51003370 ÷ 75 
We're looking to find how many times 75 goes into 51003370.

On to step 1:
5 divided by 75 is 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 75

Going ahead to step 2:
If we divide 51 by 75, we get 0 and a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 51 and we're left with 51.
Fetch the next digit (0) from the dividend, attach it to 51 and continue: 510 / 75

Advancing to step 3:
If we divide 510 by 75, we get 6 and a remainder of 60.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we take 450 away from 510, we end up with 60.
Include the next digit (0) from the dividend after 60, then repeat: 600 / 75

Let's proceed to step 4:
600 divided by 75 is 8 with a remainder of 0.
The next digit of our result is 8. 
Result so far: 68.0
Deduct 600 from 600 and we're left with 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 75

Moving on to step 5:
When dividing 3 by 75, we get 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 680.0
If we subtract 0 from 3, we get 3.
Include the next digit (3) from the dividend after 3, then repeat: 33 / 75

Step 6:
When dividing 33 by 75, we get 0 with a remainder of 33.
The number 0 becomes the next digit in our result. 
Result so far: 6800.0
Subtract 0 from 33 to get 33.
Append the next digit (7) from the dividend to 33 and continue with: 337 / 75

Let's proceed to step 7:
The number 75 fits into 337 4 times, leaving a remainder of 37.
Use 4 as the next digit of our solution. 
Result so far: 68004.0
Deduct 300 from 337 and we're left with 37.
Grab the next digit (0) from the dividend, add it to 37, then carry on: 370 / 75

On to step 8:
The number 75 fits into 370 4 times, leaving a remainder of 70.
The number 4 becomes the next digit in our result. 
Result so far: 680044.0
Subtract 300 from 370 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 9:
75 goes into 700 9 times with a remainder of 25.
Record the quotient 9 as the next digit in the result. 
Result so far: 680044.9
If we subtract 675 from 700, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 10:
When dividing 250 by 75, we get 3 with a remainder of 25.
Use 3 as the next digit of our solution. 
Result so far: 680044.93
If we subtract 225 from 250, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 11:
75 can be fit into 250 3 times, resulting in a remainder of 25.
Record the quotient 3 as the next digit in the result. 
Result so far: 680044.933
If we subtract 225 from 250, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Our division results in 680044.933 with a remaining 0.0025.
