Let's divide 178409 by 70
Our goal is to divide 178409 by 70.

Step 1:
If we divide 1 by 70, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 70

On to step 2:
When dividing 17 by 70, we get 0 with a remainder of 17.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 17 leaves us with 17.
Include the next digit (8) from the dividend after 17, then repeat: 178 / 70

On to step 3:
178 divided by 70 is 2 with a remainder of 38.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 140 from 178 to get 38.
Bring next digit (4) of the dividend behind the 38 and repeat the process: 384 / 70

Let's proceed to step 4:
If we divide 384 by 70, we get 5 and a remainder of 34.
Put 5 as the next digit of the answer. 
Result so far: 25.0
If we subtract 350 from 384, we get 34.
Fetch the next digit (0) from the dividend, attach it to 34 and continue: 340 / 70

Advancing to step 5:
The number 70 fits into 340 4 times, leaving a remainder of 60.
The number 4 becomes the next digit in our result. 
Result so far: 254.0
If we subtract 280 from 340, we get 60.
Grab the next digit (9) from the dividend, add it to 60, then carry on: 609 / 70

Let's proceed to step 6:
The number 70 fits into 609 8 times, leaving a remainder of 49.
Write down 8 as next digit of the result. 
Result so far: 2548.0
Subtracting 560 from 609 leaves us with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Step 7:
The number 70 fits into 490 7 times, leaving a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 2548.7
The remainder is 0 after subtracting 490 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 8:
When dividing 0 by 70, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 2548.7
Subtract 0 from 0 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.

On to step 9:
70 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 2548.7
If we take 0 away from 0, we end up with 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 2548.7, with a leftover of 0.0.
