We're dividing 757080 by 90 
We want to figure out the number of times 757080 can be divided by 90.

Moving on to step 1:
90 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (5) from the dividend, add it to 7, then carry on: 75 / 90

Step 2:
75 divided by 90 is 0 with a remainder of 75.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 75 to get 75.
Take the next digit (7) from the dividend and append it to 75, then repeat: 757 / 90

Step 3:
90 can be fit into 757 8 times, resulting in a remainder of 37.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtract 720 from 757 to get 37.
Append the next digit (0) from the dividend to 37 and continue with: 370 / 90

Let's proceed to step 4:
370 divided by 90 is 4 with a remainder of 10.
Put 4 as the next digit of the answer. 
Result so far: 84.0
Subtracting 360 from 370 leaves us with 10.
Fetch the next digit (8) from the dividend, attach it to 10 and continue: 108 / 90

Step 5:
90 goes into 108 1 times with a remainder of 18.
The next digit of our result is 1. 
Result so far: 841.0
Deduct 90 from 108 and we're left with 18.
Fetch the next digit (0) from the dividend, attach it to 18 and continue: 180 / 90

On to step 6:
When dividing 180 by 90, we get 2 with a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 8412.0
If we subtract 180 from 180, we 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.

Moving on to step 7:
When dividing 0 by 90, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 8412.0
If we subtract 0 from 0, we 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.

Let's proceed to step 8:
90 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 8412.0
If we subtract 0 from 0, we 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.

The final outcome is 8412.0, with a leftover of 0.0.
