91510628 ÷ 72 
Our goal is to divide 91510628 by 72.

Step 1:
9 divided by 72 is 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 72

Step 2:
91 divided by 72 is 1 with a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 72 from 91 to get 19.
Append the next digit (5) from the dividend to 19 and continue with: 195 / 72

Let's proceed to step 3:
195 divided by 72 is 2 with a remainder of 51.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
The remainder is 51 after subtracting 144 from 195.
Include the next digit (1) from the dividend after 51, then repeat: 511 / 72

Advancing to step 4:
72 goes into 511 7 times with a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 127.0
If we take 504 away from 511, we end up with 7.
Take the next digit (0) from the dividend and append it to 7, then repeat: 70 / 72

On to step 5:
When dividing 70 by 72, we get 0 with a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 1270.0
Deduct 0 from 70 and we're left with 70.
Take the next digit (6) from the dividend and append it to 70, then repeat: 706 / 72

Step 6:
If we divide 706 by 72, we get 9 and a remainder of 58.
Put 9 as the next digit of the answer. 
Result so far: 12709.0
Subtracting 648 from 706 leaves us with 58.
Bring next digit (2) of the dividend behind the 58 and repeat the process: 582 / 72

Advancing to step 7:
When dividing 582 by 72, we get 8 with a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 127098.0
Subtract 576 from 582 to get 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 72

Going ahead to step 8:
When dividing 68 by 72, we get 0 with a remainder of 68.
Use 0 as the next digit of our solution. 
Result so far: 1270980.0
If we take 0 away from 68, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 9:
If we divide 680 by 72, we get 9 and a remainder of 32.
Put 9 as the next digit of the answer. 
Result so far: 1270980.9
Deduct 648 from 680 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 10:
The number 72 fits into 320 4 times, leaving a remainder of 32.
The next digit of our result is 4. 
Result so far: 1270980.94
The remainder is 32 after subtracting 288 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 11:
72 goes into 320 4 times with a remainder of 32.
Use 4 as the next digit of our solution. 
Result so far: 1270980.944
Subtract 288 from 320 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

In conclusion, the division gives 1270980.944 with a balance of 0.0032.
