We divide 78488409 by 173
Let's see how many times 173 fits into 78488409.

On to step 1:
7 divided by 173 is 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 173

On to step 2:
78 divided by 173 is 0 with a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 78 and we're left with 78.
Take the next digit (4) from the dividend and append it to 78, then repeat: 784 / 173

Moving on to step 3:
173 goes into 784 4 times with a remainder of 92.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtracting 692 from 784 leaves us with 92.
Bring next digit (8) of the dividend behind the 92 and repeat the process: 928 / 173

Advancing to step 4:
If we divide 928 by 173, we get 5 and a remainder of 63.
The number 5 becomes the next digit in our result. 
Result so far: 45.0
Subtracting 865 from 928 leaves us with 63.
Grab the next digit (8) from the dividend, add it to 63, then carry on: 638 / 173

Step 5:
If we divide 638 by 173, we get 3 and a remainder of 119.
Put 3 as the next digit of the answer. 
Result so far: 453.0
If we subtract 519 from 638, we get 119.
Grab the next digit (4) from the dividend, add it to 119, then carry on: 1194 / 173

Step 6:
173 can be fit into 1194 6 times, resulting in a remainder of 156.
Use 6 as the next digit of our solution. 
Result so far: 4536.0
The remainder is 156 after subtracting 1038 from 1194.
Append the next digit (0) from the dividend to 156 and continue with: 1560 / 173

Moving on to step 7:
When dividing 1560 by 173, we get 9 with a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 45369.0
Deduct 1557 from 1560 and we're left with 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 173

Moving on to step 8:
When dividing 39 by 173, we get 0 with a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 453690.0
Subtract 0 from 39 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 9:
173 can be fit into 390 2 times, resulting in a remainder of 44.
The number 2 becomes the next digit in our result. 
Result so far: 453690.2
If we subtract 346 from 390, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 10:
173 can be fit into 440 2 times, resulting in a remainder of 94.
Use 2 as the next digit of our solution. 
Result so far: 453690.22
Deduct 346 from 440 and we're left with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

In conclusion, the division gives 453690.22 with a balance of 0.094.
