We're dividing 78964380 by 625 
We're looking to find how many times 625 goes into 78964380.

Moving on to step 1:
If we divide 7 by 625, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 625

Moving on to step 2:
625 goes into 78 0 times with a remainder of 78.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 78 to get 78.
Fetch the next digit (9) from the dividend, attach it to 78 and continue: 789 / 625

Going ahead to step 3:
625 can be fit into 789 1 times, resulting in a remainder of 164.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 625 from 789, we get 164.
Bring next digit (6) of the dividend behind the 164 and repeat the process: 1646 / 625

Moving on to step 4:
1646 divided by 625 is 2 with a remainder of 396.
Write down 2 as next digit of the result. 
Result so far: 12.0
Subtract 1250 from 1646 to get 396.
Append the next digit (4) from the dividend to 396 and continue with: 3964 / 625

Let's proceed to step 5:
3964 divided by 625 is 6 with a remainder of 214.
The next digit of our result is 6. 
Result so far: 126.0
If we subtract 3750 from 3964, we get 214.
Bring next digit (3) of the dividend behind the 214 and repeat the process: 2143 / 625

Going ahead to step 6:
2143 divided by 625 is 3 with a remainder of 268.
Record the quotient 3 as the next digit in the result. 
Result so far: 1263.0
The remainder is 268 after subtracting 1875 from 2143.
Grab the next digit (8) from the dividend, add it to 268, then carry on: 2688 / 625

On to step 7:
625 can be fit into 2688 4 times, resulting in a remainder of 188.
The next digit of our result is 4. 
Result so far: 12634.0
Deduct 2500 from 2688 and we're left with 188.
Bring next digit (0) of the dividend behind the 188 and repeat the process: 1880 / 625

Advancing to step 8:
When dividing 1880 by 625, we get 3 with a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 126343.0
The remainder is 5 after subtracting 1875 from 1880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 9:
625 can be fit into 50 0 times, resulting in a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 126343.0
If we take 0 away from 50, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 10:
If we divide 500 by 625, we get 0 and a remainder of 500.
The next digit of our result is 0. 
Result so far: 126343.0
Subtract 0 from 500 to get 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

The final result is 126343.0 with a remainder of 0.5.
