We're dividing 100310 by 72 
Let's see how many times 72 fits into 100310.

Advancing to step 1:
72 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 72

Moving on to step 2:
If we divide 10 by 72, we get 0 and a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 10 to get 10.
Fetch the next digit (0) from the dividend, attach it to 10 and continue: 100 / 72

Moving on to step 3:
The number 72 fits into 100 1 times, leaving a remainder of 28.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 72 from 100 leaves us with 28.
Take the next digit (3) from the dividend and append it to 28, then repeat: 283 / 72

Step 4:
72 goes into 283 3 times with a remainder of 67.
The next digit of our result is 3. 
Result so far: 13.0
If we subtract 216 from 283, we get 67.
Bring next digit (1) of the dividend behind the 67 and repeat the process: 671 / 72

Let's proceed to step 5:
The number 72 fits into 671 9 times, leaving a remainder of 23.
Write down 9 as next digit of the result. 
Result so far: 139.0
Subtracting 648 from 671 leaves us with 23.
Take the next digit (0) from the dividend and append it to 23, then repeat: 230 / 72

Let's proceed to step 6:
230 divided by 72 is 3 with a remainder of 14.
Record the quotient 3 as the next digit in the result. 
Result so far: 1393.0
Subtract 216 from 230 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 7:
140 divided by 72 is 1 with a remainder of 68.
Record the quotient 1 as the next digit in the result. 
Result so far: 1393.1
If we subtract 72 from 140, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

On to step 8:
680 divided by 72 is 9 with a remainder of 32.
Record the quotient 9 as the next digit in the result. 
Result so far: 1393.19
If we take 648 away from 680, we end up 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.

Moving on to step 9:
72 can be fit into 320 4 times, resulting in a remainder of 32.
Use 4 as the next digit of our solution. 
Result so far: 1393.194
If we take 288 away from 320, we end up 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.

Advancing to step 10:
If we divide 320 by 72, we get 4 and a remainder of 32.
Record the quotient 4 as the next digit in the result. 
Result so far: 1393.1944
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 1393.1944 with a balance of 0.00032.
