We divide 90253959 by 100
Let's see how many times 100 fits into 90253959.

On to step 1:
100 can be fit into 9 0 times, resulting in a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 100

On to step 2:
When dividing 90 by 100, we get 0 with a remainder of 90.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 90 to get 90.
Append the next digit (2) from the dividend to 90 and continue with: 902 / 100

On to step 3:
If we divide 902 by 100, we get 9 and a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtract 900 from 902 to get 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 100

Advancing to step 4:
100 goes into 25 0 times with a remainder of 25.
Put 0 as the next digit of the answer. 
Result so far: 90.0
Subtracting 0 from 25 leaves us with 25.
Take the next digit (3) from the dividend and append it to 25, then repeat: 253 / 100

On to step 5:
The number 100 fits into 253 2 times, leaving a remainder of 53.
The number 2 becomes the next digit in our result. 
Result so far: 902.0
The remainder is 53 after subtracting 200 from 253.
Take the next digit (9) from the dividend and append it to 53, then repeat: 539 / 100

Moving on to step 6:
100 goes into 539 5 times with a remainder of 39.
Write down 5 as next digit of the result. 
Result so far: 9025.0
Deduct 500 from 539 and we're left with 39.
Take the next digit (5) from the dividend and append it to 39, then repeat: 395 / 100

Going ahead to step 7:
395 divided by 100 is 3 with a remainder of 95.
Put 3 as the next digit of the answer. 
Result so far: 90253.0
If we take 300 away from 395, we end up with 95.
Append the next digit (9) from the dividend to 95 and continue with: 959 / 100

Advancing to step 8:
959 divided by 100 is 9 with a remainder of 59.
Write down 9 as next digit of the result. 
Result so far: 902539.0
If we subtract 900 from 959, we get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

On to step 9:
100 can be fit into 590 5 times, resulting in a remainder of 90.
Record the quotient 5 as the next digit in the result. 
Result so far: 902539.5
If we subtract 500 from 590, we get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

On to step 10:
If we divide 900 by 100, we get 9 and a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 902539.59
If we subtract 900 from 900, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 11:
0 divided by 100 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 902539.59
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 12:
The number 100 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 902539.59
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 902539.59 with a balance of 0.0.
