90786120 ÷ 480 
Our goal is to divide 90786120 by 480.

Let's proceed to step 1:
9 divided by 480 is 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 480

Step 2:
480 goes into 90 0 times with a remainder of 90.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 90, we end up with 90.
Bring next digit (7) of the dividend behind the 90 and repeat the process: 907 / 480

Moving on to step 3:
When dividing 907 by 480, we get 1 with a remainder of 427.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 480 from 907 to get 427.
Append the next digit (8) from the dividend to 427 and continue with: 4278 / 480

Going ahead to step 4:
When dividing 4278 by 480, we get 8 with a remainder of 438.
Put 8 as the next digit of the answer. 
Result so far: 18.0
Deduct 3840 from 4278 and we're left with 438.
Bring next digit (6) of the dividend behind the 438 and repeat the process: 4386 / 480

Step 5:
The number 480 fits into 4386 9 times, leaving a remainder of 66.
Record the quotient 9 as the next digit in the result. 
Result so far: 189.0
Deduct 4320 from 4386 and we're left with 66.
Grab the next digit (1) from the dividend, add it to 66, then carry on: 661 / 480

Advancing to step 6:
When dividing 661 by 480, we get 1 with a remainder of 181.
Record the quotient 1 as the next digit in the result. 
Result so far: 1891.0
If we subtract 480 from 661, we get 181.
Grab the next digit (2) from the dividend, add it to 181, then carry on: 1812 / 480

Step 7:
480 goes into 1812 3 times with a remainder of 372.
The next digit of our result is 3. 
Result so far: 18913.0
If we subtract 1440 from 1812, we get 372.
Fetch the next digit (0) from the dividend, attach it to 372 and continue: 3720 / 480

Moving on to step 8:
480 can be fit into 3720 7 times, resulting in a remainder of 360.
Use 7 as the next digit of our solution. 
Result so far: 189137.0
If we subtract 3360 from 3720, we get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Step 9:
If we divide 3600 by 480, we get 7 and a remainder of 240.
The number 7 becomes the next digit in our result. 
Result so far: 189137.7
Subtract 3360 from 3600 to get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Moving on to step 10:
When dividing 2400 by 480, we get 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 189137.75
Subtracting 2400 from 2400 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 11:
0 divided by 480 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 189137.75
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 12:
When dividing 0 by 480, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 189137.75
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 189137.75 with a remaining 0.0.
