Let's divide 78671309 by 625
We want to divide 78671309 by 625.

Advancing to step 1:
7 divided by 625 is 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 625

Step 2:
The number 625 fits into 78 0 times, leaving a remainder of 78.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 78 after subtracting 0 from 78.
Append the next digit (6) from the dividend to 78 and continue with: 786 / 625

Let's proceed to step 3:
The number 625 fits into 786 1 times, leaving a remainder of 161.
The next digit of our result is 1. 
Result so far: 1.0
If we take 625 away from 786, we end up with 161.
Take the next digit (7) from the dividend and append it to 161, then repeat: 1617 / 625

Going ahead to step 4:
When dividing 1617 by 625, we get 2 with a remainder of 367.
Use 2 as the next digit of our solution. 
Result so far: 12.0
If we subtract 1250 from 1617, we get 367.
Include the next digit (1) from the dividend after 367, then repeat: 3671 / 625

Step 5:
3671 divided by 625 is 5 with a remainder of 546.
Write down 5 as next digit of the result. 
Result so far: 125.0
Subtracting 3125 from 3671 leaves us with 546.
Append the next digit (3) from the dividend to 546 and continue with: 5463 / 625

Advancing to step 6:
If we divide 5463 by 625, we get 8 and a remainder of 463.
Put 8 as the next digit of the answer. 
Result so far: 1258.0
Deduct 5000 from 5463 and we're left with 463.
Append the next digit (0) from the dividend to 463 and continue with: 4630 / 625

Let's proceed to step 7:
When dividing 4630 by 625, we get 7 with a remainder of 255.
Write down 7 as next digit of the result. 
Result so far: 12587.0
Subtract 4375 from 4630 to get 255.
Fetch the next digit (9) from the dividend, attach it to 255 and continue: 2559 / 625

Step 8:
When dividing 2559 by 625, we get 4 with a remainder of 59.
Put 4 as the next digit of the answer. 
Result so far: 125874.0
Deduct 2500 from 2559 and we're left with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

On to step 9:
590 divided by 625 is 0 with a remainder of 590.
Use 0 as the next digit of our solution. 
Result so far: 125874.0
If we subtract 0 from 590, we get 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

Moving on to step 10:
625 can be fit into 5900 9 times, resulting in a remainder of 275.
Put 9 as the next digit of the answer. 
Result so far: 125874.09
Deduct 5625 from 5900 and we're left with 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

On to step 11:
2750 divided by 625 is 4 with a remainder of 250.
Use 4 as the next digit of our solution. 
Result so far: 125874.094
The remainder is 250 after subtracting 2500 from 2750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Going ahead to step 12:
625 can be fit into 2500 4 times, resulting in a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 125874.0944
Subtract 2500 from 2500 to get 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 125874.0944, with a leftover of 0.0.
