We divide 42253611 by 90
Our goal is to divide 42253611 by 90.

On to step 1:
4 divided by 90 is 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 90

Step 2:
When dividing 42 by 90, we get 0 with a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 42 after subtracting 0 from 42.
Append the next digit (2) from the dividend to 42 and continue with: 422 / 90

Moving on to step 3:
When dividing 422 by 90, we get 4 with a remainder of 62.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 360 from 422, we get 62.
Bring next digit (5) of the dividend behind the 62 and repeat the process: 625 / 90

Advancing to step 4:
When dividing 625 by 90, we get 6 with a remainder of 85.
Record the quotient 6 as the next digit in the result. 
Result so far: 46.0
Subtracting 540 from 625 leaves us with 85.
Grab the next digit (3) from the dividend, add it to 85, then carry on: 853 / 90

Step 5:
90 goes into 853 9 times with a remainder of 43.
Record the quotient 9 as the next digit in the result. 
Result so far: 469.0
The remainder is 43 after subtracting 810 from 853.
Append the next digit (6) from the dividend to 43 and continue with: 436 / 90

Going ahead to step 6:
When dividing 436 by 90, we get 4 with a remainder of 76.
The number 4 becomes the next digit in our result. 
Result so far: 4694.0
If we subtract 360 from 436, we get 76.
Grab the next digit (1) from the dividend, add it to 76, then carry on: 761 / 90

Moving on to step 7:
If we divide 761 by 90, we get 8 and a remainder of 41.
Put 8 as the next digit of the answer. 
Result so far: 46948.0
If we subtract 720 from 761, we get 41.
Append the next digit (1) from the dividend to 41 and continue with: 411 / 90

Let's proceed to step 8:
When dividing 411 by 90, we get 4 with a remainder of 51.
Use 4 as the next digit of our solution. 
Result so far: 469484.0
If we take 360 away from 411, we end up with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Let's proceed to step 9:
90 can be fit into 510 5 times, resulting in a remainder of 60.
Put 5 as the next digit of the answer. 
Result so far: 469484.5
Deduct 450 from 510 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 10:
When dividing 600 by 90, we get 6 with a remainder of 60.
Put 6 as the next digit of the answer. 
Result so far: 469484.56
The remainder is 60 after subtracting 540 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 11:
90 can be fit into 600 6 times, resulting in a remainder of 60.
The next digit of our result is 6. 
Result so far: 469484.566
The remainder is 60 after subtracting 540 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

The final outcome is 469484.566, with a leftover of 0.006.
