749161 ÷ 90 
Let's see how many times 90 fits into 749161.

Let's proceed to step 1:
The number 90 fits into 7 0 times, leaving a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (4) of the dividend behind the 7 and repeat the process: 74 / 90

On to step 2:
90 goes into 74 0 times with a remainder of 74.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 74 leaves us with 74.
Bring next digit (9) of the dividend behind the 74 and repeat the process: 749 / 90

Moving on to step 3:
If we divide 749 by 90, we get 8 and a remainder of 29.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we subtract 720 from 749, we get 29.
Bring next digit (1) of the dividend behind the 29 and repeat the process: 291 / 90

Let's proceed to step 4:
When dividing 291 by 90, we get 3 with a remainder of 21.
The next digit of our result is 3. 
Result so far: 83.0
If we take 270 away from 291, we end up with 21.
Include the next digit (6) from the dividend after 21, then repeat: 216 / 90

Let's proceed to step 5:
When dividing 216 by 90, we get 2 with a remainder of 36.
Put 2 as the next digit of the answer. 
Result so far: 832.0
If we subtract 180 from 216, we get 36.
Bring next digit (1) of the dividend behind the 36 and repeat the process: 361 / 90

Step 6:
90 can be fit into 361 4 times, resulting in a remainder of 1.
Record the quotient 4 as the next digit in the result. 
Result so far: 8324.0
Subtracting 360 from 361 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 7:
90 can be fit into 10 0 times, resulting in a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 8324.0
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
100 divided by 90 is 1 with a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 8324.01
Deduct 90 from 100 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 9:
100 divided by 90 is 1 with a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 8324.011
Deduct 90 from 100 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

In conclusion, the division gives 8324.011 with a balance of 0.001.
