7422628 ÷ 90 
Let's see how many times 90 fits into 7422628.

Going ahead to step 1:
The number 90 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (4) of the dividend behind the 7 and repeat the process: 74 / 90

Going ahead to step 2:
The number 90 fits into 74 0 times, leaving a remainder of 74.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 74 and we're left with 74.
Fetch the next digit (2) from the dividend, attach it to 74 and continue: 742 / 90

Step 3:
742 divided by 90 is 8 with a remainder of 22.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we take 720 away from 742, we end up with 22.
Take the next digit (2) from the dividend and append it to 22, then repeat: 222 / 90

Going ahead to step 4:
When dividing 222 by 90, we get 2 with a remainder of 42.
Write down 2 as next digit of the result. 
Result so far: 82.0
If we subtract 180 from 222, we get 42.
Append the next digit (6) from the dividend to 42 and continue with: 426 / 90

Advancing to step 5:
When dividing 426 by 90, we get 4 with a remainder of 66.
Write down 4 as next digit of the result. 
Result so far: 824.0
Deduct 360 from 426 and we're left with 66.
Include the next digit (2) from the dividend after 66, then repeat: 662 / 90

Going ahead to step 6:
662 divided by 90 is 7 with a remainder of 32.
The next digit of our result is 7. 
Result so far: 8247.0
Subtract 630 from 662 to get 32.
Grab the next digit (8) from the dividend, add it to 32, then carry on: 328 / 90

Step 7:
90 goes into 328 3 times with a remainder of 58.
Put 3 as the next digit of the answer. 
Result so far: 82473.0
The remainder is 58 after subtracting 270 from 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 8:
90 goes into 580 6 times with a remainder of 40.
Put 6 as the next digit of the answer. 
Result so far: 82473.6
Subtract 540 from 580 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.

Going ahead to step 9:
If we divide 400 by 90, we get 4 and a remainder of 40.
The next digit of our result is 4. 
Result so far: 82473.64
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.

Let's proceed to step 10:
If we divide 400 by 90, we get 4 and a remainder of 40.
The number 4 becomes the next digit in our result. 
Result so far: 82473.644
If we take 360 away from 400, we end up 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 82473.644, with a leftover of 0.004.
