37 / 9

Step 2:
37 divided by 9 is 4 with a remainder of 1.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 36 from 37, we get 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 9

Step 3:
The number 9 fits into 18 2 times, leaving a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 42.0
Subtracting 18 from 18 leaves us with 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 9

Let's proceed to step 4:
9 can be fit into 9 1 times, resulting in a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 421.0
If we take 9 away from 9, we end up with 0.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 9

Let's proceed to step 5:
8 divided by 9 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 4210.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 9

Advancing to step 6:
The number 9 fits into 86 9 times, leaving a remainder of 5.
The number 9 becomes the next digit in our result. 
Result so far: 42109.0
If we take 81 away from 86, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 7:
50 divided by 9 is 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 42109.5
Deduct 45 from 50 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 8:
When dividing 50 by 9, we get 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 42109.55
If we subtract 45 from 50, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The quotient of the division is 42109.55, and the remainder is 0.005.
