We look at the division of 45189003 by 78 
We're looking to find how many times 78 goes into 45189003.

Advancing to step 1:
If we divide 4 by 78, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 78

Let's proceed to step 2:
When dividing 45 by 78, we get 0 with a remainder of 45.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 45 to get 45.
Append the next digit (1) from the dividend to 45 and continue with: 451 / 78

Moving on to step 3:
When dividing 451 by 78, we get 5 with a remainder of 61.
Write down 5 as next digit of the result. 
Result so far: 5.0
If we subtract 390 from 451, we get 61.
Grab the next digit (8) from the dividend, add it to 61, then carry on: 618 / 78

Advancing to step 4:
When dividing 618 by 78, we get 7 with a remainder of 72.
The next digit of our result is 7. 
Result so far: 57.0
If we take 546 away from 618, we end up with 72.
Append the next digit (9) from the dividend to 72 and continue with: 729 / 78

Step 5:
78 can be fit into 729 9 times, resulting in a remainder of 27.
Write down 9 as next digit of the result. 
Result so far: 579.0
Subtract 702 from 729 to get 27.
Grab the next digit (0) from the dividend, add it to 27, then carry on: 270 / 78

Advancing to step 6:
78 goes into 270 3 times with a remainder of 36.
Write down 3 as next digit of the result. 
Result so far: 5793.0
The remainder is 36 after subtracting 234 from 270.
Fetch the next digit (0) from the dividend, attach it to 36 and continue: 360 / 78

Step 7:
360 divided by 78 is 4 with a remainder of 48.
Put 4 as the next digit of the answer. 
Result so far: 57934.0
If we take 312 away from 360, we end up with 48.
Grab the next digit (3) from the dividend, add it to 48, then carry on: 483 / 78

Advancing to step 8:
When dividing 483 by 78, we get 6 with a remainder of 15.
Put 6 as the next digit of the answer. 
Result so far: 579346.0
If we subtract 468 from 483, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 9:
150 divided by 78 is 1 with a remainder of 72.
The next digit of our result is 1. 
Result so far: 579346.1
Deduct 78 from 150 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 10:
78 can be fit into 720 9 times, resulting in a remainder of 18.
Put 9 as the next digit of the answer. 
Result so far: 579346.19
If we take 702 away from 720, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 11:
If we divide 180 by 78, we get 2 and a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 579346.192
If we take 156 away from 180, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 12:
If we divide 240 by 78, we get 3 and a remainder of 6.
The next digit of our result is 3. 
Result so far: 579346.1923
Subtract 234 from 240 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 13:
78 can be fit into 60 0 times, resulting in a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 579346.1923
Subtracting 0 from 60 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 14:
78 goes into 600 7 times with a remainder of 54.
Use 7 as the next digit of our solution. 
Result so far: 579346.192307
If we take 546 away from 600, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

On to step 15:
78 can be fit into 540 6 times, resulting in a remainder of 72.
Write down 6 as next digit of the result. 
Result so far: 579346.1923076
Deduct 468 from 540 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 16:
78 can be fit into 720 9 times, resulting in a remainder of 18.
Use 9 as the next digit of our solution. 
Result so far: 579346.19230769
If we take 702 away from 720, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

After the division, we end up with 579346.19230769 and a remainder of 1.8e-08.
