7145025 divided by 39 
We want to figure out the number of times 7145025 can be divided by 39.

Step 1:
7 divided by 39 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (1) from the dividend, attach it to 7 and continue: 71 / 39

Step 2:
If we divide 71 by 39, we get 1 and a remainder of 32.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 39 away from 71, we end up with 32.
Take the next digit (4) from the dividend and append it to 32, then repeat: 324 / 39

Advancing to step 3:
39 goes into 324 8 times with a remainder of 12.
The next digit of our result is 8. 
Result so far: 18.0
The remainder is 12 after subtracting 312 from 324.
Fetch the next digit (5) from the dividend, attach it to 12 and continue: 125 / 39

Let's proceed to step 4:
39 can be fit into 125 3 times, resulting in a remainder of 8.
The next digit of our result is 3. 
Result so far: 183.0
Subtracting 117 from 125 leaves us with 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 39

Moving on to step 5:
The number 39 fits into 80 2 times, leaving a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 1832.0
If we subtract 78 from 80, we get 2.
Append the next digit (2) from the dividend to 2 and continue with: 22 / 39

Let's proceed to step 6:
When dividing 22 by 39, we get 0 with a remainder of 22.
Use 0 as the next digit of our solution. 
Result so far: 18320.0
If we subtract 0 from 22, we get 22.
Bring next digit (5) of the dividend behind the 22 and repeat the process: 225 / 39

Going ahead to step 7:
If we divide 225 by 39, we get 5 and a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 183205.0
If we subtract 195 from 225, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 8:
39 can be fit into 300 7 times, resulting in a remainder of 27.
Record the quotient 7 as the next digit in the result. 
Result so far: 183205.7
Deduct 273 from 300 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 9:
If we divide 270 by 39, we get 6 and a remainder of 36.
The next digit of our result is 6. 
Result so far: 183205.76
Subtracting 234 from 270 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 10:
39 can be fit into 360 9 times, resulting in a remainder of 9.
The next digit of our result is 9. 
Result so far: 183205.769
Deduct 351 from 360 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 11:
39 goes into 90 2 times with a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 183205.7692
If we subtract 78 from 90, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 12:
If we divide 120 by 39, we get 3 and a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 183205.76923
If we subtract 117 from 120, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 13:
39 goes into 30 0 times with a remainder of 30.
The next digit of our result is 0. 
Result so far: 183205.76923
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 14:
When dividing 300 by 39, we get 7 with a remainder of 27.
The next digit of our result is 7. 
Result so far: 183205.7692307
If we subtract 273 from 300, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 15:
When dividing 270 by 39, we get 6 with a remainder of 36.
Write down 6 as next digit of the result. 
Result so far: 183205.76923076
Deduct 234 from 270 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

In conclusion, the division gives 183205.76923076 with a balance of 3.6e-08.
