Let's divide 15540372 by 215
We want to figure out the number of times 15540372 can be divided by 215.

Let's proceed to step 1:
If we divide 1 by 215, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 215

Step 2:
215 goes into 15 0 times with a remainder of 15.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 15 after subtracting 0 from 15.
Bring next digit (5) of the dividend behind the 15 and repeat the process: 155 / 215

Advancing to step 3:
The number 215 fits into 155 0 times, leaving a remainder of 155.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 155 to get 155.
Append the next digit (4) from the dividend to 155 and continue with: 1554 / 215

Advancing to step 4:
215 can be fit into 1554 7 times, resulting in a remainder of 49.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Deduct 1505 from 1554 and we're left with 49.
Append the next digit (0) from the dividend to 49 and continue with: 490 / 215

Step 5:
490 divided by 215 is 2 with a remainder of 60.
Write down 2 as next digit of the result. 
Result so far: 72.0
Subtracting 430 from 490 leaves us with 60.
Take the next digit (3) from the dividend and append it to 60, then repeat: 603 / 215

Advancing to step 6:
215 goes into 603 2 times with a remainder of 173.
The number 2 becomes the next digit in our result. 
Result so far: 722.0
Deduct 430 from 603 and we're left with 173.
Take the next digit (7) from the dividend and append it to 173, then repeat: 1737 / 215

Moving on to step 7:
215 goes into 1737 8 times with a remainder of 17.
The next digit of our result is 8. 
Result so far: 7228.0
Subtract 1720 from 1737 to get 17.
Append the next digit (2) from the dividend to 17 and continue with: 172 / 215

Going ahead to step 8:
If we divide 172 by 215, we get 0 and a remainder of 172.
The number 0 becomes the next digit in our result. 
Result so far: 72280.0
If we take 0 away from 172, we end up with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Advancing to step 9:
When dividing 1720 by 215, we get 8 with a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 72280.8
Subtract 1720 from 1720 to get 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:
The number 215 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 72280.8
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.

Advancing to step 11:
215 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 72280.8
If we subtract 0 from 0, we get 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 72280.8 with a remaining 0.0.
