We're dividing 90360193 by 72 
We want to divide 90360193 by 72.

On to step 1:
When dividing 9 by 72, we get 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 72

Let's proceed to step 2:
72 can be fit into 90 1 times, resulting in a remainder of 18.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 72 from 90 and we're left with 18.
Fetch the next digit (3) from the dividend, attach it to 18 and continue: 183 / 72

On to step 3:
72 goes into 183 2 times with a remainder of 39.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Subtracting 144 from 183 leaves us with 39.
Include the next digit (6) from the dividend after 39, then repeat: 396 / 72

Step 4:
When dividing 396 by 72, we get 5 with a remainder of 36.
The number 5 becomes the next digit in our result. 
Result so far: 125.0
If we subtract 360 from 396, we get 36.
Take the next digit (0) from the dividend and append it to 36, then repeat: 360 / 72

Going ahead to step 5:
The number 72 fits into 360 5 times, leaving a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 1255.0
Deduct 360 from 360 and we're left with 0.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 72

On to step 6:
If we divide 1 by 72, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 12550.0
If we subtract 0 from 1, we get 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 72

Advancing to step 7:
72 can be fit into 19 0 times, resulting in a remainder of 19.
Use 0 as the next digit of our solution. 
Result so far: 125500.0
If we take 0 away from 19, we end up with 19.
Bring next digit (3) of the dividend behind the 19 and repeat the process: 193 / 72

Let's proceed to step 8:
If we divide 193 by 72, we get 2 and a remainder of 49.
Record the quotient 2 as the next digit in the result. 
Result so far: 1255002.0
If we take 144 away from 193, we end up with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Moving on to step 9:
72 can be fit into 490 6 times, resulting in a remainder of 58.
Record the quotient 6 as the next digit in the result. 
Result so far: 1255002.6
If we take 432 away from 490, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Going ahead to step 10:
580 divided by 72 is 8 with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 1255002.68
The remainder is 4 after subtracting 576 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 11:
The number 72 fits into 40 0 times, leaving a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 1255002.68
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 12:
If we divide 400 by 72, we get 5 and a remainder of 40.
Record the quotient 5 as the next digit in the result. 
Result so far: 1255002.6805
Subtracting 360 from 400 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 13:
If we divide 400 by 72, we get 5 and a remainder of 40.
The number 5 becomes the next digit in our result. 
Result so far: 1255002.68055
Deduct 360 from 400 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

In conclusion, the division gives 1255002.68055 with a balance of 4e-05.
