We look at the division of 78503300 by 145 
Our goal is to divide 78503300 by 145.

Let's proceed to step 1:
If we divide 7 by 145, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 145

Moving on to step 2:
When dividing 78 by 145, we get 0 with a remainder of 78.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 78, we end up with 78.
Grab the next digit (5) from the dividend, add it to 78, then carry on: 785 / 145

Moving on to step 3:
If we divide 785 by 145, we get 5 and a remainder of 60.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtract 725 from 785 to get 60.
Bring next digit (0) of the dividend behind the 60 and repeat the process: 600 / 145

Advancing to step 4:
145 goes into 600 4 times with a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 54.0
Subtract 580 from 600 to get 20.
Fetch the next digit (3) from the dividend, attach it to 20 and continue: 203 / 145

Step 5:
145 goes into 203 1 times with a remainder of 58.
The number 1 becomes the next digit in our result. 
Result so far: 541.0
Deduct 145 from 203 and we're left with 58.
Grab the next digit (3) from the dividend, add it to 58, then carry on: 583 / 145

Moving on to step 6:
145 goes into 583 4 times with a remainder of 3.
Put 4 as the next digit of the answer. 
Result so far: 5414.0
Subtract 580 from 583 to get 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 145

Advancing to step 7:
The number 145 fits into 30 0 times, leaving a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 54140.0
Subtract 0 from 30 to get 30.
Grab the next digit (0) from the dividend, add it to 30, then carry on: 300 / 145

Going ahead to step 8:
If we divide 300 by 145, we get 2 and a remainder of 10.
Write down 2 as next digit of the result. 
Result so far: 541402.0
Subtract 290 from 300 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 9:
145 can be fit into 100 0 times, resulting in a remainder of 100.
Put 0 as the next digit of the answer. 
Result so far: 541402.0
Deduct 0 from 100 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Let's proceed to step 10:
The number 145 fits into 1000 6 times, leaving a remainder of 130.
Use 6 as the next digit of our solution. 
Result so far: 541402.06
If we subtract 870 from 1000, we get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

On to step 11:
The number 145 fits into 1300 8 times, leaving a remainder of 140.
Record the quotient 8 as the next digit in the result. 
Result so far: 541402.068
If we subtract 1160 from 1300, we get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Moving on to step 12:
When dividing 1400 by 145, we get 9 with a remainder of 95.
Write down 9 as next digit of the result. 
Result so far: 541402.0689
The remainder is 95 after subtracting 1305 from 1400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

On to step 13:
If we divide 950 by 145, we get 6 and a remainder of 80.
The next digit of our result is 6. 
Result so far: 541402.06896
If we subtract 870 from 950, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 14:
145 can be fit into 800 5 times, resulting in a remainder of 75.
Write down 5 as next digit of the result. 
Result so far: 541402.068965
If we subtract 725 from 800, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Going ahead to step 15:
145 can be fit into 750 5 times, resulting in a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 541402.0689655
If we subtract 725 from 750, 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 541402.0689655 with a remaining 2.5e-07.
