We divide 740621 by 90
Our goal is to divide 740621 by 90.

Moving on to step 1:
7 divided by 90 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Fetch the next digit (4) from the dividend, attach it to 7 and continue: 74 / 90

Going ahead to step 2:
90 can be fit into 74 0 times, resulting in a remainder of 74.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 74, we end up with 74.
Grab the next digit (0) from the dividend, add it to 74, then carry on: 740 / 90

Let's proceed to step 3:
90 goes into 740 8 times with a remainder of 20.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtract 720 from 740 to get 20.
Append the next digit (6) from the dividend to 20 and continue with: 206 / 90

Going ahead to step 4:
90 can be fit into 206 2 times, resulting in a remainder of 26.
The number 2 becomes the next digit in our result. 
Result so far: 82.0
If we take 180 away from 206, we end up with 26.
Include the next digit (2) from the dividend after 26, then repeat: 262 / 90

Let's proceed to step 5:
262 divided by 90 is 2 with a remainder of 82.
The next digit of our result is 2. 
Result so far: 822.0
The remainder is 82 after subtracting 180 from 262.
Bring next digit (1) of the dividend behind the 82 and repeat the process: 821 / 90

Moving on to step 6:
821 divided by 90 is 9 with a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 8229.0
Subtract 810 from 821 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 7:
If we divide 110 by 90, we get 1 and a remainder of 20.
Use 1 as the next digit of our solution. 
Result so far: 8229.1
Subtract 90 from 110 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 8:
When dividing 200 by 90, we get 2 with a remainder of 20.
Use 2 as the next digit of our solution. 
Result so far: 8229.12
If we subtract 180 from 200, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 9:
90 can be fit into 200 2 times, resulting in a remainder of 20.
Put 2 as the next digit of the answer. 
Result so far: 8229.122
If we take 180 away from 200, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final result is 8229.122 with a remainder of 0.002.
