90668216 divided by 72 
We want to figure out the number of times 90668216 can be divided by 72.

On to step 1:
72 goes into 9 0 times with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 72

On to step 2:
If we divide 90 by 72, we get 1 and a remainder of 18.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 72 from 90, we get 18.
Fetch the next digit (6) from the dividend, attach it to 18 and continue: 186 / 72

Let's proceed to step 3:
72 can be fit into 186 2 times, resulting in a remainder of 42.
The next digit of our result is 2. 
Result so far: 12.0
Deduct 144 from 186 and we're left with 42.
Append the next digit (6) from the dividend to 42 and continue with: 426 / 72

On to step 4:
The number 72 fits into 426 5 times, leaving a remainder of 66.
Record the quotient 5 as the next digit in the result. 
Result so far: 125.0
The remainder is 66 after subtracting 360 from 426.
Fetch the next digit (8) from the dividend, attach it to 66 and continue: 668 / 72

Let's proceed to step 5:
668 divided by 72 is 9 with a remainder of 20.
The next digit of our result is 9. 
Result so far: 1259.0
If we subtract 648 from 668, we get 20.
Include the next digit (2) from the dividend after 20, then repeat: 202 / 72

Moving on to step 6:
72 goes into 202 2 times with a remainder of 58.
The next digit of our result is 2. 
Result so far: 12592.0
If we subtract 144 from 202, we get 58.
Include the next digit (1) from the dividend after 58, then repeat: 581 / 72

Going ahead to step 7:
72 can be fit into 581 8 times, resulting in a remainder of 5.
The number 8 becomes the next digit in our result. 
Result so far: 125928.0
If we subtract 576 from 581, we get 5.
Fetch the next digit (6) from the dividend, attach it to 5 and continue: 56 / 72

On to step 8:
72 can be fit into 56 0 times, resulting in a remainder of 56.
Use 0 as the next digit of our solution. 
Result so far: 1259280.0
Subtract 0 from 56 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 9:
72 can be fit into 560 7 times, resulting in a remainder of 56.
Record the quotient 7 as the next digit in the result. 
Result so far: 1259280.7
The remainder is 56 after subtracting 504 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 10:
72 can be fit into 560 7 times, resulting in a remainder of 56.
Record the quotient 7 as the next digit in the result. 
Result so far: 1259280.77
Subtract 504 from 560 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

In conclusion, the division gives 1259280.77 with a balance of 0.056.
