We're dividing 90377807 by 9 
We want to figure out the number of times 90377807 can be divided by 9.

Going ahead to step 1:
9 goes into 9 1 times with a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 9 from 9 leaves us with 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 9

Advancing to step 2:
9 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
The remainder is 0 after subtracting 0 from 0.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 9

Advancing to step 3:
9 goes into 3 0 times with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 100.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (7) from the dividend, attach it to 3 and continue: 37 / 9

On to step 4:
The number 9 fits into 37 4 times, leaving a remainder of 1.
Write down 4 as next digit of the result. 
Result so far: 1004.0
Subtracting 36 from 37 leaves us with 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 9

Let's proceed to step 5:
The number 9 fits into 17 1 times, leaving a remainder of 8.
Use 1 as the next digit of our solution. 
Result so far: 10041.0
Subtracting 9 from 17 leaves us with 8.
Fetch the next digit (8) from the dividend, attach it to 8 and continue: 88 / 9

Step 6:
9 can be fit into 88 9 times, resulting in a remainder of 7.
Record the quotient 9 as the next digit in the result. 
Result so far: 100419.0
The remainder is 7 after subtracting 81 from 88.
Take the next digit (0) from the dividend and append it to 7, then repeat: 70 / 9

Let's proceed to step 7:
When dividing 70 by 9, we get 7 with a remainder of 7.
Use 7 as the next digit of our solution. 
Result so far: 1004197.0
If we subtract 63 from 70, we get 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 9

Advancing to step 8:
9 can be fit into 77 8 times, resulting in a remainder of 5.
Use 8 as the next digit of our solution. 
Result so far: 10041978.0
Subtract 72 from 77 to 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.

On to step 9:
50 divided by 9 is 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 10041978.5
Subtract 45 from 50 to 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.

On to step 10:
If we divide 50 by 9, we get 5 and a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 10041978.55
The remainder is 5 after subtracting 45 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Our division results in 10041978.55 with a remaining 0.005.
