89134531 ÷ 72 
We're looking to find how many times 72 goes into 89134531.

On to step 1:
The number 72 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (9) from the dividend, attach it to 8 and continue: 89 / 72

Going ahead to step 2:
72 goes into 89 1 times with a remainder of 17.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 72 away from 89, we end up with 17.
Include the next digit (1) from the dividend after 17, then repeat: 171 / 72

Let's proceed to step 3:
If we divide 171 by 72, we get 2 and a remainder of 27.
Write down 2 as next digit of the result. 
Result so far: 12.0
Deduct 144 from 171 and we're left with 27.
Include the next digit (3) from the dividend after 27, then repeat: 273 / 72

Advancing to step 4:
If we divide 273 by 72, we get 3 and a remainder of 57.
The number 3 becomes the next digit in our result. 
Result so far: 123.0
If we take 216 away from 273, we end up with 57.
Append the next digit (4) from the dividend to 57 and continue with: 574 / 72

On to step 5:
72 goes into 574 7 times with a remainder of 70.
Put 7 as the next digit of the answer. 
Result so far: 1237.0
Subtracting 504 from 574 leaves us with 70.
Fetch the next digit (5) from the dividend, attach it to 70 and continue: 705 / 72

On to step 6:
When dividing 705 by 72, we get 9 with a remainder of 57.
Use 9 as the next digit of our solution. 
Result so far: 12379.0
Subtracting 648 from 705 leaves us with 57.
Grab the next digit (3) from the dividend, add it to 57, then carry on: 573 / 72

Moving on to step 7:
72 goes into 573 7 times with a remainder of 69.
Use 7 as the next digit of our solution. 
Result so far: 123797.0
Subtracting 504 from 573 leaves us with 69.
Bring next digit (1) of the dividend behind the 69 and repeat the process: 691 / 72

Moving on to step 8:
If we divide 691 by 72, we get 9 and a remainder of 43.
Put 9 as the next digit of the answer. 
Result so far: 1237979.0
Subtracting 648 from 691 leaves us with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Going ahead to step 9:
The number 72 fits into 430 5 times, leaving a remainder of 70.
Use 5 as the next digit of our solution. 
Result so far: 1237979.5
Subtracting 360 from 430 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 10:
The number 72 fits into 700 9 times, leaving a remainder of 52.
Use 9 as the next digit of our solution. 
Result so far: 1237979.59
If we subtract 648 from 700, 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.

On to step 11:
520 divided by 72 is 7 with a remainder of 16.
The next digit of our result is 7. 
Result so far: 1237979.597
Deduct 504 from 520 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.

Step 12:
The number 72 fits into 160 2 times, leaving a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 1237979.5972
Subtracting 144 from 160 leaves us 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 13:
The number 72 fits into 160 2 times, leaving a remainder of 16.
The next digit of our result is 2. 
Result so far: 1237979.59722
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.

In conclusion, the division gives 1237979.59722 with a balance of 1.6e-05.
