We look at the division of 8743409 by 625 
We're looking to find how many times 625 goes into 8743409.

Advancing to step 1:
The number 625 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 625

Step 2:
625 goes into 87 0 times with a remainder of 87.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 87, we end up with 87.
Append the next digit (4) from the dividend to 87 and continue with: 874 / 625

Moving on to step 3:
874 divided by 625 is 1 with a remainder of 249.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 625 from 874 leaves us with 249.
Take the next digit (3) from the dividend and append it to 249, then repeat: 2493 / 625

Let's proceed to step 4:
When dividing 2493 by 625, we get 3 with a remainder of 618.
Write down 3 as next digit of the result. 
Result so far: 13.0
Subtracting 1875 from 2493 leaves us with 618.
Take the next digit (4) from the dividend and append it to 618, then repeat: 6184 / 625

Moving on to step 5:
625 can be fit into 6184 9 times, resulting in a remainder of 559.
Put 9 as the next digit of the answer. 
Result so far: 139.0
Deduct 5625 from 6184 and we're left with 559.
Bring next digit (0) of the dividend behind the 559 and repeat the process: 5590 / 625

Let's proceed to step 6:
625 goes into 5590 8 times with a remainder of 590.
The next digit of our result is 8. 
Result so far: 1398.0
The remainder is 590 after subtracting 5000 from 5590.
Grab the next digit (9) from the dividend, add it to 590, then carry on: 5909 / 625

On to step 7:
625 can be fit into 5909 9 times, resulting in a remainder of 284.
Write down 9 as next digit of the result. 
Result so far: 13989.0
The remainder is 284 after subtracting 5625 from 5909.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

On to step 8:
The number 625 fits into 2840 4 times, leaving a remainder of 340.
Record the quotient 4 as the next digit in the result. 
Result so far: 13989.4
If we subtract 2500 from 2840, we get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Step 9:
3400 divided by 625 is 5 with a remainder of 275.
Put 5 as the next digit of the answer. 
Result so far: 13989.45
Subtracting 3125 from 3400 leaves us 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 10:
625 goes into 2750 4 times with a remainder of 250.
The number 4 becomes the next digit in our result. 
Result so far: 13989.454
Deduct 2500 from 2750 and we're left with 250.
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 11:
The number 625 fits into 2500 4 times, leaving a remainder of 0.
The next digit of our result is 4. 
Result so far: 13989.4544
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 quotient of the division is 13989.4544, and the remainder is 0.0.
