We look at the division of 315630 by 72 
We want to figure out the number of times 315630 can be divided by 72.

Moving on to step 1:
The number 72 fits into 3 0 times, leaving a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 72

Let's proceed to step 2:
When dividing 31 by 72, we get 0 with a remainder of 31.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 31 after subtracting 0 from 31.
Take the next digit (5) from the dividend and append it to 31, then repeat: 315 / 72

Let's proceed to step 3:
72 can be fit into 315 4 times, resulting in a remainder of 27.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtracting 288 from 315 leaves us with 27.
Grab the next digit (6) from the dividend, add it to 27, then carry on: 276 / 72

Advancing to step 4:
72 goes into 276 3 times with a remainder of 60.
The number 3 becomes the next digit in our result. 
Result so far: 43.0
Deduct 216 from 276 and we're left with 60.
Grab the next digit (3) from the dividend, add it to 60, then carry on: 603 / 72

Let's proceed to step 5:
When dividing 603 by 72, we get 8 with a remainder of 27.
Use 8 as the next digit of our solution. 
Result so far: 438.0
If we take 576 away from 603, we end up with 27.
Include the next digit (0) from the dividend after 27, then repeat: 270 / 72

Moving on to step 6:
If we divide 270 by 72, we get 3 and a remainder of 54.
Use 3 as the next digit of our solution. 
Result so far: 4383.0
The remainder is 54 after subtracting 216 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 7:
72 can be fit into 540 7 times, resulting in a remainder of 36.
Use 7 as the next digit of our solution. 
Result so far: 4383.7
The remainder is 36 after subtracting 504 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 8:
The number 72 fits into 360 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 4383.75
If we take 360 away from 360, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 9:
72 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 4383.75
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 10:
If we divide 0 by 72, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 4383.75
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 4383.75 with a remaining 0.0.
