We're dividing 3400125 by 75 
We want to figure out the number of times 3400125 can be divided by 75.

Step 1:
3 divided by 75 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 75

Going ahead to step 2:
If we divide 34 by 75, we get 0 and a remainder of 34.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 34, we end up with 34.
Grab the next digit (0) from the dividend, add it to 34, then carry on: 340 / 75

Advancing to step 3:
340 divided by 75 is 4 with a remainder of 40.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
The remainder is 40 after subtracting 300 from 340.
Bring next digit (0) of the dividend behind the 40 and repeat the process: 400 / 75

Advancing to step 4:
75 goes into 400 5 times with a remainder of 25.
The next digit of our result is 5. 
Result so far: 45.0
Subtract 375 from 400 to get 25.
Grab the next digit (1) from the dividend, add it to 25, then carry on: 251 / 75

On to step 5:
75 goes into 251 3 times with a remainder of 26.
Write down 3 as next digit of the result. 
Result so far: 453.0
Subtract 225 from 251 to get 26.
Grab the next digit (2) from the dividend, add it to 26, then carry on: 262 / 75

Moving on to step 6:
The number 75 fits into 262 3 times, leaving a remainder of 37.
Write down 3 as next digit of the result. 
Result so far: 4533.0
The remainder is 37 after subtracting 225 from 262.
Grab the next digit (5) from the dividend, add it to 37, then carry on: 375 / 75

Going ahead to step 7:
If we divide 375 by 75, we get 5 and a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 45335.0
The remainder is 0 after subtracting 375 from 375.
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 8:
When dividing 0 by 75, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 45335.0
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.

Going ahead to step 9:
75 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 45335.0
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.

The final outcome is 45335.0, with a leftover of 0.0.
