90711493 divided by 72 
We want to figure out the number of times 90711493 can be divided by 72.

Moving on to step 1:
The number 72 fits into 9 0 times, leaving a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 72

Step 2:
The number 72 fits into 90 1 times, leaving a remainder of 18.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 72 from 90 and we're left with 18.
Fetch the next digit (7) from the dividend, attach it to 18 and continue: 187 / 72

Let's proceed to step 3:
72 can be fit into 187 2 times, resulting in a remainder of 43.
Put 2 as the next digit of the answer. 
Result so far: 12.0
The remainder is 43 after subtracting 144 from 187.
Take the next digit (1) from the dividend and append it to 43, then repeat: 431 / 72

Step 4:
When dividing 431 by 72, we get 5 with a remainder of 71.
Write down 5 as next digit of the result. 
Result so far: 125.0
Subtract 360 from 431 to get 71.
Include the next digit (1) from the dividend after 71, then repeat: 711 / 72

Advancing to step 5:
If we divide 711 by 72, we get 9 and a remainder of 63.
Record the quotient 9 as the next digit in the result. 
Result so far: 1259.0
Deduct 648 from 711 and we're left with 63.
Include the next digit (4) from the dividend after 63, then repeat: 634 / 72

Moving on to step 6:
If we divide 634 by 72, we get 8 and a remainder of 58.
The number 8 becomes the next digit in our result. 
Result so far: 12598.0
The remainder is 58 after subtracting 576 from 634.
Include the next digit (9) from the dividend after 58, then repeat: 589 / 72

Step 7:
72 goes into 589 8 times with a remainder of 13.
The number 8 becomes the next digit in our result. 
Result so far: 125988.0
If we take 576 away from 589, we end up with 13.
Include the next digit (3) from the dividend after 13, then repeat: 133 / 72

Going ahead to step 8:
When dividing 133 by 72, we get 1 with a remainder of 61.
Put 1 as the next digit of the answer. 
Result so far: 1259881.0
The remainder is 61 after subtracting 72 from 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Let's proceed to step 9:
72 can be fit into 610 8 times, resulting in a remainder of 34.
Record the quotient 8 as the next digit in the result. 
Result so far: 1259881.8
If we take 576 away from 610, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 10:
72 can be fit into 340 4 times, resulting in a remainder of 52.
The next digit of our result is 4. 
Result so far: 1259881.84
If we subtract 288 from 340, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 11:
520 divided by 72 is 7 with a remainder of 16.
Put 7 as the next digit of the answer. 
Result so far: 1259881.847
If we take 504 away from 520, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 12:
The number 72 fits into 160 2 times, leaving a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 1259881.8472
If we subtract 144 from 160, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 13:
72 can be fit into 160 2 times, resulting in a remainder of 16.
The next digit of our result is 2. 
Result so far: 1259881.84722
Deduct 144 from 160 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

After the division, we end up with 1259881.84722 and a remainder of 1.6e-05.
