Let's divide 422350 by 90
Let's see how many times 90 fits into 422350.

On to step 1:
90 goes into 4 0 times with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 90

Moving on to step 2:
When dividing 42 by 90, we get 0 with a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 42 after subtracting 0 from 42.
Grab the next digit (2) from the dividend, add it to 42, then carry on: 422 / 90

Moving on to step 3:
The number 90 fits into 422 4 times, leaving a remainder of 62.
The next digit of our result is 4. 
Result so far: 4.0
Subtracting 360 from 422 leaves us with 62.
Grab the next digit (3) from the dividend, add it to 62, then carry on: 623 / 90

Step 4:
When dividing 623 by 90, we get 6 with a remainder of 83.
Put 6 as the next digit of the answer. 
Result so far: 46.0
The remainder is 83 after subtracting 540 from 623.
Fetch the next digit (5) from the dividend, attach it to 83 and continue: 835 / 90

Step 5:
When dividing 835 by 90, we get 9 with a remainder of 25.
Put 9 as the next digit of the answer. 
Result so far: 469.0
Subtracting 810 from 835 leaves us with 25.
Take the next digit (0) from the dividend and append it to 25, then repeat: 250 / 90

Advancing to step 6:
250 divided by 90 is 2 with a remainder of 70.
The number 2 becomes the next digit in our result. 
Result so far: 4692.0
Subtracting 180 from 250 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 7:
The number 90 fits into 700 7 times, leaving a remainder of 70.
The number 7 becomes the next digit in our result. 
Result so far: 4692.7
Subtract 630 from 700 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 8:
When dividing 700 by 90, we get 7 with a remainder of 70.
The number 7 becomes the next digit in our result. 
Result so far: 4692.77
If we take 630 away from 700, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

The final outcome is 4692.77, with a leftover of 0.07.
