90035522 ÷ 221 
We want to figure out the number of times 90035522 can be divided by 221.

Let's proceed to step 1:
9 divided by 221 is 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 221

Going ahead to step 2:
221 can be fit into 90 0 times, resulting in a remainder of 90.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 90, we get 90.
Take the next digit (0) from the dividend and append it to 90, then repeat: 900 / 221

Moving on to step 3:
900 divided by 221 is 4 with a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 884 away from 900, we end up with 16.
Grab the next digit (3) from the dividend, add it to 16, then carry on: 163 / 221

Moving on to step 4:
221 goes into 163 0 times with a remainder of 163.
Use 0 as the next digit of our solution. 
Result so far: 40.0
The remainder is 163 after subtracting 0 from 163.
Fetch the next digit (5) from the dividend, attach it to 163 and continue: 1635 / 221

Going ahead to step 5:
221 can be fit into 1635 7 times, resulting in a remainder of 88.
Put 7 as the next digit of the answer. 
Result so far: 407.0
Subtracting 1547 from 1635 leaves us with 88.
Take the next digit (5) from the dividend and append it to 88, then repeat: 885 / 221

Let's proceed to step 6:
221 goes into 885 4 times with a remainder of 1.
Put 4 as the next digit of the answer. 
Result so far: 4074.0
If we take 884 away from 885, we end up with 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 221

On to step 7:
The number 221 fits into 12 0 times, leaving a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 40740.0
Subtract 0 from 12 to get 12.
Take the next digit (2) from the dividend and append it to 12, then repeat: 122 / 221

Step 8:
When dividing 122 by 221, we get 0 with a remainder of 122.
Write down 0 as next digit of the result. 
Result so far: 407400.0
The remainder is 122 after subtracting 0 from 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Step 9:
When dividing 1220 by 221, we get 5 with a remainder of 115.
Use 5 as the next digit of our solution. 
Result so far: 407400.5
Subtracting 1105 from 1220 leaves us with 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

On to step 10:
If we divide 1150 by 221, we get 5 and a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 407400.55
Subtracting 1105 from 1150 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

The final outcome is 407400.55, with a leftover of 0.045.
