We look at the division of 756949 by 90 
We're looking to find how many times 90 goes into 756949.

On to step 1:
If we divide 7 by 90, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (5) from the dividend and append it to 7, then repeat: 75 / 90

Advancing to step 2:
90 goes into 75 0 times with a remainder of 75.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 75 after subtracting 0 from 75.
Include the next digit (6) from the dividend after 75, then repeat: 756 / 90

Advancing to step 3:
90 can be fit into 756 8 times, resulting in a remainder of 36.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtract 720 from 756 to get 36.
Append the next digit (9) from the dividend to 36 and continue with: 369 / 90

Moving on to step 4:
The number 90 fits into 369 4 times, leaving a remainder of 9.
Write down 4 as next digit of the result. 
Result so far: 84.0
If we subtract 360 from 369, we get 9.
Grab the next digit (4) from the dividend, add it to 9, then carry on: 94 / 90

Moving on to step 5:
The number 90 fits into 94 1 times, leaving a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 841.0
The remainder is 4 after subtracting 90 from 94.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 90

Going ahead to step 6:
90 can be fit into 49 0 times, resulting in a remainder of 49.
The number 0 becomes the next digit in our result. 
Result so far: 8410.0
Deduct 0 from 49 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Advancing to step 7:
If we divide 490 by 90, we get 5 and a remainder of 40.
Record the quotient 5 as the next digit in the result. 
Result so far: 8410.5
Subtract 450 from 490 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 8:
When dividing 400 by 90, we get 4 with a remainder of 40.
Put 4 as the next digit of the answer. 
Result so far: 8410.54
If we subtract 360 from 400, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 9:
The number 90 fits into 400 4 times, leaving a remainder of 40.
The next digit of our result is 4. 
Result so far: 8410.544
Deduct 360 from 400 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final outcome is 8410.544, with a leftover of 0.004.
