Let's divide 72225700 by 515
Our goal is to divide 72225700 by 515.

Step 1:
When dividing 7 by 515, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 515

Let's proceed to step 2:
When dividing 72 by 515, we get 0 with a remainder of 72.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 72 to get 72.
Grab the next digit (2) from the dividend, add it to 72, then carry on: 722 / 515

Let's proceed to step 3:
The number 515 fits into 722 1 times, leaving a remainder of 207.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 515 from 722 and we're left with 207.
Grab the next digit (2) from the dividend, add it to 207, then carry on: 2072 / 515

Step 4:
515 goes into 2072 4 times with a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
If we subtract 2060 from 2072, we get 12.
Fetch the next digit (5) from the dividend, attach it to 12 and continue: 125 / 515

Advancing to step 5:
515 goes into 125 0 times with a remainder of 125.
Use 0 as the next digit of our solution. 
Result so far: 140.0
Subtract 0 from 125 to get 125.
Take the next digit (7) from the dividend and append it to 125, then repeat: 1257 / 515

Let's proceed to step 6:
If we divide 1257 by 515, we get 2 and a remainder of 227.
Record the quotient 2 as the next digit in the result. 
Result so far: 1402.0
If we take 1030 away from 1257, we end up with 227.
Take the next digit (0) from the dividend and append it to 227, then repeat: 2270 / 515

On to step 7:
The number 515 fits into 2270 4 times, leaving a remainder of 210.
The number 4 becomes the next digit in our result. 
Result so far: 14024.0
Deduct 2060 from 2270 and we're left with 210.
Grab the next digit (0) from the dividend, add it to 210, then carry on: 2100 / 515

On to step 8:
If we divide 2100 by 515, we get 4 and a remainder of 40.
The number 4 becomes the next digit in our result. 
Result so far: 140244.0
Deduct 2060 from 2100 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.

Advancing to step 9:
515 goes into 400 0 times with a remainder of 400.
Record the quotient 0 as the next digit in the result. 
Result so far: 140244.0
The remainder is 400 after subtracting 0 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Let's proceed to step 10:
When dividing 4000 by 515, we get 7 with a remainder of 395.
Write down 7 as next digit of the result. 
Result so far: 140244.07
The remainder is 395 after subtracting 3605 from 4000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3950, and continue the process.

On to step 11:
The number 515 fits into 3950 7 times, leaving a remainder of 345.
Put 7 as the next digit of the answer. 
Result so far: 140244.077
If we subtract 3605 from 3950, we get 345.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3450, and continue the process.

The quotient of the division is 140244.077, and the remainder is 0.0345.
