We look at the division of 7290021 by 750 
We want to figure out the number of times 7290021 can be divided by 750.

Advancing to step 1:
750 can be fit into 7 0 times, resulting in a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 750

On to step 2:
When dividing 72 by 750, we get 0 with a remainder of 72.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 72 to get 72.
Take the next digit (9) from the dividend and append it to 72, then repeat: 729 / 750

Step 3:
750 goes into 729 0 times with a remainder of 729.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 729, we get 729.
Fetch the next digit (0) from the dividend, attach it to 729 and continue: 7290 / 750

Advancing to step 4:
7290 divided by 750 is 9 with a remainder of 540.
Write down 9 as next digit of the result. 
Result so far: 9.0
Deduct 6750 from 7290 and we're left with 540.
Take the next digit (0) from the dividend and append it to 540, then repeat: 5400 / 750

Step 5:
When dividing 5400 by 750, we get 7 with a remainder of 150.
The number 7 becomes the next digit in our result. 
Result so far: 97.0
Subtracting 5250 from 5400 leaves us with 150.
Bring next digit (2) of the dividend behind the 150 and repeat the process: 1502 / 750

Advancing to step 6:
When dividing 1502 by 750, we get 2 with a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 972.0
If we take 1500 away from 1502, we end up with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 750

Step 7:
750 can be fit into 21 0 times, resulting in a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 9720.0
If we take 0 away from 21, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 8:
The number 750 fits into 210 0 times, leaving a remainder of 210.
Use 0 as the next digit of our solution. 
Result so far: 9720.0
If we subtract 0 from 210, we get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Advancing to step 9:
When dividing 2100 by 750, we get 2 with a remainder of 600.
Use 2 as the next digit of our solution. 
Result so far: 9720.02
Subtracting 1500 from 2100 leaves us with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Step 10:
When dividing 6000 by 750, we get 8 with a remainder of 0.
The next digit of our result is 8. 
Result so far: 9720.028
If we subtract 6000 from 6000, 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.

Let's proceed to step 11:
The number 750 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 9720.028
Subtracting 0 from 0 leaves us 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.

On to step 12:
If we divide 0 by 750, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 9720.028
The remainder is 0 after subtracting 0 from 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 9720.028 with a remaining 0.0.
